Hells yes.  We should possibly have a discussion board
on the project website at some point, for mutual
experience with installations, a designer's corner for
those who want to discuss hardware implementations
(after we get a few basic modules up and running,
perhaps we should post an API?), etc.  And an adjunct
of that could be people posting videos of their
vehicles running with the system, or demonstrating
functionality (you could make a movie of a timing
light on a running engine with closed-loop spark
timing, shoot some water in the intake, and see the
ion sensing unit advance the timing, allowing it to
retard after the water cleared out of the intake
system).

I'm going to use this ECU, hopefully with closed-loop
spark, on the EFI conversion for my motorcycle, and if
I still have it (or have gotten another one), on my
'85 RX-7 GSL-SE (I would probably start off using it
with stock sensors and a stock or 2nd gen intake
manifold/TB); on the RX-7 I will try to implement a
water injection system to allow leaner running and
improved fuel economy all around.

To say I'm quite jazzed about this project is an
understatement.  :D

So just where do you guys buy your injector connectors at?  I know that
Del City sells them for $1.00 each, but I'm looking for the nicer ones
with the wire bail over the top, like the Bosch ones have.

I have seen the Megasquirt suppliers for the injector connectors, but at
$5.00 each, that's too pricy when I looking to buy about 100 of them.

Any sources?....Tim.

Have you used the connectors from Del City?  I just looked on their web
site.  It looks like for $.87 they would be a better bargain than going to
the junk yard like I have done in the past.  I can't get harnesses for any
less than $20 around here.  That means several dollars per connector.  I'll
be stopping that!

Thanks for the lead.

If you're looking for the standard connectors for a Bosch style injector, 
Motec sells them (don't know the price).  They're LK-2 connectors.

Yes, I have used them but the Del City ones are a pain to disconnect.
The Bosch style ones that I'm talking about (same as the Megasquirt
supplier's use) have a bail over the top, making it very easy to
disconnect....Tim.

If they are no more pain than the stock units I could live with that.  I
just wanted to make sure they are complete with terminals and short leads to
splice into a harness.  If I remember right, the stock connectors are no
easy thing to get disconnected.

I'll have to look at the Megasquirt stuff and see what you mean on those
units.

Thanks for the feedback.

The Interceptor CPU boards arrived from China today. I will be stuffing
the first one and soldering it over the next couple of days. Then comes
the fun of doing the initial programming/testing. If it works out well I
will have the ADC/DAC daughter card fabbed.

FYI

As usual (being an Engineer) I have kept looking for the 'ideal'
components for the ECU design - the Interceptor job is simpler so it's
not quite as 'critical'. Yesterday I came across this gem:
http://www.analog.com/en/prod/0,,762_0_ADUC7020,00.html it has most of
what I would ideally like to have - so this week I believe I will
attempt to design my first surface mount circuit board using 3 of these
chips.

I got my GM MAF the other day, so I am ready to start
data logging when the boards are ready.  Shoot me an
email when you have one ready to go.  :)  I can get
you details on the pinout and use of the various bits
inside the flapper if that'll help, too.  Can we find
a way to get the box to burn off the junk on the hot
wire MAF after key-off?  I think that all hot wire
MAFs from the past 10 years or so have that feature
built in to the ECU, and it would be helpful if we
could handle that with the MCU.  I'm really jazzed
about the flapper replacement project, and am eager to
start data logging.  :D

Cool.  :D  I am really digging the amount of
processing power and ADC channels we can fit into a
small space without it costing an arm and a leg. 
Maybe eventually I can start working on some runtime
code to allow the ECU to work like current-gen OE
units; they actually have a mathematical model of the
engine and its behavior, and fuel based on what the
model outputs.  Seems to give much finer control over
power and emissions, and it would be incredibly cool
to be able to play around with that stuff without
having to work for a university or a Tier 1.  :D

hi.  i just registered with diy efi today.  i never sent a post.  i don't 
know what you are talking about.  therefore whoever you think you are 
talking to ain't hearing you.  all i really wanna do is set up a cheap 
runable tbi setup on my 2 engined boat.  you sound like you are way beyond 
that.  good luck.  derek.

Derek,
One EFI newbie to another: You are right, these guys ARE beyond most of us, 
many work in the industry.  Be Cool.  They understand and try to help us 
newbies - as long as you are polite and do your homework.

Lurk and learn, see how it's done, be patient and pay attention, there are 
lots of other guys in this group doing simpler projects who will be able to 
help.

These advanced guys are actually designing and building NEW systems.  But 
there IS plenty of help here IF you approach it right.  Read the archives, 
see how it's done.  No fooling.

Ernie B.

The mailing list gets all kinds, from those trying to
find simple ways to remap their stock systems, on to
guys who want to take a GM injection system and adapt
it to their non-EFI car, through guys who build and
program their own MegaSquirt EFI controllers, up to
guys who reverse-engineer old systems and develop new
ones.  I believe we have an archive, and there should
be plenty of info to help the young man along on his
quest already there for the taking.  Here is the
recent archive page: 
<http://www.diy-efi.org/pipermail/diy_efi/>  It
doesn't seem to be searchable, although you can
download the archives by month and then just text
search for info (is there an online search feature? 
Someone correct me please if I am wrong here).

As an aside, Ernest, would you be interested in having
more usable features on a replacement turbo ECU than
the stock one came with?  The closed-loop spark timing
would be a real boon on a turbo bike, as would the
ability to detect ping/knock that is sub-audible (both
via ion sensing).  It should be possible to fit an
electronic wastegate, so the stock ECU can control
boost (it could be set up, for instance, to help
smooth out the transition for the 500 when it comes on
boost, by letting the boost pressure ramp up over a
few seconds rather than having it hit all at once; it
could also be programmed in the other direction, to
work as a "snap valve" (mechanical wastegates open
progressively as they approach the target boost
pressure, then open the wastegate fully when the peak
boost setting is exceeded)).  I get the feeling that
might be a popular daughterboard project, as it will
add a new dimension of tunability to any turbo'd bike.
 Heck, you could even set "progressive boost" for
street riding/commuting, and switch over to "snap
valve" for Saturday nights at the dragstrip.  All
you'd need would be a laptop...

2 engine boat - sounds like a real 'fun' (read that as spooky fast)
ride :-)

I am indeed playing in new areas/designing my own ECU - your needs may
be met by something already off the shelf today - megasquirt comes
immediately to mind. That may be the ticket for you. At least today so
to speak - my stuff is not ready for prime time in any way - serious
assembly required :-) A few more months and that will change - today
it's still rocket surgery :-)

Laptop? I'm planning on having sety profiles selectable on the dash 
computer I'm building ;-)

Steven:   I've followed Megasquirt for quite a while and it looks 
impressive.   I also know that setting up the operating parameters of an ECM 
is not very easy.  Have you done one and how long does it take to set one up 
where it makes a good running engine?  Can a beginner program one?    Thanks
Jim

I have not yet set up a megasquirt - so I am not one which can answer
your question effectively. Hopefully someone else on the list can answer
you.

Hello James,

The base code version for the MS1 is without doubt one of the most basic and minimalistic EFI controllers available when it comes to the operating parameters. How long it takes to get one operational depends on the engine type. Quite often, the default settings are sufficient to get an engine running, although tuning will be required. 

I have seen beginners driving their vehicles within 30 minutes of first turning the key after a new installation.

Bruce     Glad to see you were online---.   I've been attempting to get 
started with a 749 ECM and the Typhoon $58.   That is sure not easy to tune 
and there is very little information for beginners.  All the support aids go 
right into the most technical parts of using the equipment---for example 
opening the program files and XDF definitions.   I was curious at how the 
screen set-ups and start ups were with MS because it seeded to me that those 
users woudl have been more unskilled users.  I now have about three days of 
reading and a thousand dollars of equipment and am really nowhere yet. 
I'll get there but it's sure not fast!!
Thanks for the reply.

Subject: [Diy_efi] GM timing signals
In-Reply-To: <F2C29ABA4D75714AAFC89187D9D8F29328B0CC@THUNDERBIRD.usa.Arm.com>
Message-ID: <BAY122-DAV2E2B3A41731451CFA8E95B07D0@phx.gbl>

All,
I have a question and hopefully a fairly simple one.

I play around with the GM TBI systems, mostly the 7747 and 8746.

I have used the 7747 on a lot of different motors to include 4 cylinders.
I run the whole system with the stock 8 pin EST module.

My latest conversion is using the 7747 ECM and the DIS system from the 2.2
cavalier. I am running the system on a 1275 A+ motor in an older Mini. I use
it to drive the SPI(TBI) Mini throttle body and single injector by just
tying the 2 injectors signal wires together Since the pulses are alternated
from one inj to the other anyway.. The ECM just thinks there's 2.

When I researched this project, it appeared on the surface that the required
timing signals and the wiring were all interchangeable. But obviously it was
not that simple. It seems that the ECM timing signal is opposite of what DIS
wants to see. When I start the motor it goes to full advance and stays
there. At present I simply have the bypass disconnected, removed code 42 and
set the base timing to 15?. This gives me a total advance of about 30? in
limp home so it is at least drivable.

Does anyone have any specs on the differences in the timing signal from the
7/8 pin to the DIS?

I have read a lot of the data on the GM and DIS posted on the Megasquirt
board but it didn't really specify anything.

I even tried to read the patents I could find but they seemed really
generic.

I'm hoping there's a simple solution like just inverting the signal with a
switching transistor.(I can hope)

Any help is appreciated.

Adam,
Absolutely!  And I know more than a few CXTC owners who would be right in 
there with me, am in regular touch with the fellow who ran a CXTC 
aftermarket shop for many years.

Not sure I know what you mean about "closed loop spark timing" tho, thought 
that had only to do with mixture?  Tho can see why constantly variable 
timing would be key to success when going for ultimate performance out of 
these motors.

I've got your book on my table to start reading again, now that I have more 
questions and am slowly getting a feel for the possibilities.

Also have Yam Venture Royale project that REALLY needs EFI, tho non-turbo to 
start with; carbs are big and sophisticated but per typical Yam parts 
pricing, one rebuild would pay for half of a MegaSquirt, or?  Definitely 
looking for ideas & suggestions on that one.

Thanks!
Ernest B.

Hi James,

I would recommend going to the megamanual site (www.megamanual.com) and spend some time going thru the documentation there. For the software, download MegaTune and/or MegaTunix and run the applications to see how the menus are laid out.

Be warned there is a lot of information on the megamanual site, I would focus on the installation and tuning documents first, since a knowledge on EFI at a basic level is essential for success.

Since I've never done any SMT work I at present have no real
understanding of the pro's/con's of the packaging. Any ideas in this
area I'd certainly like to hear.

I would very much recommend the LQFP.  Trying to work with the LFCSP is a 
bit tough unless you are pretty skilled with a rework station.  Certainly 
not something that can just be soldered with your standard pencil tip.

LQFP packages are pretty good for hand soldering.  Not as nice as a through 
hole dip.. but then they're generally much better devices, so worth the 
extra effort.

In-Reply-To: <20070312233913.D5E4128D9D@smtp-ext-01.mx.pitdc1.expedient.net>

I have been going nuts trying to get my '86 Corvette working with the  
DataMaster software so I can get someone to adjust a custom chip for  
me.  I have a very simple ALDL interface cable that consists of three  
wires (pins A, E, and M) soldered to the BACK of the ALDL port, which  
run through the ALDL adapter circuit, to a serial cable to my PC.   
This setup worked fine with WinALDL, as far as I could tell - I was  
getting reasonable data when logging.

I also have a Prominator with a copy of the stock PROM installed.

First thing with the DataMaster package is that 85/86 Vettes require  
a "10k resistor modification" which I found the circuit for on the  
'net.  I added the resistor inline going from pin B to the wire  
coming from pin A.  Once I did this, DataMaster was able to test and  
identify the PCM.

However... every time I try to read data from it, I get a "No PCM  
Sync" message and a counting timer.  No data.

Any thoughts?  The people at DataMaster have been less than helpful;  
I seem to get secretaries rather than support staff.

Thanks.

Steven,
    As usual there are pros and cons both ways -
 the LQFP package would be the most straight-forward to use, and though 
the lead pitch is fine it can be hand soldered - but carefully with a 
very small tip and good flux - for hand soldering SMT parts a small 
small bottle of low residue liquid flux, or a syringe of paste flux is a 
great help.
the cons of this package are that it cannot dissipate heat as readily 
(heat dissipation is mainly through the legs) and it occupies more board 
space.

the LFCSP package occupies much less board space and has much better 
heat dissipation through the metal slug in its base.
The cons of this package are:
It cannot be hand mounted or re-worked (the pads are under the chip) - 
it requires a reflow oven to load and specialised equipment to remove.
The metal slug in the base must be soldered to an earthed pad on the 
board, with ground plane on all layers and at least 9 vias (plated 
through holes about 25thou diameter) to allow the excess solder to wick 
through the board, and pull the chip down into close contact with the PCB.

In my job we use both package types as well as special quad flat packs 
with a thermal slug in the base.......

For your application I would suggest that the LQFP is probably the 
better option.

Regards
Bill

The sensor is a vw (bosch part #) for the less expensive non ntk sensors.
I ordered one last week for a replacement for my innovate lm-1. It was $52
with tax from Napa. There was somewhere online a bosch sensor could be
shipped for less than $35. VW sensor lists for above 150 at the dealer.
These are a couple of diy kits.

You are looking for a sensor for a 1.8T engine. These are found in GTI,
Golf, Jetta, Passats. I'll check and see if I can dig up an exact part
number as I have ordered the same before.

mmm, Yes "me too" I would also be interested in a low cost sensor
as a secondary unit for a proof of concept multiple fuel system,

I have a homeless Nissan VH41DE engine that I want to get running on
a test stand.  The plan is to manage it with an old TEC2  computer.
Does anyone know if the Nissan VH41DE engine uses a 60-2 crank signal?
That would really make my day.
TIA,

Message-ID: <BAY122-DAV15E26A7411ED88C9CEA534B0740@phx.gbl>

Just a little update incase anyone else decides to play with a GM ECM....
I am using the 7747 TBI V8 ecm and the 2.2 cavalier DIS system on a 1275 4
cyl mini engine with the SPI(TBI) manifold and TB.

I was having trouble working out the timing settings so the 7747 would drive
the DIS properly.
After reading the GMECM paper Steve linked to I started playing with the max
spark, max retard and warm bias. I also decided to call on the 7747 expert
RBob for guidance.

I was manually editing the timing settings in hex editor and also set the
warm bias to 70? and finally got the thing to control the timing properly.
 Then Bob shot me a reply and recommended I go with initial timing vice warm
bias as I was having the spark table showing negative numbers.

All worked good and the table displays correctly.

I have the max retard to -70? max advance to 80?...I set it to AE which is
supposed to be -10? but given the display parameters in tunerpro it still
displays as 80?(90-10=80). 
And the initial advance is set to 70?.

So now the fuel and timing are working correctly and I am getting it dialed
in.
With some help from a mini forum I was able to modify the 5 wire throttle
stepper to be driven by the IAC signal and now properly controls idle speed
as well.

The last thing I am looking to do is add the ESC and knock sensor back in.

Then later I would like to add a VW GT40 supercharger and run the 7749 turbo
ECM. Or possible the later 7427 PCM or maybe just the EBL on a 7747......so
many choices, so little time!!

Thanks for the assist!

     any older site closer to gm perhaps ?

ooorrrps, I bin caught !

<hrrrm> yes, though only when I have leftovers or oddments that people
said they wanted then changed their minds, ie I'm not there all the time,
as it happens I have a few oddments in the box, loom, old model, some
cable etc and a couple of new ones I might post this w/end, all depends
on what orders are paid for by end of business tomorrow,

curious why u ask ?

Isn't that just one of the front loaded TPAs used directly on a module 
connector? Wouldn't you be better off trying to source it from the tier 
level supplier? (Delphi, AMP, Tyco, Yazaki etc etc ) Does it have a small 
symbol cast into the plastic on it somewhere? I've never found the PN# cast 
into parts like that of much use at all. Last time I ordered a number cast 
into a plastic connector I got a frame rail for a Kodiak MD truck!

Ah ha,

I'm not actually trying to get that part, I manufacture an upgrade version as
per my web link but the original one pictured has the letters "GM" on
the right hand side underlined (can just see it in that pic), so I doubt its another supplier.

My aim is to find what other models/years in USA used that part, locate the dealers
and offer the upgraded part. So far not much luck except the cadillac has
come up as a possible, so now I am looking for any cadillac specific forums or
dealers in USA that might be open to orderingd a superior part from Australia ?

Subject: [Diy_efi] Problem with TPS on aftermarket ecu
Message-ID: <590205.9792.qm@web50304.mail.re2.yahoo.com>

Hello,

gee its quiet in here.

I have a problem with my TPS and I'm running out of ideas. Perhaps someone else on here knows whats going on.

The TPS is not reading correctly in the ecu. The ecu is a Walbro BIKE400. Probably haven't heard of it but thats not real important as it uses basically the same principals as most ecu's when it comes to TPS.

I have wired the TPS correctly. It is a standard GMH 3 wire TPS. +5v, GND, TPSsig.

The throttle movement is correct. I could calibrate the opening 0% and 100% without problems. In the datalogging software, the throttle movement works correctly. WOT logs 100% throttle etc. The problem is that the 'dthrottle' value does not change. It remains at 0 with the occasional movement to 1 or so. Just like little blips of interference (noise). Basically the ecu thinks that, although the throttle is moving, there is no change. The result is no accellerator enrichment. 

If anyone knows why it is doing this, it would be a great help.

thank you

Damian

The simplest explanation is that TPSSig is either not connected or 
poorly connected to the ECU.

If I read the original post correctly, the data log shows that %throttle
changes as he opens and closes the throttle.  In the same log, however,
while the throttle position itself is changing, the delta throttle value
doesn't change.  Damian, is this correct?

If so then the connection from the TPS to the computer must be OK.
delta TPS is a calculated, not measured, value.  It only takes on a
value while the TPS is changing rapidly so by definition is only non
zero for a short period of time.  My question would be what is the
sampling rate of your datalogger?  If you only get a couple data reports
per second then it's entirely possible that delta TPS is changing values
correctly but is being missed in the log.

Or, is there a constant that sets the decay rate of delta TPS that is
causing it to decay too quickly?  Is there a symptom (stumble or
hesitation) that accompanies the lack of delta TPS?

Damian,
Mostly I lurk and learn on this group, but on this subject I may have some 
relevant experience, since you are looking for a non-obvious answer (having 
covered all of those already, heh.)  A few years ago I was trouble-shooting 
some intermittent sensor wiring, and got it down to one wire.  Connectors 
were good on both ends, but still no continuity.  Frustrated, I broke that 
wire out of the bundle, expecting to find a hidden break, but nothing 
visible, argh!  Knowing that I was going to replace it anyway, I began 
cutting into it in segments and testing each section, until I reduced the 
non-continuous run to a span of a foot or so.  Then I stripped that section 
inch by inch - to find a clean break in the solid copper strand, a perfectly 
square cut, no damage visible even under magnification.  Meaning that it had 
been mfgd that way, difficult as it seems that would have been.  I can 
imagine that as-new continuity testing would have passed, since the ends 
touched.

Anyway, I send this not as a likelihood, but merely as citation of a very 
rare example.  So weird that I must proclaim my own present sanity [:oj and 
restate the factual nature of the tale; I was an instrumentation tech at 
Edwards AFB, so, while not an engineer by any stretch, I've got a pretty 
good grasp of the basics.  Meaning that I know how unusual such a 
discontinuity is.  But it did happen at least once.  Meaning that it could 
happen again, even tho I've never heard of anyone else finding such an 
anamoly:  Bad splices, loose crimps, hidden corrosion, yes, but never a 
clean square shear INSIDE undamaged & unmarked insulation.

I can say that in the 25 years since I have been exposed to all sorts of
wiring on industrial and automotive I have seen similar issues on about
such 5 occasions on multistrand wires.

The most common is corrosion of the (multi strand) wire  without much
evidence externally except perhaps an almost imperceptible bulge. Breaks
in telecoms single strand are far more common however, I have lost
count of those.

I am guessing that the PVC polymer may not be totally homogenous and
during the moulding process some monomer may be trapped inside the
wire, the presence of heat, especially in automotives, might well cause the
vinyl chloride to release chlorine, attacking the wire forming Copper Chloride
and either higher resistance or a complete loss of continuity.

On older cars the PVC insulation hardens and cracks and in the engine
bay the corrosion seems to be sulphate based, I have seen a couple of
light blue dust from sharp edges of cables where it has cracked, I am guessing
that long exposure to battery gassing might have caused this,

So not so uncommon me thinks,

mmm, Now that I think of it, the other likely failure mechanism relates to where the loom
is bundled and compressed where it passes through the firewall. On my model, there is a bunch
of wires from the various EFI sensors as well as drive lines to the injectors all bundled together
and about 150 to 200mm from the exhaust manifold and turbo. So on hard runs the hot air
from that is always passing over this tight bundle, imaging that the PVC breaks down and
thin cracks start to appear, then imagine the first rains and puddles throw up water and
it seeps its way into the cracks.

One wonders if this might allow the pulses and back emf from the injectors to find a path
to the analog sensor cables, especially if the copper chloride/copper sulphate as a result
of corrosion is moistened,

This might well explain odd things my ECU does as it sometimes acts as if the AFM is
out of whack, ie Trips the ECU to overfuel - which is a common issue with the Bosch/Hitachi
ECU on a 20 year old car, <sigh>

my favourite one was found in a toy I repaired.

corrosion in the battery compartment got into the wire that ran about 4
inches from there to the power switch.

replacement of the wire didnt fix it.

what did, was replacing the switch.

closer examination revealed that the corrosion had gone under the
insulation, wicked along the wire internally, and escaped into the
switch, where it had destroyed the contacts.

never seen anything like it.

These last couple of posts have been some good food for thought. The 21 year old emissions/control harness in my car mught be contributing to some of the puzzling ways my engine seems to change temperament day to day and season to season. Here in the Gulf Coast of Texas, USA we see some pretty wide humidity swings. It can range from 10% sometimes during the winter months to 90-100% during the summer. Most of the time I attribute the performance change(butt dyno of course) to changes in barometric pressure but I was never really convinced. Could it possibly be changes in conductivity due to changes in the moisture level of the air? Sounds like it might be a good idea to pull the complete harness and do a complete inspection and rebuild.

Thanks for all the technical input on the corrosion mechanisms.

Mike

To insulate wiring and small hoses in hot areas I've been making good use of 
the stuff used to double-insulate spark plug wires, fiberglass sleeving in 
silicon rubber.  Most autoparts stores are beginning to  handle the stuff 
now, not expensive. A friend who runs a car at Bonneville turned me on to 
it.  Diesel injector and turbo rebuild shops also handle it, or something 
similar.

Message-ID: <1175346849.19798.15.camel@wopr.donegan.org>

Being an Engineer I have been trying to find an optimal mix of parts for
extreme cost effectiveness and high performance. I have played with
PIC's from Microchip, PSOC's from Cypress, ARM's from NXP/Phillips and
an interesting ARM thing from Analog Devices called an ADUC. I have also
been playing with FPGA type things - specifically the MAX family of
CPLD's from Altera. I am beginning to believe a combination of ADUC and
MAX 7000S will be the correct mix for the full blown EFI computer and
PSOC's will be the answer for the Interceptor. Given that the list has
been dead quiet for a while I figured wasting your time/bandwidth with
an update would not be a problem :-) To put this in perspective - a
MAX7000S in industrial temp range costs ~19$, the ADUC about 10$ - this
makes a sub 100$ EFI computer a possibility...

Steven,

Have you had a look at the TMS470 from Texas Instrument? It's also an ARM
processor and seems to have a nice set of features for EFI.

I have not yet - but will do so now :-) You do realize you're feeding
the Engineer never getting to closure part of me :-)

If you could make an ECU test bench to fool the OBD2 ECU, I imagine you
could hide it the trunk. You bring up an interesting point.  Our test for 
OBD2
cars is simply checking for codes.  If no codes are stored you pass!
If the car is pre-OBD2, they put it on the rollers with a gas analyser
probe up the pipe.  I guess a great deal depends
on the tests used in your area.

I don't know if this has come up before, but for those who have OBD2 GM 
vehicles and have used a different ECU to allow you to tune it, what can you 
do to pass emissions?  The emissions check where I live is a simple plug in 
test to the computer where they just check for codes and see if it lists as 
"ready" on the emissions pre-tests.  SO, is it possible to emulate an OBD2 
port on the vehicle?  Or even hack a 2nd obd2 ecu to just say all is well? 
Swapping back to the old ecu is not possible as it isn't hackable nor could 
it even the run the engine if I wanted it to.  Thanks.
