RE: 4L60E Trans controller

[Carl Summers <InTech@writeme.com>]

Hiya Bruce,
     I, like many others on this list, enjoy what GM has spent so much time
and money developing....there are many people however that don't know what
to do with it....and while there are other controllers out there that market
their own "box", I agree with you that the power of a GM processor is hard
to argue with.....but, for others to agree with us they will probably have
to jump into it like we did....because we had to.....we couldn't get
satisfaction from outside suppliers of chips.....we believed they were
tuners...and as we all know that have done it, the vehicle needs to be in
front of you......so I want to say to all that look to any kind of software
out there, GM or not, you have to understand what you are changing before
you change or there could be detrimental damage to the components....engine
or trans.....a controller is a stupid box....changing some variables of the
controlls can be very simple via software and requires foresight....I feel
Bruce has been through as much suffering as many of us beginners and is
trying to save you the grief of dealing with unproven products....just keep
an open mind when looking at what you want to do and buy.....I for one have
yet to see anything as powerful as Delphi/GM, given the same
scenario...don't get me wrong...there are good controllers out there..but
you better know what your looking at and better yet, what they really do and
how to use them.....Bottom line....Grumpy never was Dopey....and I was too
sleepy to be bashful so I never met snow white.....well I guess I got
carried away...and now my kids are asleep so I guess this story
worked........zzzzzzzzzzzzzz

Kinda kills the fun of even having a gmecm list then doesn't it?.

I just got looking around some of the editing stuff I got, and the tunercat
editots for the PCMs I have include that.  I'll also, bet, that it cost me a
heck of a lot less then what you got in one car, that I can use in as many
cars as I want (that use the same pcm) by editing their pcms, rather then
throwing money at the problem.
  Just for instance,  Tunercat about $100, Needhams burner program $200,
couple new memcals (as in the case of the 8625), $100.  Now for a total of
$400 I can do all the engine and tranny stuff for a 8625 that I want.  If
instead of the spare memcals, I get a prom emulator then I can do the
laptop, instant (probably need to do a reboot for getting a cheap emulator)
reprogram for $200.

   I'm sure Ken Kelly's carputing would do something along these lines.
   The GMEPRO for PCMs also contains the tranny shift editing.  What is
kinda neat about GMEPRO, is that you can refine, edit, and create your own
editing programs, so that if you say want to just do fuel, and WOT fuel, you
can make a file just for those items, and have your laptop + emulator, and
go out and dial in changes is just moments, and be off again.   I'm sure the
flash stuff is even easier, just I haven't had a car to play with yet.

I've used GMEPRO, and Tunercat stuff, and have no problems referring people
to them.  I do have some other stuff, that well, really isn't cost
effective, and trying to get a response from the seller is a waste of
time...  I can't comment on Ken Kellys stuff, from a users viewpoint.
  And, I can get junkyards pcms and ecms for alot less, then a replacement
what ever your selling costs.
