For sources on such things as well as single board computers and evaluation boards you should really check out "Circuit Cellar Ink - The Computer Applications Journal". This magazine is chock full of people using micros to do *real* things. Also, I'm sure they would be interested in paying someone to write an article on an EFI project. The magazine should be available at any good magazine shop.

PADS released a shareware version a couple of years ago. It was a version of the last 16 bit system that they produced with limited component count in schematic and PCB. They now sell only 32 bit versions called WORK and PERFORM but the shareware version is quite usable. I think the 68k design would exceed the limits of that version but I haven't tried it. It's available on Simtel and mirrors. Steve.

The injector/regulator assembly on these throttle bodies come off quite nicely, and I've had good luck using a throttle from a standard 2.5L GM engine. A chunk of aluminum can be used to replace the stock 'air horn' (the part with the injector and regulator) with a more suitable one for MPFI applications. -Dale From owner-diy_efi Mon Nov 7 17:14:36 1994 Received: by coulomb.eng.ohio-state.edu (920330.SGI/920502.SGI) id AA04148; Mon, 7 Nov 94 17:14:36 GMT Received: from wotan.compaq.com by coulomb.eng.ohio-state.edu via SMTP (920330.SGI/920502.SGI) for /usr/local/mail/majordomo-1.92/wrapper resend -p bulk -M 10000 -l Diy_Efi -f Diy_Efi-Owner -h coulomb.eng.ohio-state.edu -s -r DIY_EFI diy_efi-outgoing id AA04143; Mon, 7 Nov 94 12:14:19 -0500 Received: from twisto.eng.hou.compaq.com by wotan.compaq.com with smtp (Smail3.1.28.1 #12) id m0r4XUh-000vInC; Mon, 7 Nov 94 11:04 CST Received: from bangate.compaq.com by twisto.eng.hou.compaq.com with smtp (Smail3.1.28.1 #10) id m0r4XSZ-000uH6C; Mon, 7 Nov 94 11:02 CST Message-Id: Received: by bangate.compaq.com with VINES ; Mon, 7 Nov 94 11:02:24 CST Date: Mon, 7 Nov 94 10:19:14 CST From: Steve=Ravet%Prj=Eng%PCPD=Hou@bangate.compaq.com Subject: re: admin: group purchase of chips To: diy_efi Cc: Sender: owner-diy_efi Precedence: bulk Reply-To: DIY_EFI John S Gwynne Wrote: | As we have seen posted in the last few days, there are a number of chip | available, but only in quantity, that would make our EFI designs | smaller, more reliable, and easier to build.

I have seen ads from several places that will print 2 double sided boards w/plated thru holes for ~$90 total (ie $45 apiece). I'm sure it'd be cheaper in larger quantity. Maybe once the group buy parts have been selected, we could get a board design put together and buy boards in quantity also?.... So for now, lets see those suggestions for parts.... --steve From owner-diy_efi Mon Nov 7 17:33:01 1994 Received: by coulomb.eng.ohio-state.edu (920330.SGI/920502.SGI) id AA04183; Mon, 7 Nov 94 17:33:01 GMT Received: from relay2.UU.NET by coulomb.eng.ohio-state.edu via SMTP (920330.SGI/920502.SGI) for /usr/local/mail/majordomo-1.92/wrapper resend -p bulk -M 10000 -l Diy_Efi -f Diy_Efi-Owner -h coulomb.eng.ohio-state.edu -s -r DIY_EFI diy_efi-outgoing id AA04178; Mon, 7 Nov 94 12:32:58 -0500 Received: from offramp.dsccc.com by relay2.UU.NET with SMTP id QQxpac02771; Mon, 7 Nov 1994 12:32:21 -0500 Received: by offramp.dsccc.com (5.67b/SMI-V1.8) id AA00232; Mon, 7 Nov 1994 11:32:58 -0600 Received: from onramp(192.245.102.129) by offramp via smap (V1.3mjr) id sma000221; Mon Nov 7 11:32:45 1994 Received: from optilink.dsccc.com by camelot.dsccc.com (5.65c/SMI-V1.8) id AA29627; Mon, 7 Nov 1994 11:33:08 -0600 Received: from montreal by optilink.dsccc.com (4.1/SMI-4.0) id AA12389; Mon, 7 Nov 94 09:31:47 PST From: marrone@optilink.dsccc.com (Frank Marrone) Message-Id: <9411070928.ZM1378@montreal> Date: Mon, 7 Nov 1994 09:28:00 -0800 In-Reply-To: Jeffrey S Armfield "Re : Small throttle body" (Nov 7, 9:11am) References: <199411071411.JAA20614@mn.ecn.purdue.edu> X-Mailer: Z-Mail (3.0.1 23feb94) To: DIY_EFI Subject: Re: Re : Small throttle body Content-Type: text/plain; charset=us-ascii Mime-Version: 1.0 Sender: owner-diy_efi Precedence: bulk Reply-To: DIY_EFI Thanks for the leads! -- Frank Marrone at marrone@optilink.dsccc.com 1965 Sunbeam Tiger B9471116 1960 Sunbeam Alpine Series I B9009330 From owner-diy_efi Mon Nov 7 19:52:44 1994 Received: by coulomb.eng.ohio-state.edu (920330.SGI/920502.SGI) id AA04539; Mon, 7 Nov 94 19:52:44 GMT Received: from slopoke.mlb.semi.harris.com by coulomb.eng.ohio-state.edu via SMTP (920330.SGI/920502.SGI) for /usr/local/mail/majordomo-1.92/wrapper resend -p bulk -M 10000 -l Diy_Efi -f Diy_Efi-Owner -h coulomb.eng.ohio-state.edu -s -r DIY_EFI diy_efi-outgoing id AA04534; Mon, 7 Nov 94 14:52:41 -0500 Received: from billy.mlb.semi.harris.com by slopoke.mlb.semi.harris.com (4.0/SMI-4.0) id AA11762; Mon, 7 Nov 94 14:52:31 EST Received: by billy.mlb.semi.harris.com (4.1/SMI-4.1-jmb) id AA07232; Mon, 7 Nov 94 14:52:30 EST Date: Mon, 7 Nov 94 14:52:30 EST From: jws@mlb.semi.harris.com (James W.

They were down for an "Engineering Excellence Workshop" and were running a demo of an integrated knock sensor signal processor. This thing (HIP9010) is controlled by a microprocessor bus port, and does programmable gain, filtering, windowing and integration. It produces an analog output voltage for knock amplitude. One of the guys had a PC/Windows control demo running the IC against a simulated sensor knock waveform generated from a digital recording. Pretty spiffy. The designers have very little automotive (i.e. greasy bloody knuckles) experience; I talked to them for a while about my various mailing list lurkings and my impressions of the garage tinkering and aftermarket developments I see ongoing. They also had an eval board for the J1850 single wire automotive bus interface products. They seemed apprehensive about opening themselves up to a deluge of e-mail, but if anybody has the urge to discuss these devices I am not so shy. I broached the subject of samples to them; I think that discreet inquiries could be handled, if it doesn't become a scene from a nature show.
