James" Subject: Atmel & List Stirring Hi Bernd, Thanks for posting your letter. At the risk of incurring EEC and diy_ list ire, I feel that the intellectual questioning you've brought up is very interesting, especially when commercial design becomes more complex with OBD and obfuscated by design to thwart modifications. Perhaps the time is approaching for a controller box that plugs into the EEC harness and is easily programmed from open architecture software. Of course this is a lot like the diy-efi project, but from an observers standpoint, I believe it (diy) required to much upfront programming effort, for first you had to become a Linux expert, then a Motorola guru. I would hope for a DOS or Windows based programing approach, so that discussion would flow more about engine control algorithms and not Tarring and Kernaling. As the prices drop and more attractive silicon for an engine controllers becomes available, it would seem that there might be an advantage to separating cylinders, like two identical 4 cylinder controller's for a V8. Two ignition sensors (like Pertronix modules switching resistor loads to provide position logic) and parallel mass air flow or 2- MAF units for less air flow loss. Or one controller for part throttle and another for full throttle. Just curious about multiple processors, having thought about using some of the faster PIC,s for each cylinder. Actually have saved an old John Deere tractor motor and mower to try this on. Thanks for listening guys, and hope to hear discussion on merits of low cost, easily programmed, multiple processor use. Thanks all (please no flames (thats an engine pun)) Jack - ---------------------------------------------------------------------------- To unsubscribe from diy_efi, send "unsubscribe diy_efi" (without the quotes) in the body of a message (not the subject) to majordomo@xxx.org ------------------------------ Date: Tue, 29 Feb 2000 12:13:07 -0500 From: "nacelp" Subject: Re: New files on FTP site 88 vin C 3.8L 8253 is one application, Grumpy - ----- Original Message ----- From: Shannen Durphey To: Sent: Tuesday, February 29, 2000 10:07 AM Subject: Re: New files on FTP site > Give me a make-n-model, I'll look around. > Shannen > > Peter Gargano wrote: > > > > Shannen, this info (you posted to DIY_EFI) is fantastic... > > Is there similar GM information available on the "Fast Start" > > DIS/DFI system? > > > > > > ftp://ftp.diy-efi.org/incoming/lt5dis_01.zip 1067389 Feb 28 01:14 > > ftp://ftp.diy-efi.org/incoming/lt5dis_01.zip 925458 Feb 28 01:09 > > > > Shannen Durphey wrote: > > > > > > Pictures of 93 LT5 DIS unit. 2 .zip files, about 2 meg total.

FWIW, I have a Haltech AF30 digital A/F indicator spliced into the O2 circuit of my GM PCM. I also have an isolation switch which can decouple this device from the PCM's O2 circuit. Using an ALDL scanner I can monitor the effect of "connected" versus "unconnected" upon the PCM's interpretation of the O2 signal. In my particular case the PCM's interpretation, with the device connected, is biased approximately +100mv versus the unconnected state. Measurable, but not noticeable to a driver. I would think that you should be safe, as long as you stay away from the real "cheapies" and query the vendor's tech people regarding this issue before purchase. Walt. Date: Mon, 28 Feb 2000 09:11:19 -0500 From: Aribert_Neumann@xxx.ca Subject: Wire up an "A/F gage" w/o effecting existing control system? I asked this question a while back as part of a larger series of questions but did not get a response. Can I hook up a cheapie "A/F gage" like a Cyberdyne brand by simply splicing into the wire from my O2 sensor or will the A/F gage degrade the signal from the O2 sensor to such an extent that I need to use an A / B switch to switch the O2 signal between the A/F gage and the ECU? FWIW, I am using a Bosch Motronic M1.5 engine management system (originally on a 2.0L GME engine) grafted onto a 2.3L Isuzu engine. - ---------------------------------------------------------------------------- To unsubscribe from diy_efi, send "unsubscribe diy_efi" (without the quotes) in the body of a message (not the subject) to majordomo@xxx.org ------------------------------ Date: Tue, 29 Feb 2000 22:39:32 -0300 From: "Diego Martin Monteverde" Subject: Motorola chip and more >Date: Mon, 28 Feb 2000 02:20:18 -0800 >From: Carl Summers >Subject: Motorola chip and more > >Hi Folks, > Have any of you had the opportunity to use the new 68555 chip destined >to be in the new Automotive computers?????

I think that it the P/N, it is a really hot chip, except you can't get them unless you are a major manufacture at last I heard. Also it uses BGA (Ball Grid Array) for soldering to the PCB and you need a production house to do it or some odd sockets. It is based on the PowerPC and has a lot more 'stuff' crammed on it. For the ISO Smart card information try www.dr7.com I think it is. Lots of information for those that want to learn about ISO cards and other interesting things.
