Re: Adapting GM ECM to Chrysler Turbo

[Thomas McCabe <mccabet@mediaone.net>]

I don't have it handy as I have to go outside and read it.  The SBEC/SMEC
is a '88/'89 vintage.  The engine is an '88 2.2L Turbo II in a '90 Caravan
w/ '89 Electronics.  My current SMEC is a '89 2.2 Turbo I unit.  I have a
2.2 Turbo I SMEC from an '88 Shadow, but I thing the O2 input is bad as it
is always rich and never fluctuates.

What program do you have?  Can you share any info so I can pursue
programing a SMEC to meet the requirements I have?

Thanks for the reply, I'll get some numbers tomorrow after I dig the
vehicle out of the 3 - 6" snow were supposed to get tonight.

Thanks Again!
Tom McCabe
