Re: Adapting GM ECM to Chrysler Turbo

["Programmer" <nwester@eidnet.org>]

I have 18 reads right now--my biggest grief with these things is the
silicone goo they've got the boxes sealed in. Takes a minimum hour
to get to the PROM. Once you get me the number, I can tell you if I've got
that one on file or not...otherwise, I guess you could send me your
computer. As for software--I've got nothing more than an eprom reader for
these at this point...if you think GM is tough, you should read
these...basic undone territory. I'll help ya all I can...
