I'm a sucker for a turbo vehicle.  I recently
bought an '85 Chrysler Laser XT turbo.
Now, I want to see what makes it tick.

Is there a WWW page out there with in-depth
ECU info?  I removed my ECU last night,
and it looks like there are a couple PROMs
on the main board that probably contain
all the "good stuff" that we're all looking for

In case anyone else is keeping track of
this stuff, my Logic Module sticker reads:

Part No. 5226795 Supplier 7902
Data 02/27/85 15:59:44 2

There are two chips in one corner with
stickers on 'em.  They look like PROMs.
One sticker says "FED" on it, and
the other says "5226795" and
"5226794" on it.

Plus...
I have the Haynes maual for the G-body, and
the wiring diagrams are pretty good, but
there are still some holes left open.
Do you know the function of all six wires
of the diagnostic connector?  How 'bout
all the wires that run between the Power
Module and the Logic Module?

What is the format of the dignostic
data stream?  I'd like to be able to
read it without dropping a ton of
money on a scan tool.

Please don't think of me as just
another "taker"... 
I'm a "giver", too. <grin>

I'm the guy that published the
Turbo P4 doc, and I helped the
author or Promgrammer to get
his application working. Plus, I
frequently visit CSH, HQ... to
take out the trash and clean
the toilets.

Thanks,
~~~~~~
