Looking for prom #'s
Hey guys, I'm in need of a list of prom #'s--all the stock GM #'s.
I had a site book marked--but it's no longer available.
Also--can someone tell me what chip this is?-ACXS 1088.
I need a stock chip for an 89 350 tpi w/3.27's and an auto.
Thanks alot.

This is the website I have, but have found others.
http://www.cruzers.com/~ludis/p4xref.html
This is probably a more comprehensive site

Thanks! That's what I'm looking for.
Question now--I think this is my prom # but it lists it for other applications--like a 4cyl. Is this true?
I have a stock prom from my 86 305 tpi, auto w/3.27's--my 89 has the same thing except for the 9th inj(86), vats and it's a 350.
Think I could use the stock 86 prom for my 89 application? Or do I have to get an 89 specific chip?
This is what it says:
1227165
16198259
Schematic
Application: 1986 2.0 L4 TBI “P” LQ5 w/ MT
1986-89 5.0 V8 TPI “F” LB9
1986-89 5.7 V8 TPI “8” L98
1987-91 truck 2.5 L4 TBI “E” LN8
1991 truck 2.5 L4 TBI “A” L38
MEMCAL IDs: “P”: CRY, CRZ, …
“F”: AUM, ACXT, AKFM, AKFR, …
“8”: BUA, AANK, AANL, APYP, APYU, AUJM, …
“E”: ADHF, AMJW, ASWY, AXAA, …
“A”: AUXH, …
EPROM type: 27C128
Thanks for the help.

I'm trying to find out if my chip from the 86 tpi has the cold start injector, it's a 305 and has no vats-would start my 89-that's a 350, no cold start injector and has vats. I'm still trying to chase down my no start problem. I think it might be the vats-but I'm not sure. I have fuel pressure--and spark was present for a few cranks then just dissappeared! I haven't had a chance to put another coil to test it yet(has an Accel in it). I know if the vats doesn't see the right resistance it'll cut something out so the car won't start--thought it was the fuel tho.
So...would the 86 chip work in my 89? Just to make it start--not run-just start it up?

Guess it isn't the prom--I tried putting it in but it still won't start!
Gonna try tto replace the coil-it's an Accel.
Anyone have trouble w/the remote Accel coil? This will be my 2nd one(if it's bad)
