it is part of an ads definition file. Seems to be in every one. Just curious.

The next step for me will be to pull the ecm out of the car and see exactly what I have. It is winter and the car is outside so it might be a while. I was looking at the headers on the files I have...

from what I have seen studying the schematics the ecm is a 16 bit computer chip with the program and data tables stored in a 2732 eprom. Of course the prom has to match the application exactly, the...

OK, thanks. Looks like I need to learn a few things before I ask any more questions. I have a background working on aircraft computer control systems but this is somewhat different.

The ECM i have in there right now is a 1227748. I tried a couple of definition files including $135 which Bob Saar gave me. The car runs fine with that ecm but I just can't read any reliable data...

why isn't anyone responding to my post? I have supplied all of the information asked for.

why is no one helping me with my question? I have supplied all the information asked for.

[QUOTE=1project2many;55985]Yes, we can answer the question. Please provide the BCC and ecm number so we can confirm that you are using the correct files. Pontiac didn't equip their cars with 2.2l...

Can anyone answer the question I posed about the data coming back being garbage? I am using the definition file that Bob Saar gave me for that car and the data I get jumps around all over the place....

what do those terms mean ?

Ok, i thought maybe you had passed

I am sure what those terms mean?

I have a 1990 pontiac sunbird with the 2.2 liter engine. I used both $70.ads and $135.ads, converted them both to adx and attempted to use tunerpro. All I got was garbage data jumping wildly all...

I am looking for a 1227748 ads or adx file that will work with a 1990 pontiac sunbird with a 2.0 liter tbi ohc l4 engine 4 cylinder. I have tried all of the definition files you have for that chip...
