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 over the place. I tried with and without the 10k resistor and no luck. My setup works fine with my 1994 s10. I am using a usb to ALDL from my laptop. I attempted to contact Robert Saar but he has not answered my emails. Can anybody point me in the right direction?
2.2? It should have a 2.0L. IIRC in 1990 they only had the OHC version.
What's the ECM service number and the BCC?
The man who says something is impossible, is usually interrupted by the man doing it.
I've still got your 5 emails sitting in my inbox, but I've been about 2 months behind at work for about the past 3 months... I haven't been able to undertake anything that requires more than 5 minutes of attention for that time.

Ok, i thought maybe you had passed
I am sure what those terms mean?
what do those terms mean ?
ECM = The engine computer.
BCC = three or four letter code from the chip in the ecm.
OHC = OverHead Cam
IIRC = If I Remember Correctly
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. Is it the serial interface not syncing up with the ECM correctly? I tried it with the 10K resistor an it made no difference. If none of this works is there a scan tool that would work with this car? I need to troubleshoot it.Originally Posted by 1project2many
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 engines in the US in 1990 so we want to start from the beginning.
