1990 pontiac sunbird garbage data
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?

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.
