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?
