After going through the posts here and an e-mail back from HPTuners, it's apparent I cannot log into the PCM for the Sunfire. Thought is was just locked.
Having said that, can anyone tell me how to access it. I only need to change the MAX Speed from 95.
Or can I buy another PCM programmed with the same setup as the original except for the MAX Speed ? If so, where ?
Thanks in Advance.
BTW, it's a Sunfire SE Coupe with Sunroof. 2.2L 5-speed.
Looks like I am going to answer my own question. Just correct me if I'm wrong.
Buy a '97 PCM with the connectors and re-pin from the 3-plug to the 2-plug.
Best way ?
Thats exactly what i did to my ld9 Went from 3 plugs to a 98 2.2 ecu and reping.. the car starts.. the only issue im having is that the car is too rich.. i think is not recognizing the injectors cuz im running the same 450cc from the old ecu that are low impedance.. dont know if i need to adjust the parameters on the 2.2 ecu and lower the cycle or something..
