'96 Pontiac Sunfire PCM - Cannot Read w/ HPT
Thursday, January 02, 2020 7:43 AM
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 ?
