Power Programmer Plus for '95 LT-1
Power Programmer Plus for '95 LT-1 Hello,
I bought a hypertech power programmer plus for my T/A. The manual says that it should work for '94 - '97 LT-1's and LT-4's. When I plug it in, it goes through the self test, then tries to communicate with the computer. That's where it hangs up and doesn't do anything. It's supposed to recognize the vehicle but does not. It simply tries to talk for about 30 seconds and shuts off. Anybody with similar experiences? The guy I bought it from claims that he returned his vehicle to stock before I got it. Even if he didn't, the instructions tell me that the programmer would at least tell me that. It does nothing (except for a self test). I need help...

Well from what I remember it shouldnt be the same programmer for 94-97, 94 was OBDI, 95 was OBDI with OBDII connector (if I recall correctly), and 96 and on was a totally different pcm with a OBDII connector... Feel free to correct me if Im wrong, just what I recall.
You're right 97formy,
The sticker on the back says '96 LT-1. I didn't notice until you said something. Guess I'm screwed on this one. I'll try and sell it and buy the right one. Thanks for your help!

OK so you don't like the hypertech.. I can understand that. because I thought it would do more before I read the manual. The guy I bought it from claims that he used it on a 97 SS and on a 94 impala. But the sticker says "96 Z28, Formula, Trans Am, 5.7L LT-1 Auto/Manual" Its not clear if this thing should at least talk to my chip. by the way.... I did turn the ignition on (without cranking the engine)...
you can also send it back to hypertech and get them to reset it i am not sure of the charge. i use mine with my pcmforless tune, cause i like to change my tire size when i put on ET's so it fixes my speedomiter. i would rather keep mine to save from getting tickets for speeding

Two pcms with proper programming one for each tires size would be MUCH less risky and cheaper. Every time you reflash you are taking a chance.
It is also really easy to run the math and figure out about how much a speedo is off for that little bit of use and just remeber the difference.

My car has an OBDII connector (I know the OBDI connectors are different). Is it possible for me to have the OBDII connector with OBDI compatibility?
