ok, 2 questions
1. if i pick up a used obd1 computer, can i just install it into my car and then get e-mail tuning for it? or is there more to it than that?

2. i currently have a tuned obd2 computer, can i just sell it to someone with the same mods that i have and they can plug it in and it'll work no problem? does different vin# really mean anything?

thanks for any input.

 

You can't just get an OBDI PCM and plug it in. You will also need to swap your knock sensor (not the one in the PCM - that's the knock module) with an OBDI (94-95) one. Then you can get tuning for it if you want.

Your OBDII will work on someone else's car with the same mods and transmission type. It will also work in a 97.

VIN is used for reference only and does not affect driveability. It does have to match the car's VIN if the other person needs to pass scan emissions.

 

ok, so all that i'd need is an obd1 pcm and an obd1 knock "sensor"(goes underneath on the block, if i'm correct??) and then i can get tuning and that's it, ready to go?

 

Yes.

The knock sensor is on the passenger side of the block. It has one wire coming out of it.

 

perfect. thanks Ion.
oh, one more thing, LT4 knock module; do i still need it? or is obd1 different in that matter, and/or will the tune do the same job?
