I just bought a 94 z28 (state trooper car) that had the original engine taken out (due to it being blown) and it had a 96 lt1 put into it. It had some hesitation problems, so I took it to the mechanic. He said that the computer was having some problems matching up 100% with the engine and he's working on calling a technical guy for help.

Has anyone swapped a 96 lt1 into a 94 body or something similar? What needs to be done regarding the PCM/computer/etc? Or is it something else that needs to be changed?

Thanks for any help.

 

Was the PCM changed with the engine? I know 94 is OBDI and 96 is OBDII. I know they look at things a little differently but other than that I'm not sure. Could be the problem though.

 

Nope, the PCM was not changed. Should it be updated to OBDII?

 

I'm not sure what all the differences are regarding the engine aand sensors. Maybe somebody else can chime in and help out. I just know that they are different. I also know that there are a couple of websites that do conversions. Most do an OBDII to OBDI conversion as it seems to be easier to mod the car.
