i've been trying to get some things for my 93 z28, but its kinda hard to get them because somethings that i wanna get for my car will only fit strictly on a 93 camaro and then the others fit any 94-97 but not a 93?? can anyone tell me whats the difference??

 

The 93 uses a MAP sensor and does not use a MAF sensor, and has a 700R4/4L60 auto transmission. The 93 PCM uses removable MEMCAL chips for programming.

The 94-97 useboth the MAP and MAF sensors, and use the 4L60E computer controlled transmission. The 94-97 PCMs, both OBDI and OBDII versions,do not use removable chips.

 

oh... ok... cuz i tried to read the computer cuz it seems to have a problem but they plug only fits 94-97 n not 93's... is that the only diff?? a t56 tranny should fit a 93 right??

 

You need an OBDI connector to read your computer, or you can flash the codes out. The 94&95 are OBDI also, but need a OBDII connector, and the codes cannot be flashed, a scan tool is needed. The transmission should fit.
