I am doing a heads and solid roller set up this winter and want to be able to dyno tune the car. I have a 93 and would like to get a 94 pcm and wirring harness. Can i have the maf disabble and just run it like a 93? Will i have to switch over any sensors? Will i have problems with the 94 harness going in the 93? is there anyone in chicago land that can dyno tune my car?

You will need either new sensors on teh TB or a new TB for the 94.
You will also need new O2's, not sure about teh opti, but I can check since I will be running a 95 LT1 with 93 Electronics.
Coil may be diiferent too, but I am running an MSD with a Blaster coil so that won't affect me.
I have some TB parts that I may swap with you, or the entire TB with all sensors. I've also got a pair of slightly used O2's that I bought, but won't be using.

You can run it without the MAF. There is a setting in Tunercat to disable the MAF on the 94-95 PCM.

 

Just giving ya'll a heads up, check out www.speeddensity.org for the model year 1993 specific info. We are just starting up, so its kinda slow, but there are alot of 93 experts on there willing to offer advice/info. THNX Dave

 

i already converted to the 4 wire heated o2 sensors so i should be good on that.
