My goal is to try and put a TPI system on a pre-86 motor for under a $1000 not including the fuel system if possible. The motor is just a generic rebuilt 350 with a small hydraulic flat tappet cam. Basically a stock 350 along with a turbo 400 transmission. I was fortunate to come by a 85 camaro 305 motor that had been sitting outside for a really long time. Got the whole motor and tpi system. I like the idea of a MAP system better but MAF is fine whichever is the cheaper method. My main problem at this point is finding a ECU/Wiring harness combo that will work and not be overly expensive w/AC control. I will consider no timing control or a stock computer if it would work with my motor either option is better than a carburetor. I am ok with learning how to tune if that needs to be done on megasquirt, stock ECU, etc. I think a MAP wiring harness and MAP stock ECU is my only option.

Note: Also I broke the distributor taking it out of the block and the throttle body does not shut on its own.

If you already found an 85 TPI Camaro than why not just use that factory Thirdgen TPI harness / ECM with a 85 Vett 350 TPI Chip ?

 

I agree, why not use the 85/MAF system??? ..just swap in the appropriate tune, as John says.

 

85 ecm sucks, you can rework the harness to work with the. 1227165 ecm.
