MPI Conversion - PCM & Circuits Needed?
Doing the MPI Conversion using FI from an 1995 Cherokee. Have essentially most everything needed from the 95. Have schematics for the donor-95 cherokee and recepient-85 CJ7. Have reviewed the sites on hooking up the Chrysler MPI and note some questionable differences. The 95 PCM appears to link data a brake sensor, gear sensor, etc in controlling the throttle body and fuel. I have not seen where these sensors are used in the Aftermarket MPI kits.
Can these circuits or sensors be not used and the PCM will adapt - using data from other sensors (temp, air, O2, etc)?
What circuits actually need to be used (pins) to hook up the PCM?
Has anyone developed a schematic for hooking up FI from donor vehicles (95)?
Appreciate your comments - looking forward to moving on this project soon. The Grape CJ tells me it's anxious for a brain transplant!
