MPI Conversion
i hope I have the right person for the MPI conversion question i still have a hard time navigating this site. It is relatively simple and no in tank pump needed. I prefer the return line fuel system. aftermarket holley frame mount pump. plumb the return line into the fuel filler neck. i used an 94 ram truck harness it mounted the pcm where the right inner fender is. if some one wants to know in great detail i am willing to share. 600 for the 93 jeep grand cherokee rollover with 155k (powertrain) 100 for the ram truck harness (pick n pull) 100ish for the holley pump 50 dollars for a 94 360 pcm which worked on the 93 318. excellent power add and fuel economy 35s 4:10 gears 18 mpg highway @ 2000rpm. It is all wiring patients and plumbing and the ability to read and understand a wiring diagram. most fun mod i ever did wiring took 20 hours but it started first time and i ohm checked every wire and ground in the whole harness and removed every unneeded wire to eliminate confusion.
