I bolted a rimmer supercharger to my 02 Tj 4.0l and I'm trying to wire in a perfect power smt6 piggyback ecu to control fuel and timing. The problem I'm having is I have no Idea how to wire in for Ignition. Any one who's running an smt6 could probably help with a wiring diagram. O(r if anyone out there knows exactly what type of ignition the 4.0 uses, i.e. missing tooth signal, odd signals,bipolar, unipolar???????? trigger pattern????thanks

Sorry can't Help. Mines OBD1. I suggest you go buy a chiltons book for your jeep and sit down and study up the the emmissions and electrical system of your jeep. Thats what I did when I started my turbo system. Gotta know your system and Chiltons is a great book. Alot of good info

YEAH probably not a bad idea. They recomend using a oscilliscope, but I have no idea where to get one or hot to use the thing.
