Thanks for adding me to the Forum. I am in the middle of an engine swap in my 1992 Jeep YJ from a 2.5L to a 4.3L V6 (CPI) from a 1993 S10 Blazer. I have also installed an NV3500 standard transmission. I'm using the original wire harness from the S10 so thats been loads of fun mating it to the Jeep. I'm sure I will have lots of questions as I get started data logging and tuning next week.
