What company, or product, can reprogram my 1998 3.8L ECU to run stand alone and disable PATS? I want the bare minimum to run the engine in closed loop. So far the engine has had the PVC bypass and EGR delete. Also, the bottom end is 4.2L with 1998 single port heads. I've asked around and no one can lead me to a solution for the PATS problem. I'm not putting this engine in for all out power. It's just an upgrade from the blown up 4 cylinder. I happen to get the engine cheap when a kid decided to go V8 after building the Wee6. I also have the 4r70w transmission that was with the original 3.8L.
