PCM to OBD II & Diablo Sport Problem
I just installed a new RIPP
MODS Supercharger in my 2006 Jeep Wrangler 4.6L w/Stage II Stroker Kit. Everything went smooth up until the Diablo Sport Intune programmer. I'm not able to make it connect to my PCM! I went to a speed shop here in Vegas to have it programmed and setup on their Dynotuner. He wasn't able to get the PCM to communicate with the Diablo Tuner either. He speculated that there was something wrong with the PCM or the wiring harness. The wiring harness, new from the dealer, which I installed. Anyway, he suggested I take it to the dealership to have it checked out. So the was able to program the module with the stock program. No problem. Took it back to the Dyno shop and still no luck, not only with using my Diablo tuner, but one of his own, and even a Trinity tuner. But what is weird is how am I able to clear trouble codes with my Innova Scan Tool, but not with the tuner? I was even able to connect to another '06's PCM with it. I'm thinking my PCM 's write circuit or something along that line is bad. I checked my grounds to the block, which someone suggested, and all is tight, cleaned with sandpaper, and good. I've checked my connections to the PCM and all is good. No bent pins. I'm having a new PCM installed tomorrow but I don't think it's going to fix my problem.
