wheelman Posted May 2, 2006 Share Posted May 2, 2006 Glad to hear it's running better, I'll have to go check out that video. I don't have any videos of mine yet but have post a couple sound clips. I got my LT1 from a 1995 9C1 Caprice as well. I didn't use the 4L60E as it was toast and I wanted a manual tranny anyway. As far As I remember the only difference between a 9C1 PCM and the consumer version is the speed limiter was removed. At 105 MPH the consumer PCM will shift the tranny into 3rd to prevent the car from accelerating any more. I thought the VATS was absent also but mine acted like the VATS was there, had to program it out to get it to run more than a couple seconds. I changed my MAF to a 3.5 inch and loaded a Camaro setup into the PCM as a starting point. It seems to run a little rich but I'll get that tuned out. Might be because I've also blocked off the EGR stuff but I don't think so, it's only active at idle. Wheelman Quote Link to comment Share on other sites More sharing options...
