    It may be due to the Regal PCM (i.e. the operating system) needing to see the body control module, even if VATS is programmed out of it. I know that was the issue I had with using a 2005 Impala PCM...

    Ha...I sold that project off about 6 months or so ago.

    What I ended up doing was flashing the '03 Grand Prix OS to the '05 Impala PCM since that OS doesn't need to see a BCM. I tried everything I...

    Your best bet is to license the entire '99 Grand Prix 3.8 spread (4 credits). You'll get unlimited tunes for unlimited PCMs for *just* the '99 GP 3800 for same price as two licenses.

    I'm building up an LT1 for my project '94 Z28 (I bought it as a shell so I am foraging for all kinds of parts). I already have a 2002 Chevy Express van pcm and I plan on using it to run the LT1. I...

    Anyone??

    Also, I was wondering if an extra 02 sensor could be added....say, taking an L36 Grand Prix file and adding Sensor 1 Bank 2.
