    Personally I just had madtuner.com socket a couple PCMs for me. Unfortunately they don't appear to offer that service anymore.

    I'm a little late to the party, but I agree. The slight difference in speed will only result in one blower providing slightly more air than the other. The PSI will be even since they're plumbed...

    This would be for a 96-97 PCM, but there was a MAF adder table referenced to TPS that I found worked as an acceleration pump. Using this table, if I recall correctly, I was adding up to 5 to 10...

    I don't think you guys are following the problem. I've got detents for 1st, 2nd, 3rd and 4th. The problem is that while the shifter is in 4th gear, the torque converter doesn't lock when the...

    I've got a '97 Camaro PCM in my truck that is handling the engine and transmission control. I've been banging my head over a little issue that I can't tell if it is intentional or a fault. When the...

    I managed to squeeze the opti trigger wheel and sensor into a TPI distributor. Ultimately I cut the center out of the opti-spark to yield the bearing carrier and sensor mount. I shaved the top of the...

    The intake backfiring and loss of power sounds like the engine is running lean (either due to the PCM or a lack of fuel pressure). My truck has had a similar behavior when the O2 sensors were...

    I am. I do have a OBDI PCM as well, but I've been sticking with the OBDII since I already have cash and tools invested in it. That said, it looks like a lot more development has been made with the...

    Here's a brain teaser for some of you guys. I have a fuel injection conversion on my 85 C-10 that is using a 96-97 LT1 PCM with a 350HO crate engine and TPI intake. It has long tube headers with the...
