    16196388 BNJX ECM / PCM

    I have a ECM / PCM from a 1996 GMC B7 school bus with a 366 big block engine. I will sell it for shipping plus 20 bucks for my time / trouble. Located east of Austin, Texas.

    I don't need it...

    You were exactly right, I had a crappy xdf. I got the advanced xdf now. Much better. I found the open loop afr vs temperature vs vacuum table and it seems to be exactly what I needed. Thank you so...

    I must be using a BJDR based bin then. I also tried BNKN at one time I think.
  4. Cold Engine runs Too Rich, which tables to adjust?

    I'm trying to find out what tables or scalars affect AFR when the engine is cold.

    I have PCM 16197427 with bin BJYL and mask OE ( I think I got all those words right). It runs rich when cold,...

    I'm glad you brought this back up. Just this week I was trying to find out the same thing. On my last bin I used PE min and Max temperate settings and I still got PE while driving. I just changed it...
  8. Acceleration Enrichment, disable for datalogging?

    Is it a good idea to disable AE for datalogging for tuning the VE tables?

    I am thinking yes, because when I hit the throttle my BLM is at 128 for that instant while AE is enabled, and I think this...

    I do not understand this either, and I would very much like to know.

    You have to adjust the bin to fit your vehicle. You have to do dataloging. You've got some reading to do. :)

    It sounds like you are missing several pieces of hardware. The ALDL cable will only allow for data and resetting trouble codes.

    I fixed it today, and I'm feeling a bit sheepish.12234
    It was a fuse.
    I have few excuses, except that I never questioned a fuse because I thought it wouldn't start or fire the injectors at all if...

    Can someone tell me what a normal injector base pulse width is for idle on a similar engine? From my logs it appears that it will idle with the bpw above 2 but dies from the lean condition when it...

    So here's where I'm at. Fuel supply is fine, judging by the fuel pressure gauge and the fact that by teasing the MAp tube off and on it can run indefinitely.

    It runs with the MAP tube being...

    Here is what it looks like with a noid light on the injector connector. The part where i fiddled with the tube was because I've had a few beers and I thought I needed to be clear that the tube was...

    I can keep it running on starting fluid ;)

    First thing I did was get a fuel pressure gauge. Fuel pressure and supply is good.

    I guess I should have said that it uses the OE xdf.

    Here is a log I took today. I alternated between starting it with the MAP hose connected and disconnected. You can see which is which because...
