    2000 k2500 old body style.

    Got it and posted up some BIN's XDF's etc on what I can find so far. To the original poster...... have you been able to reflash yet? or have you tried to reflash the tow file to the ECU that starts the truck that you have?

    Yeah that works. Throw a post up and we can start to look at it.

    So I helped write and break the code for the SAAB ECU's into an open source application.....now I need to start looking into the GM ECU's. Can you send me pictures of the ECU opened up? and the chip type on it? Thanks!

    Once the ECU is bricked the only way to recover it is to use the BDM pads on the ecu board in most cases. I would give it a go one more time to see if you can reflash it. Not sure if these trucks are the same as my SAAB (GM) ecu where I have to have 13.5V to flash it and anything less wont allow...

    '90 Suburban 7.4L --- 3 questions on some issues

    Yeah was thinking that the compressor is on the down side of its life......well time to start looking for the replacement. The A/C has started to have intermittent times when it gets a little warm and then cools down but its always loud with a bad vibration.

    turbo kit for my 91 tbi 350?

    I vote megasquirt setup and use T25 from a NG900 (1994-1999) or the old T3 oil only cooled from a 1984-1993 SAAB Classic 900 (both types can be had from ebay rebuilt around $250-350). Check over on http://www.thirdgen.org and they have a few writeups/posts on using megasquirt on the BBC...

In looking at the smoke its bluish/grey and goes away in about 1-2 minutes tops and wreaks of fuel combined with a heavy fuel smell coming from the exhaust when you drive as well. As for the coolant no bubbles or oil in...

    White smoke comeing out muffler....engine?

    Do you get any fuel smell at all when it smokes? My '90 454 Burb does this for about 1-2 minutes when I first start it and is running super rich at startup. So far I think i have tracked mine down to EGR valve but will have to see after i test it. I would personally just rebuild the 350 you...

    What to do first....

    So i have seen allot of mixed things on the TBI spacers and I am on the fence about them. I know that on my SAAB a Phenolic spacer on the manifold works well to help with atomization but that is with an injector per runner so different worlds but should be the same principal. Gotta say that I...

    What to do first....

    So think I have narrowed it down to a TBI spacer and Open Filter to start. I have also been reading on some of the other forums that people have pulled 20-35HP out of just eprom tuning so its time to bust out the Willem programmer and the 27C256 chips and get to tuning.

    What to do first....
