    Default 2006 TrailBlazer Tune?

    My buddy has an 06 Trailblazer and he asked if I could shut off his TQ managment and make some adjustments so it isn't so much of a sled, I tune my Duramax but have no idea where to start with this Trailblazer. Any help would be appriected. Thanks

    Turning off TM will help a little, the spark tables need a little massaging too from what Ive seen. My specialty is the 02-05 I6s, havent had the chance to see an 06+ one yet. Post up his stock tune and Ill make a few adjustments for you, then go see how they work out.

    I tried to read it and keeps giving me a error message can't communicate with V2 flash scan I disconnected and re connected a bunch of times and even restarted the computer. Still get the same message.

    Can you post the log text that is displayed...

    You may have to disable the countdown timer display.

    Still having same problems, I checked the bootblocker version it is the newest one, and I updated my EFI software to the latest version. I am stumped. Anyone have any idea?

    So you have V7.5.6 build 99 and V8.1.2 build 75, V2 bootblock 2.06.02 and fw 2.06.16? Hmm, can you follow THIS GUIDE and report the problem to support?

    Just tried reading a 06 P12 and could not , first attempt went to about 60% , gave interrupt error , second attempt got about 20% , interrupt error , third try got about 90% and crashed the Flash application to desktop .
    So it seems the software is not working correctly here either , I did not try slow read , but best I remember that was how I had to do it last time (unchecked fast read) .
    Sent the 3 .blx files to support .
