    Ok, so I did the swap anyway. It was super easy thanks to Lextech's spreadsheet and all the info on here and the interwebs. I used the 2002 Express Van 5.7 with 60E tune from the repository and it...

  3. 99 Suburban 0411 Swap - Simple Question

    I broke this out from my other thread since that was more 80E swap related. We're now on to doing an 411 swap and I want to get this right. Maybe it's PTSD from burning 6 credits doing a 3bar MAP...

    I did look into the 0411 swap, but I just can't justify it. I plan to do zero mods to this thing after the 80E. I'm not going to put money into a Gen I SBC when I could swap in a Gen III/IV and come...

    I don't believe it's a black box PCM. It's a 99 and I think those were 97-earlier.

    Anyway, no dice on the segment swap still. I downloaded a 99 K2500 7.4L tune from the repository. Same OS and...

    I had the same thing happen to me with my truck. Apparently the OS you're probably using doesn't support it. A different OS probably will, but as I was told, you'll need to burn another 6 credits...

    HA! I was just looking over the log again, and I noticed that the B2S1 O2 sensor is averaging 100-200mV the entire time! I think that's the issue that needs to be addressed first. :eek:

    How would I go about flashing the 12212156 into my PCM. Its a 411 PCM if that makes any difference. Is the 12212156 the OS number or the PCM number? :shrug:

    Why do you want the PCM to control boost so bad? That's the way my Typhoon is via a pwm solenoid, and trust me, it's not all that it's cracked up to be.
