I did a 0411 pcm swap on my 96 vortec Z71, only prob is that the 02 express van doesnt have 4low shift tables. Is there anyway to add this into my tune or am I just stuck spinning tires on steep slopes?

If you have not already registered the VIN with your tuner then i would download a tune for a 4x4 and write it to it.
I have a vortec 5.7l.Originally Posted by Dominatorstang
Only vehicle with that motor and setup on the 0411 PCM is the express van.
no 4 wheel drive. I mean 4 high is fine, shifts great, but 4 low doesnt reach required speed to shift out.
I do believe all 0411 pcms that came WITH 4x4 were 5.3, 6.0 etc..
Someone please correct me if I'm wrong, as it was my understanding that this calibration (01-02 express van 5.7l) was the ONLY one that would work with my 96 model truck.
I think I found a solution......If I wired in the "perf" switch, and used that table for 4 low patterns, then I could actually have "4 LOW" Shifted out
Just have to sacrifice my TOW/HAUL mode.
Anybody? Is this my only option?
