I still haven't figured out why it wouldn't fire on the original DSP5 tune.. Found a couple more wires in the lbz chassis harness side that are different from an lmm, but nothing critical. We ran a lmm ecm on Marks dyno with lbz harness and only MAF was missing. I swapped those on this harness.

At first I thought it was because I forgot to set relearn timers to 0 under VATS. But fixed that, still no love. Sent him a non-DSP tune with same VATS parameters and it fires right up..

Only thing I can think is that CAX file mod we did for map scaling doesn't like being upgrade to a DSP os. I'm gotta run it on my bench setup next week and figure this one out.
