4t is vref from the alt, if i'd realized that I would have use it for the alt circuit.
On another note, on the MSMs there is a 2nd IAT which is on pin 4R, (I'm going to tap into those wires and run a GM open IAT).
Btw, got the car running pretty well, used the diyautotune 99 map. Stock msm ecu is so crappy, once I get the ebc wired up this car will be completely transformed, and even more awesome in bsp :-)
I would also like to add that setting the zero crossing pots is a bit of a pita. The suggested adjustment didn't work, got the old dmm out and set them and sync is great now.

So.... as it turns out, e85 with rx8 yellows on a mazdaspeed are definitely on the edge if you want to max out the turbo. I was seeing around 100% duty at 11.8:1 AFR (gas scale) at 6k rpm at 170kpa with 85 degree mat temps. GM Mat installed in begi intake elbow (right before TB basically).... So for blytheville it'll be ok cause its gonna be 900 thousand degress out there, but if he wants to drive it hard at night AFR safety system might rain on the fun.... Until they put some bigger injectors in it anyway.
