Have a up-date on this project.
Was able to eliminate crank sensor issues by adjusting the pots and adding 10k resistor inline.
Made it to the dyno and developed a fuel and ignition curve.
1.5 liter motor made 225hp n.a. and 355hp n2o.
Made it to the track and all worked well.
Ms3 n2o control software still needs fine tuning to work well on track. Only item that failed is the SD card
data stopped working.
Am happy w/ my Megasquirt.
