I have a 400 Pontiac with IR intake, I'm setting it up with a 730/AUJP
for now. I was just wondering if it would be possible to write a
completely new program though. I can see needing an open loop idle,
removing the emissions controls, adding a PWM controlled N2O setup,
dataloging.... and just basically playing with features. It's not really
about what's easiest. It's all about having fun, and unwinding.
