The auto tune feature off of a wide band voltage is a very cool feature indeed and something I've only seen on much more expensive stand alone engine management systems. I will definitely keep this system in mind if I ever build a race car. Unfortunately I need OBD2 to pass emissions and I'd have to get over the giggle factor of buying a system called Megasquirt
Cant you can just make another engine harness for the MS and keep the original ECU in place for Inspection?
