I plan on using MegaSquirt on mine. It'll be a steep learning curve, but for the cost and the features it really can't be beat. Plus, I like buying things that need to be assembled vs spending extra money I don't have! IIRC, Megasquirt has an onboard 1.5 BAR map sensor for up to 7 lbs of boost. If you need more, put an external 2 or 3 bar and use the onboard for atmospheric pressure measurements. Remember, the higher BAR sensor the more concentrated (less accurate) the signal. You go from reading 20 psi in 0-5 volts to 40 or 60 in 0-5 volts. One of the reasons a MAF is still desired, more accurate air measurements.
