No matter what type of racing you’re into, drag racing, land speed racing, autocross, road course, drifting, rally, you name it-- we’ve got your engine management system (a.k.a., standalone ECU) needs covered! Our ECUs also offer engine safeties, allowing you to ensure you protect your engine if that turbo makes a little more boost than you expected, or if your fuel pressure is low, or the air-fuel ratio detected by your wideband o2 sensor is dangerously lean—these safeties can save your engine. Our data logging and analysis tools let you see exactly what is going on and give you the information you need to tune your engine properly and safely, making maximum horsepower and torque.

So you are planning to install a Mustang turbo kit, supercharger, cams, free flowing heads, or any number of other Ford Mustang Performance Auto Parts that will change how your engine breathes requiring a proper tune to get the most out of it, we’ve got your PNP Engine Management needs covered. One-hour install, a solid base map to get you started tuning, and a simple tuning interface makes it easy to tune your engine right.
