Mast Engine Management Systems

Mast Motorsports M-90 and M-120 Engine Management Systems are a great way to start your LS Swap.  

Our Gen IV M-90 DBW Engine Control Package is designed to be a budget friendly solution for GM Gen IV applications that utilize drive by wire throttles. It is the most affordable solution available to get a LS3, LS2, L92,  L99, L76, LY6 pullout or crate engine up and running in any application.   All calibration is developed in house on our 2,000HP Super flow NSCR dyno test cell and and our 1,800HP Superflow eddy current chassis test cell.
