MaxxECU RACE GEN2

After years of development and testing, the MaxxECU GEN2 RACE is ready to be revealed.
MaxxECU RACE GEN2 uses Superseal 1.0 connectors to simplify the wiring process.


MaxxECU RACE GEN2 has an improved built-in MAP sensor supporting up to 4.5 bar / 65 PSI of boost.
MaxxECU RACE GEN2 features a powder-coated aluminium case with an IP68 water-protection rating.


MaxxECU RACE GEN2 has two USB-C ports* one high-speed 480 Mbit/s port for PC communication and another for tablet communication and charging - both protected by the included rubber covers.
