MaxxECU Units

MaxxECU units are standalone engine management systems for project-car builds, with kit options to suit different wiring requirements. Choose from the Mini, Street, Sport, Race, Race H2O, Pro and GEN2 Race, alongside the MaxxECU PDM20 power distribution module. Start by matching the ECU to your engine configuration and required control functions. The Mini supports up to four sequential cylinders, while Street supports up to six and Race and Race H2O support up to eight; wasted-spark capacities are also listed for these models. Product variations include unit-only, connector, basic or standard kits, plus packages with LSU 4.2 or LSU 4.9 wideband lambda sensors. GEN2 Race options use LSU 5.2 sensors, including a dual-sensor kit. ASD Tuning is a UK dealer whose team wires and tunes MaxxECU systems daily.
