MaxxECU Race Engine Management System Specification

Truly intended for competition, the MaxxECU Race engine management system offers unparalleled performance and advanced control of your engine. It supports up to 8 cylinders in sequential ignition, or 12 cylinders with wasted spark. It features Bluetooth connectivity and two extra motor outputs (very useful to control e-throttles on newer engines, for example). This ECU has a built-in 4 bar MAP sensor (intake manifold absolute pressure) directly available on the unit’s housing, and manages up 8 EGT (exhaust gas temperature) and 2 knock sensors. Thanks to the MTune software, you will be able to build complete ignition and fuel maps along with many features: variable timing, boost control, Flex Fuel, traction & launch control, anti-lag, and so on. With its 8 Mb of internal memory and 4 processors (including main ARM Cortex-M3 processor at 120 MHz), the MaxxECU Race engine management system is capable of feats: 1000 Hz data logging, ignition resolution of 0.1°, injection resolution of 0.001 ms, and up to 2000 injection and ignition computing per second.

The MaxxECU Race supports the CAN bus protocol and has 8 high or low impedance injector outputs, 8 ignition outputs, 13 extra outputs (inc. x2 e-throttle), 8 extra analog inputs (0-5V) and 4 extra digital inputs, guaranteeing maximum development possibilities! With a dimension of 155 x 195 x 40 mm, it weighs only 880 g. Do not hesitate to check out all the advanced technical information on the official website of the manufacturer!

Unit, Standard, Premium or H2O?

The Standard version of the MaxxECU Race computer is supplied with a Bluetooth antenna, its universal harness and a USB cable for PC connection, along with its wiring and operating instructions (in English). Choose the Premium package to receive on top : a Bosch LSU 4.2 AFR sensor with it’s wiring and connectors, and a harness extension to fit 8 EGT and 2 knock sensors (sensors sold separately). To finish with, H2O versions are waterproof (IP67 standards) and suitable for offroad and exterior use, while the “unit only” version will be fine you just need an ECU without any accessories.

“Plug & Play” Versions on OEM Engine Harness

MaxxECU offers a range called “Plug-in”, to be connected directly to the vehicle’s original harness. No adaptation required, just plug in and map! If your vehicle is equipped with a mass air flow (MAF), it is possible to remove it and upgrade your electronics to manifold pressure management, thanks to the MAP sensor built-in as standard on the MaxxECU unit. The “Plug-in” MaxxECUs are available in Standard and Extra versions:

• Standard: supplied with the adapter for the original engine harness, its manual and a USB connection cable for the PC interface. For performance and accuracy reasons, MaxxECU units do not work with the original lambda probe and require a wideband sensor (0-5V). If you don’t already have one, prefer the Extra version.
• Extra: a Bosch LSU 4.2 wideband lambda sensor with it’s wiring and connector are added on top.
