MaxxECU - Top of the line engine management system.

MaxxECU is a Swedish based company, developing and producing our own market leading engine management system. Made by professional tuners to be the most powerful, easy to use and flexible engine management system ever made. MaxxECU is designed to give optimal performance on the track and on the street. Built-in fault diagnostics and engine protection as standard.

 

MTune, the modern and flexible PC software is used for all configuration, tuning.

MDash, Android app, displays all engine data to the user. Inputs also possible.
