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.

Release date: 2018-01-26

 

Note: a lot of new settings on the Nitrous system has been added or modified, make sure to check your settings after the firmware update! <-- CRITICAL and MUST BE CHECKED!!!!

Downgrading note: Downgrading from a version 1.109 or above, to version 1.108 or below will corrupt the tune in the ECU. This is because 1.108 does not support the dynamic 4D tables that were added in 1.109. If you still want to do this downgrade, you need to have a tune-file saved from the old version and reload it after after the firmware downgrade.

 

Surface 3D will only work in the first dimension even if an 4D axis is activated, we are working on the Surface 3D update to reflect the 4D changes.
