Tuning the Mitsubishi Asx

2017 Mitsubishi ASX

2.2L – di-d – Diesel

Denso RA6  ECU

The Challenge

ECU tuning involves unlocking and adjusting the settings of the Engine Control Unit (ECU) to optimize engine performance. With over 20 years of experience in perfecting the tuning process, Alt Tune is here to discuss the benefits of tuning the Mitsubishi ASX and outline the tuning process.

The Mitsubishi ASX, the smallest vehicle in Mitsubishi’s SUV lineup, shares its platform with the Mitsubishi Lancer and Outlander. While the ASX offers many attractive features for the SUV segment, its lack of power and driving joy are noticeable. This is where custom ECU tuning can make a significant difference. The Mitsubishi ASX comes in many different engine options, however, in this blog post, we are using the 2.2L diesel engine with a Denso ECU as an example.

The Solution

At Alt Tune, we customize every tune to meet your specific needs, considering your vehicle and driving environment. Once we’ve determined the details for the best tune, we use the Alientech KESS3 to safely flash the tune. This approach ensures the best and safest tune for your vehicle. The result is an increase in power and torque, making your Mitsubishi ASX more enjoyable to drive. The throttle response improves, and overtaking becomes safer. You’ll no longer struggle with hills or towing heavy loads.

Diesel engines come with emissions solutions that can cause expensive problems and make the vehicle unreliable. We have developed an emission solution to address these issues, making your Mitsubishi ASX more reliable and helping you save money on mechanic bills.
