What is ECU Remapping?

ECU remapping, also known as chip tuning, is the process of reprogramming your car’s Engine Control Unit (ECU). The ECU is responsible for controlling key engine parameters such as fuel injection, ignition timing, turbo boost pressure, and throttle response.

Manufacturers often limit the power of a car to meet emissions standards and various global regulations. With a custom ECU remap, we adjust these settings to unlock your car’s full potential safely and reliably.

 Trustindex verifies that the original source of the review is Google. Thank you guys for your professional, dedicated and honest opinion. You made my day by fixing my son's car so he could use it for DoE at very short notice. Max and Kay were brilliant and I would definitely recommend this garage as a organised and trustworthy business. Keep up the good work.

 Trustindex verifies that the original source of the review is Google. I was recommended Onyx to get my diamond-cut alloys refurbished. I am located an hour away but the recommendation was important so decided to leave my car with these guys. First impressions, the team were very polite, friendly (Essan, Ben and the guys that actually did the refurb in the intense heat) The prices were competitive. And the quality of work was super. There was slight miscommunication post the sale (which happens) but I was pleased they resolved this to my satisfaction. One idea I would suggest is advising the customer 'before' the work starts that the TPF valves may need replacing so we have the option to decide whether to do it whilst the wheels are off anyway rather than post refurb to avoid scratching the newly done alloys. Otherwise happy with my overall experience.
