Marine & Boat Tuning
ECU remapping for boats and marine diesel engines. Improved throttle response, stronger performance and better fuel efficiency on the water.
What is a marine remap?
Marine engines work hard against constant load, so a marine remap is all about smooth, dependable power and efficiency on the water. We rewrite the software in your engine's control unit (ECU) to sharpen throttle response, deliver stronger, more progressive performance and improve fuel efficiency — making your boat more enjoyable to helm and more economical to run.
Every marine file is genuinely custom-written and tested in-house by our own calibration engineers, and always calibrated to stay within the safe limits of your engine. Whether it's a leisure cruiser, a RIB or a working boat, the aim is reliable performance and better economy you can feel — all backed by our lifetime software warranty.
