Why your ECU is safe with us

A remap is only as good as the file, the tools and the care behind it. Here's what comes with every ECU tune.

  • Custom tuning file

    Written for your exact car and engine by Top Gear Tuning. We're a verified dealer.

  • Professional tuning tool

    We read and write your ECU with the Alientech KESS3, a professional-grade programming tool.

  • ECU-protected power

    A mains-powered battery support unit keeps your car's voltage steady while we work on it, so a weak battery can't interrupt the tune.

  • Health check before & after

    We scan for faults and check live engine data before we tune, then again after. You know the car's healthy both times.

  • Lifetime software warranty

    For as long as you own the car, if our tune causes a software issue, we'll fix or reinstall it free.

    Terms & conditions apply.
