ECU Remapping Frequently Asked Questions
Will remapping damage my car's engine?
No. Our dyno-developed calibrations keep all vital parameters within safe tolerances, and we always run a full health check before and after tuning.
Is ECU remapping legal in Northern Ireland and will it affect my MOT?
Yes—remapping is legal provided your car still meets the manufacturer’s emissions limits. Our calibrations pass the standard MOT smoke and OBD checks, so you remain fully road-legal.
How long does an ECU remap take at your Northern Ireland workshop?
Most Stage 1 remaps are completed in 60–90 minutes, including the initial diagnostic scan and a post-remap test drive.
How much extra power or fuel economy can I expect?
Gains vary by engine, but customers typically see 20–35 % more bhp and up to 10–15 % better MPG—your exact figures are confirmed when we quote your registration.
Can you revert the remap if I sell the car or need to claim under warranty?
Absolutely. We back up your original file free of charge and can restore it within minutes if you ever need the vehicle returned to stock.
