ECU REMAPPING

What Is ECU Remapping?

ECU remapping (also called ECU tuning or flashing) is the process of reading your engine’s software, modifying it, and re-uploading a new version (a remap) that’s tailored to your goals.

The tuner alters internal maps such as:

  • Boost pressure targets (turbo engines)

  • Fuel injection timing and quantity

  • Ignition timing (petrol engines)

  • Torque limiter thresholds

  • Throttle sensitivity

STEP 1

Diagnostics and Health Check Scan for fault codes

STEP 2

ECU Identification and File Read

STEP 3

files are always custom written

STEP4

Write the Tuned File Back

STEP 5

Road Test and Verification

POPULAR REMAP TYPES

STAGE 1: REMAP (NO HARDWARE MODS)

  • Ideal for daily drivers

  • Optimises power, throttle, and response

  • Retains emissions compliance

  • Fully reversible

STAGE 2: REMAP (WITH INTAKE/EXHAUST MODS)

  • Requires intercooler, intake, downpipe, or exhaust upgrades

  • Higher power/torque

  • May require clutch or gearbox tuning

ECONOMY REMAP

  • Reduced fuel usage at cruising speeds

  • Lower throttle load

  • Popular for fleets and long-distance drivers
