Stage 2 Remap
Advanced software matched to hardware upgrades such as a sport exhaust or induction kit.
What is Stage 2 Remap?
Stage 2 re-optimises the software for hardware upgrades such as a downpipe/sport exhaust, induction kit or intercooler. Hardware and software are planned together.
When is it needed?
- Wanting more than Stage 1 delivers
- Car already fitted with sports exhaust, downpipe or induction kit
- Feeling of restriction at high revs and exhaust back pressure
Benefits
- Performance beyond Stage 1, matched to the hardware
- Sharper throttle response and stronger top end
- Balanced calibration that respects component life
Stage 2 hardware and measurement planning
The Stage 2 label alone does not define a standard parts list or power gain. Assess the actual hardware, modifications and intended use first.
Document the installed parts
Record intake, exhaust, turbo, cooling and fuel-system changes with part identification. One upgraded component does not increase the capacity of every other component. Consider temperature, fuel quality and drivetrain limits together.
Match calibration to the actual build
Hardware changes can affect airflow, pressure control and load calculations. Match the calibration to installed parts and ECU software; a file from a similarly named vehicle is not a compatibility assessment.
Agree how the result will be checked
Record the baseline, fuel, conditions and measurement method. Review relevant operating data and faults afterwards. Road legality and inspection compliance need separate assessment; removing emissions systems is not an automatic Stage 2 requirement.
