Stage 2 ECU Tuning
Advanced remap for vehicles with supporting hardware upgrades such as a downpipe, intake or intercooler.
Stage 2 is an advanced remap intended for cars that already carry supporting hardware. It builds on Stage 1 and assumes upgrades such as a sports or decat downpipe, a freer intake, an upgraded intercooler or a less restrictive exhaust are already fitted.
With those parts in place the engine can move more air and clear exhaust gas more easily, so the calibration has more room to work. The ECU maps can then run more aggressive boost, fuelling and timing than a Stage 1 file would allow on standard hardware.
The result is typically around 30-40% more power over stock, with a sharper and stronger mid-range; the exact figures vary by engine and by the hardware fitted. The supporting parts must be installed first, because a Stage 2 map is written on the assumption that they are present.
Every Stage 2 solution is prepared for the specific ECU and remains reversible, with the original file kept on record. It suits owners who want a coherent package where the software and the hardware are matched to each other.

Frequently Asked Questions
What is the difference between Stage 1 and Stage 2?
Stage 2 is calibrated for cars with supporting hardware such as a downpipe, decat, intake or larger intercooler. It uses the extra airflow for more power than Stage 1, which is limited to standard hardware.
Which hardware is required?
At minimum a freer-flowing exhaust (downpipe or decat); an intake and uprated intercooler help. Tell us the exact parts when you upload, because the file is matched to them.
Which file do I need to upload?
A full read of the original ECU file plus a description of the installed hardware. If the car already has a Stage 1 file, send the original stock file as well.
How long does a Stage 2 file take?
Typically 10-45 minutes once a tuner picks up the ticket; combined requests with gearbox or launch control can take a little longer.
Is Stage 2 reversible?
Yes, by flashing the original file back. Remember that hardware such as a decat or downpipe may itself affect road legality and emissions.
How is Stage 2 paid for?
With credits from your account balance. The credit amount depends on the ECU and is shown after analysis, before you confirm.
