About remapping
The Toyota GR Yaris accounts for 16 files in our catalogue, entirely the 1.6T three-cylinder turbocharged petrol. It is a homologation-derived hot hatch with all-wheel drive, built for rallying rather than adapted from a shopping car.
Stage 1 makes up 15 files — a very clean profile — with one Stage 2. The ECUs are Denso references: R7F7, R7F701216 and RF7. It is a recent, well-defined group with no ambiguity in its mechanical package.

How much does the 1.6T take?
It is a turbocharged three-cylinder built for competition, with genuine headroom. Stage 1 works with standard hardware.
Does it affect the all-wheel-drive system?
No. The work is done on the engine ECU and does not alter the operation of the drivetrain.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
