Toyota GR Yaris ECU Remap with Ecutek – 283bhp to 329bhp Power Boost!

Toyota GR Yaris ECU Remapped with Ecutek – Massive Gains Unleashed

Another Toyota GR Yaris has rolled into the Garage Whifbitz workshop—this time for a full custom ECU remap using Ecutek software, and the results were impressive as always.

Modifications on Arrival

The GR Yaris came to us already fitted with a list of performance-enhancing upgrades:

✔ Scorpion GPF Delete Pipe
✔ Pumaspeed Exhaust System
✔ Japspeed Front-Mount Intercooler
✔ Eventuri Carbon Fibre Intake Kit

These bolt-ons set the stage for a strong performance remap, allowing the car to breathe better and run cooler under load.

Power Figures – Before & After

We ran the car on our dyno and achieved the following results:

✔ Before Remap: 283bhp
✔ After Ecutek Remap: 329bhp

That’s an impressive 46bhp gain, making the car far more responsive with stronger mid-range torque and improved overall driveability.
