Stage 1 ECU MAP GR YARIS

String Theory Garage Stage 1 ECU tune for GR Yaris.
Developed by ourselves over countless hours on the dyno and tested in real world conditions. Our bespoke ECU tune maintains stock driveability, reliability and refinement yet delivers 316HP and 436NM.

The spread of torque is much improved over the standard car, giving a greater level of flexbility and driveability. Power is now available at a wider rev range, whilst also eager to rev past 6000rpm.

Flashing of the ECU is done by ourselves at our base in Stratford-upon-Avon. We also offer included in the price, the option to return to standard for any warranty or service work at Toyota. This re-flash option is unlimited.

All of our development was carried out on a 4wd mechanically linked Dyno and thoroughly tested by ourselves  prior to release.
