The Syvecs Toyota Yaris GR ECU kit brings a new level of engine management control to the Toyota Yaris GR.

Since the launch of the Toyota GR Yaris there has been A bottle-neck to power. The inability to unlock the stock Toyota ECU to any form of Remapping has only allowed a real power level of just over 310bhp. Yes there are many plug in tuning boxes that trick various sensors into adding power but this New Syvecs Direct Plug In ECU is the real deal with over 10,000 different programmable tables that allow total control over all the engine functions of the Yaris GR

After many months of testing with Toyota Europe Syvecs are ready to launch customer versions of the tried and tested Toyota Yaris GR Syvecs ECU Kit.

What do we supply and how does it work ?
1. We can offer this standalone ECU supplied with a base Syvecs map which will get the car running and drivable, however the map will need datalogging and adjusting before the car is driven normally, at speed.
