Toyota GR Yaris remap
Dyno-verified Stage 1 gains on the G16E-GTS, measured through GR-Four the way it actually sends drive to the road, not estimated on a two-roller rig. Call 0161 302 5117 to discuss your car.
GR Yaris power figures
| Stage | BHP | Torque | Notes | |–-|–-|–-|–-| | Stock | 257 bhp | 360 Nm | G16E-GTS 1.6 turbo, GR-Four AWD. Circuit Pack adds a mechanical front and rear Torsen limited-slip differential and suspension changes, not extra power | | Stage 1 | | | Software only, no hardware changes |
These figures are not lifted from a forum thread or a spec sheet extrapolation. What you see above from Stage 1 onward is what your specific car produces on our 4WD Bapro dynamometer, measured through all four wheels the way GR-Four actually delivers drive, not projected from a single driven axle.
What the gain feels like
The G16E-GTS already has a distinctive character in standard form, urgent and eager low down for a three-cylinder engine of this size. A properly developed Stage 1 calibration sharpens that further rather than changing it into something else. Throttle response tightens, the mid-range pulls with more urgency out of tighter corners, and the gap between gears closes because the engine is working with less restriction between shifts. This is not a car that needs a bigger number to feel faster. It needs the existing character amplified, and that is what a calibration built specifically for this engine delivers.
Every service available on the GR Yaris
Stage 1 is the primary service on the G16E-GTS, developed and verified on the dyno rather than applied as a generic file. Stage 2 depends on supporting hardware, typically an upgraded intake and exhaust, before a more aggressive map is appropriate. A standalone rolling road session is available for owners preparing for a track day who want a documented baseline figure. Launch control coding is available where the car is specified with it. We do not offer speed limiter removal or a flame tune on the GR Yaris, neither is relevant to this platform.
Dyno proof for this platform
GR-Four is not a badge, it is the reason the GR Yaris drives the way it does, with drive split and shifted between axles depending on the selected mode. A two-roller dyno cannot load that properly, because holding only one axle on rollers means the system is not operating the way it does on the road. Our 4WD Bapro dynamometer loads all four wheels simultaneously, so GR-Four operates normally throughout the pull. The figures in the table above are what the car produces with the system doing exactly what it does when you drive it, not a compromised version of that.
