VW T-Roc R remap
Every T-Roc R is calibrated on our 4WD Bapro dyno, the only way to load 4Motion properly on a car this capable of putting its power down. Call 0161 302 5117 to discuss your car.
Why the 4WD dyno matters for the T-Roc R
The T-Roc R's 4Motion system shifts drive between axles under load rather than sitting in a fixed split, and a two-roller dyno cannot load that properly. Holding only one axle on rollers either leaves the system partially unloaded or forces it into an operating mode it never uses on the road, and the power figure that comes out of a pull like that is not one worth trusting. Our 4WD Bapro dynamometer loads all four wheels simultaneously, the same rig used for the Golf R and other Haldex-based 4Motion cars in this workshop, so the T-Roc R's 4Motion system operates exactly as it does on the road throughout the baseline pull, the calibration and the verification runs.
How we map the T-Roc R
A baseline pull on the 4WD Bapro establishes exactly what your T-Roc R is producing before anything changes. Samuel Gunnell reads the ECU and develops the calibration from that baseline data, working within the EA888 evo4's standard hardware for Stage 1. Once the map is applied, verification pulls on the same rollers, back to back with the baseline, confirm the result rather than assume it.
Beyond the Stage 1 map developed on the dyno
Stage 1 is the primary calibration on the T-Roc R's EA888 evo4, software only and developed on the dyno. Stage 2 is available once supporting hardware, typically an upgraded intercooler and downpipe, is fitted. A DSG remap alongside the engine map adjusts shift speed, shift points and launch control calibration, best done in the same visit. A standalone rolling road session is available without a remap attached. We do not offer speed limiter removal or a flame tune on the T-Roc R.
Stage 1 vs Stage 2
Stage 1 on the EA888 evo4 is software only, working within the standard turbocharger, intercooler and exhaust to unlock the margin Volkswagen leaves in the factory calibration. Stage 2 requires supporting hardware, an upgraded intercooler and downpipe are the usual starting points, before a more aggressive calibration is developed to suit the increased airflow. We will advise on whether Stage 2 makes sense for your car and how you use it, and we will not push it where Stage 1 already delivers what you are after.
