Car remapping Rochdale

Here is what a session at Manchester Dyno Centre looks like in practice.

Your car arrives at the facility on James Nasmyth Way, Eccles, Manchester. It goes straight onto the 4-Wheel-Drive Bapro dynamometer. Samuel Gunnell runs a baseline power pass to establish where the car currently sits, fuelling output, boost pressure, ignition timing, and any knock events are all visible in real time before any work has been done.

He reads the ECU via Kess3 or CMD hardware, depending on the platform and what the job requires. The calibration is built or modified on the day, specific to your car's data from that baseline run. The car goes back on the rollers. Every run is monitored live, boost response, fuelling under load, timing behaviour across the rev range. If the data shows a refinement is needed, the calibration is adjusted and the car runs again. The session ends when the data confirms the work is right, not before.

You leave with documented before-and-after power figures: what the car made before Samuel touched it, and what it makes now. That is the process on every job, regardless of vehicle or service type.

ECU calibration, Stage 1 (petrol and diesel): software-only remap developed on the dyno. No hardware changes required. Fuelling, boost, and ignition timing adjusted to the car's actual data.

ECU calibration, Stage 2: full calibration matched to fitted hardware modifications (intercooler, filter, exhaust). Requires supporting hardware to already be fitted before the session. Results confirmed on the rollers.

TCU calibration (DSG and traditional gearboxes): transmission control unit tuning to adjust shift behaviour, shift points, and torque limiters. Carried out alongside ECU calibration where the two need to match.

Rolling road session (power verification only): baseline or verification run without calibration work. Documents current output. Suitable as a standalone check or pre/post reference.

Launch control activation: RPM-based launch control coded and mapped to the platform. Consistent standing start behaviour.

Speed limiter recalibration: available for vans and commercial vehicles where the factory limit is operationally restrictive.

Overrun and anti-lag (flame tune): controlled overrun calibration producing audible character on the overrun. Enthusiast use. Applied as a calibration, not a switch.

Remote platform tuning via Bootmod3 (BM3) and MHD: BMW and Mini platform tuning delivered remotely. Calibration built by Samuel Gunnell, no in-person attendance required.
