Rolling road remap near Prescot

Here is what a session at Manchester Dyno Centre looks like in practice. Your car arrives at HNA Facilities on James Nasmyth Way, Eccles, Manchester. It goes onto the 4-Wheel-Drive Bapro dynamometer. Samuel Gunnell runs a baseline power pass to establish exactly where the car sits before any work begins. That number is logged.

He reads the ECU using Kess3 or CMD hardware, depending on the platform and what the job requires. He builds or modifies the calibration, then puts the car back on the rollers. Fuelling, boost pressure, ignition timing and knock events are monitored live throughout every run. The data is visible in real time. If the numbers indicate further refinement is needed, the calibration is adjusted and the car runs again.

The session ends when the data confirms the map is correct for your car, not when an arbitrary time limit is reached. You leave with documented before-and-after power figures. Not an estimate, not a projection, a measured output from your engine, on those rollers, on that day.

ECU calibration, Stage 1 (petrol and diesel): software-only map change via OBD or bench, developed and confirmed on the dyno. No hardware modifications required.

ECU calibration, Stage 2 (petrol and diesel): calibration built for hardware already fitted to the car. Intercooler, induction and exhaust modifications must be in place before the session.

TCU calibration: gearbox and DSG remap. Shift timing, torque limits and clutch engagement recalibrated to complement the engine map.

Rolling road session (power verification only): baseline and comparison dyno runs without ECU changes. Used to establish current output or verify the accuracy of previous work.

Launch control activation: standing-start strategy coded into the ECU for consistent, repeatable launches.

Speed limiter recalibration: available for vans and commercial vehicles where the factory limit restricts operational use.

Overrun and anti-lag (flame tune): ignition timing and fuelling adjusted for controlled overrun behaviour. Enthusiast and track use.

Remote platform tuning: Bootmod3 and MHD for supported BMW and Mini platforms. Stage 2 work on any platform requires supporting hardware to be fitted before the calibration session.
