JMTC Performance ECU Tuning
Want more power and torque, than let the experts at JMTC optimize your ECU. We have had over 20 years experience making power on not only Mini Coopers but Fiat and Peugeot to name only a few. With our flash we remap the boost pressures, air fuel ratios, ignition timing, throttle response and the rev limiter as well as many other parameters. We also keep them in safe limits to keep your engine running strong. So If you looking for a safe tune that will make the most power and torque possible than this is the tune for you. Let our expert show you the power with minimal upgrades or really amp it up with custom tuning to match your specific upgrades.
