More Power, More Torque, Smoother Acceleration and Better Fuel Economy

Based in Weymouth, we are one of the only remapping companies in the area with a MAHA dyno. We provide custom tuned remaps with before & after print outs.

When a manufacturer develops a new car they have to take into consideration all of the conditions it may be subjected to in all of the regions in which they intend to sell this model. This means instead of just optimising the ECU’s program or ‘map’ to deliver the best performance or the most fuel efficiency they have to make compromises to the map to take into account these potential differing operating conditions. These could include sub-standard fuels, extremes in temperature and altitude, differing emission laws and even the possibility that vehicle may not be serviced on a regular basis and in accordance with the manufacturers recommended instructions.

ECU remapping is taking a read from the ECU’s processing chip of the vehicles standard compromised map and adjusting various parameters within the map such as fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal control amongst others to release the true performance from the engine. It is a completely safe process as it is just giving the engine the performance it should have had in the first place before all the compromises were applied to the original programming. Every engine will have its own unique map and by adjusting this we can fine tune the characteristics of the engine; unleashing more power and in many cases reduce fuel consumption too.



JC Performance are passionate about tuning vehicles correctly. We have heavily invested in this sector and in 2017 installed a MAHA LPS3000 rolling road.

There are so many so called tuners out there. Without a rolling road they pluck figures from the air and more times than not, their tuning is no where near the quoted figures by them. They simply plug your vehicle in and flash a new file onto it.

At JC Performance, we do a full health check on your vehicle, do a full data log of how your vehicle is running while we do a dyne run and then tune your vehicle correctly to this. After tuning, we do exactly the same again and this way we produce before and after graphs to prove the power increase and prove it has been tuned correctly.
