CJS Racing - Dyno Tuning

If your bike has extensive modifications, remapping is recommended as the full potential of the engine will never be realised. A bad air fuel ratio can melt pistons in a short amount of time and can diminish power delivery. Please bear in mind even stock production motorcycles suffer from bad fuelling that causes flat spots and stuttering at low speeds. All this can be eliminated with a dyno set up.

Our equipment comprises the latest Dyna Pro load-controlled dyno running 4 lab quality Lambda sensors that samples the engines cylinders simultaneously. We do not waste your time and money making basic average maps with the air fuel ratio's measured at the tailpipe like most other firms. This leads to inconsistent and incorrect Air Fuel Ratio readings doing more harm than good. The V twin needs to be treated as two individual engines or correct fuelling, power, torque and drivability will never be optimal.

Going direct into the original ECU gives you twice the amount of throttle position and rpm set points than any other unit on the market meaning the end result is smoother performance.

There are also fuel and spark maps for all cylinders combined with hundreds of other special functions like rev limits, fly by wire adjustment, secret map switches, lambda deactivation and target air fuel ratio maps.

Ride in Ride out prices vary depending on whether we remap the main fuel map or for serious enthusiasts optimise the entire operating system including offsets and spark maps for serious performance.
