Woolich racing, direct custom ECU mapping

Have you fitted an aftermarket exhaust or decat?. Would you like improved throttle response?. Does your bike run lumpy on idle? Does the bike suffer from a jerky throttle response?. Would you like improved MPG?.

Engine tuning

If you answer yes to any of the above questions then your motorcycle will benefit from a custom fuelling map.

At JB Motorcycle Services we have the software to custom map your ECU directly on most modern Japanese bikes and  some Triumphs using a combination of Woolich Racing & Tune ECU software.

On models which run primary and secondary injectors (most modern sports bikes) mapping direct to the ECU means that we can control the fueling to all eight injectors unlike using a PC3 or PC5 which only connects to the primary injectors unless you purchase a secondary fueling unit. This gives a cleaner and more responsive fueling map, removes glitches in the throttle response and thus creates more horsepower and torque.

Jerky throttle response

Jerky throttle response is often mis diagnosed as incorrect TPS settings. More commonly it is due to poor fueling setup at small throttle openings.

custom engine map

Even motorcycles with a standard exhaust can benefit from a custom map. No two identical motorcycles will fuel the same due to tolerances within the fuel injector flow rate and engine and the factory installed maps are a generic map and therefore don't take the variance in tolerances into account.

Some exhaust manufacturers will inform you that your fueling wont require any alterations when fitting one of their exhausts, but from experience there are always improvements to be made. If your spending £500 on an exhaust then its worth spending a little more to get your bike fuelling and responding as best it can.

John will spend around 3 to 5 hours on the dyno constantly monitoring the air fuel ratio and remapping each individual throttle position to get the best out of your bike. Downloaded maps are never used!
