Electronic (ECU) and Mechanical Engineering

We have an in-house Dyno which we use to tune each bike from start to finish, no duplicate map is used, as a map/tune is custom to each bike built. Using previous experience gained at the drag strip on various bikes which competed in the National Series where Jan Els won the SS class, we tune each and every bike to its full potential. The manufacturer loads the same file on each and every ECU attached to a bike which is fine for the guys that just ride their bikes casually, but if you want the full potential released it needs a custom map according to the pipe and air filter fitted and/or performance modifications done to the engine. ECU flashing using Woolich Racing Tuned Products enables full access to the ECU to control a lot more than just the fuelling of the bike. Each bike receives our personal attention when any work is performed on a bike. We pride ourselves in our high standard of quality and workmanship.
