Fig 6 shows readings from four of the three main areas of the engine that affect tuning, Throttle Position, RPM, and Lambda. From analysing the data the main fuel table was adjusted using the throttle position and rpm data to move the lambda value as close to 1.00 as possible. After the main fuel table was adjusted the dyno run was repeated and the data analysed again. This process was repeated until the lambda value was as close to 1.00 as possible across all rpm and throttle position areas. The final result was a 2003 GSX- R 600 engine with a 20mm restricted air intake producing 78 bhp.
