If I rev hard when accelerating I can get to over 9000 rpm in the first four gears. In 5th I appear to be limited to 7500. The practical result of this is it becomes very difficult to overtake the more senile members of the Middle Lane Owners Club when your max is about 80mph. The ECU does not have an inbuilt 7500 limit so there must be a sensor telling it I am in 5th. Does anyone know where this sensor is located so that I might disconnect it. This should then give me a top speed in the nineties.
