If the TI and Experience of a driver is low, it makes finding the ideal value even more important because of the time you can save.įind out the happy zone for your driver using the following formula: Since speed for gearbox of 150 will be better than that for 125 or 175, you will be faster if you find the exact value (150) instead of using just any value your driver is happy with. So, suppose the ideal setting of a gearbox is 150, and the driver has a happy zone of 50, this means that the driver will be happy for all the values between 125 and 175 for the gearbox. This range changes according to some factors, about which I will discuss later on. The term 'happy zone' or 'happy range' is used to refer to the range over with the driver is happy with the setup. This is because a driver is happy over a big range of setups. However, this does not mean that the setup you have achieved is the ideal setup. He might even say that he is satisfied with the setup. When you setup a car, a driver will, at some point not comment on a particular part. One of the basic things you must understand before learning how to setup a car is the 'Driver Happy Zone' A perfect setup can drastically improve lap timings, and it doesn't cost anything at all. One of the most important things a rookie should know is to calculate his setup properly.
