The FATT X timer offers a traditional manual timer and an auto timer. The FATT X auto timer mode is dependent on vehicle ignition pulses. The longer the vehicle operates at a high RPM range, the more time will be added to auto timer mode. The FATT X also offers a temperature display. This will show the ambient temperature surrounding the turbo timer in Celsius. The user can also personalize the background color of the screen. The color can be set to red, orange, or green. The voltage display will show the real time vehicle voltage and will allow the user to check to see if the alternator is working properly. A clock is also built to show current time.
