GReddy Part # 15500021

The basic function of a turbo timer is to allow the vehicle to idle the engine for a timed period, with the ignition key removed. This allows the engine oil and turbo center cartridge to cool down and prevent internal turbo damage. GReddy Full Auto Timers pack tons of features into one economical, compact unit. In addition to two standard programmable count down presets (P-1, P-2), the GReddy Full Auto Timer also has two auto timer modes (A-L, A-H). The modes estimate the driving RPM according to the vehicles alternator signal and then recommend a count down time. Also new are the stopwatch/lap time and attack modes along with a built in voltmeter and speedometer. Still standard are the optional parking brake and speedo safety hook-ups.
