Features: 1. High useful turbo timer, helps to protect your turbo by cooling down after driving. 2. Improves the combustion efficiency of the engine, helping to reduce fuel consumption. 3. Displays voltage, oxygen content (O2), and air fuel ratio (A/F). 4. Automatic countdown feature with 144 different settings to ensure optimal performance across a wide range of vehicles. 5. Utilizes O2 sensor voltage when calculating countdown time, providing more accurate idle time compared to timers that rely only on vehicle speed and RPM. Specification: The Auto Timer allows the vehicle to idle for a preset amount of time after the ignition key has been removed. In turbocharged vehicles, this helps prevent hot oil from coking in the engine lines. Hard driving can raise engine oil temperature to high levels, and proper cool down is essential for turbo and engine longevity. In naturally aspirated vehicles, the Auto Timer can also be used to warm or cool the interior without requiring the driver to remain inside.
