Rev-Shift Timer

Keep your engine Cool and Calm.

REV-Shift Timer does it all for you.

The REV Shift Timer was developed specifically to combat improper engine oil cooling and over-revving. The RST is a full functioning turbo timer with an integrated shift light, plus additional monitoring functions. All these features are built into the same compact size unit as ARK Design's Advanced Boost Controller (ABC) so the REV Shift Timer and ABC perfectly complement each other in any vehicle's interior.

Battery Voltage Display

Battery voltage can be displayed on the

LED display, along with battery change
status

Red LED screen

Rev-Shift Function

The engine's speed (RPM) can be captured through either the alternator pulse or directly from the ECU. The shift light can be set to turn on and off at any RPM. For indicator purposes, the LED will flash in bright white when the user preset shift point is reached.

Timer Function

Auto Mode calculates (by driving style) how long a turbocharged vehicle's engine should run after the ignition has been shut off. Manual mode allows the driver to set the desired idle time manually.

A/F Ratio Display

A/F ratio can be displayed numerically on the LED display and in color ranges by the LED indicator. A/F ratio is calculated from the factory O2 sensor. Because most OEM O2 sensors are designed for emissions, the RST readings may vary compared to a wide-band A/F meter.
* A/F ratio readings will only work with Zirconia type O2 sensors.

Keep your eye on the prize, not your gauge.

Over-revving any engine can lead to disastrous results, but with a turbocharged engine the risk is even greater due to the additional air being forced into the combustion chamber. The integrated shift light in ARK Design's RST allows driver to know precisely when to shift to avoid over-revving. The RST's shift light is a bright white LED that can't be missed when in a driver's line of sight. The A/F ratio is displayed in a numerical value on the LCD, and also as different colors on the LED indicator.
