When it comes to turbocharged vehicles two of the major factors in maintaining reliable performance are proper oil cooling and not over-revving the engine. ARK Design's REV-Shift Timer was developed specifically to combat these factors. The REV-Shift Timer 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 compliment each other in any vehicle's interior.

The REV-Shift Timer's auto timer function automatically calculates how long a turbocharged vehicle's engine should run after the ignition has been shut off to prevent oil-coking. By allowing a turbocharged engine to run at idle oil is circulated through the turbocharger, effectively cooling the oil. If the oil is not out allowed to circulate, the oil will sit inside the turbocharger and can solidify into small crystals (oil-coking) which overtime can damage a turbocharger seals and reduce performance.

Over-revving any engine can lead to disastrous results, but with a turbocharged engine the risk is even greater due the air being pushed into the combustion chamber. The integrated shift light in ARK Design's REV-Shift Timer allows drivers to know precisely when to shift to avoid over-revving. The REV-Shift Timer's shift light is a bright white LED that can't be missed when in a driver's line of sight.

In addition to the auto timer and shift light of ARK Design's REV-Shift Timer, the LCD screen (available in blue or red) can display Air Fuel (A/F) ratio and battery voltage. The A/F Ratio is displayed in a numerical value on the LCD, and also as different colors on the LED indicator.

RevShift Timer Manual

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 drivers to set the desired idle time.

Rev-Shift Function

• 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. The LED indicator will flash in bright white when the user preset shift point is reached.      

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 Rev-Shift Timer's readings may vary compared to a wide-band A/F meter. (A/F ratio readings will only work with the Zirconia type O2 sensors.

Battery Voltage Display

• ·Battery voltage can be displayed on the LED Display along with charge status
