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. Auto-mode and A/F for vehicles without zirconia O2 sensor or where O2 sensor deterioration has occurred, some of the displays and/or functions may not operate correctly. Some vehicles may not be able display accurate rev, in such case, connection to rev signal line (ECU) may solve this issue. This product is for DC12V negative earth vehicles. Note color choice of Red LED or Blue LED during checkout.
