Four-in-one, ethanol content percentage, fuel temperature, boost pressure, and wideband air/fuel ratio gauge
*Available for purchase with (PN 3906) or without (PN 3911) the Ethanol Content Flex Fuel Sensor (GM/Continental).
Definitely one of the best "all in one" combos. The sensor/gauge output can be used easily for flex fuel with Carberry for Subarus. However might not work with your standalone as some of them require a digital signal which this combo doesn't have as an output.
Works great very accurate definitely a must have running flex fuel tune
