Four-in-one, ethanol content percentage, fuel temperature, fuel pressure, and wideband air/fuel ratio gauge
*Available for purchase with (PN 3903) or without (PN 3910) the Ethanol Content Flex Fuel Sensor (GM/Continental).
Great combo gauge
My local shop and tuner both recommend this route for flex fuel tuning
Thx to Cobb AP this goes right into the ECU
