    • Bluetooth and 50-150hz Raw Signal for those that are connecting their analyzer to an aftermarket ECU or the DME.  This option puts out the same signal the Continental sensor does.

    *If you aren't sure whether this kit fits your car, send us a picture of your engine bay with the engine cover removed to info@fuel-it.com

    *Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated.
