Accurate ethanol content, in real time

A genuine VDO Continental compact flex fuel sensor (VDO SE1004S). It reads the ethanol content and temperature of the fuel passing through it and sends that to your ECU or flex controller, so your tune can adjust fuelling and timing automatically for whatever blend is in the tank.

Genuine Continental sensors give accurate, consistent readings – cheaper copies are known to read ethanol content incorrectly, which can lead to lean running.
