Flex Fuel Sensor Kit / Ethanol Content Sensor

An ethanol content sensor becomes a HUGE asset when you’re running a standalone ECU. 

It gives the ECU real‑time data about the exact ethanol percentage in your fuel.

That matters because ethanol blends can vary wildly, and your engine’s ideal fueling, ignition timing, and boost targets all depend on that percentage.

With a flex‑fuel sensor feeding live data, your standalone ECU can automatically adjust those tables on the fly. The result is smoother drivability, safer operation under high load, and the ability to take full advantage of higher‑ethanol blends without manually swapping maps.

It essentially turns your setup into a smart, adaptive system that always optimizes power and reliability based on what’s actually in the tank.
If you’re tuning for performance, it’s one of those upgrades that pays for itself in consistency and peace of mind.

Our kit features:

• 1x Genuine Continental Ethanol Content Sensor
• 2x Quick Disconnect to AN Adapters (avail. in 6AN & 8AN)
