COBB Tuning Flex Fuel Upgrade Kit Audi | Volkswagen 2015-2021
$245.00
Free Shipping
The Flex Fuel Upgrade Kit for VW/Audi vehicles makes adding Flex Fuel functionality to your vehicle and existing ECU a breeze. This kit consists of an ethanol content sensor with bracket, bespoke wiring harness, a fuse tap harness, quick connect fuel fittings, and a super slick ECU pin locator template and pin tool. We've bundled everything you need to get on corn in minutes!

This kit seamlessly integrates with the factory ECU and the provided pin locator tool takes the guesswork out of the equation. The OE quality ethanol content sensor is secured to a bespoke powder coated aluminum bracket. Fuel is then fed to and from the sensor with pre-made fuel line with OE quick disconnect.

The ethanol content sensor is mounted on the passenger side engine mount and instantaneously reads the ethanol level in the fuel multiple times per second before sending that to ECU to be used by an Accessport-delivered Flex Fuel calibration.

Included as a part of this release are a set of COBB Off The Shelf Maps that are specifically calibrated for use with the Stage 1 package. All maps have been optimized for use with a completely stock fuel system, aside from the installed COBB Ethanol Sensor Kit. As such, they are configured to produce maximum power at an E30 blend. Any ethanol concentration beyond that level will result in a custom COBB DTC (COB13) and a reduction in power. Reducing the ethanol content to E30, or lower, and resetting the ECU will clear the DTC.

Upgrade Kit is for USDM models only and requires use of either COBB Flex Fuel OTS map or custom tune from an authorized protuner.

Why?
Our COBB Tuning Flex Fuel Upgrade Kit for VW/Audi measures the ethanol content level of the fuel being pumped into your engine and then sends that data to the ECU to be used in a Flex Fuel calibration.
