As many of you know the B58 motor is very picky about how much ethanol you run to achieve peak performance but not run lean. Consequently we have put together a kit enabling you to easily install an ethanol sensor with no permanent modifications needed. You will simply remove disconnect your fuel line where it enters the engine bay and plug in our kit. I't a completely plug and play solution that utilizes out Bluetooth app to monitor your ethanol content. When you are ready to return to stock, you will simply remove the kit and re-attach the stock connections.

Complete Kit includes:
Two E85 compatible -6an fuel lines
Custom anodized billet fittings
Ethanol Sensor
Bluetooth analyzer with an optional 0-5 volt analog output for use with the JB4 or analog gauge
Bluetooth (Iphone or Android app must be purchased to use this feature)
If you are using an Apple product the app can be found by clicking here
If you are using an Andriod product the app can be found by clicking here
*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.

*NOTE: To simplify installation of the kit, the Bluetooth ethanol analyzer does not include any other integration for JB4 as it's not needed at this time. In doing this all plumbing connections and electrical connections can be made under the car. If you prefer our traditional analyzer with the 0-5 volt output as well as Bluetooth, those connections will need to be made in the engine bay and you must request our traditional analyzer that will be included at no additional charge.
