Keep in mind the ethanol percentage can be lower during the winter months in some areas. The remaining 15% of the fuel is traditional gasoline. Q: What is E85 and why does it easily give so much more power?Ī: E85 is a biofuel composed of up to 85% ethanol. Also, Hondata's base settings are usually good enough to run the engine temporarily, but custom tuning is highly recommended. IMPORTANT NOTE: These kits are only compatible with the Hondata S300 v3 and K-Pro v4 systems, and the purchase of this product does not include a Hondata S300 or K-Pro. Your tuning device will automatically adjust on the fly for your current fuel mixture. It can have any combination of E85 and non-E85 gasoline in it. TIP: Your gas tank is not required to just have all E85 fuel in it after installing this kit (hence the name Flex Fuel). Combined with a tuning device, it converts your Honda Civic to run on higher concentrations of ethanol (like E85) than is in standard pump gas. What is a Flex Fuel Kit in simple terms? It is basically a special sensor installed along one of your fuel lines that reads the amount of ethanol in your fuel, produces a signal, and sends a processed version of that signal to your ECU for use by your tuning device.
