Technical Notes:

The PRL Motorsports Plug n Play WiFi Flex-Fuel / Ethanol Content Analyzer Kit allows customers to wirelessly monitor ethanol content via any smart device or enable flex fuel via an optional 0.5-4.5V configurable output with a tuning device. Our innovative Patent Pending design utilizes the factory fuel line, which eliminates the chance for alternative fuel line deterioration and improves aesthetics. This kit utilizes factory plugs/outputs under the hood for power and communication to the ECU, meaning no need for additional wiring, cutting, splicing or running wires to the fuse box or through the firewall into the cabin! All hardware and bracketry is include for quick and easy installation. Kits can be installed and uninstalled within minutes. Please note that our kit does NOT utilize an ethanol content gauge, as we feel that this is unnecessary. Hondata and KTuner V1.2 both offer Bluetooth capabilities, while the KTuner V2 LCD screen can be used to display ethanol content if desired. All components are ethanol compliant!

Did you know that the factory fuel line assembly is actually Teflon and extremely resistant to ethanol-base fuels?

The factory fuel line is actually constructed with an EPDM (fuel and oil resistant synthetic rubber) outer hose and inner ETFE (another Teflon coating that is similar to PTFE) liner, which offers great resistance to a variety of fuels, including ethanol-based fuels. Because of this, there is no reason to “upgrade” or replace the factory fuel line assembly when used with this Ethanol Content Analyzer / Flex Fuel Kit unless kinked or damaged (please note the “Do Not Kink” Warning located on the line).

Why Run Ethanol?

Due to rising gas prices and the push for alternative fuel sources, ethanol, derived primarily from corn, has become a common, cost-effective fuel choice. Ethanol has now found its way into most modern gas stations and the community now understands its list of benefits in comparison to gasoline, such as the fact ethanol burns cleaner, cooler and is more resistant to detonation. Because of these characteristics, ethanol is a cheap alternative to expensive race fuels like race gas and/or methanol, especially with high(er) compression factory turbocharged vehicles. E85 = 85% Ethanol and 15% Gasoline whereas E30 = 30% Ethanol and 70% Gasoline and so-on.

What is Flex Fuel?

In a nutshell, flex-fuel allows an internal combustion engine to flexibly utilize one or more different fuels (usually gasoline blended with either ethanol or methanol fuel), and both fuels are stored in the same common fuel tank. Flex-Fuel systems utilize an ethanol content analyzer to determine the amount of ethanol in a fuel system and a converter to send this reading to the vehicles ECU to instantaneously adjust for varying fuel mixtures.
