Technical Notes:
Our PRL Motorsports Plug-N-Play WiFi Flex Fuel / Ethanol Content Analyzer Kit allows users to monitor ethanol content wirelessly via any smart device or enable flex fuel via the optional 0.5 - 4.5V configurable output with tuning devices. Our innovative, patent-pending design utilizes factory fuel lines, eliminating the possibility of alternative fuel line degradation and improving aesthetics. This kit utilizes a factory plug/output located under the hood for power and communication to the ECU, meaning no additional wiring, cutting, splicing, routing to fuse boxes, or running wires through the firewall into the cabin. All hardware and brackets are included for quick and easy installation. The kit can be installed and uninstalled within minutes. Please note that we do not believe an ethanol content gauge is necessary with our kit. Both Hondata and KTuner V1.2 offer Bluetooth capabilities, and the KTuner V2 LCD screen can be used to display ethanol content if desired. All components are ethanol compatible!
Did you know that the factory fuel line assembly is actually Teflon and highly resistant to ethanol-based fuels?

The factory fuel line is actually constructed with an EPDM (fuel and oil resistant synthetic rubber) outer hose and an inner ETFE (another Teflon coating similar to PTFE) liner, providing excellent resistance to various ethanol-based fuels. Because of this, there is no reason to "upgrade" or replace the factory fuel line assembly when using it with this Ethanol Content Analyzer / Flex Fuel Kit, provided it is not kinked or damaged (please note the "no-kink" warning on the line).
Why use Ethanol?
With rising gas prices and the push for alternative fuel sources, ethanol, primarily derived from corn, has become a cost-effective and popular fuel choice. Ethanol is now present at most modern gas stations, and the community is now realizing the benefits of ethanol compared to gasoline, such as the fact that it burns cleaner, cooler, and is knock-resistant. These characteristics make ethanol an inexpensive alternative to expensive racing fuels like race gas or methanol, especially for high-compression factory turbocharged vehicles. E85 = 85% ethanol, 15% gasoline; E30 = 30% ethanol, 70% gasoline, etc.
What is Flex Fuel?
In a nutshell, "Flex Fuel" allows an internal combustion engine to flexibly utilize one or more different fuels (usually gasoline mixed with ethanol or methanol fuels), with both fuels stored in the same common fuel tank. The Flex-Fuel system utilizes an ethanol content analyzer to measure the amount of ethanol in the fuel system and uses a converter to send this measurement to the vehicle's ECU to adjust instantly for various fuel mixtures.

Before Ordering
〇 About Import Taxes
At Shaftoya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
Since all product databases are based on North American vehicles (USDM), please check whether the installation is possible for Japanese vehicles (JDM) before placing an order. (If you are not sure if the listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you order without checking compatibility, we cannot accept returns due to incompatibility.
Please note that even if a product is sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, it does not necessarily mean it will fit the Japanese model vehicle without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Delivery
Shipping costs are paid at the time of payment. The shipping estimate is automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automatic calculation. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us to check the delivery date in advance. Note that all products are transported by air. They are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. For items with shipping damage, defective products, or products different from what was ordered, we will provide returns, refunds, or replacement exchanges only if contacted within 7 days of receipt. Please understand that for products sold through us, we will handle warranty matters "only through us." Please note that we do not provide support through other companies or distributors located in Japan.
