Delicious Tuning - V3 Flex Fuel Kit (with FutureFlex Technology) is a ground up redesign with the ability to switch from one vehicle or integration system to another with a simple firmware update and new harness. While we can now implement a Flex Fuel solution for many make and model vehicles with basic tuning ability, the Future Flex aspect allows us to update the firmware and harness quickly for when custom code integration is added by the aftermarket ECU tuning companies. This allows you to enjoy the benefits of ethanol now and in the future when the FutureFlex Technology changes.

The ground up redesign includes a 10X faster processor, a plug in harness for easy removal of the module, and improved weather resistance. All this included with our new Flex Fuel Sensor takes all the guess work out of determining what the ethanol/gasoline (petrol) ratio is in your vehicle. Our Flex Fuel system determines the content ratio between gasoline and ethanol content in the fuel. It then sends a signal to the ECU which dynamically computes the correct air/fuel ratios, ignition timing values, boost levels, cam angles, traction control and more based on the ethanol content.

Optional Sensor (includes connector and sensor) and Solenoid (includes connector and solenoid) upgrades:
- Fuel Pressure Sensor (compatible with all variants)
- Oil Pressure (not compatible with NexGen - GreenSpeed signal input)
- Oil Temp (not compatible with NexGen - GreenSpeed or MAF/IAT signal input)
- Electronic Boost Solenoid (compatible only with CAN signal input/output)

Flex Fuel (w/ FutureFlex Technology) Kit Input / Output Options:

- CAN Bus Integration - The CAN Flex Fuel Kit communicates over the vehicles CAN Bus network, because of that, no sensors are removed from the vehicle, no codes are disabled or altered, and the the installation is 100% plug-n-play with no wires are run into the passenger compartment. In most cases the OBD-II port is used as the CAN communication port, with a secure adaptor so that the OBD-II port can still be used unhindered.

- NexGen (GreenSpeed / Emissions Compliant) - A completely seamless E85 Flex Fuel solution for the latest while retaining all TGV functionality (only needed for 2008-2021 Subaru WRX/STI) on the latest Protune Software. Ethanol content and the optional fuel pressure upgrade can be monitored through the datalogs and natively through the Display Screen. Installation can be completed with the OEM fuel rail system and fuel pressure regulator, all from the top of the engine with no need to climb, crawl, or slide your way underneath the vehicle. All emissions related devices are still 100% operational with our Flex Fuel Kit as it was intended by the vehicles OEM engine management system.

- "Classic" TGV Input 3-Pin / 5-Pin (0.5V-4.5V) - Rear O2 Input (0.5V-4.5V) - Unterminated Input (0.5-4.5V) - The original voltage input options for various make and model vehicles running custom software looking for a simple and easy plug and play solution. This also has the optional add-on to incorporate the fuel pressure safety system in the case low side fuel pressure drops too low. These are "classic" modules as they replace your malfunctioning existing systems only, and are not compatible with new Cobb "Green Speed" and EcuTek "The Way Forward" initiatives.

- MAF/IAT Input (0.5-4.5V w/ Comp) - All emissions related devices are still 100% operational with our IAT Input Flex Fuel Kit(s) and the intake air temp is still being used as it was intended by the vehicles OEM engine management system. Our IAT Input Flex Fuel Kit(s) supports IAT (Intake Air Temperature) compensation and still measure/send the appropriate temperature signals to the ECU via our module for proper calculation over a broad range of temperatures (can integrate with Speed Density / Charge Air Temps). Compensation for cold start works as intended as we have implemented custom code in our IAT Input Flex Fuel Kit(s) that is transmitted to the ECU for proper startup on a range of ethanol blends.

Notes: (Specific Vehicles)

2022+ Subaru BRZ & 2022+ Toyota GR86
11-Pin and 8-Pin CAN harness Support - Due to changes in the harness from 2022 to 2023, there are two different connection options. Please review which harness you have prior to ordering. The harness connection can be found mounted by the strut tower bar on the left side of the vehicle (driver side in the US). Link to our instructions for further details on location.

2013-2016 Subaru BRZ & 2013-2016 Scion FR-S
OFT Flex Fuel Input - The ONLY option for application this is an unterminated end, and it only supported on the 13-16 model years. There is no Flex Fuel support through OFT on the 17-20 model years.
