Kit Update Highlights (more info outlined in description): Now Optional Full Flex Fuel Tuning for 15-23 Ecoboost Mustang, 16-18 Focus RS, and 2015-2018 Focus ST TunePlus, Inc Exclusive Reflex Controller Canbus connections to reduce amount of wiring New Fittings for cleaner/sleeker look, and ease of install OEM+ Features Capability (Anti-Lag Launch, Rolling Boost, High Idle, Burble) Remote software support included! 06/11/2026: We have redeveloped this kit to offer a more simplistic install, as well as adding the powerful feature of FULL FLEX FUEL support. That is right, no need to change your tune at all when switching between fuels. The Flex Fuel version of our kit will automatically update your vehicles tune and the port injection in real time. That means you can have any mixture between 0% and 85% ethanol and the sensor will feed ethanol content data directly into your vehicles factory PCM and will adjust the tune. Other companies require you to switch tunes on the vehicle while their port injection ONLY may change based on ethanol content. However with our kit, that is not needed. Your tune will update in real time, never have to flash your car again! We already offered a Flex Fuel kit prior to this update, but using XDI pumps and injectors. You can see more information on this here. We wanted to offer a more affordable option for customers, along with the benefits of port injection, but with full Flex Fuel capability. In addition to adding flex fuel support we have removed the need for hardwiring for most input signals to the controller. Now all data comes through the vehicles Canbus network. So no longer do you need to tap each coil pack, map sensor, or crank sensor wires. Simply hook up Canbus, Cam Signal Wire, and give it power. Not only making the kit more simple to install, but MUCH cleaner. This Canbus connection also handles the Ethanol Content data to the PCM, giving us that sweet sweet Flex Fuel capability. This is a TunePlus, Inc EXCLUSIVE product. This kit cannot be tuned by any other tuners, and your current tunes will not carry over. We will tune the car from start to finish for both pump gas and E85, and flash custom software that will handle all the flex fuel blending between the two finalized tunes. You must already be a TunePlus, Inc tuning customer, or you will need to purchase our Dual Fuel Tune, or Unlimited Tuning options. You do not need to purchase our Port Injection Tuning Add-on when buying this kit. Options Breakdown: Non-Flex Fuel Kit: This kit does not include an ethanol sensor, this is simply a port inject injection to provide more fueling for your setup. You can still run E85 on this kit but you will not have real time ethanol content reading, nor flex fuel capability. You will be required to change the tune on the controller and your vehicle when switching fuels. Bluetooth Kit: Same as the above kit, but we include an ethanol content sensor as well as a Bluetooth Analyzer that will send real time ethanol content to your Apple or Android phone via Reflex App. Flex Fuel Kit: Fully optioned kit, includes ethanol content sensor, flashing cable, software license, and everything needed for Full Flex Fuel tuning w/ Port Injection. Flex Fuel Kit w/ OEM+ Features: Same as the Flex Fuel Kit above, but includes the OEM+ Features outlined below OEM+ Features: This is something we have offered to all our customers as an option. With our Flex Fuel Software we have the ability to add cool things like Anti-Lag Launch, Boost On Demand, Rolling Boost, Burble Switch, High Idle, and soon more cool features. This turns your factory PCM into a powerful unit, giving it nearly standalone-like ECU features. Nobody else offers nothing like it. More Information: Remote software setup is included with your purchase. We will remote into your PC after install and setup all the software for you. Taking the need to read through pages and pages of how to install software, open files, connect this, upload that, etc. We simply schedule a time to remote access your PC while plugged into your vehicle and set everything up for you. Will take about 5-10 minutes in total. Kit will support up to 600whp with the stock pump/injectors. If you are making more than 600whp please email us for bigger injector options as well as an upgraded HPFP. Focus RS Customers - If you have upgraded Aluminum/Steel chargepipes on your car you will need a HPS Offset Coupler in order to mate up to the throttle body as it is moved forward when you install the spacer.
