Rolling Wrench GY6 Plug & Play EFI kit
2 years of RnD and our GY6 (150cc, 171cc & 190cc) plug & play EFI system is out! This kit wasn’t easy! We beta tested over 50 of our kits, tweaking them along the way to make for the perfect EFI kit (of course we will alway keep improving if necessary). This kit has finally made it to our website!!!! This is not a generic EFI kit. The Rolling Wrench EFI system will come with a pre-loaded base tune (the base tune we spent years developing). No need to know how to use tuning software ever again. In fact, you won’t even have access to the tuning software. If you want to make changes to the provided tune, we include our Rolling Wrench hand tuner in this kit. You can increase or decrease fuel on the fly with the push of a button in 500 rpm increments. All of the wiring is plug and play with the perfect length of wire for your scooter, buggy, or ATV. YOU MUST HAVE a 11 pole stator installed into your GY6, anything less you will have charging system issues (not enough stator power). The power wire is the only wire that is not plug and play. Most people tap into the taillight power with the supplied solder joint. Although if you are running the Rolling Wrench ruckus harness the entire system is 100% plug and play. The only real time consuming thing (45 min) is mounting a return line in the gas tank (refer to the video). We have tunes available for the GY6: 150cc, 171cc, and 190cc currently. This EFI system will adjust for atmospheric pressure (temperature outside and altitude) via the map sensor. Although you will need to first fine tune the fuel mixture with the provided hand tuner. It also comes with an optional narrow band o2 sensor that can be welded to the exhaust for auto tune from idle to a cruise speed 4K rpm (13.3 afr).
