Polaris Ranger 900 G4 ECU ECM Tuning Service and Clutch Kit
Gilomen Innovations has spent countless hours developing and testing our 2013-2019 Polaris 900 Ranger and 900 Ranger Crew G4 ECU Flash tunes and clutch kits. We are known world wide for our Ranger ECU tunes and clutch setups because they flat out perform! This tune is for all 900 Ranger models from 2013-2019. We even have special versions of this tune specifically for the Highlifter and Hunter Edition models. We have unlocked all the limiters in the ECU to achieve MASSIVE horsepower gains throughout the RPM curve. The factory ECU programming only allows 40% of the available power when the throttle pedal is pressed 100%. With our G4 tune you get 100% of the available power when 100% throttle pedal is applied. There are many areas in the ECU maps that I change to get rid of the EPA friendly boggy lean condition at part throttle cruising. This allows your motor to run cooler, last longer and be way more responsive. This tune greatly increases your Rangers ability to do work, farming tasks, and take you to your hunting location because of the better low speed drivability and way more power on tap for when you get into sticky situations and need power to get you thru. Max power is 78-84HP at 7500-7800 RPM after this tune depending on the year. Top speeds can exceed 70MPH. Custom tuning options are available if you have a special application.

Clutch tuning is absolutely needed with this tune to let it perform properly. That is why I offer this ECU tune with a clutch kit to allow the engine to run at the RPM where peak G4 hp is. The stock clutching is designed to run at 6100-6400 RPM which is way too low for this tune. If you want full potential out of this tune you NEED to re-clutch. The clutch kits we offer are designed around the power profile of the tuned ECU. Our clutching gets rid of the horrible factory clunk / jerk at take off that the 900 ranger is known for. Take off is very smooth yet very responsive. I have had many people comment how smooth the machine drives after our clutching and ECU tune. Drivability at slow speeds is greatly improved! The Elite Shift clutch kit that comes in the ECU tune kit includes primary clutch spring and weights along with detailed install instructions and torque specs. No special tools or pullers are needed to install the clutch kit. Most people can install the clutch kit in 30 minutes. Once you get the ECU and clutch kit simply install the clutch kit and plug in the ECU and you are ready to go. If you are running larger than 29" tires you will need to purchase the Mudder Secondary Spring which will squeeze the drive belt harder preventing belt slippage. Price includes shipping to you. Turn around time is 1 business day. You can have faith in us to give you the best possible customer service. All of our tunes are developed in house with the best strategies known.
I have had several people ask if their heater will work as good in the winter after the 20 degree cooler fan temps and the answer is absolutely yes. I have tested this during the harsh winter in Minnesota on my personal machine and found the heat works exactly the same. The reason for this is because the engine has a 180 degree thermostat and during the winter the cooling fan rarely comes on with or without a tuned ECU but the thermostat is always maintaining proper engine temp to keep the heater core hot.
UPDATE 3/12/2018 Many Polaris models with stock ECU programming suffer from false misfire codes ( 65590, 65591, 65592 ) due to drive belt issues, excessive tire spin, constant high speed driving, or for no apparent reason at all. Polaris made these codes way too sensitive & are unable to delete the codes. Our newest version tunes 3/12/2018 and later will eliminates the false check engine codes 65590, 65591, 65592!! If you are a Polaris dealership that has unhappy customers because of these false codes please call us, we can help restore your customers faith in their new Polaris machine!
