Description
The PRO R 4 CYLINDER ecu tune is here, and this tune is awesome! This performance ECU tune is a premium 91+ octane pump gas friendly trail version tune offered by Gilomen Innovations for the PRO R 4 CYLINDER models. 100+ octane Race fuel type tunes are available if special requested. All engine protections are left in place, so your engine stays running safe. Fuel and timing maps revised for peak performance. The cooling fan on temp is lowered from 205F to 190F degrees to keep your engine running cooler and lasting longer. Rev limiter is raised to 9000 RPM, Speed limiter in high gear is eliminated, Speed limiter in low gear raised to 45 MPH. Once you get the tuned ECU from us, simply plug it in, and you are ready to go. Polaris rates these at 225 hp in stock form. We see that they are underrated from the factory because dyno testing has seen 228-230 in stock form. This tune brings your power up to 255-260 hp. Price includes shipping to you. If you are sending us your ECU, it is your responsibility to get your ecu to me. Turn around time is 1 business day which means we will tune your ecu, and it will ship back out of our tuning facility the business day after it received. Custom tuning generally takes an extra day or two.
Our performance clutch kit is recommended to provide more belt grip and proper shift phase rpm, so the engine runs within the power band of the performance tune.

If you are sending in your ecu for tuning, please ship it to us here:
Be sure to place an order for tuning before you send your ecu, so we can match your ecu up with an order when it arrives here. If you send your ecu without placing an order beforehand, it can cause a day or two delay because we will need to reach out to you to gather information for the tune and customer info.
