About ECU Tuning:

Throughout our extensive R & D experience, we found that recalibrating the ECU/ECM is the best way to get the most out of your machine. We do this by taking the time to go through the entire ECU and optimize it from the ground up. Something that was not commonly done in current ECU tuners. This way we can tune it to as close to perfection for every scenario to outperform your current programming configuration. Your machine will be tuned and perform just as well as a machine that was on the dyno and tested for months on end so that it excels in every situation to be smoother, faster, more efficient, and more reliable.

Sending us your ECU is always the easiest and preferred way to get it done, but for those that wish to purchase a tool to flash their own ECU, we are using the new industry leading EZ LYNK Auto Agent 3 system. This will not only allow you to flash your ECU but you can also do much more.

• Data Log live and record data to share with tuners or friends.
• Run diagnostics checks on your machine as well as several other powersports and over the road vehicles. (brand-specific cables required for other powersports machines)
• Reset power valves on Polaris 850 and 9r models.
• Flash your own ECU with optional ECU Flash Power-Up Adapter
