We’ve raised the bar when it comes to what you should expect from a fuel tuner. Power Vision 3 for Harley M8 easy-to-read, no-nonsense display puts performance at your fingertips, empowering you to choose from our vast library of pre-tested tunes or to build one yourself. The Power Vision fuel tuner updates the tables directly within the ECU to optimize the air/fuel ratio, keeping you in sync and in control. When you’re back in the garage, your performance data can then be clearly seen using our Power Core software to help you improve your ride. The Power Vision device holds multiple tunes at once and allows you to optimize your ride for power, speed or fuel-efficiency. After you’ve flashed your ECU, you can either unplug the device or head out with Power Vision attached as an extra instrument panel. Power Vision easily connects through the OEM-style connectors, so installation won’t keep you away for long.

Power Vision 3 for Harley M8 can hold multiple tunes right on the device, which means that you can reflash your ECU right from the road to keep up with changing conditions. Keep a tune available for each of your favorite upgrades and drive styles to optimize your motorcycle for everything you need. Not just an EFI tuner, Dynojet’s Power Vision devices are also powerful monitoring tools to track your progress as you ride. The data can then be viewed using our Power Core Software to help you improve your tune. It can also be used as an extra instrument panel when mounted to the bike for even more control over your progress.
