Dynojet Power Vision 3 for Polaris Ace (2017-2021)
If your Polaris Ace feels flat off idle, hits a soft rev limiter, or runs rich after you've added a slip-on or intake, the problem is the locked stock ECU - it has no idea you changed anything. The Dynojet Power Vision 3 is the fix: it flashes your Ace's factory ECU with a corrected fuel and timing map in minutes, right at the trailhead, no laptop required.
Plug into the OEM-style connector, load a Dynojet tune matched to your setup, and the Ace pulls cleaner through the midrange, holds a higher rev ceiling, and stops dumping fuel. The same device doubles as a dash-mounted gauge so you can watch coolant temp, AFR, and RPM live while you ride.
As an EFI tuner for UTV use, this Dynojet PV3 tuner handles ECU flash for Polaris machines on the fly and works as a live data monitor for your UTV - a true flash tuner for side-by-side riders who want an off-road fuel tuner without a laptop. The free Power Core software from Dynojet lets you log and refine tunes at home, making this Power Vision tuning device a complete UTV ECU tuner solution.

Frequently Asked Questions
Do I need a laptop to use the Power Vision 3?
No. The PV3 flashes your ECU directly from the device. A computer is only needed if you want to use the free Power Core software to log data or edit tunes at home.
Will this work with my exhaust and intake?
Yes. Dynojet provides free tunes for common bolt-on combinations, and authorized Dynojet tuners can build a custom map if your setup needs one.
Can I go back to stock?
Yes. The PV3 stores your original calibration and can reflash the factory tune at any time.
Does it monitor engine data while I ride?
Yes. Mounted on the dash, the PV3 acts as a live gauge for AFR, RPM, coolant temperature, and more.
Is a tune included?
The device ships with access to Dynojet's tune library for supported configurations. Custom dyno tunes are available separately through authorized tuners.
Who is this tuner best for?
It's best for the 2017-2021 Polaris Ace owner who has added an exhaust, intake, or filter and needs the locked stock ECU corrected - and anyone who wants a higher rev ceiling plus live engine monitoring without a laptop or dyno visit.
