2019 fxbb. Bike was running rough at 60,000 miles. Did install aftermarket pipes ,but otherwise stock. Ruined one O2 sensor, replaced and tried this simple fix. Easy to use, connection is easy. Firmware update, picked the tune. Easy to navigate, cleared errors. The tune fixed my lean rear cylinder and 02 codes that would pop up randomly.Simpe solution for a simple mostly stock , everyday ride. I've read all the reviews, I think some of the problems are possibly user error. I could be wrong,

It was simple and easy to use. After reading the instructions and the conversations with the help line. My bike runs better than ever.

Thanks to this Tuner my bike (2019 Harley Fatbob 114) has never ran better. The Good: Simple to use and found a "Tune/Map" that fixed all my Stage-1 "too lean" issues. The Bad: Very limited factory tune choices. No factory video/instructions; although found many user videos/instructions on-line. While I am 100% happy with the final tune and would definitely buy again; the limited choice of custom Stage-1 tunes was/is a little lacking; however, found one that really "turned -on" my bike. Wish I would have done this 8 years ago. After a few "auto-tune" sessions/ corrections did not really change performance much from the pre-canned tune. However, 100% happy with the pre-canned tune and now bike pulls-hard at every RPM. It also runs cooler and performs better especially while "warming-up." Used to " fall-on-it's-face" during warm-up (too lean).

Downloaded Dynojet's app. Simple as it gets. Plug tuner into my bike. Update firmware. Bam! I'm in. Straight to the tunes I go after I check for any codes to clear. No codes. On to the tunes i go so I can flash for the new hi flow intake I just bolted on. Tunes page. Simple I find a tune for.my bike my year with the mods I've done. Hi flow with slip ons. Select, flash. Then bike off for ten seconds. No problem. Im.gonna grab my helmet anyways I wanna ride this tune. My bike is running better than stock. Sounds better. Throttle is crisp. And it pulls like a freight train when I pin it. This tuner flashes so easy. I've read about guys getting terrible running bikes after bolting on aftermarket. No kidding. Ya gotta tune This tuner flashed as about easy as it could possibly get. Worth every single penny. This tuner will keep my bike running at peak throughout my build. And when I'm done with my build I can get my bike dynoed and store all my tunes in this tuner. 5 star5stars5stars I salute you Dynojet.

Great tuner. Would purchase again.

Installed on my bike but only had two options for tuning, either slip on mufflers or entire exhaust. There was no choice of different exhaust manufacturers or types. Chose the best fit, but the bike ran like crap. Lots of decel popping and bike seemed lazy in lower gears. No options to auto tune or manually making adjustments. You’re simply stuck with the limited options provided. I’m just going to have my bike properly dynotuned.
