Customer Reviews


Works for me

By Tim B. on  Verified Purchaser

Good tuner, I would rate it equal to the Fp3 on my other bike. The diagnostic features that are available are a game changer. Payed the extra 50 bucks to purchase the ABS bleed tool license and now I have it whenever I want to flush the system. A ton of added tools you can pay a license fee for that I will never use. People complain about the added purchase for tools but I think they are reasonable. When I flush the brakes again next year that alone will have payed for the tuner. Easy to use and good customer service. Do it yourself or let Harley do you dry.

Questions & Answers


Will it allow Wheel change size

By Anon.

I put after market wheel on my trip glide and traction control light came on and abs light and runs like parade mode pit origami wheel back on it and goes like it did factory no lights so will your product help fix my issues

Yes, the PV4 does have a speedometer recalibration feature, which is pretty nice! Just use companion phone app and the Vehicle Speed Sensor (VSS) EEPROM setting as needed there. It's a rather simple process to change ... a log easier than swapping out wheels. :D
