Ratings and reviews

So far, it works. It takes several tries to connect the phone and FP4. But once it connects, it seems to work. I've done "auto tune" three times, so far. I'll update this when I'm done. I had an FP3 and it worked perfect. Sadly the FP3 is gone. Up-date: After two software updates FP4 is worse than before. It often takes so long to connect the phone to the FP4 that the bike is hard to start. 1 in 5 times, I give up. If it works, DON'T FIX IT.

*UPDATED REVIEW* While i am still pretty disappointed in FP4 (FP3 still is a fantastic product), the connectivity has improved quite a bit as of 5-5-24.... i was able to actually use most of the adjustments i was able to access in the FP3, and they do have a few more exhaust brands available now... So, as such i'm going to raise my star rating to 3 stars due to improved operation... i'm still pissed about getting used as a beta tester for full price, but, things appear to be improving....

I've used multiple android devices and a chromebook. "Fails to connect" on every device. Reinstalled on every device, lights on FP4 are on. Motorcycle is in running mode. Unfortunately, nothing seems to make the app connect to the module. By a miracle on the 3rd android device used, it managed to connect, but this "app" failed to connect to the internet, which every device was able to. EDIT: 7 different phones further: GOT IT TO WORK WITH A >>>''GOOGLE PIXEL 6a''<<< SMARTPHONE!!!!!!!!!!!!!!!!!!!
