Terrible product

Terrible product and no customer satisfaction. The FP4 will not support a a cam which is not stated anywhere in their disclaimer. Not looking like I will receive a credit/return so I am stuck with a $500 paper weight. DO NOT BUY

Very disappointed... Samsung owner

The only thing this thing did was cause a check engine light to come on. I should have gone with the fp3, but noooo I wanted the newest and best. Welp I got the newest.

What a let down!!

Super disappointed, I am a big fan of the fp3, used them on all my bikes so when this came out I was not worried. Well shame on me. Had trouble right from the start. I had to call the company to give me a work around a firmware error. Cant even look at error codes on iphone, just seems like the company didn't really care about us this time around. No update yet to fix issues. As far as the tune its not great, just super disappointed. Normally I would brag to people how good their stuff is but I would say stay away from this. When you call the company all they say is "Um, we are working on it".

Buyer beware

BEWARE! If you have an iPhone, do not buy this. It simply does not work. You will not be able to flash a map or auto tune. I don?t understand how they can release a product that is so fundamentally flawed. V&H?s support response is ?find a friend with an android phone, and borrow their phone?. Are you serious???!!!! This is uncharacteristic of V&H.

DO NOT BUY THIS PICK ANOTHER TUNER IT DOES NOT WORK AND THEY HAVE NO CLUE TO WHEN IT WILL. BUT THEY ARE GLAD TO TAKE YOUR MONEY.

The FP4 tuner does not work. If you have a iphone you can only load a map/tune. You can not look and the maps fuel or air ratio to see the changes, you can not autotune, you can not even adjust the decel pop like Advertized so only maybe15% is working. On andriod you ca nsee the fuel ratio when you load new map but there is still no autotune, decel pop adjustment, and only work about 40% of the function. It has been out for months and not fixes. Should not have been released and for sale when it does not work. When you call them one tech will tell you yes that works so you try it and it don't. You call back and another tech will tell you they are working on it so those option (Autotune/Decel pop/and fuel/air ratio funtions do not work) They will not offer to return your money for buying something that does not work jsut tell you we are working on it.
