Street 750 With FP3. Gas Smell

Hi Guys,
So i have the two brothers exhaust, vance and hines naked air filter system and the FP3.
I set it to the V&H exhaust slip on with no baffle as the tuner map.
Then i set it to auto-tune. The bike sounds better and runs better, but when i'm stopped and turn it off, you can smell gas.


Is this normal? Did i use the wrong mapping? Is there a mapping i should use?
Also after my ride, there was no info showing in the auto-tune mapping on my phone.


Please help me, i want to be sure it's done right.

When you run the autotune, FP3 is not doing anything to the bike. Infact it might run worse for a short time as it gets all the data it needs to build your new map. The changes do not go into effect untill to finish the process and actually map to the revised map to your ECM. You'll notice the difference then. You should be able to see most of the squares as green with some orange before you map it. once mapped you can also modify the amount of decel pop if any in there by selecting the appropriate amount of dynamite sticks

It might be from the Overflow Hose. Sticks out the bottom. In front of the rear wheel. Heat from the engine. Expansion inside the tank.
