Pc-v

I recently change exhaust from 2-1-2 with a Screaming Eagle race tuner to a 2-1 and PC-V. My bike runs good, no decel popping however: it's doesn't start up very easily. I have updated the firmware on the PC-V and Fuel Moto has sent a new map but it has not help with starting. So today, I took the disconnected the PC-V and the bike starts right up with the touch of starter.

Any thoughts on why my bike is so hard to start using the PC-V but not the SC race tuner?

I have the Power Vision on my Road King. With the MAP provided from fuel moto it was running a little rough when i first would fire her up. Had it stalling a few times also. Just this past week in the cold in the 20 s. Once I rode it awhile it smoothed out. I ran an auto tune and now it's a lot better. But looks like you have the power commander

did ya have a custom dyno tune with the sert,if ya did, did ya tell fuelmoto. the programing that the sert put in your ecm will not allow u to tune with a pc unless u return it to stock first.

I did not have ecm back to stock and was told by several others that could be whats causing this. I will take it back to my local dealer and have them set the ecm back to stock. Thanks

I would add 5 to all cells in the fuel tables except the first column in the first three rows. You can leave them at 0. The 2 in 1 needs around 5% more fuel due to the better exhaust evacuation. The best thing would be to reset to stock numbers.
