Initial Sputtering on Start Up After Auto Tuning w PV
So I've been running a map that I got from Fuel Moto and I finally got around to auto tuning and before I even started riding, when I started the bike (I put the PV in auto tune before starting the bike), here was some kind of flashing over the auto tune cells saying "warm up" or something. I noticed right away that if I gave it some throttle, it would sputter and want to die. After like a minute, it was fine...
Rode 10-15 minutes and installed the auto tune corrections, then rode another 10-20 minutes and installed that one.
My bike feels like it is running a lot smoother and has better response. It felt like it was still running pretty hot but it definitely was running better.
So the next day, I unplug my PV and it still does this sputtering for like the first minute after initial start up. It never did that before my auto tuning began.
I'm wondering if I should re load the original tune and not start the tuning process until the bike is running already.
It never sputtered before and my buddy said he saw smoke coming out of the pipes at start up. So I'm thinking it's running rich at start up for some reason instead of lean.
Anyone had this issue with the auto tune basic?
Appreciate any insight here. I have a long trip coming up and don't want to screw anything up.
P.S. Forgot to add my set up: Drago's H Pipe w Dragula's, FM AC and PV.
