Whats goin on there fellas and ladies of course ! I have a problem with my bike that I am trying to figure out and I don't know how much effort the dealer is putting into this problem so here I go with the problem and maybe you guys can tell me or point me in the right direction. I have an 06 which from the dealer had the stage 1 done plus slip ons and I added the true duals, I then proceeded with dynoing my bike with a pc3. I then added se 203 cams but no dyno only a copy of map from the web site. Now prior to having cams done I was having no problems starting my bike time and time again. Now that the cams are in bike cold no problem starting, bike warm little problem, bike hot real problem starting ! The only way I solve the problem is I have to give the bike a little throttle to get it started, I thought it was a problem with my bike and the crank position sensor was going bad and that is why the light came oon sure enough the code was the crank position sensor dealer changes and claims the bike is fine now. Nope the bike still has the same problem and the check engine light has not come on again. As I was saying before I thought it was my bike but my buddy has the same bike same year same color and equipment but different acc. anyway he is having the same problem and he nor I can figure it out help if you can.

 

Possibly the idle air controller needs adjustment because the cam used vs throttle plate position is not allowing enough mixture to fill the cylinder or the wrong a/f ratio and you can't light it off. Or, at hot start settings in the a/f ratio tables maybe too rich. I would have them scan the idle air controller when engine is hot and you try to start and see what the reading is.....if not in spec...adjust.

 

Try disconnecting the PCIII and see if it starts OK then.

 

yep what they said .
Higher lift longer duration means engine is capable of drawing in more air.
But you need to manually adjust things to get more fuel also.
I would definitely recheck you AFR across the band (start,idle, normal and full throttle).

 

Is it possible to adjust the IAC on my own or must be done by the dealer. Also that is not a bad idea about the pc3 but what about the program that is on my oem pc does it have the map or update for cams or is it just programmed through the pc3 ?

 

The stock ECM will not have your modified map, however, if it starts, then the PCIII might be an area to investigate.

Good Luck

 

Why not go back to the dyno? that way you know the a/f is right and you can rule that out. As a bonus, she'll run better as you already know.

 

Try removing the PC3. Do you have the download, or are you just useing the PC3.Personally I prefer the race tuner the algrythyms for the maps are muchmore complex.
