I INSTALLED PCIII WITH 2 BRO M2 SLIPONS, K & N FILTER W/ BOX MOD. ALL WENT WELL AND FIRST RIDE WAS VERY GOOD IMPROVEMENT. I ONLY TOOK SHORT RIDE AND HAD TO WAIT DUE TO WEATHER FOR NEXT DAY RIDE. I TRIED TO START BIKE AND NO GO, HEAVY FUEL SCENT, IT WAS COLD NIGHT BUT NEVER HAS MY BIKE NOT FIRED RIGHT AWAY. THE PC WAS MAPPED FOR MY MODS. I HAVE SEEN POST ON SOME SENSOR NEEDING TO BE UNHOOKED. ANY HELP APPRECIATED BEFORE I UNHOOK PC AND START OVER?

make sure you have a good ground on the wire coming from pciii i hooked mine right to battery had similar problems.

From my esperience it may be putting too much fuel into system. Mine would start, but then cut out. I went through so much gas and it would cause my number 1 cylinder to flood out. You can try working with the 3 buttons, especially the first button, but more than likey you have a faulty PC unit. It would work ok for some time, then add a passenger, then it would flood out.They say zero map the unit, but I think if you take it off, you will see the bike works fine.The other thing is how long did you have tank off for? Maybe it starved. But then mine was hard to start after I put on and gave me much headaches after untill I finally yanked of. I almost even bought new coil stricks thinking they were bad.

Take it off and then see.
