I was just outside starting the 1125r several times in a row (trying to reset the historical codes) and it threw an IAC error (live) and the CEL came on for a few seconds.

Any ideas about what would throw an IAC code in that condition?

I also noticed that the Front and Rear O2 sensors have different voltages before start up but show (aproximately) the same variable voltages running. I also noticed the TPS flutters between 2.0 and 2.5 when idling.

Just curious. It's going in for service on the 3rd so I'm sure it'll get sorted.

Thanks in advance.

Mine has a whole host of error codes since fitting the Erik Buell Racing ECM but i'm hoping after a load of starts they will all get erased

Nah this is on the stock ECM. The codes on the Erik Buell Racing are just from them programming the thing without an actual bike (and all the peripheral stuff). My Race ECM did clear after a number of starts. I've heard it clears after 50 starts but it sure seems to take more. I just wanted to clear out any codes on the stock ECM before I turn it over for service Tuesday.
