Cough/cut out when started.....
Bike, 05 Heritage EFI,seems to cut out/cough upon starting. Usually it will high idle for a few seconds, then to operating idle speed. Tonight, it really didn't high idle upon start up. It kinda just chugged a lil at a lower RPM. When the throttle was cracked a few times, it spit, coughed and cut out, like a cold Ford or a carbed bike on full choke when it's warm.The tank was just repainted, and of course the guts replaced. The filter wasn't because the milage isn't that high really, but I'm sure that one will come back to bite me in the a$$! Any ideas? Thanks, K

RE: Cough/cut out when started.....
The IAC motor is on top of your throttle body, it allows air to pass (measured in steps)the closed throttle plate so the bike will start and idle but if it isn't doing it's job correctlythe bike won't act correctly.
Now that you say you have a PC III on your bike sheds a different light on the problem....it's necessary to have all the informationyou can give when asking for someone to trouble shoot your systems. There was a problem with the FIRMWARE of the PC III that allowed the engine to hesitate off throttle and hard starting. You can go to your help menu in the tool bar of the program and see what firmware you have and then look on the Dyno Jet web site for the latest update....if your firmware doesn't match the latest version on the web simply follow the instructions on how to update your PCIII.
A quik test for you to do is unplug the PCIII and see how the bike acts....if it starts and idles fine then the PCIII is the problem....if it acts the same I'd say the IAC motor needs looking at.
Good Luck

Doc, do I need to have the PC hooked up to the computer to do all this? It seems the "update firmware" action is not highlighted when I just click on it without being hooked up. Thanks, K
