RE: PCIII Slow start
You have to hook up your PC to a PC (Personal Computer)....
In the PC Tools menu, Open the UTILITY and verify the current Version..... (Pretty sure that is how to do it)...
I am not in front of my Tech PC, and my memory is about as long as my schwantz, and that aint saying much......

RE: PCIII Slow start
well, i have a question,
most of my performance cars have fuel injection pumps with pressure regulators ,etc,which i assume is the same set up as the harley ???
and ,i wait until they stop whirring before i hit thestart button.
the reason is to give time to the fuel pump to fill up and get full fuel in the lines .
the suggestion made of pushing the start button on a harley before the light goes off ,i think, will overtax the pump, right ?,,or not ??
any experts on this topic out there

RE: PCIII Slow start
If you have delayed starting using a PCIII:
Watch the PCIII when you are starting the bike. When you turn the ignition on the PCIII will do it's selftest (LED's flashing back and forth) along with the bikes ECM/fuel injection. When the engine light goes out the fuel system becomes pressurized and power is removed from the system ALONG WITH THE PCIII (the LED's turned off on the PCIII, yes?). When you hit the starter button power is reintroduced to the injection system, ECM AND the PCIII. Since the power was removed and then reintroduced to the PCIII the PCIII has to go thru it's self test again thus causing the delay.
That's it in a nutshell.

RE: PCIII Slow start
gabhart,
Without owning a PCIII yet, your explaination makes the most sense. When I think of how the bike starts; after turning on ignition you hear the feul pump charge, then when you hit the starter the feul pumps fires up again. It makes perfect sense. Now if there was just a way to power the PCIII with a constant lead from the ignition without the delay and the problem would go away. Good job!

RE: PCIII Slow start
I agree with what Bob said.... In fact, let me go back & read my original post.....
Yea.... something in the MAP. Also the idea of firmware rev differences makes sense.
When I get a chance, I'll compare the MAPs & report back.
Mine works FINE, and my MAPs work fine on units that have the problem with fuelmoto MAPs.
That's all I have to say on this topic.
