RE: PCIII Slow start
Haven't gread ALL the posts, not enough patience! I've had my PCIII installed for a month now. Bike runs great, and I don't have any of the delayed start issues. My bike is a 2000 FLHTCI with MM EFI. Maybe I've got a newer PCIII, or maybe the MM EFI doesn't have these issues. Who knows?

RE: PCIII Slow start
that makes perfect sense.. on my 06 roadking i MUST have the bike running to set throttle position....because like the instructions say some bikes do not keep the pc111powered up for any more than a few seconds after turning on the ignition.. you can tell because it goes thru its test mode and then the lights go out..untill you actually start the bike..this would explain why the bike has to be running to set t/p and would also tottaly explain the starting delay..wonder if just for a test, a guy could leave the 9volt addapter connected and see if it starts rt away..hmmmmmmm

SB..do I sense an attitude? Or is it that you work on these things and you assume we don't so your answers are correct? That's all good if that's the case. Please read the below OBSERVATIONS carefully. We are discussing a power loss issue during start up that is causing a delayed starting condition. I agree that power is present during cranking and normal running but I have observed an obvious power loss condition:
I simply made an observation and reported it on this forum. When the check engine light goes out I have OBSERVED severalthings happen on my bike: The check engine light goes out, I hear a relay trigger (which would indicate a circuit has either been energized or power/signal removed), the fuel pump stops and the LED's on the PCIII go out.
When I hit the starter button the fuel pump starts up again and the LED's on the PCIII begin to flash back and forth indicated that it has once again powered up. Once the LED's on the PCIII stop flashing the bike will start. Too much noise at this point to tell if the relay triggered again. I'll bet it does.
To prove my theory based on my observations I hooked up a 9VDC battery to the PCIII so the PCIII would always be powered. Guess what? The bike started immediatly, NO DELAY.
What does this tell me? It tells me that the PCIII loses power after the check engine light goes out. It also tells me that the PCIII is not passing signal until it has completed it's selftest. It also tells me that the PC folks need to rewire this thing so it does not lose power.
I am 100% confident in my observations and conclusions. Also please remember that after the delay was first noticed I found information provided by the Power Commander folks that some bikes may have a delay in starting after this device is installed. I will make an effort today in posting that information.
I welcome anyone to duplicate these conditions. If still in doubt come on over so we can OBSERVE together.

You a Tuner????
You have installed these on what, 50-100 bikes and tuned them.....
Didn't think so.....
You tell me, how is the power dropped after the CEL turns off......
It is always powered, wether it is while the CEL is on or off, there is a minimum of 9vdc going to it during cranking.....
I have installed enough of these POS' and tuned them to know and understand them..... That is why I like the SERT, no "Interface" issues, additional harness' to tuck away, and no software problems..... A better product, more capabilities, and a FULLY operational Diagnost Mode....
PC's are antiquated, and rely on Throttle Position and Engine RPM to control the AF ratio.... It's called Alpha N, and it is great for Drag bikes, but sux on the street....

I have to agree with gabhart on this one. I've noticed that I can't even get the PCIII to communicate with my laptop if I turn the ignition on w/o starting the bike. It goes through the self-test and it sounds like when the fuel pressure relay picks up, I lose the lights on the PC. At that point, I show no map loaded and the PC not communicating. Go ahead and start the bike and I get power back to the PC and see my map. Makes you wonder if they mis-wired this thing and it's powered off the wrong source.

I have been starting my bike in the manner that has been talked about for 2 years now. Just let the fuel pump prime for a second or 2, hit the start switch and it will fire right up. Its just second nature to me now and a non-issue. The light does NOT have to go out first before you start the bike.

RE: PCIII Slow start
Since putting the PCIII on my bike I have notice the slow starting as well, if I let the light go out. After reading this forum and starting the bike before the yellow engine light goes out it fires right up.

that makes perfect sense.. on my 06 roadking i MUST have the bike running to set throttle position....because like the instructions say some bikes do not keep the pc111powered up for any more than a few seconds after turning on the ignition.. you can tell because it goes thru its test mode and then the lights go out..untill you actually start the bike..this would explain why the bike has to be running to set t/p and would also tottaly explain the starting delay..wonder if just for a test, a guy could leave the 9volt addapter connected and see if it starts rt away..hmmmmmmm

Anyway fathertime, I did try this with the 9v battery attached and it indeed started right up.
