Default Zero position throttle sensor

For all you folks that have recently put on a PCIII. I put on that package deal from FuelMoto during Christmas and it runs like a freight train, lots of power, pulls hard, sounds good, all that I could ask for.

But...my fuel mileage was in the pits, so I called FuelMoto and they asked if I had reset my throttle position, I said no I haven't. They suggest I do, so I did. He said that if you don't reset, the fuel table could be off through-out the RPM band and that would throw off mileage. FuelMoto says they're getting about 38-42 MPG with their setup on bikes. (I was getting 31-32)

So, I suggest you set the throttle position whether you think your PCIII is close enough or not. Mine was a fair amount off, according to the displayed numbers.

Beware, if you look in the PCIII manual in throttle setting the procedure is a bit different than what you have to do. The ignition MUST be on, don't just use the 9V adapter, if the ignition is not on, the PCIII will not read the bikes info. (I was on the phone with FuelMoto at this time, because the 9V wouldn't do it)) Before I tried with just the 9V hooked up to the PCIII and the readout would not show throttle position when you rolled on/off the throttle.

When your laptop is hooked up to the PCIII and the program running, turn on the ignition of your bike, the current map will display. Click on POWERCOMMANDER TOOLS drop down meneu on top and select "set throttle position". A window will show up in your screen, there will bethree displays, one with"closed", "current", and "open" position. Click the "reset" button with throttle closed(this is step 4,5,6 in the manual for reset throttle) after clicking "reset" click the "<" button to the right of the "closed" window. Then open andHOLD the throtttle open then click the ">"button to the left of the "open" window. This will reset open and closed positions. Then clock "OK" button and you are done.

You can confirm by twisting your throttle open with the ignition still on and watch the throttle display go to 100.

This procedure in the manual if first read (as I inderstood it anyway) is not explanatory enough. To me, it left a few steps/explanations out. So, thats why I called FuelMoto and they helped walk me through the procedure. He was very helpful in explaining and getting me through this. Once done its a fairly simple task, I thought it just dont work that way straight form reading the instructions out of the manual though. But then again, I'm probably not the sharpest tool in the shed either.

Hope this helps some of ya'll, A little longwinded, but hey, its early Sat morning.

Ride safe.

Thanks for the info. Thank god they changed the way it is done. Used to be you had to open the throttle wide open with the bike running and warmed up. Sure, you just basically opened it wide open and quickly closed it running. But if you did it too fast it didnt workand if did it to slow you had a screaming enginewith the bike on the side stand. I always thought that was a really screwed up process. Glad it has changed.

its a bit easier than the old way, but I would have thought they would be more specific in the instructions. It was a little confusing to me, until FuelMoto talked me through it. I have read posts that folks say you can't have the 9v on and the ignition on at the same time. FuelMoto said it wint hurt anything, but I unplugged the 9v just to make sure, and used only my igintion "on"

To friggin cold today to test, (well, a bit of lazy too) I did start and run it and it sounded fine. Maybe later I can steal a quicky to test, I'm still gettin over a chill when I rode home the other day. It got colder in the afternoon then it was in the morning, I was sort of unprepared. (didn't wear my lower longjohns)

One more thing, if you do the 100% with the bike running, which you can, it will throw a code. Make sure and clear it. Not sure if it will throw the code without the bike running.

nope, no code, it did good on the start-up and revving in the driveway, gotta get out on it though, maybe later. 'Sposed to be about 45 degor so. But I gotta bunch of things (honey do's) to do before I go. Plus we're going to Rebas' and Kelly Clarksons concerttonite!!!after wifey gets off of work.

I don't know about the fuel economy yet, gotta ride it for a week (or tank) and see if it helped. Maybe this week, not supposed to be to bad, mid 40's to 50's (daytime high). I should be able to see this week. As long as it don't get into the teens in early a.m., thats a bit much for me, most of my ride is highway (split four lane) and the hawk (wind chill) starts gettin to me.

Just curious! When at zero throttle, did the values on the PCIII jump up and down? I saw this with my previous bike.

I killed my PCIII after I installed it by trying to update the firmware which was a older version out of the box. It was my fault because I missed one step in the instructions. Had to call tech support a few times and then send it back for repairs. In the process, the tech admitted that the instructions were less than perfect.

Setting the throttle position was a simple matter although once again the instructions could be better.

glebo, thanks for posting this. I installed mine a couple weeks ago and didn't do the 0 adjustment. bike idles a little high - about 10 mph idling along. step daughter had a puter die, so wepicked her up a laptop last week. first program on it was powercommander figure I'll play with it this next weekend. anyway, your take on instructions is clear enough for me to go for it. thanks.
