pcIII adjustment procedure?

I searched and could not find the answer.

I just installed Muzzys 2-into-1, Churchkey VBAK, AIS block and PCIIIusb. I am running Jimbomans map for the same basic setup except he has a Pro-pipe.

I checked plugs before starting and they looked pretty good, maybe just a touch lean,(light tan with some areas a little lighter on the ceramic). I switched out all plugs and rode 25 miles at normal speeds. I then came home and checked the new plugs and the ceramic was white - no tan or brown at all.

I then went up 4 steps on the button adjustments for low, mid and high on the PCIII. I then rode 4 miles and checked again with no visible change to the plugs.

Here's the question - How long is it safe to run in this lean condition and how long do you ride when making a manual change on the pciii? I am worried about causing damage so I did not want to ride too much until it is adjusted. Should I go 5,10,50 miles before seeing a change with manual adjustment on pciii?

I assume there are only five steps leaner or richer for manual adjustment. If that is not enough, how do you richen in the software for the pc111? Do you just go through each cell that is not a zero and increase the number by 1,or 2 over what it was?

Sorry for such a long question but I figured more info would make it easier to diagnose the problem.

Thanks for the help guys.

The change on plugs take miles many miles. I have the same map and have to lean it. Try the Darkstar map and compare results. Ask the Muzzy guys if they have a map for their pipe.One touch and you lean or rich that area 2%. If you have to adjust a map by 4 touches on a button try another map. If you want more gas on any area after that 4 adjustment them go directly to the map on your computer and sum + 8 on what you select to adjust. Save the map and tranfer it to the bike and start again with the external buttons. Every time you tranfer a new map or adjust the one you have using each cell, the PC111 reset the external buttons adjustment to zero. Good Luck! My next post will include the manual adjustment. Stay tune.

Hey Penzoil - thanks for the help. The plugs dont look bad, just the ceramic is still white with very little carbon build-up. As I said, I have only run it at normal riding speeds for about 30 miles. Is this not enough time to see from the plugs if the settings are right? I just didn't want to run too lean and screw anything up. What symptoms will be present if it is too lean?

I tryed darkstar's map but could not import it into the pcIIIusb program. I think because when I save target it is not the same file type. I also don't know how to unzip it. Do you have darkstar's map in the .map or .djm file format? If so, would you mind sending it to me?

Again, thanks for the help. I want to get this setup so I can take it out and ride tommorrow.

If you can connect your computer to PCIII on the bike, you can richen each cylinder via the cylinder trim function in the software. As long as the PCIII is connected to the computer, it is in the "power commander tools" drop down menu at the top. It is just like adjusting the "co" values on the ECU.
There is a good tutoria @ powercommander.com for converting old .map files to the newer .djm format.

good luck

To adjust a Power Commander to eliminate a problem in a specific area,say an off-idle or mid-range stumble, you must use the Control Center Software.To find the RPM the problem occcurs at you'll need a tachometer. To determine the throttle position where the problem occurs, wrap a piece of masking tape around the throttle grip. With the Power Commander plugged into the computer, the Control Center Software open,and the bike turned on (but not running)you can view the "Throttle Position" scale on the screen. (The Warrior is an exception)Roll the throttle open and mark the tape to match each of the Throttle Position columns (10%,20%,40%,60%,80%). This done, ride the bike and duplicate the problem, noting what RPM and Throttle Position it occurs at. As examples, if a problem occurs between the 20-and 40% marks on the tape,and between 3000 and 3500 RPM, you would adjust the four cells that control that area. In other words,use more than one cell adjustment to cover an area that falls in-between the cells. Good Luck!
