Calibration of Power Commander TPS
02/07/09 12:34 PM

Here is another HOW-TO post from the zx14ninja.com forum. It was made by Raptor14 on 7/22/2007.

For those of you installing Power Commanders, don't neglect to calibrate the Throttle Position Setting using the Power Commander software. I know a few guys who did not do this. In addition, I recently rechecked mine and found that it was not set correctly. Not sure if I screwed up the first time, played with a map and forgot to calibrate it myself, or if something changed. After calibration my decel pop was significantly reduced and in some cases didn't occur at all. Further the part power throttle response seemed to be slightly better. For those who don't know how to do this, you need to plug the PC into a laptop. You can only set the TPS when it is on the bike. Here's my procedure:

1. Plug the PC into the laptop. Install the 9V battery to power up the PC.

2. Start the bike and let it warm up and reach its normal idle. If you try to calibrate the TPS on a cold engine you will get an incorrect calibration. At this point the PC will run without the 9V battery but leave it there. It will be necessary later.

3. Open the Power Commander software. If the current map is not downloaded and displayed automatically select GET MAP.

4. With the map displayed select POWER COMMANDER TOOLS > SET THROTTLE POSITION.

4. With the bike running and the engine at idle push the "<" button to set the 0% throttle to the value read from the bikes electonic signal.

5. The following 3 second rule may or may not be applicable anymore but I still use it. You can do as you wish. Perform the following actions, in order, in a 3 second period: (1) turn the engine off using the kill switch, not the key, (2) with the engine NOT running fully open the throttle, and (3) hit the ">" button in the Dynojet software display to set the 100% throttle position to the value read from the bikes electronic signal. To insure that the Power Commander is working you have to have installed the 9V battery.

6. Start the engine and verify that the TPS readout in the DJ software is 0% at idle and that the rpm display is matching that of your tach. Turn the engine off and open the throttle fully. Verify that the TPS readout is now 100%. Close the throttle halfway and verify that the TPS readout is 50%. You are now good to go.

Note that the fuel map is a function of rpm and throttle position. If you have not calibrated the throttle position you may not be running the fuel adjustments as intended by the map.

Good post! I have seen on the old board where a lot of people try to do this with the motor running (knuckleheads) and this scares the crap out of me, although it does test the rev limiter, and the connecting rods, crank, etc.

If you use Ivan's maps, you need to set the TPS as follows (per Ivan). Easy Hub.
Use a buddy or family member to watch for the 100%, that way you can concentrate on snapping the throttle back.
It does make a difference how you do this. % throttle open on your bike must correlate with % throttle open on the map or it throws the whole map off.


Setting The Opening & Closing Points On Your PC3


1) Boot up computer, load the power commander software…
Select PC3 USB and do the install, when finished remove the CD.

If you cannot get your bike to communicate with the computer….
Call dynojet (it’s their software& product)

2) Warm up bike to 170+

3) At the top of the screen, click on Power Commander Tools, and select Set Throttle Position, a dialogue box will open with 3 sets of numbers starting from left to right they will be “closed”, “current” and “open”

4) Set the idle on the bike so that the average idle speed is appx 1250 - 1300 RPM on the computer screen
(and this is where it’s going to stay)

5) In the Set Throttle Position window look at the “current” number for a few seconds
(this number will be changing, so you need to pick an average)
after you have selected your number, write it down, and change the number in the closed box to the number that you have selected and press the “OK” button. After you press “OK”, the box will disappear.

6) Looking at the throttle position readout and the rpm, gradually apply the throttle…. You want the “0” to change to a “1” between 1650 –1700 rpm
(for my map).
If the throttle position readout value does not change at the correct rpm, go back to “power commander tools” and “set throttle position” and change the value by 20 points and try the throttle test again until you get it to change from “0” to “1” at the specified rpm.
(A higher number will give a higher rpm before it changes)

7) Moving on to set the “open” throttle value…. Got back to “power commander tools” and “set throttle position”

Please read and understand this before going any further…

During this procedure the key cannot be turned off….

You will be stopping the engine using the kill switch on the handlebar….
and after it stops, immediately put it back to the “run” position….
Then hold the throttle wide open....

While the throttle is open, read the number in the “current” box and write it down
(it will be greater than 23000)

You have to be quick with your hand movements doing the off/run/wide open, otherwise the software won’t give the correct number in the “current” box. (Obviously the bike is not running when you do this)

After you’ve written the number down, restart the bike and replace the number in the “open “ box with the new one…. And press the “OK” button.

8) To verify that the “open” value is correct…

Watching the throttle position readout on the screen, and with the engine running, pin the throttle to the stop and release it

(don’t be an idiot and let the engine hit the rev-limiter)

the display should momentarily display 100%
Try this a few times to verify... if it does not give “100”

If it says “99” try reducing the “open” value by 50 points at a time until the display gives you the 100% when you pin the throttle.

Once you have the open value set, you are done.

I still prefer to walk everyone through this who buys a PC3 from us.

Please do not call me with questions about this procedure…

If you call, please be ready to follow my instructions without any questions…. We will just breeze through it, and get your bike set up.

Ivan

i know old thread but.... on my 2011 14 with a pc5, the bike must be running in order to calibrate the throttle.

if the bike is on but not running, the sensor voltage will not change. bike must be running.

rev the bike to redline once while in neutral and it will calibrate
