Q: What if there is
no specific map available for my combination?
A: Please read this file for additional information on selecting a map

Q: When I try to communicate
with my Power Commander I receive the error "File and Power Commander
versions incompatible". I know that I have chosen the correct map for my
bike, so why is this happening?
A: The main reason for this error is having the incorrect "Com"
port selected. On Power Commander software versions prior to 2.7.7.3 it was
possible for the software to auto select the "Com" port that the modem
is on. The software would then try to communicate. Since there is not actually a
Power Commander attached to that port the "incompatible" error is
displayed.
On the latest version of software this has been
addressed. Download it
now.
To correct this problem in previous versions of
software do the following.
1) Connect the cable to the Power Commander and to the
computer
2) Switch the bike's ignition on and make sure the kill switch is in the
"run" position. The light on the Power Commander should be lit.
(as a side note, GSXR1000/600, Triumph, and Aprilia models must either be
running or have the "power up adapter" installed in order to
communicate with the software).
3) Make sure that any other software that uses the 9 pin serial port, such as
Palm Pilot, is shutdown.
4) Open the Power Commander software.
5) Click "ports" then select "Com1".
6) You should now have communication. If not, do step 5 again but select
"Com2" through "Com4".

Q: I plug my Power Commander into my
Harley and it does not start, but with just the stock ECU it starts fine. Is the
Power Commander defective?
A: We have found in most cases that the crank position sensor is
defective even though the Harley "Scanalyzer" shows that it is good.
The PCII needs a near perfect crank signal to work properly. The bike may run ok
with a sensor that is marginal, but over time the performance will degrade and
eventually the bike will not run.
Q: I took my Twin Cam 88 to the
dealer to have it serviced. When they plugged in the Scanalyzer (HD shop tool)
it would not recognize the ECU (electronic control unit). Did the Power
Commander II damage my ECU.
A: The Scanalyzer will not work correctly with the Power Commander II in
place. For diagnostic work that needs to be done using the Scanalyzer, the Power
Commander II needs to be disconnected for the duration of the testing. Also, the
Power Commander II is internally fused. If a short circuit did occur the fuse
would blow before any damage could be done to the ECU or the sensors.
Q: Occasionally when I start my
bike the engine light comes on, then goes off, then comes back on again for a
few seconds then goes out.
Is this a problem?
A: This is not a problem. Disconnecting and connecting your ECU may trip
a trouble code. When the check engine light comes on after start-up it means
that a trouble code has been tripped, if it goes back out it means that the
problem is not occurring at the moment and the code is stored as a historic
trouble code. Historic trouble codes clear themselves after 20 starts.
Q: The message "Com port
opened, but Power Commander not found" comes up on my interface. What does
that mean?
A: The software is not communicating with the Power Commander. Make sure
that the ignition switch is on, the kill switch is in the run position, and the
serial cable is firmly connected to both the Power Commander II and the
computer.
Q: When I type in 15 in the
ignition table, it changes to 11 by itself.
A: The maximum timing allowed is +/- 11 degrees. If a value is entered
that is larger than +/- 11 the software automatically reduces the value to the
maximum allowed.
Q: Why can I not adjust the
timing at 2000 rpm on my Suzuki?
A: On Suzuki models timing changes can only be made from 4000 rpm and up.
Q: File and Power Commander
version incompatible error appears when I try to load a map.
A: This message will appear if you try to load a map from a different
make or model than the Power Commander II is connected to. (i.e. attempting to
load a Harley map to a Suzuki).
Q: I have installed the power
commander software from the CD but I cannot find any maps.
A: The maps are stored on the CD-Rom in a directory called maps. You can
either: [1] With the Power Commander software running, select File from the top
drop down menus, then pick the load map file option. This will bring up the open
file window and you can select the CD-Rom drive and directory in the top menu
box. [2] Run the Dynojet CD-Rom and select the map tables option. In the top
window select your bike model and then highlight a map you wish to install. This
will show the associated map notes and selecting the install map option will
copy the map into your c:\pwrcmdr directory alongside the software.
Q: I want to alter the map in my
power commander but I cannot get my computer close enough to my motorcycle.
A: We offer a power up programmer module which allows the power commander
be programmed from the computer without being connected to the motorcycle. This
is available direct from Dynojet for $100. Part Number Description 76423001 110v
for US 76423002 220v for Overseas.
Q: The buttons on my Power
Commander II don't feel like they are moving.
A: Because of the special compound used to seal the units, the buttons
may feel like they do not move, even though they actually do. You can verify
that they work by going through the "How to adjust your Power Commander
II" procedure in your instruction manual.
Q: I have had my stock ECU modified with the YAFM
box. Will the Power Commander II still work?
A: The Power Commander II will work if you have your stock ECU reset back
to its original settings using the YAFM box.
Q: When I adjust by Power Commander II using
the on board buttons and then do a "get all" with the software I do
not see any changes to the map. Is this normal?
A: Yes, this is normal. While the buttons do adjust the fuel curve, they
do not write these changes to the ".map" file. As a side note, any
time the map is modified using the Control Center Software the buttons are reset
to "0".
Q: When I first start my bike (Harley only)
after it sits for a while it seems to run different than after I ride it for a
mile or two. Why is this?
A: The Power Commander II monitors engine temperature and only modifies
the fuel curve after the bike has reached full operating temp. This keeps the
bike from being overly rich during its cold start cycle.
