hi I'm Chris from Dynojet and thank you for tuning in in this video I'd like to
talk about the optional speed and gear input features of the Power Commander V
for years the power commanders always use two basic inputs to calculate a
corresponding output to go to the fuel injectors throttle position and rpm but
with the expansion capabilities of the Power Commander V we now have the
capability to bring in a couple other signals such as manifold pressure engine
temperature speed or gear this video I only want to talk about the speed and
gear options the speed signal input can be used to view live vehicle speed on
the pod 300 digital display accessory or you might want to see live vehicle speed
in the Power Commander software this input does not change the calibration of
the vehicle stock speedometer in any way if you have a Power Commander 5 with
ignition control or even the ignition module add-on accessory for the PC 5 you
might want to use the pit lane speed limiter function and that feature
typically uses a speed input the main reason for bringing in a speed signal is
to also bring in a gear signal if the power commander 5 can see the vehicle
speed and the engine rpm it can find out what gear you're in based off the ratio
of those two gear inputs can be used to change the fueling or the timing
differently in each gear you might also do this if the rider has a preference
for the vehicle to run differently in each gear another good reason to bring
in the gear input is to use gear dependent quick shift or kill times if
using a quick shifter you can change the kill time differently for each gear
you're shifting into and also the power commander will not trigger a quick
shifting event if it already detects that you're in top gear on some vehicle
models such as Harley Davidson we actually make the hardware connection to
the vehicle speed sensor and the main harness of the power commander 5 but in
most circumstances you'll need to actually wire
this signal input into the Power Commander 5s wire terminal strip you can
use at 22 to 24 gauge wire to tap into the stock vehicle speed signal wire and
then run the other end of this speed signal wire into the wire terminal strip
of the Power Commander V specifically that is the third hole from the outside
edge or the fifth hole of counting from the middle for model specific enquiries
and or to see if your vehicle is compatible with the speed input please
give us a call or shoot us an email if your vehicle does not have a compatible
vehicle speed sensor signal you might alternatively input gear
position from an analog gear position sensor signal this would need to be a 0
to 5 volt analog signal you would tap a 22 to 24 gauge wire into the signal line
of the vehicle and you would run that other end into the wire terminal strip
specifically the analog input of the PC 5 wire terminal strip is the 2nd hole
from the outside edge or the 6th hole if counting from the middle once you
physically wired the signal input you'll need to calibrate this signal in the
Power Commander V software and this is typically done on a dyno or on a sinner
stand where the vehicle's rear wheel can spin freely go to power commander tools
calibrate then speed input
this will bring up the speed calibration window we need to enter a target speed
we typically recommend 30 to 40 miles per hour for this example I'll use 35
the left software window is our dyno software showing our actual dyno drum
speed all I'll need to do is hold the rear wheel spinning at 35 miles an hour
and once the dyno is telling me that I'm at 35 miles an hour I'll click calibrate
and that'll set my scalar value once the scalar value is correct you'll notice
that the speed gauge in the Power Commander V software matches that of the
dyno software now that the speed signal is calibrated I'll click OK for the
speed calibration window now I can calibrate the gear input based off of
gear ratio I'll go to power commander tools calibrate gear position here in
the gear calibration window I'll need to make sure my source is set to gear ratio
then while holding the bike in first gear at about 3000 rpm with the clutch
out and the rear wheel spinning I'll click the calibrate button for 1st gear
then I'll ship to second and do the same for second gear typically holding an RPM
of 3 to 4,000 I'll do this for all 6 gears after I've calibrated the gears
I'll click OK and I'll notice the gear gauge in the Power Commander V software
will show the true gear that I'm in if using an analog gear position signal
make sure the source setting in the gear calibration window is set to voltage
then click calibrate for each gear while simultaneously running the engine in
each specific gear the wheels do not need to spin for this type of
calibration you can typically do this while holding the clutch in and cycling
through the various gears if you still have any questions about either of these
inputs please give us a call or shoot us an email
