Altitude Setting
If your engine is carbureted, you can adjust the elevation
setting of the Polaris electric reverse control (PERC). If
your engine is a Cleanfire system, this is automatically
done through the engine controller unit (ECU), and you do
not need to do any setting.
At higher elevations over 600
0 feet (1829m), the engine
requires a different ignition RPM setting to improve the
operation of the reverse system.
To set the altitude settings:
1. With the engine running, push and hold the reverse
bu
tton for 5 - 6 seconds and then release the button.
2. The reverse light will flash rapidly on the ins
trument
panel.
3. You have now set the PERC system to the higher
e
levation setting.
4. To go back to the low elevation setting repeat step 1.
The revers
e light will flash slowly indicating that the
system is now in the lower elevation setting.
NOTE: Th
e elevation setting will be set in the
memory (engine running or not) until it is changed.
Important Notes
• Max RPM for shifting into reverse = 4000 RPM
• Max RPM for operating in reverse = 6000 RPM
• Engine must first reach 900 RPM at start up before
the r
everse system can be used. The system
works between 900 and 4000 RPM.
• If the button is pushed above 4000 RPM the
sy
stem is bypassed and nothing will happen.
• Flashing light on the instrument panel indicates
that th
e system is in reverse. On carbureted units
a slow flash indicates that the system is set for low
elevation, and a fast flash indicates the system is
set up for high elevation. Push and hold the
reverse button for longer than 5 seconds to toggle
back and forth from high and low elevation
settings. On Cleanfire units this is automatically
done through the engine controller unit (ECU).
• Elevation above 6000 ft (1829m) requires a
dif
ferent timing curve to eliminate a “kick-back”
effect.
• If engine is shut off or dies in forward or reverse
gear
, the engine when started will automatically be
in forward gear.
• When servicing clutches, ensure that the vehicle is
in
the forward gear.
• On DC-CFI models the PERC system will not
o
perate if the TPS is out of adjustment or the 5
tooth CPS signal is interrupted or broken.
