Jag har min ikopplad och kör på både 95 å 98. Märker ingen skillnad mellan oktanen.
Kontakten ändrar motståndet (ohm) i ECU:n.
I runda svängar tycker polaris att man ska ha den ikopplad för 98 och urkopplad för 95 oktan.

Your 2009 Polaris Snowmobile has been equipped with a feature within the ECU that allows you to select the proper calibration mapfor the fuel available in your regon. The machines listed above were produced in the "unplugged," or ethanol fuel mode.
IMPORTANT: it is imperative that the engine is not operated with ethanol fuel while the black/blue and pink wires are connected together or engine failure could occur.
The mode change wires are located in the wiring harness secured to the rear underside of the clutch guard behind the machine console. If in doubtabout fuel quality, always operate with the connectors unplugged.
Unplugged: Leave the wires UNPLUGGED when using oxygenated fuel containing up to 10% ethanol. Never use E85 blended fuel
Connected: CONNECT the black/blue and pink wires together when using non-ethanol blended fuel only!------------
