EJK controller plugs into the fuel injectors and the temp sensor.
The YELLOW/BLUE mode controls the voltage offset of the temp sensor which can be used to indirectly subtact fuel from the
snowmobile. A setting of 0.5 is like running on the stock ECU map. A setting of 8 will result in the largest voltage
offset of 1.2 volts allowed by the tune-up.
The GREEN zone engages at 3900 rpm with a GREEN/BLUE setting of 4.
For ’07-‘09 F/M8’s & Crossfire you must re-pin both, unplug the factory injector connector
off of the PTO injector. Next you need to remove the connector’s pins by taking a small pick
type tool and from the front of the connector gently pry up the pin’s locking device (see figure
2) while at the same time gently pulling on the corresponding wire. (See figure 3) Repeat on
remaining pin and MAG injector. Then reinsert the Green/Red on the LH and Green/Black
RH PTO. (See figure 4) MAG connector yellow/red LH and yellow/black RH.
