Exhaust motor valve start check disabler for Monster 1100

Only for Motorbike equipped with  DP ECU map installed a way for disable and unmount exhaust motor valve.

This circuit is not usable with original ECU!! In that case you can disconnect the steel wire near the valve :-).
This circuit deceives ecu only at key ignition start-up, in fact with dp map after ignition the motor valve would not be operated anyway.

Calibration

There are 2 state must be calibrated in the circuit or rather with Relais open and closed.
To calibrate open state of relé act on R3 so that voltage in J1 Yellow be about 1387mV.
To calibrate close state of relé act on R1 so that voltage in J1 Yellow be about 3,39V.

 

That’s all, enjoy !
