Im in the US, so vehicle modifications are not really regulated. Ignition modifications are not regulated in any way.
My insurence will consider it a "electronic anti-thift device" and reduce my insurance premium.
The way the system works at this point.
The controller is powered by the 12v battery with a 5amp fuse.
When my fob is within 10ft(3m) of the bike, the controller sends a .3sec 12v "unlock" signal to relay 1 (latching), then closes relay 3 and then powers the bike.
Pressing the brakes puts the controller into sleep mode.
When the fob leaves the 10ft (3m) area, a "locking" .3sec signal is sent to relay 2, then unlatchs relay 1. Opening relay 3 and powering the bike off.
After 2mins of the fob out of the area the controller goes into sleep mode. To prevent battery drain.
I choose to use a 12v/40amp 5pin relay because they are available everywhere here. If something were to go bad in the system, i could pick up a replacement very easily. Is too big of a relay going to hurt the system?
The only reason i wanted to keep the ON postion. My bike has to be in the ON postion to do onboard diagnostics.
Could i keep the keyed switch in the circuit, but leave it on the RUN postion, at all times, and have relay 3 wired on the ground side of the switch and contol the power of the bike. Would keep the right resistance to the ECM, also preventing voltage spikes from reaching the ECM? Then I could switch to the ON postion when needed?
