How does the ECU know what gear the bike is in?

[bloodline]

so, we know power is restricted in the first 3 gears. What tells the ecu what gear the bike is in?

The ABS signal (blue wire) from the rear wheel is fed into the ECU.

If you tap that wire and feed it to the PowerCommander V (if you have fitted one) you can have a map for each gear.

I guess this is the same wire you need to tap into if you want a gear indicator?

Short answer is it's calculated within the ECU using engine speed vs wheel speed. No easy ways to fool it. That's why the power restriction thread focuses on the various reflashes avilable...we've already been down that road.

Yes, it is the same one you tap into to connect gear indicator, also the SpeedDRD.
