needforspeed - 26/12/11 at 01:18 PM

ok heres the trigger wheel on my 2008 r1 its 24-2 in the settings in the emerald ecu it asks for the degrees before tdc it triggers judgeing by this picture it looks like 225 degrees??? can someone help me confirn this!

should add the picture is of the engine at tdc on cylider 1 with the crank sensor at the bottom

Why way does it rotate?
If engine at TDC and sensor is at the position as drawn the the missing tooth looks to be 115 degrees ish.

That's great thanks it rotates clockwise

The missing tooth is recognised then 9 teeth later the crank reaches TDC
360 degrees = 24 teeth
180 degrees = 12 teeth
90 degrees = 6 teeth
Sensor is 9 teeth after TDC which means sensor triggered 135 degrees before tdc
