Yeah, saw that!

Saw all webinars on ref/sync yesterday, and ready to test more today. I have been thinking that the cirp and index tooth was the same thing. My bad, thanks for pointing it out.

It started!, But died (time for fuel settings).

Turned the motor over to the index tooth. Adjusted the sync trigger plate to 90deg in front of the sensor (180 crank degrees).

Turned the motor to TDC1, counted 16-17 teeth back to the sensor. 60-2 wheel = 6deg pr tooth. CRIP = 6x17 = 102deg.

Removed spark plugs, got nice trigger pattern.
No errors after readjusting the volt filter from yesterday.

CRIP was nowhere near the previous ECU (m48) setup, how is that possible? CRIP was 638 before, we have not touched the trigger wheel during the swap.
So much for trying to save time by transferring settings :p

Actually, the CRiP number is only 20degrees different, if the number was 618 then they would be the same, just calculated in a different direction.
