Cossi Triggerpage
Primary tigger:
- 665 Ohm (with sensor disconnected)
- 148 mV (with sensor connected, ignition ON, not cranking)
Secondary trigger:
- 817 Ohm (with sensor disconnected)
- 0 mV (with sensor connected, ignition ON, not cranking)
- NO pullup: might be very sensitive during cranking. 10..22kOhm pullup to +5V might help
- Tried, but nothing changed. The same result with 10-15-20kOhm pullup to +5V. We get good rpm values, but so far I can't adjust TDC with the ign_tdcdelay value.

The LCD and Megatune shows the right RPM during cranking.
When I try to positioning ign_tdcdelay, I get only erratic crank angle (measured by strobe) as I change the value:
(ign_crank_advance=01 ,crank advance 0.25 degree)
- ign_tdcdelay=C8 (100 degree) the timing light shows ATDC 10 degree
- ign_tdcdelay=A4 (82 degree) the timing light shows BTDC 70 degree
- ign_tdcdelay=AA (85 degree) the timing light shows ATDC 2 degree
I can't make spark between BTDC 70 degree and ATDC 2 degree.
