Changes by last author:

Added:
Engine starts only with reverse crank sensor polarity.

* reverse of the factory?

* or reverse compared to what should be good ?

**reverse of the right polarity, VR sensor signal is rising. ( in this case I won around 10 degree of advance)

Added:
***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.
Changed:
The LCD and Megatune shows around the right RPM during cranking.
The LCD and Megatune shows the right RPM during cranking.
Changed:
When I try to positioning ign_tdcdelay, I get only 3 possibility erratic crank angle (measured by strobe) as I change the value:

*BTDC around 80 degree

*ATDC around 10 degree

*ATDC around 100 degree

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

It's looks OK, but if I use the right crank advance (8 degree through the crank),then get spark BTDC 70 degree again.

I can't make spark between BTDC 70 degree and ATDC 2 degree.

I do some measurement by scope with 15kOhm pullup to +5V on secondary trigger (both sensor conected with the right polarity) :

[Ignition ON]

[Ignition ON & cranking]

[Scope screenshot for details]

Cranking around 210-220 rpm

CH1 - cam signal

CH2 - crank signal

These are looks good for me, but I'm not sure of course, because the problem with the spark advance is still the same.
