Need help on vr sensor sync lost

[julian944]

Hi guys,

could you have a look at my tooth log? I've really strange sync lost. The car runs fine, as long as oil and water is not hot and I don't rev it all the way to 6500rpm. Once it started I've problems in the rev area between 1000-2000 and 6000-65000. Is it possible that the vr circuit is sattureted because my vr sensor voltage is very high (more than 150V).

Log is available here.

Any help appreciated.
Thanks julian

put a 10k 1/4w resistor in series in the positive crank signal, if then you can't get cranking rpm try a lower value of the resistor, and make a composite log if you still have problems.
