I wonder what has changed between
https://rusefi.com/forum/download/file.php?id=5241 and
https://rusefi.com/forum/download/file.php?id=5273
both file names say "no inverted" and the older one show proper engine cycle.
Also lower "engine sniffer size" or zoom-in would show things a bit better, as is narrow gaps on the signal are just too narrow.
Just to confirm that you have saved ECU settings & rebooted ECU between each inverted/not inverted setting change. Worst case scenario this could be messing things up.
As for bigger resistor value, I am not sure why would your car ask for a higher resistor value comparing with my VVT - sensor part numbers seem to be the same. But technically as a short-term solution you can take two or three 5K resistors and make yourself a 7.5K or 10K, but this is shooting blindly since no one needed above 5K so far and we do not have oscilloscope to confirm that's the issue.
At this point I am pretty confused
I am playing with simulator
NB1
set engine_type 9
NA
set engine_type 41
NB2
set engine_type 47
and looking at
https://rusefi.com/wiki/index.php?title=Manual:Software:Trigger#Mazda_Miata_NB1
and I am only getting more confused.
If timing light confirms proper timing advance with one or both channels inverted maybe I am mistaken about something here
Maybe best to leave things as is if it works.
Do you get sync warning / error counter going up with 5K revving? Can you please post a log of failed 5K revving?
