Hello,
I like to make things right and I just checked timing of my Miata NBfl with timing light. Its slightly off about 2 degrees retarded (-> Fixed/Locked Timing ON set to 10deg). So I came to trigger setup and changed Trigger Angle from 0deg to 2. nothing happened, timing light shows still the same timing.
Changed Trigger angle up to 20 deg and still nothing (=2 deg retarded). Then started lowering from 0 to -5 (nothing) but at -10 engine started to run rough. Back to -5 or 0, engine works ok again but timing still retarded as it was
Tried to switch off engine, reboot Speeduino - no change
Tried with Fixed Timing at 0 - no change
switched off Trigger filter - no change
switched off Resync Every cycle - no change
What am I doing wrong?
timing light triggered using clamp on ignition wire
