Hi
l have problem with the rpm sensor/ trigger wheel. It show a rpm of 2500-3000 when the engine idle at 1800-1900 rpm. so about 1000 rpm wrong.
l think the problem is the trigger wheel l have made. see picture below
If l make a new trigger wheel , what should l change ?
Outer diameter so distance between teeth will be wider and maybe also wider teeth?
best regards

thank you 😊
OK, engine brake, then 12 teeth is fine.
Yes, you put 12 pulses per revolution. But for an engine dyno, the gear ratio is 1, unless you have a gear box. So for Engine RPM source, you select "Set gear ratio manually". Set it to 1 and it should be fine!
yes it is a engine brake!
pulses per revolution is set to 12 , that must be correct?
under the tab gear ratio setup l have the settings as picture below.
maybe someting here iS wrong?
That wheel should work. Not a lot of teeth though, is this an engine brake? Check out this link
Otherwise two possible causes:
- You have not set the Number of pulses per revolution correctly
- Gear ratio is wrong
