you can try using MAP sensor to detect engine phase

However high revs are likely a problem with extra spark in 4 stroke. It's likely to not enough time build a magnet field.

Have you set "individual coils" in ignition settings ?

And how is the cam sensor ? hall with or without pullup ?
Normally, motorcycle engine only use Crank Sensor.

Some engines are two stroke and some engines are four stroke.

On a four stroke engine crank position sensor does not know when to ignite.

How do you address that challenge?
I have 4-stroke 150cc 1-cylinder motorcyle engine with 12-1 Trigger pattern attached to the microrusEFI

The method I am hoping to use is running Waste Spark during Cranking and transitioning to Individual Spark when exceeding the Cranking RPM. If the RPM drops below the Cranking threshold it will return to Waste Spark.

Is there any way to currently do this? If not, I hope it may be a feature in the future.

or map sensor in case of odd-fire engine
I managed to implement 12-1 trigger on a single cylinder engine with individual coil ignition mode. Accordingly, four cylinders should be able to run on this mode. Does this feature exist or has it yet to be added?

Thanks for the help.

Without knowing engine phase engine is running in wasted spark mode.

Welcome to the forum!
I there a method to make it individual spark? I am trying to adapt the ECU for a motorcycle at high speed around 12k to 14k rpm.

Thanks.
