Any strange behaviour, crashing issues etc, post them here! Problems compiling the firmware should go in the General support section rather than here

Hey guys...

I have a slightly crazy problem with my EU GA16DE. It has an optical CAS on the camshaft.
The trigger pattern is the same as the Daihatsu+1 decoder (4 large slots + 1 smaller one in front of cylinder 1).
The setup was without any major problems and the car runs really great without sync problems.
But in about 1 out of 10 starts, the engine suddenly starts shaking, running rough and has no power. It almost sounds like it is only running on 3 cylinders, which it is not.
If I turn the engine off and restart it immediately, everything runs fine again.

There are no abnormalities in TunerStudio at the moment when the problem occurs . There are also no sync problems or anything similar.

However, at this point I took my ignition gun in my hand and measured the ignition angle.
At this moment it is not at 10° and completely out of range.
After a good start the ignition is exactly at 10°.

Due to the very limited space in the Micra engine bay, I am unable to determine where the ignition timing is at the moment when the engine runs bad.

What I can say though...
- the error occurs sporadically
- it doesn't matter at what CLT temperature

Is it possible that this is a firmware problem?

Cheers from Germany...

You can just post an image of the basic tooth pattern, turning or cranking the engine, so we can see all the teeth and gaps on the wheel. Or a tooth log of that. If you have a cheap USB logic analyzer, they also work well for that purpose.
