Can Speeduino handle 130 crank teeth with a cam signal? My engine uses the starter gear for the crank angle.

Actually, removing teeth from the cam is not an easy task, especially on the VVT engine I have (2001-2005). You need to fully remove the cam from the head, which is allways a task but do-able. Then you need to grind off two of the three teeth to make a single teeth cam. But those teeth are really big and on a crimped on ring:HugoW wrote: ↑Wed Jan 06, 2021 8:09 am I would like to see the Miata triggers available separately in the settings. So you can chose the regular weird 3-tooth cam pattern, and run a 36-1 on the crank for better resolution. As far as I am aware, running the Miata cam can now only be done with the stock 4-tooth crank trigger.I don't quite understand exactly what you want here?
Thanks,

Is the 36-1 an addon?
If you are going to that much effort it is simple to remove a couple of teeth from the cam to get a cam signal supported.

Basically no benefit from sequential anyway

Is this difficult pattern to add?If you dont want buy correct 60-x flywheel or there is no other flywheels you can make that work.

Speeduino only reads one edge (selectable rising or falling). While the tooth pattern is at-first confusing, the effect of what the ECM sees is what's important. Look at only rising or falling edges in the pattern. In the image below, you can see the relative and proper missing teeth equivalent (pink line spacing versus yellow line spacing), using only one set of edges:

If using a VR sensor, the edges in the image would be rising edges if the teeth moved (relatively) to the right, or falling edges if they moved to the left.

That wheel has 60-1+1 pattern and you can modify it to 60-1 or 60-2 pattern.
