VVT support for mote than one trigger tooth?

Post by 960 »

I have a cam trigger wheel with 4 teeth. 2 short and two long.

Do you have any support for it?

I have all the data/angles etc. I think.

How many VVT cams do you have? Can you post some images or diagram of this wheel?

I have VVT at the intake only.

I'll see if I find a image.

It should generate something like this:

Please clarify if this that's hall or VR

The chart seems to show three signals? The one on top must be crank. What are the other two signals? Which one do we care about here?

Just think I found the reason for two long teeth.

It seems like it is for the ecu to know where "Max deviation" are.
