What engine are you torturing? Is it inside some car?

So you have 6 valves... 3 rounded and 3 not.
And they control 4 brake lines...
Abs means not esp, so... maybe not all wheels have to be controlled seperately
I mean if one of the front wheels block, maybe both of them get regulated.
I think best is figure out how they are hydraulicly wired.
A bit like a schematic. rounded ones could be some pressure release.
and the other ones for rising pressure or so.
I juuuust looked at this. Miata ABS has two separate lines for front wheels and only one line for rear wheels combined. There's also only on brake line going to the back of the car.

Things are very nice until about 2000 RPM. At 2000 RPM I start getting trigger errors :( Logs attached.

I've soldered pins to GND, CRANK and CAM pads and here is some logic analyzer data showing a miss :(

Wooohoooo!
Awesome. When I heard the whoop-wooop behind you, even I, sitting on my sofa at home, had my heart skip a beat or two. Ambulance in this case is MUCH better than our friendly Jersey City Cops.

Nice private off-road track you have here ;)

Otherwise congratulations, nice to see everything going well, especially the ETB

instant RPM does not work reliably - I am rolling back to "slow" RPM, will have to investigate instant RPM implementation

some idle PID games attached but I am a blind man in the dark here, PID tuning makes no sense to me :(

Could you post a screenshot of your settings?
Are you using Electronics throttle to control idle?
