When it has a high target, it can sometimes lag while duty cycle catches back up. I've tried setting the target to 1.5 degrees but it still doesn't work exactly how I want it to.

I'm trying to get VVT working on my miata, and it appears the y8s flyback diode is giving me issues. I've got VVT on Nitrous 1 output, and a 1N4005 diode between there and 12V (stripe to 12). Without that diode, I can test VVT duty cycle up to about 75%, after which the tach goes nuts and the engine revs, and I can't get the cam to retard again.
With the diode in place, I get a lot of issues with sensor readings becoming erratic when duty gets up to around 60%, and then the MS resets and goes back to the previously burned value.
