Hello! Werid issue i'm having with my turbo miata.Running on speeduino. I recently upgraded to some VAG NGK COPs and from that point i keep having misifre issues. In log its an rpm spike. I have tried adjusting dwell trigger filters and a few other stuff. Even launch control on and off messes with when the misifres happen.
So far if i'm at trigger filter weak or medium rpm spikes happen when accelerating and in higher power applications. Not at cruise. When changing to trigger filter off the rpm spikes happens at deceleration, running perfectly in boost. If anybody could give me any help i would really appreciate it! Also COPs are grounded to head. Wasted COP mode. I've attached a log and my tune as well.
