I feel like we could use more parameters to stabilize o2 feedback with headers, things like proportional fuel change based on o2 sensor voltage signal and possibly even heater circuit duty cycle (for maintaining proper o2 sensor temperature where headers seem to let a lot more heat escape the exhaust system vs cast factory manifolds).
I'm considering trying open loop operation to see how stable AFRs are without any o2 feedback. Would be interesting to see vs closed loop throwing its seemingly inaccurate adjustments in there.
