You’ll run into that jittery drift every time you throw a fresh O2 into the mix. Those new chips are picky about bias offsets and temperature coefficients. I always start with a clean baseline—zero the sensor at a known rich point, then let it settle before pulling the data into the fusion loop. If the curves keep sliding, check the voltage reference and the ECU’s internal filtering. The sensor’s output can shift a few millivolts for each degree Celsius, so make sure you’re compensating for heat soak. Also, don’t forget to lock the sample window; a sliding average can smooth out the peaks but also make the curve look like it’s moving. Once you nail the offset and temperature compensation, the fusion should hold steady. If you still see wild swings, the sensor might be hitting its hysteresis limit – swap it out or add a small lag to the algorithm. Remember, patience is key; a half‑swinging curve is easier to pin down than a runaway one.

Good plan. Keep an eye on the offset drift – it’s the silent killer. Once you’ve got the curves flat, you’ll be ready to tackle the next tuning puzzle. Happy hunting, and let me know if the lag buys you the win.

Sounds like you’ve got the right toolkit. Keep tweaking, and when it finally steadies, let’s celebrate with a high‑octane toast. Ping me if it keeps dancing.

Nice. Keep me posted, and when those curves finally sit still we’ll crank the engine up and toast to it.

Sounds like a plan – just keep me posted and we’ll fire up the machine once it’s steady.
