so... I already had MLV and mucked around with filtering. Ended up adding a delta channelf or each channel, then having it use the previous value if the delta was above X value (experimented to get a a balance between getting rid of spikes and retaining actual data - reached a point where it was ALL a copy of the value before it lol.
Anyway, much better:

I also did a Lambda channel calculated from AFR (I know, I should record in lambda lol!) and a TPS calculated channel from Vin1 which was TPS voltage.
Interesting, I must be getting better with Lambda scale as it had more meaning to me than the methanol AFR scale tables did. Traditionally I'd use Petrol AFR scale in the past.
