I don't *know* that the speed signal is the issue, but it seems awfully coincidental that it correlates with your power dip. Maybe it's not the...

Maybe hptuners can chyme in on if this is true.

youre using STFT in open loop currently. If it was mine, i would enable LTFT and closed loop. Then use LTFT+STFT histogram to do the fueling in...

Is the temperature data accurate? Like, you're running at 235F+?

You're a smarter man than I am lol. My mind doesn't comprehend why this little thing could be linked to that thing, however I can wrench and build...
