Can't see anything immediately wrong on the calibration but one of the Hondata guys maybe able to comment further.
Sounds like a sensor, wiring or ECU fault to me.

What O2 sensor are you using?
Have you had opportunity to test the sensor in another car to confirm it's not faulty?
I would also check the wiring to the sensor is correct.
Could you share the calibration file too please?

Ok, thanks Hondata. I'll investigate replacing the sensor with a more sensitive one.
Many thanks for your help.

Hi, thanks for your reply and analysis.
I was probably descending a hill at that point as I was certainly off the throttle from the drivers perspective, perhaps not from the TPS perspective though. Is there a way to see the raw TPS voltage from KManager?

I'll investigate the battery voltage ...

Hi,

I am experiencing a problem with inconsistent overrun fueling which I'm hoping someone can help me to understand.
Sometime fuel is cut during closed throttle decel but sometimes the engine continues to add some fuel. This results in slight rev hang if you dip the clutch, inconsistent ...

Thanks Hondata.

I'm running KManager 4.2.6.0
I think there maybe a bug which is causing the "Idle Ignition Control - Range: Max Advance" setting to not get saved as part of the .kal file.
If I set anything other than the default of 5, then save the file, restart KManager and re-open the saved file, then it changes ...
