<Problem>
RPM increases jerky when Flooring the gas pedal quickly.
However, If pressing the gas pedal slowly, the RPM rises smoothly.

- vehicle: NB miata swapped with k24a. The engine is from JDM odyssey absolute.
- serial number: 64860
- version: kpro4
- ECU part number:37820-PPA-A58
- KManager version: 4.5.6.0
- the calibration (as an attachment)
- a datalog of a problem (as an attachment)
- stock miata/ stock engine
- bought kpro4 at KPowerIndustries in this July

Thanks for the comments.
I just solved the problem. Looks like the fuel was too rich. I changed the map and solved.
