Besides, my calibration is TPS based with 0,1,2,3,8,12, etc... first indexes.

When throttle is fully closed (0% TPS shown on the sensor), the highlighted cell (at iddle) is in the 1% TPS and not in the 0% TPS column! Why ?

I carefully checked TPS parameters (voltage fully closed and fully open) as well as MAP values (0,6BAR throttle fully closed) and every thing is correct.

Please advise as soon as possible, I need to remap my calibration urgently and indexes must be set before.

Thank you.

Calibration attached :
SK2 tps08 modif RC310 7.skl
(42.7 KiB) Downloaded 23 times
I don't have any datalog available right now. Will do as soon as possible.

Yet, don't you have any idea on this issue ?

- TPS setup throttle : MAP at 0.6BAR throttle fully closed and 1BAR throttle fully opened.
- MAP sensor actually reading 0.6BAR throttle fully closed at iddle.
- TPS sensor actually reading 0% throttle fully closed at iddle.
but cell highlighted in the low fuel table is in the 1% TPS column (between 1000 and 1250 RPM) ??? What parameter can cause the ECU to select a cell in the 1% column when the TPS sensor is in fact reading 0% ???

Besides, regarding general calibration questions, do you have any feedback :
- why is the Hondata ITB basemap TPS table index range from 1 to 40% ?
- in this case, how do you adjust/tune iddle (0%) and high load (above 40%) ?

Thank you in advance.

IF you load the built in ITB calibration you will see that it does not have a 0% column. I recommend that you re index your columns to mimic this as well and see if that resolves the issue.

Hi,

I re-indexed the columns (starting from 1%) and now the cell highlighted at iddle is in the 2% column !

That is crazy! It looks like there is an offset ; do you know where it can come from ?

Thanks

Are you looking at a new datalog made after the changed calibration was uploaded?
