Hi,

I noticed the following effect on KManager 3.1.6 (and older ones before that). Laptop is running Windows 7 Starter (32bit).

Not sure if it's an intentional effect of some interpolation/adjustment or not, but this is what happens:

1> Start KManager (no need to attach to an ECU)
2> Choose 'New Calibration'
3> Pick any you want, doesn't matter...
4> Select 'Tables'
5> Go to low speed ignition table
6> Select 0 degrees cam angle
7> Enable 'Edit All Tables'
8> Select all cells with CTRL-A
9> Pop up 'Adjust Selected Values' with CTRL-J
10> TAB twice or select 'Set Selected values' and input '1'
11> ENTER

Now.. The map you see is all set to '1' as expected.

But when you now select any of the other cam angles in the ignition map then it's not 'flat' at '1' but some portion of the old ignition maps at those cam angles seem to remain or at least some 'non 1' values are present

Same happens with the fuel tables, but at a smaller scale (perhaps because it has a much larger variable size). Have to select a value of '500' or so for it so show up in the other cam angles.

My question is: should a specific value be applied directly to all cam angles when using 'Edit All Tables' (and is the input value somehow mis-applied to the tables here?) or does it indeed apply some interpolation based on other values/tables to modify/adapt the input value on the other cam angles?

Bye, Arno.

Thanks for the detailed instructions.

Editing ignition tables works a little differently than fuel tables. All values are made as a relative change, so when you set the values to 1, other cam angles tables will take the difference between the old value and 1, and apply that difference to the table value.

If you want to make the case that this behavior is not the best way to edit the ignition tables then I'll consider changing it.

No that's OK.. May be a good idea to explain the logic on how the 'Edit All Tables' affects modifications in the other/cascaded cam angles than the one you're editing in the help files/docs though.

Thanks for the info!

Bye, Arno.
