So, if the data is 16bit UINT, you're only moving the data value by 1 out of 65536 (2^16). So if it shows a value of 1.00, changing it by 1 out 65536 won't do much. You might want to change it from "data" to "value" increment and put in how much you want it to jump.
It's really bad on stuff like the MAF scaling table, which is full floating point precise. You could press + a hundred times and it won't change the data by even 0.01 g/s. You need to tweak the F9 screen as above. Move the radio button down and put in a small and large increment that you want.
If the data is only 8bit, pressing + or - a few times should cause a change even if it is set default to data increment. That's only 1 out of 256 points, so pressing it a few times causes a larger change. Make sense?
Hmmm.....I think I understand what you trying to explain. The resolution from 16 bit is so high it has very little effect when changing value by just only one very small increment at a time(1 out of 65536 steps per key stroke) on the small value in the table (like max knock retard)......
In a nutshell, how could I go about and tweak the F9 screen that you explain? Just hit the F9 button??
Epifan: I found one strange thing yesterday while trying to tune my friend car. I open his rom and was able to change the values on those said tables. But I couldn't change mine when I opened my rom at the same sessin????? Why?????
My observation is I have been using my ROM image for a long time and there may be some errornous descriptions inhibited in my ROM that carried over from previous generation. Is this possible?? and most importantly, How can I correct it????
Where is the description in the EcUEdit that you need me to send to you?
Sorry that I sound like computer idiot. I know very well about tuning but less about computer programming. Sorry

I did it My Way.
