Faulty diagram for Idle/Deceleration Timing vs RPM?

[tim_tub]

Hi

Is there a bug in the Idle/Deceleration Timing vs RPM diagram?
The diagram sais for example 15 at 0 rpm when there should be 31 according to the information in that cell and if I change the cell to 15 or lower it "goes crazy".

I'm running 1.2.11

The Nissan ECU uses an offset for some of the timing tables

So raw value - offset = graph value

Right click to use filtered values

Dont change it to '16' raw value, but use the original value and the graph as a guide

Thanks Matt!
I was just playing whit the settings offline (haven't used NisTune for a while!) so I wasn't planning on doing anything particular but I thought this was a bitt odd when I saw it!

But I don't understand why I get 127 filtered when I enter 15 raw.
(Warning, stupid question) Shouldn't it be 0 or perhaps minus "something"?

I think the value wrapped around there
