Changing fuel map scaling
Not the load scale, but the entries in the table itself. I changed mine to disply a 8bit percentage as opposed to AFR. I'd like to view it as IDC, but ecuflash doesn't allow you to reference other memory areas for the required calc.
If you want to see what it looks like as a percentage, create a new scaling and use rom to display = x/255*100 and display to rom = x*255/100
The higher the number, the richer the mix. I think it would make tuning a little easier when you know you need to add a certain percentage, especially if the trageted AFR isn't close to actual AFR.

Most old school tuners prefer to see it in raw 8bit form from 0 to 255. Your way might make it 'simulate' an IDC scaled fuel map which could help some users. I am trying to dig deeper into the fuel mapping this summer to do two things, create 100% closed loop tuning with a wideband analog input and to display the actual IPW or IDC's in each cell. There is multiple scaling that is involved which must be tracked down in the ECU coding first.
