i have bin file with moved rev limiter up 7000rpm but all maps are scaled to 6400 rpm how to change this value?
In the constants/scalars window the rev limiter is set to 19260 what that about?
next question where will i find iddle rpm ?now it is 650rpm but i will like them to be 900rpm how to change them?
thanks for help

most tuners never expand map axis despite raising rev limit. This is because amount of time spending in 6000 to 7000 rev range is so minimal.
You got to use proper bin file with xdf for maps to show correctly.

it is already posted. As for now it will not be able to adjust idle speed. Thats because I don't know where they are at, but I can guess it if you want to experiment.
Idle speed location in the bin file that is available for download here at tunerpro.
Hex address 7988, map size 1x4,
7992 maps size 1x4
79A6 maps size 1x4
One of those should be it, so try it. you can add those to the existing XDF if you know how to edit it, it is easy,
