Ok, I want to make some changes on my x5 4.4i using your xdf file in tunerpro...
One of them is idle speed. I located idle vs coolant temp maps (one normal speed and one with AC ON I guess)
But I´m stuck with the f***** german names of the parameters and tables... I can´t find fuel or ignition table.
Do you know wich are them? I wish I had a megasquirt on that car like other car I own... hehehe
.
Many thanks!
I only google translated the few I needed to edit / play with
but that functionsramen gives a general overview concept of the maps english vs google translation
Be careful that XDF is EXTENSIVE it is the OLS turned into an XDF
Idle speed is gear dependent AFAIK (I edited the idle maps vs coolant speed in my 540i and it worked OK just use ultimo to checksum it)
