Hi,

I am new and need help with BMW 404 xdf . I downloaded this
xdf in tunerpro definitions section.

I wonder what are map values "units" or equations of this xdf(x,y,z). There are maps what intrest me.

-ignition maps
-maf map
-fuel maps

Also how I can change values of ignition map in degrees.

Thanks

I wrote that XDF, it is pritty raw, if you don't understand what it all means, you should not be tuning your car at all.

bemyy,

the conversion for ignition is ( x * 0.75 ) -22.5
that will five you real BTDC ignition degrees

Hi, now I have tested that equation and it is not correct in
idle spark map. When I check with ignition lamp.
We made other eguation X*0,17636-11,46 what work with idle spark map, but these is some issues. when I use this
equation it works only one way? How I made this work both ways?

is that equation( x * 0.75 ) -22.5 for part and WOT spark trottle?
And also need help about spark part trottle map. I use xdf what is
tuner pro download section. Is that address correct CA9E, I think
that is not!
