Hi guys, can someone help me understand how to interpret the boost maps in this type of ecu and how are the factors related to boost, im making an .ols for this ecu, but im stuck on the boost maps and its factor.
Thanks in advance.

Hi mate,
there is no turbo maps in this ECU,have maps related to "air mass inside cylinders-combustion chamber"-Units are mg air per stroke.
Maps names "Desired value for combustion -chamber charge"factor 0,2, units mg air/stroke, X axis Nm, Y axis RPM.
Look at attachment, this is 2D image of maps, from Skoda EDC17C74 .

Great!!! thanks a lot AdrianCl you just made my sunday, great help.

Isee that there is also Air maps related to Torque NM and Rail Pressure 16*15, could that be or im aplying the wrong factor? RPM factor is 0,5 as i think, in the maps im aplying does not make sense that factor so i asume there is 0,1 for RP as it will stand at 1800.

This is my original file

Anyone has more map adress on this file ?

I have some from my EDC17C74 (not sure if all matches)

@adriancl Please share your infromations!

What i found:

Nm to IQ (main??) more following 36F14A
IQ limit 3D4D92 bis 3D4D98
DW 3050B4 305158 205530
Nm limiter 3D5160 3D52CE
Smoke 3F173A
main Duration ?? 3DEA22
Airmass ?? 38E060 38E3FA


I have some more but not shure with them.

Looks like EDC17C74 and EDC17CP74 are the same map adresse.
Also different EDC17C74 from VAG seems to have same map adress.
