Hello.
I`m new in chiptuning. For a month I checked and find the maps and read my chipped file from my MSA 15 ECU( VW Golf 3 1.9TDI AFN) All important maps I have found, but I can`t understand Start Of Injection map. What values are for Z axis? There are from -276 till ~1500! Theses not degrees.
In PD engine calculations for values are (z * 0,023437)-78 to convert to degrees, but what calculation is for MSA15 ECU?
Could You help me, please?

Hi,

You just need to apply the factor 0.01 and you have it in degrees. Remember, negative values are ATDC and positive values are BTDC.
