View Full Version : MSA15 SOI map

16th June, 2018, 08:46 PM
I want to tune my VW Golf 3 1.9TDI AFN. I have chipped already, but I want to do some changes. All important maps I understand, but I have problems with SOI map(z axis). What are theses values? There need to be degrees, but there are bigger values. I know, that PD engines factor for Winols for SOI map is z * 0,023437-78, but for MSA 15 seems to be another factors. Could You help me to understand SOI map, please?

SOI factor is 0.01
It might be a real factor. Somewhere in forum I read that the factor is 0,023437 without -78.
Which could be a real factor for SOI map? Maybe need to do some logs from vcds and compare the values with both factors..
But the real factor sounds like will be 0,01, because, if there is 0,023437, the max advance is 40 degrees. Its too much..

0.023437 is for edc15 and edc16 no for MSA
just open a damos file for this old ecu and you will know everything
