Hi folks, just changed my old W2220 S class with an Eclass 2003 year 2.2 CDI 150 HP engine.
Guys, i found 2 SOI maps, one was detected automatically in Swiftec as Main SOI map, but what could be second map with more negative values from attached picture?
Problem is that i dont have MB star to log SOI and see which map is active on cold/hot on load driving conditions.

I managed to find all limiters and currently i inject 95mm3 with 1700 rail and ~1.5 bar boost, everything logged and measured with graphs.

Nop, no DPF. I tried a thing. Made second map with negative values to a ridiculous number -30 degrees ATDC.
Started engine, and shaking, well means that at least on idle and part-load acceleration(standing), that map is active.
First map, regardless values i set, no change in engine work or fuel.
