Emissions remap

I've been chatting to a business contact who works for one the big auto filter suppliers. He thought 17g is on the high side for a 40k mileage. 

 

Diesel contamination of the engine oil definitely occurs, I know for example that one of the major UK engine manufacturers whom I work with uses the regen counter to drive their service interval, since this is the most significant influence on oil lube properties. Bear in mind mine is remapped so extra stress on the moving parts etc. I'm already reducing the oil change interval but without knowing the dilution effect / rate then I'm just guessing at what is the most appropriate interval.

Does anyone have an explanation for the fields 

Injections allowed 

Post injection 1 (mg/str) - is this a post or normal cycle injection, as mine is showing a positive number constantly when throttle is pressed. What units are "str"? I see between 0 and around 3.5 during normal driving. 

I'm presuming that post injection 2 and 3 are the late injection that creates the high temps during the regen, at least they do with my car. During a regen post #2 will hit between 5 and 10, #3 around 5 max.

Post injection is used during warmup too - it might be that?

Possibly. Still puzzled by the app developers units though. 

 

From other users screenshot, #1 is positive in normal conditions.
