1.9 TDi 100hp, FIRAD 50% SOI, Dur. and ideal EOI help

Postby Ahojky48 » Mon Mar 30, 2020 3:02 am

Hello everyone.
I want to little help about SOI and Durations for FIRAD 50 with 2Bar boost from GT1752V hybrid.
I would like to ask you if, at 50% FIRAD, the SOI is more likely to be increased or decreased compared to the original file in IQ
in the last columns for reaching 220hp.
I know that if the flow rate is higher, so the SOI should decrease from the original values, but I don't know where is the ideal injecting window for that boost and hp. I tried to increase SOI even more than here (just a little bit), but I couldn't feel the power difference. Maybe I didn't know it.
So Higher SOI or decrease? What do you thing?
Right now i am riding with SOI (the top IQ) :
4700rpm = 25,3
4000rpm = 24,5
3500rpm = 20,6
3000rpm = 17,5
2750rpm = 16,3
2500rpm = 15

EOI is around 11 in the top and 13 in the middle. What do you think, that is ideal End of injection?

Here I am posting Original file.
Thanks you very much for every reacting. Mainly constructive criticism! :lol: Thaťs what i need for improvement :thumbup:
