How much are you injecting? Its really fast on the video... I can only get a slight increase over stock

Well...that is question to debate.
I request max of 75mm^3, but, I think that duration is wrong so I think it is injecting more, maybe even more than 80mm^3. I'm not sure for that.

Problem is in stock duration map, it is very strange. It is up to 70mm^3 but in 65 and 70 columns are strange values; for example,
for 1350 bar CR pressure, there is duration of 871 uS. And for 1400 bar pressure for same IQ it is 897uS, and that is not logic, because with higher fuel pressure there should be lower duration.
So, I acctualy do linear extrapolation of 70 column to 75 and 80 with values 65>70...and with that much IQ I requested fuel pressure of 1450 bar...that is about 990 uS of duration...which I think is acctualy more than 80mm^3. But who knows...maybe I'm wrong.

Hi all,
I moddified my Alfa 156 2.4 JTD 10V 110KW some months ago. But I´m not confident wirh my eoi.
That is what I calculated.

negative EOI are BTDC
positive values EOI are ATDC
RPM 60mg,70mg and 80mg
750 0,206
1000 0,300
1250 0,300
1500 0,400
1750 0,600
2000 0,600
2250 0,300
2500 0,150
2750 -0,300
3000 -0,210
3250 -0,270
3500 -0,300
4000 -0,340
4500 -0,270
5000 -0,420
5100 -0,420
5200 -0,420
5300 -0,420
5400 -0,420

My SOI for these columns are of course not the same.

Hi, maybe, not Alfa, but Peugeot 206 2.0 hdi.
After remap my EOI:

Now I know, that i must add around 1degree for low-mid revs in mid-low fuel quantity for economy.
But what about high fuel quantity(55-75) for best power?
How it should loks?
(are values are in BTDC)
In this thread i see, that you have values around 0-2 deg BTDC.
It takes measureable effect when i change my EOI from 3-7 to 0-2
Thanks for help :)
