Rail pressure on idle

Postby michass » Thu Sep 10, 2015 7:19 am

Hi everyone,
did anyone try to incrase Rail Pressure map in upper left quarter?
2015-09-10 07_11_12-Microsoft Excel - Tuning_calculations.png

I change 300 bar values for 360 (20%). what i get, that engine works smooth, fine.
I think, that in-20degC winter car should starts betterk, what you think about that?
where is compromise between fuel consumption and smooth work?
I know, that 360 setting consumes more battery and motor starter.
Can anyone give me some help?
360 is ok, maybe 330, or even 400?
What do you think?

Sure can increase, if idle no needed modify all, only for lower IQ.
50bar increase is fine, don't increase more because more fuel will be injected. And that's value should be fine for CR pomp exploitation

Can upgrade by 100bar from 50mg bigger IQ value. But only if tune and don't change much duration

What are the axis of the above map guys ? I know the y-axis is RPM and the Z-axis is rail pressure, but what is the x-axis ?

Some cars smells bad after DPF,CAT remove so increasing rail pressure helps a lot ;)

Hi guys I got two maps which I was studying off a 2.0HDi, which are the "Rail Pressure Map - 69890" and the "Rail Pressure Limiter - 69CB8" any idea what the axes units are ?

I'm trying to upload the .ols file, but the forum post won't let me, so I'll upload a screenshot instead
