Hi to all,
I find on HDS This:

PARAMETER SPECIFICATION

FUEL RAIL PRESSURE (FRP) REGULATOR CONTROL DUTY :
Fuel Rail Pressure Regulator Control Duty

(%)

It indicates the value which the Engine Control Module (ECM/PCM) orders duty to the Fuel Rail Pressure Cont. Valve.

Do you know witch is address map?

Why I cant set over 1660 bar fuel rail pressure?If I set highest than 1670 bar rail valuethe car pulls in top gear when it comes to the number of RPM... May be a limiters?

If the rail pressure is setting on 1670 bar my car rips cuts the rail pressure, the 3 rail main are all set to 1690 :?
Who is cutting my rail pressure? :?

There is other 2d limiter with rail pressure = Duty% I think.
Try hunt for 1700 in winols.
I have headr several custom tunes hitting a wall at 1670bar or there about.
1650/1660 should be fine otherwise.

No I havent found the rail pressure duty cycle %

There is 5 rail maps.

This other 2d limiters witch address map? They aren't on xdf?

Nope ;) :lol: :wave:

I figured only a complete lunaitc would want to go over 1670 bar anyway.
:thumbup:

Seriously I wasnt 100% certain and had no intention of testing them.

I'll test for you :D :lol: :twisted:

:wtf:
I'll try to find them again and update the xdf.
:lol:

I have added the 8x1 table to the xdf.
Looks like a rail pressure limiter that shuts fueling down from 1670 bar or more.
Changing the 1700 value from 800 to 0 should allow 1700 bar before the rail shuts down.

I also found these single value before the rail tables area.
F3F8A... -700 700 -500 500 17200 16700..... (= -70 70 -50 50 1720 1670 bar [oem=1600] ??????)
They may or may not be significant (16700 only occurs here and in the 8x1).
Could be related to the 1600-1670-1720 bar with 1670-1600=70 and 1720-1670=50
Indeed the 1670 may well be a single value limiter on its own.
But leave them for now and see what happens with the 8x1 table.

Pictures of logs would be appreciated ;)

THX :thumbup:
I need understand how work this map ??
0= NO limits?
1700 bar vs 800 may be cutting fuel 80 mg/str ??? :wtf:

I'm try to understand also on this map address EE8Ec and EE820
Why different value from DPF Veicle and NO DPF....
How work this maps?
