It's for passats but the main concepts are the same.

I know why,

My low pressure fuel pump inside of fuel tank can not deliver as much fuel as I would like to at those low revs
(pressure in the fuel system before the Bosch pump is not stable enough).

This could be compensated a little with rail pressure precontrol value map,
but ECU does it own calculation based on max rail pressure achieved and if you tune the map too much,
ECU will take just as it needs, nothing more (unless you burn out your rail sensor before that).
That's tricky map to tune (will talk about it later in another topic).

My largest injection quantity is till 3000rpm and than drops.

Height pressure Bosch pump in that car can not suck fuel by itself.
Fuel has to be delivered by fuel pump from the fuel tank - we were talking about.

I am looking for new Bosch fuel pump inside the fuel tank.

Stock fuel pump operates at 250kpa and it is able to deliver 150L/h of fuel.
My car needs more. Calculation says that 180 L/h will be enough. I will probably stay at 250kpa (thinking about 300kpa & 180L/h).

This could be useful for others that would like to tune their cars:

Original - Fuel pump Peugeot 406 2.2 HDI ENGINE: 4HX, POWER 98kw
0 986 580 216

Operating pressure 250kpa
Flow Rate 150 L/h
##################################################################

For tuned car = 250kpa or 300kpa
Flow = 190 L/h (at least 180L/h)

Suitable pump for tuned car:

0 580 464 098 (HYUNDAI: Santa Fe) - 250kpa, 184 L/h

I am attaching the Bosch catalogue.

Ecuedit, the Peugeot pump is a pump in the fuel tank, but the Hyundai pump is a inline pump. so how do you use it?

He's fitting the sole pump inside the Bosch lift pump assemply, removing the original pump. I'm donaing him a working bosch lift pump and assembly to test on.

OK, I understand, just replace the pump part.

You said Ecuedit made me save a good hundred euros on my injectors, which now are like brand new. What did he do? because my injectors aren't 100% too.

He has a friend in the trade, he asked 150€s for fixing all my injectors, replacing the worn parts and re-calibrating them. That's a lot less than the standard quote of ~80€ for each injector.

after changing map, unplug and block the tiny tube that goes to the valve, block the EGR tube that goes to the inlet manifold.

Hi, please, can you tell me before the mechanical part, what is the best method for remove the egr?
Winols editing the sequence: 001 001 000 000 001 000 001 000 001 048
Or EcuSafe?
Or both?
If the sequence, they should be 000 001 000 000 001 000 001 000 001 048
or 000 000 000 000 001 000 001 000 001 048 ?
Thanks in advance.

Yes, should be 000 001 000 000 001 000 001 000 001 048.
If do like 000 000 000 000 001 000 001 000 001 048 you off turbo solwe control.

Hello.I am driving with IQ93 Map custom made for me by EDITECU ? Remap is perfect car flyes.Very satisfied :) What about this fuel pump in the fuel tank.Do i have to change it for better power below 2k rpm ? With this from Santa fe ? If it will be better i wil change it :)
