Bosch power problems seen in 2.1 td

[akuma406]

Well, I would like your help, because I can not tune the Bosch VE. I explain:
My 406 2.1 td pump comes with a lucas epic electronica, and made ​​the swap to Bosch VE, changing nozzles and tubes XUD9 1.9 td, 2 pumps I have seen, a source of XUD9, and another of a XUD with two mods , changed piston 9mm to 10mm, and wedges in the governor, 4mm.
Removing the electronic pump rpm box fails 3000rpm and the needle drops to 0, then I do not see many grabs the engine rpm.
I tested with both bosch see, and I have the same problem, lack power at high rpms.
With Lucas epic, in 3rd, right up to 120kmh, and short injection at 5300 rpm at 125 kmh.
With both bosch see, goes very well with 100 kmh, but the hits and misses and engine will not run, does not exceed 100kmh seems fault injection. Both the same problem.
E regulated all screws, no improvement.
I tried other injectors, lucas, and no improvement.
E relocated the lucas epic, and the engine is fine.
What happens?
Off point? The pumps are deployed to ear, and varied progress several times but no improvement, the same problem in 3rd to 100kmh, the engine fails as if there were no oil.
Insufficient supply of oil? I will change the oil filter when you can, to see if there is improvement, but has little time. . . .
Thank you very much and see if you can help me, because there are more people with this swap, and no one has this problem, and the Bosch is much better.

the english translation is kind of hard to understand, and you are swapping parts from engines that the majority of us have never seen or heard of before,  maybe pictures or something will help?

for example:

the original pump is this electronic piece of crap made by lucas because it is not upgradable

i replaced it with the older mechanical pump from a 1.9 that was modified, but it would not rev higher

then place a picture of each pump underneath each comment.  honestly my only language is english and i am not good with it on the internet since i just type as i think which does not always end up being coherent.

[TylerDurden]

No habla either, but I think you got the idea - seems the VE swap dies over 3000rpm.  Sounds something like starvation.

[TylerDurden]

Check that, maybe the tach dies above 3000 and the engine runs crappy at high speed.

maybe he needs a lift pump and better fuel filtration..

Intentare ser lo mas simple posible.
Bomba lucas epic : 3ª velocidad, 125kmh a 5300rpm, coje sin problemas
Bomba bosch ve 1: 3ª velocidad 100kmh a +- 4000rpm, a 100 kmh el motor falla y no acelera mas.
Bomba bosch ve 2, kit juntas nuevas, mod gobernador, embolo 10mm: 3ª velocidad 100kmh a +-4000rpm, el  motor falla y no acelera mas.

motor 2.1 td idi 12 valvulas 110cv, bomba lucas epic electronica (muy mala, muchas fugas gasoil, y cableado se deshace) Turbo garret t2, a 1.2bar, + chip @ +-130cv.

I try to be as simple as possible.

Al sacar la bomba lucas electronica, el cuadro indica fallo motor, y la aguja al pasar de 3000rpm cae a 0. No afecta al rendimiento motor, solo no ves mas alla de 3000rpm.

When removing the pump lucas electronics, the table indicates engine failure, and going from 3000rpm needle drops to 0. It does not affect engine performance, just do not see beyond 3000rpm.

Well, to start, you're asking Peugeot questions to a Volkswagen forum.

Most of the people here are in the U.S. and Canada, where this car was never sold, no Peugeots here for a long time. But, you might have some luck with the French forums, where there are a lot of members that are familiar with one of these, if you speak French.

VE pumps are not too different though, and my theory is that when you took the pump apart to install the governor mod, you maybe installed the throttle lever arm in a different orientation. Even changing the orientation by 1 tooth (spline) can cause a huge difference in how the engine runs. Also, you maybe went too far when you shimmed it, that is more washers than I have seen anyone use. But that could be different for these engine, I don't know.

EDIT: Also, I'm not familiar with these engines but this car but I would imagine that it uses direct injection. The other pump must also be set up for direct injection, because the fuel pressures used are higher than used with indirect injection.

El motor es idi, muy muy similar a sus 1.9 td idi, aqui hay muchisimos.
E probado la bomba 1, original, sin tocar, y la 2 con mods, el  mismo problema.
El tema de la boma, practicamente lo mismo, para bosch ve psa o W, tambien tengo alguna en casa de un 1.9 td de 80cv de golf mk3. Diferente plato de levas, pocos mas cambios.
Estoy mas acostumbrado a foros en ingles, por eso no e preguntado en el frances, pero lo hare.
Muchas gracias.
The IDI engine is very similar to its 1.9 td idi, here are many.
I tested the pump 1, original, untouched, and 2 with mods, same problem.
The theme of the boma, practically the same, to ve bosch psa or W, also I have some at home of 1.9 80HP td mk3 golf. Different cam plate, a few more changes.
I'm more used to forums in English, and asked why not in French, but I will.
Thank you very much.

you shimmed the wrong spring in the governor..

your supposed to shim the main spring (big one on the end) not the intermediate spring..

have you verified that you have enough fuel to the pump? if you are starving the pump, it will act just like you describe..

i would check your fuel filter, or just replace it to be safe..

[R.O.R-2.0]

BTW, this engine is NOTHING like a 1.9 VW diesel, of any type..

this engine is unlike anything anything we have over here in north america..

Also, you maybe went too far when you shimmed it, that is more washers than I have seen anyone use.

I have shimmed several solid,no ill effects.

He did shim the main spring.. ?

MY BAD.. my eyes werent working yet..

yes, he DID shim the correct spring..

and the difference from half shimmed, to fully shimmed, is un-noticable.. you still make the pump capable of floating the camplate..

my first few gov mods were solid. the one im running now, is only partially shimmed..

Tha's cool, its only what? 10am?! lmao
