Before the firewall. rail EDC16C39

[tidus1985]

hello all, I have two cars that give error p0091 error rail, are two edc EDC16c39 882-772

I have to say that I made a normal map, but from the failure of the rail, even with the map the stock, I don't understand where to find the problem, we fattop the same tests with the other car always the same ecu and the problem here also with rail stock, can you give me a hand to understand if c'? some problem p limiter on the map?

I enclose a gold and 2 maps, are full to low, because of the flywheel monomassa and reinforced clutch

[sergiot]

I can't see the map attached, but this problem usually arises from a fuel filter clogged or dirty in the tank, or both.

[Alfiuccio]

with file ori have the same problem?

[tidus1985]

no, the weird problem ? a third car with map rail moddate in the same way okay, I'm starting to think that they have the pressure regulator a little sluggish or still problems at the plant nieizione, I injection 110 mm3 of diesel fuel 1720 bar and even correct a lot of the injectors, never a mistake rail

[biondo83]

Have you tried to extract a log and compare the read data?

[carmageddon]

no, the weird problem ? a third car with map rail moddate in the same way okay, I'm starting to think that they have the pressure regulator a little sluggish or still problems at the plant nieizione, I injection 110 mm3 of diesel fuel 1720 bar and even correct a lot of the injectors, never a mistake rail

why? in the first message you write that you have the problem also with stock (original), whereas above you write that the problem does not l you have?

[tidus1985]

because I badly expressed!!:D the car are 2, one leaves the error in the memory with the original rail, the other from the failure in addition to ladciare error in memory, suca carma error expression

I would like to try to pull off a log are 2 guys in my club and do not have a diagnosis and are far away, otherwise I would have already done

[biondo83]

Just to see, the condition that leads you to experience the error you have, at high rpm, after a sudden accelerated and full load?

[sergiot]

no, the weird problem ? a third car with map rail moddate in the same way okay, I'm starting to think that they have the pressure regulator a little sluggish or still problems at the plant nieizione, I injection 110 mm3 of diesel fuel 1720 bar and even correct a lot of the injectors, never a mistake rail

the values of pressure and flow in if they say little if you don't say at what speed? them ask.
flow ? so much pressure as well but if you ask to turn inadegauati you can generate the problem

[tidus1985]

Certain and obvious, the problem and that error at 3000 rpm is about to speed medium high, and then the. 4 and 5* pi? what else, at that rpm the pump can gi? to drugging perfectly 1700 bar

[legendaryslave]

I support the ears, which in the process of reviewing the fuel pump will solve the problem

[sergiot]

you may try to increase the control of the flow rate of the pump
.

[tidus1985]

What do you mean by command flow rate, the pump only has the pressure regulator to handle the pressure, I suppose, the flow is directly from the cubic capacity of the pump, I didn't know there was on the map as a flow control, since? how this would be managed?he just did not management of the variable displacement piston ?

[sergiot]

not ? a command on the cubic capacity, but a calculation done on the request of diesel.
but ? only a calculation, perhaps you are not would be useful.
but why? do not put pressure rail as the source, at least in the area of 3000 rpm ?

[tidus1985]

Both machines give you a error only via the diagnosis and the other engine failure on the display even with the radio map ori, I try to put the times ori and see if the same problem

[giary74]

have you checked the pressure regulator rail?

[sergiot]

Both machines give you a error only via the diagnosis and the other engine failure on the display even with the radio map ori, I try to put the times ori and see if the same problem

if you want to keep the car's performance begins with putting the pressure rail as the original.

[biondo83]

I recommend a nice clean cylinder (and badges attached) of the pressure regulator before other expenses for revision or pump replacement pressure regulator.

[pabloescobar]

I agree with the review of the high pressure pump and shows the rail ori

[tidus1985]

there was opensando I also to the pressure regulator, you know, he'll do it clean

[sergiot]

but what do you need to take a pressure cos? high at 3000 rpm?????? almost 20% more? of the original

[tidus1985]

if you have to inject 95/100mm3 and high blood pressure helps to shorten the injections ergo to ask for less anticpi and make smoking less the car

[sergiot]

ok , but then it means that demand for fuel delivery with that pressure ? top on the capability? hydraulic-mechanical pump hp.

[Ghizmo]

A beautiful log on the road would help me.

[tidus1985]

I agree to the log, the guys expect arrivals l elm, to the address of sergiot I would give you reason if the problem does not lay with map rail stock

[sergiot]

when you say that you have a supply of 95-100 mm3 ? a given real or have you also increased the injection map in addition to the axes???

[tranky]

Hello all, I wanted to ask tidus1985 if it has solved the problem, and how.
I find the same error, despite having slight changes on the ECU that do not exceed the 80mm3 request on the IQ above 3000rpm.
thanks

[tranky]

found the cause.. thanks anyway

[munro]

have you solved it? what was this?

[tranky]

The pump damn the other discussion...
