Hi to all guys I got a alfa 159 150 hp with a strange problem....the car has only the disabling of the egr and dpf done as has now been doing it for many years and with limiter rail turbo, and the couple moved to, and look what error does it give me? how is it ever possible?
which of the two errors you seem strange?
The problem is the the rail pressure, post the map so we can see if there is something abnormal.
be,but it's not strange...
probably if they raised the limiter is because following the error were afraid that the pressure should go up, too
instead, that error could be due to the sensor,the fuel filter is dirty,the two pumps, or any injector that is pissing and decreases the pressure...
Sorry, but it is not strange that the pressure should go up to 1770, when from the map it should do 1600?
the first error is definitely that the sensor is broken already I've had other cases...so I don't delete the dtc and are in place....
there are other maps that can give you those errors, if not post ori and mod not you can help.
Sorry, I have not understood a thing, but it only has the limiters raised or even the rest of the map?
as I wrote only the limiters...for this I do not understand....
then I had understood well,they wanted to solve the problem by raising the limiters
an update about this car.....the problem were the injectors.... redone and the problem and high pressure with the relative error removed...now all that remains is to check the geometry for the high pressure turbine, but I have a question for you: if at minimum I have the hand of the turbine, which is slightly above zero....do you think it is the sensor that has issues or you really are loading the crowd for some problem?
If you open the variable geometry and the pressure drops is the sensor fault.
But the injectors what did x get up so the pressure had no flow clogged??!!
yes, the return of the injectors was very high, and very little flow above the top....
for the crowd: ok what you say is right but as ever, moves with the machine at 850 rpm????
probably the sensor is defective
ok thank you...although I will anyway try to test the map geometry and all open to see at least how it behaves....
thanks for the advice
what will change with the map, the open geometry of?
To all open you intend to put value to 100% ?Quote:

Then to eliminate pressure spikes in certain situations it is necessary to increase the values in the map right?
no aspect I do not think that open is 100 ma to zero and then max the value can be 75.....what I do is try to understand if the geometry is locked, but you can't walk
I do not believe that the minimum that the map is uilizzata, anyway, to open the geometry, you need to lower it
x open geometry I intend to disconnect the tube of the depression of the vgt so, keeping an open turn less and see if it drops the pressure
have you checked the map if it is dirty inside?
You recovery x-pressure in the turbo?
I'm working out...it was a black piece in practice...now reassemble the manifold and all, and let's see....
you the in recovery for over-pressure turbo, and also the first rail..solved by cleaning the injectors...
then, after thorough cleaning of the intake and the turbine revision, the problems you have fixed all...except for the error p2085 on the dpf by applying the solution to the switch only, so I'm looking for the dtc with winols.....it should be the whole area of the dtc deleted from time except for the dtc of the rail pressure....
Unfortunately I can not see the maps ,but for my experience, I will say that if you have disabled the dpf you have to make sure it was removed and replaced with a fake if not the temp sensor is a bust, and recovery.... merry christmasQuote:

you I thank for the interest but I've done a lot of purging the dpf is original and I have never had any problems...always made with the switch and some of the dtc and this was the first that gave a bit of trouble....but from what I later understood was the machine that he had under problems...
But the problem of the dpf or the light revovery you me with swicht off? Are you sure you have completely disabled the dpf electronically? Sometimes it seems strange, but from software to software of the ecu are identical with the only difference of the numbers could change even if only slightly or, on the contrary the curves are you sure you have swicchato all? However, do not use I hope of software to do the dpf off because many times they do not do the job properly and can screw it up....Quote:

The cleaning of the injectors, how have you performed? On my 147 150cv it seems that is hard to climb rpm, and 3500 rpm the walls and struggling to overcome them. Having first loaded a revised map, even if done really bad, the ecu gave me the error p0091. Now turn with the map ori, but the car seems to brake to climb speed.
