INFORMATION, I Ask for help !!! 2.4 jtdm no egr, no dpf

[Dragonfly]

Then, the car has 100k miles (who knows how many it has in reality, there is a software x check the effittivo mileage ?), the egr excluded from the map and tapped with a small plate, dpf physically removed and excluded from the map, manifold suction disassembled , cleaned .. the swirl I did not touch . Glue the original map would 210cv and 420 nm of torque.
When I brought it to sound has made a lot less horsepower ( 174cv) , hence, with the new map, and' to 215 hp and 500nm , drives very well from low up to 3k rpm where you hear a whistle coming from the turbine and/or sleeves ( don't know what it is , I have procured the silicone tubing and still have to get so change them all ) actually this whistle ( breath) you only feel when you are more than 3 thousand rpm , of facts begins to smoke greatly to the appearance of the latter
Then smoke in the accelerated from the low then stops up to 3 thousand rpm where it starts to smoke constantly up to 5 thousand.
Will certainly be the proportion of the air/fuel wrong saw the dispersion of the air
Another thing do consider : Before I'd take the dpf+kat did this whistle.. once removed it started to whistle ! I think that is the drain most****** (my idea)
--
I have read that usually the hardware for mapping costs around 4 thousand euros.. and if you take those from 200-300 euro so-called 'clone' you risk a lot to ruin the ecu..

What color of smoke, white, black, or royal blue.
If you take the clones right not to spoil anything...

Hello...so...the first thing I advise you to buy the interface mpps v12 (also here on the site) and retrieve the file that you have now in the ECU...
I if I were you, I would make the effort to disassemble icolli suction and remove the swirl (on the 2.4 ? frequently that they are eaten by the engine).
As regards the smoke, check that there are no sleeves broken, and that the mass air flow sensor is in good condition.
Go quiet that do not break anything to remove katalizzatore and prekat and dpf...these are just urban legends...removing the kat, dpf and prekat, don't do anything that facilitate the evacuation of the exhaust gases, and then recoveries also something in terms of performance. For the speech in one piece and the turbine and the other..do not break anything..but...removing the prekat, you are going to greatly lower the exhaust temperatures, and this is just FINE to the turbine.
Do as you suggest, remove the swirl, control sleeves, accurate, control mass air flow sensor, read the map, and put it...you look at it gladly
PS: go quiet that with the mpps v12 clone on the site you will not have any problem...I have lost count now of how many times I read/wrote my stylus and 147 of my brother

Quoto what mario says, but if we eat the swirl, as it happened to me to hear the noise of metal if you okay, off,
Conclusion: the new Motor!!!!

[sighline]

then the system of the discharge of this machine is : precat attached to the turbine, after the dpf+catalyst. The prect of the left , have been removed dpf+cat together ( since they are enclosed in a capsule )
But the reason for which you can donneggiare the turbine if there is the precatalizzatore ? I thought it was better if the drain is******
According to me, the whistle and give some sleeve half broken .. or the link creppato between the turbine and the precatalizzatore
Because; an engine like this could not make it ? Or that it was the turbine, or if the compressed air that comes out somewhere before you get to the cylinder , or the map to hurt after the removal of the dpf.
To be honest, the engine is hot ( after 30-40 minutes of pull at maximum in the mountains ) you can hear a ticking ( tic-tic-tic ) from the engine compartment especially in making a steep climb starting from low speed in 3rd,so arriving at 1800 (pair) the rpm sticks to tichettare .. ****llo of sound is very perceptible, very clear .. just lower the window. I don't think that it is the injectors xke work on frequencies that are very high and not feel the tic-tic..What can be according to you ? tappets ?
I look forward to that I get the hw so here reading, thanks to all

[sighline]

you do not risk anything, especially on that ecu! buy the hw and the map in the forum, I think that should be watched very carefully... if you feel a puff of air at 3000 rpm with a decrease in performance can? be the turbine enters the pump, and this ruin to in a long time!

I would like to hear some details on this your warning .. What our 'pumping' ? and as the ruin the engine? there are already some contradictions here. One says to remove dpf, kat, prekat, the other said rimontargli in case I had removed :P

[sighline]

the whistle that you hear ? due to the exhaust completely empty, you have emptied both the precatalizzatore and both the DPF and the turbine therefore behaves as a whistle.. I usually precatalizzatore leave it always in order to avoid damage of the turbo compressor, of these changes I have made so many of them and honestly the first that I did I well I made the mistake of emptying it all with a consequence break the turbine and sbiellamento engine that remained high for the oil sucked to spondato all.. the fact is that if you don't want problems, you should rimontargli the precatalizzatore and insert in place of the Dpf with a straight tube, the so-called downpipe that is the original alpha.. cos? to avoid a nuisance of shit.. as for the power of your car or rolled ? went wrong or the machine does not make since? 200cv them must have eyes closed..

I don't know what to think.. too much confusion

You're just giving advice all the wrong.
Remove the precat leads to rupture of the turbine? But when ever???
Remove the precat considerably lowers the temperature of the turbo, and, therefore, prolongs the duration.
Also on the 2.4 has a substantial increase in low rpm, as the turbo has a response pi? ready and ? pi? fast rise of pressure.
And the downpipe is not ? the straight tube to replace the fap, but ? just the semicurva to be put in the place of the precatalizzatore!
Then Sighline as I have suggested already? others read the current map that you have, just a mpps v5, and put it that we see if there are any errors.
Then check the turbo and maybe he has problems, and finally put safely to a downpipe, empty in the place of the precat, that helps you and that's it!

[Backgroop]

I tell you from experience, in fact I have a fleet of cars Alfa romeo 159 2.4 jtdm 210cv in the service will be about 120 and problems with this car come out of it are always new.. one of the many, and the breakage of the engine valves due to the malfunction of the injectors or excessive fuel injected with the consequence of breaking the engine.. I personally would advise you to leave the precatalizzatore to avoid facie leakage of the exhaust gas, which consequently result in increased rotation of the impeller of the turbocharger with a slight back pressure at the exhaust.. the valves swirl if you can delete them all..

[Alfa159 q4]

By removing the precat the back-pressure decreases and this helps.
The turbo works at temperatures ir? and low ? much more? ready.
I removed it on different 159 is 1.9 which 2.4 including my and always with excellent results.

What color of smoke, white, black, or royal blue.
If you take the clones right not to spoil anything...

The classic black smoke ( smoke, white only when the engine is cold, and especially if there is a lot of humidity, and after 5 min it stops) , I went to try it now glue the outlet of the mass air flow sensor off and think it's the same as before ( it is turned on immediately the light of the engine) .. An example : I Put the third to 1k rpm and 20-30 per hour and lunge at all .. as the revs reach 1500 begins to throw the black smoke jerky then going up to 1800 spring one of those clouds of smoke black that I miss the train of the 50's that went to the steam came out of all that crap.. ( just so so , not to believe), then at 1900 rpm stops smoking throughout , rooms at 2900 rpm starts to whistle, and again to smoke. ( the fact of the smoke after 2900 rpm and it is precisely proportionate to the whistle, occur together) Up to 5000 does not change anything as smoke; hence' . Strange noises the engine makes , and it is only after the pull to the neck x about 40 minutes begins to tichettare as I describes in my previous post
P. s with the mass air flow sensor attached smoke; hence the performances do not change .
P. s.s For mpps v15 and the ecm titanium it will take a few days before I arrive . I have already contacted one of here to buy the mpps but the sofwware I still have to try I think..
To fenire the talk I highlight this fact : The machine is 2008, 100 thousand km model 210cv ( glue turbine gtb2056v and not that of the KKK 200 hp)
Bought the car and did the cutting general glue cleaning the egr sn went to rullarla . Results : 174 hp and 400 nm ( compared to 210 and 420 of the original that should have ) . The machine smoked, but not excessively, and NOT whistling nothing.
immediately after the intervention ( dpf+cat removed , straight tube mounted ) to come from the mapper already felt clearly the whistle.
First rolled glue map 1 : 240 hp , smoke; hence' exaggerated
The second rolled map 2 : 230 hp , smoke; hence it is always that
The last rolled and map 3 : 215 hp, smoke; hence' a bit decreased, but always exaggerated ( as now)
The mapper me consgiliato to remove the egr , clean the inlet and check that there is no loss of air, and am convinced that if the machine is put in place after a non-smoker more xke is the map that I put it is 'guaranteed' .
Logically then the egr and luca stanca sn arranged in the control unit
P. s.s.s-X regarding the removal of the swirl, and' already' I and' cost 300 eu labour x plug off the egr and clean the led now if I am still with the same thing..
Anyway, before throwing money to them' I want to solve the problem with the smoke..
It is normal for the machine to go equally to both with mass air flow sensor that without?
Thanks to all !!
