problem ford fiesta 1.4 tdci sid 802 poor performance

[scican25]

hi all, I have this blessed machine that's bringing me to the deep hatred towards her ..
has scarssime performance compared to other ford fiesta 1.4 tdci
I did the test with the foot pedal accelerator
I did the test with the mass air flow sensor
I emptied catalyst
but nothing the car is varamente deaf .....
I have tried different maps but it changes very little
someone told me to go in ford, and then update the ecu !
change something to update it or make a map ???

Often have problems with the injectors in these cars,have you tried to use additives in diesel fuel?if the additives enhance is definitely the problem.However, they should be controlled. THE mass air flow sensor you replaced it with a new one??

[scican25]

I don't think the problem are the injectors , also because it was changed to the engine
and with the new engine the same problem

[ingluca]

When you changed the engine did you also put the injectors of the old?
It often happened that, in following the work of replacement washers injectors (typical of this engine) because of a cleaning that is not properly careful by carbon residue from ruining the tips injector with following lack of power and no DTC stored.
For curiosity do you have the version with the MAP on the rubber hose?

I forgot ..I don't think that this car with an upgrade best ..then with a mapping takes almost twice the power... !!!

I have mapped this drive that actually do vomit to ****s performance...when I tested the car original, I looked over to poor performance is also a strange traballamento. ..after various tests I found that the injectors in these cars have problems...however with a software update that Ford has changed a lot ..then I mapped.....try to check the injectors. ...

check the injectors, and if you can do a test with a mass air flow sensor new, pèrchè also mapping it say that it should therefore not be a problem there. how many km is it??

[carlo abarth]

the traballameto and it is due very often to the flywheel ...or worse, to someone who has taken the bimassa and put the fixed ...with the soft fit resolves to the performance I am getting
of the opinion if the car has no problems with a good map you can see the difference!!!!!

the car has 80,000 km ... I can't post the map because I have a few messages
but I would like to understand that difference is an update with the map

I will test the new injectors
