edc15c7 332_536 EGR off by a bit

Hello !

today I made a discovery (for me...) quite strange.
on this hw and sw specific alfa 147, if you disable the EGR by-bit $71B21 the egr is effectively turned off, for?, at the same time I also inhibits the control of the antiscuotimento...
now I wanted to know...

assume that in my engine, the entire EGR system ? been physically deleted, plugging in the top and bottom.

I have reactivated the bit to get the antiscuotimento active, the machine has rightly raised the error, and given that it is the EGR...
in addition to this, what other problems I might have, if it's the avr? ? to ****s function for the injection-does it change something ?

Thanks

Why? don't try to close from the injection phase?
however, you have to leave the EGR connected to the plant.

from "step injection" this? $71EBA for non-ECMiani I gi? closed, bringing all the values to the max.
of this for? do not avoid the ecu to pull up the error.
the light on the panel does not turn on... so no hassle.

what I wanted to understand was whether to have the egr is not disabled by bit creating some other problem, or to limit any inconsistency in the management injection...

Personally on this ecu, I have never had any problems

by putting to 0 the bit $71b21 the valve anti-shaking ? remained active ? you may want to make sure which version of sw are you talking about ?

if you want to maintain the throttle valve to shut off, do not touch the bit, but also pull the line straight and put to 0 the brekpoint control, then if you don't want the error in the memory gates of the DTC in the ecu.

... I point out the area of the DTC ? no I have never worked before and I don't know I where to look for them :(

Thanks for the straight, however, clear the bp ? it is really necessary ? (and for bp, I think you mean the ones in the map egr correspond to the IQ, not to rpm..)

search the web for the sw "dtc remover v. 1.02" ? free and makes the edc15c7, bp them you can reset all and two.

I have that software, I tried it with the file ori, but nothing... is not the error EGR p0401

in attachment you can find the file ori of the edc15c7 alfaromeo hw 332 sw 536.

entrusted to the on-line service for the errors dtc, you will know how to help you!!!

Thanks, but paying to fix the problems I fall two major principles :

- knowledge
- that of sharing

why are on a forum, to learn and share...
if it becomes simply a showcase for the sale of services... then I have the wrong place ;)

anyway, I succeeded, at the end, to digest, to DTC Remover the file of the ecu, and he told me that everything was ok, the edited file. SAVED but the error p0404 (EGR) continues to come out, undaunted.
map maxata to 12740 and axes reset

you quoto in full with regard to the knowledge and sharing, tomorrow check your file if I have a moment of time, and then tell you.

Sorry if I gave you a board!!! You know Dear friend clear a Dtc nn' by all.... There are formulas to be applied and a knowledge of what you want to do!!! if the classic little nn has solved nothing, evidently, nn it is so easy, you say?
Ec the people who work on these things and throwing us into the blood and entire days to make attempts, and I can assure you that even if you buttassi blood on the maps nn would you give anything!!! Good job!!!

for the edc15c7 there is a bit to be reset, which disables the control egr if you search the forum you will find the solution

the user has already found the bit, as he said in his first message, but as you well know, that bit also inhibits the valve damper, and what he asks ? if you can inhibit only the egr without the valve.

then, extending your reasoning, what would you say here what you teach only the things that are "easy" ? if you want to imparere things more? complex you have to pay ?
I like to think, and perhaps I am the only one to think so?, that even if what you gain with the fatigue and the "BLOOD", sometimes ? also nice to share it without the need to make a profit... sometimes the knowledge is worth the most? of money. or at least I like to think so...

take it easy :D

you've got to give us a look ? I was trying to compare the two files, pre-and post-editing, but apparently the changed data do not have much sense...
