edc15c7 332_536 EGR off by a bit

[gionag]

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.

then.... the egr I removed it, why? so much was broken, and not moving more?.. remained open. then I removed all
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 manco 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.
