elimination adblue on scania vehicles

[igor]

hi all could someone tell me if ? can delete the adblue on scania vehicles by remapping the engine control unit?
thanks to all in advance

load the map the gold of a scania R500 euro 5 with "scr" (selective catalytic reduction)
the map ? ori and hw motorola

if the medium in question is mounted on a scania ecu DCP4 I believe that you cannot delete from the sw of the adblue as a mountain-an electronic form of management for the urea exclusively dedicated to the system of selective reduction to the outside of the ecu itself, but which interacts with this in canbus......
? a p? a hut to delete all......
the only way for the moment, I believe, is to assemble an emulator on the adblue module that interfaced with the latter and with the ecu "deception" this last.....
if, then, the means of mounting an ecu bosch edc7 I believe that something can be done via sw.....
but you should contact users more experienced than me in the field.....

no to the catalyst, there are no problems, on the contrary
often clog up for a bad operation of the scr plant and forming real and caps urea crystallized to the point of completely occlude the catalyst

eye that many times, for who knows? what a strange reaction in the catalyst, the form of sulphuric acid!!!corrosivissmo!!!I played three suits lately with that stuff....

[munro]

ah...also I wanted to ask with the catalyst and then what will you do???
I think that if you leave him, cos? com? has a short life......

[igor]

currently I know that use of additional electronic devices that fool the sensor of temperature of the catalyst, but as all the modules ? a deception but not a solution
I was looking for a system to exclude the control of nox and delete the communication between the two units without turning on any light or error can communication and to stop the power supply to the control unit scr
the control unit of the engine ? a motorola s6

I did a test by removing the probes from the muffler ,by closing the holes with the caps , including nox ;the ecu so it sees the muffler always cold and no longer sees the emissions so there is no need to inject adiblue to try, however, on the scania

[munro]

expect some big tell us what you can? perhaps something using the map you can do....
who knows if ******* unable to delete the scr???

[igor]

that scania is not ? a true catalyst, much ? that does not have pressure sensors pre and post catalyst, and on many vehicles are equipped with even a diverter valve mounted before the catalyst that eliminates the muffler to create a direct discharge and increase the noise in the exhaust, and not to create fault codes ? enough to pass a small amount? gas necessary to gently heat the catalyst
