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

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
some of you I know how to say how to edit a file scania sops to delete the scr system?????
thanks
I know how to put almost all the emulators,if I remember well, the time f? I also saw the outline of how to do it if I find it posto...su the map I've never tried it, we hope that some of you have had to deal with this problem .
the problem of the emulators ? the system must be functioning and trouble-free, otherwise you can't? mount
and often the cost and effort to repair these systems ? very high
the ideal would be to exclude the system by modifying the file sops and load it with "sdp3" (diagnostic software official scania)
that clone made in china it costs an eye
? its a big problem, even why? when these systems are in failure of the engine power is reduced to 30% and on a vehicle that weighs 40ton means to stay locked
in the pi? the forces of order have a chance? check to see if the scr plant works regularly through the code information generated from the engine control unit...
not s? perhaps I ask too much :p
a better form, and we will leverage the thought and the customer will pay for the repair first, and the form then
the miracles, you can't make!!!!!
I do not think that the emulator needs the operation of all components of the scr.....
many evvero that by mounting the emulator you can? to do any less to fill the tank of adblue why, precisely, the device emulates the ecu-the operation of the system...then you could delete all of the scr including the tank,pump,injector,probes, etc..... and the ecu would not realize it in the slightest,much less the FdO,because, precisely, the little box that simulates all st? working in accordance with....
from what s? emulators alter the signal from the sensor of temperature of the catalyst so as to never reach the operating temperature required for the chemical reaction, and is not injected, the urea as it naturally happens in cold countries
during the start-up, the system performs a test of the operation of the system to check for any problems with the emulator connected
I know this system, but may be in circulation, there are others definitely
I do not think that the scr does not enter the function only because the probe of the kat does not come up to temperature....
also because of that that's? I the ecu crosses the data of this with the various sensors temp,engine temp, intake air temp, exhaust gas, etc......
and if it detects that everything and in accordance with, but only the probe kat ? the cold definitely give? a dtc.....
I would have used an emulator, and I can confirm that this works only on the temperature sensor upstream of the catalyst, and from what I understand does not ? a resistance is put in series with the sensor and feed to the ecu, and on all scania vehicles with the exception of the 730 you can? delete cos?
and the consumption of the urea ? firm
as soon as I can load the schema, and the resistance to assemble for the start-off of the scr
ok igor, I would need the schema can you post it?
hello alien to the scheme can't find it for? I can tell you how to do it:
disconnect the temperature sensor upstream of the cat, then it creates a link with a resistance of 1250hom between the positive and the negative, and then reattach the sensor after this link.
basically you'd need to add a resistor in parallel to the sensor
attention to? why? if ? the state made an update to the cent engine with the vehicle stationary, the parking brake is engaged close? partially the valve of the engine brake to increase the temperature of the cat
attention to resistance, I suggest a 2w and I can connect it in parallel and not in series
I hope this information was useful, and then let me know
thanks a lot......:rolleyes:
Sorry on the site autoobd you can find the emulator adblue including the mounting scheme, I don't know how it works if the button or not, but I know that work
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
hello guys if anyone interested I on scania 500 I eliminated with an emulator should be perfect and there are no problems
For Scania simple emulator from a few euros with 5 wires Positivo24V Positivo12/24V under the framework 2 can lines and gnd installation 5 minutes, with a fuse, if present apparatus original if you removed the emulator is active. For clarifications please contact me.
hello,I have deleted ad-blue on a scania r500 with the emulator, performance is ok, but having emptied the catalyst, turns on light engine, resulting in cutting power..***** eerrore sensor and nox, do you have solutions m & e services about this?
hello robby51039 unfortunately you have the probe nox the beginning of the muffler and went to work with the emulator, the system must work perfectly, or you find a system to eliminate it, same thing happened to me after about a year error sensor nox replaced the sensor and now everything is ok
