Hey. Tell me what's wrong with my firmware. After the modification, the car is not gaining momentum, and it is audible as if it works on 3 cylinders ... I enclose the original firmware and the chip (chip3.bin). + Maps

As i understand, if you demand 1400 bar of rail and the svrl is not touched and is at 1350 as i think is on this file you wont get the desire 1400, also it wont cause bad running of the engine.
1- did you unplug the egr vaccum pipe to the valve?
2-have you diagnose the car after loading the moded file? is ther any DTC?

in the maps "SVRPL" I corrected 1350 for 1400.
1 - I did not detach the EGR pipe from the valve
2 - did the diagnostics, it seems that errors were not critical. I watched the data in real time, with pressure everything was fine.

please disconect the vaccum pipe that goes from solenoid to egr vaccum capsule and tap with a ball or a screw and test.

CLOSE THE RUBBER TUBE WHEN YOU UNPLUG IT FROM THE VALVE WITH A SCREW OR WHATEVER YOU HAVE AT HAND SO NO VACCUM WILL BE LOST.

Is your car fitted with the Doser valve? When disabling the EGR system this must be either isolated from the Vacuum so it remains open or disabled via the file like the other EGR valve.
