The failure of Rail Bmw 320d edc17 177cv

[kingsnake]

Hi, I have a problem on a machine, I mapped a 320d 177cv, I made a map nice boost,but without touching pressile rail and limiters, and in the moment that I enter the 4 or 5th gear the car goes into recovery and in addition to the usual errors of luca stanca that do not give any trouble diagnosis I receive the error plausibilt? rail pressure.
The car is in the recovery of past 3500 rpm, I have to say that to 1600bar the injectors are open to 1000 uS, and 1800 to 950uS.
Not ? a catkin excessive as to go the high-pressure pump in gavitazione,and I ask you if you have had a similar problem and how you resolved it.

[tezzero]

based on the calculation of the ecu c'? the difference between the rail pressure ,the engine torque or other...please review the map and possibly delete all the dtc (? an ecu is very smart...)

without posting the file ? difficult to tell you where you are wrong...

[kingsnake]

You are right, but unfortunately I can not post the file.

[alfajtd]

then you have to do is rivedertela and resolve..

in the meantime, I want to do a test to the customer by connecting a pressure gauge fuel pressure near the fuel filter, to see if in full acceleration, the pressure drops, I have some doubt on the pump to the low pressure in the tank.

connects a diagnosis and see all the values that you want
usually the car if you are not done with policy, take them immediately to the error

The map I have had to do to make it go fast, to test this, turn to the 2-bar fixed, and has downloaded 237cv to 3610 rpm and 48kg of torque, the problem ? during a test on the road as you insert the 5 goes in error, and it appears plausibilit? rail pressure, unfortunately this forum does not allow me to post the file since I am a newbie.

Not, you can download up to 80 messages, but you can post

at least tell us if the map rail ? original and what you have changed, you said only the turbo 2bar
