Hi, I have written a Master 2.5 dci 120 MY2007 with kessv2 clone to make stage 1
Supported Injectors and everything OK.
When the engine starts, after one second the engine stops. I say wait is strange

DF053 Rail Pressure Regulation Function.
1.DEF. upper limit exceeded.

Freeze data:
Engine: 611r.p.m.
Rail Sensor: 1782,70bar (max. sensor value)
Demand ecu rail pressure: 311bar

Original file is written by EOBD again. Same error.
When im doing the diagnostic is one error is writing

Rail pressure regulation function
Above the max level

So, i dont touch nothing just obd for read and write

If i will try with another rail pressure sensor. I am sure will be the Same error, same values. Because im not the first with this error at this Forum
Now what can I try please ?
Does anyone know a similar problem?

Regards
