MBE4000 Boost

How much boost are you guys pushing on your mbe4000?
I get about 22-23 psi. Is that normal or do I got a leak somewhere?

 

Big POWWWWWA!!! Lol

sounds about right .

 

oh you got that right!!!

going up I26 from NC to TN about 13K LBS Im going about 27MPH. The Detroit I had in my volvo boosted up to 30PSI

 

Maximum boost of OM460 is 30 PSI. Over 30 psi it throws overboost fault code

 

So I am leaking boost somewhere?

 

MBE got closet crankcase vent system and if u have leak - u can see some oil there.

But low boost may be related with exaustm manifold leak ore stuck turbo brake ore reed valves, egr (Euro-III/EPA 2002 engines), clogged DPF....

 

I will be taking a look at the egr system, I have a feeling it's the problem.
It got worse today, I was going up the mountains with a heavy load and now only 19 psi, couple times it went up to 21psi and you feel it, then after a second back down to 19.

How can I bypass the egr completely? Can I just unplug the egr valve connector when the engine is cold?

 

to do it u have to reflash ECU, but.... DDCT cant do it. I have to take apart ECM, remove flash memory (AM20F400BB) and reprogram it on bench.

I have Mercedes Star Diagnose to work on MBE engines.

 

Oh ok thanks, another question can you upgrade torque on this engine I have 450 hp 1550 torque

 

max torque for this engine is 2200 NM

but.... there are torque correction values in its eeprom

may be changed with MiniDiag ore Star diagnose with relevant key.

The true is that correction may be from 90% to 110% in four points.
