EDC16C34 1.6 hdi 110hp with garret 1544v hibrit turbo.

Can somebody increase the underboost limit? or if you can remove it i will be grateful.

if i press the gas pedal to much under 2000 rpm. It flashes p0299 fault (underboost).

overboost limit should stay. But i dont need underboost limit.

Thanks.

I forgot, your MAP sensor is to 2500 mbar.
You have to change MAP sensor up to 3000 mbar.
This file not work for you.

my problem is not overboost. my problem is diffrences beetwen actual boost and request boost deviation . my actual boost is lower than requested sometimes. so that means i got underboost problem. so i need to increase the underboost limiter. maybe set it to 3 bar.. so car wont go in limb mode ne more.

Maybe you can try lowering the boost request under failing conditions if your turbo cannot handle it.

Yes, it must be reduced the boost target map or to do some adjustment on boost control map (N75).
What is a original turbo and what turbo you put in the car - turbine inducer/exducer and compressor induser/exduser.
If your turbine wheel is a original, no need to adjusment on N75map.
Very important is the turbo actuator to be properly adjustment.
