Brief glance at the binary, looks like:
0x16E3A DSLGRAD
0x16E3C DSLOFS

LMK if that doesn't fit.

R has DECOS and other stuff. Install the boost/iat sensor that the car has from factory and go from there...

Respect for that.. how did you locate this ? I have searched a lot to find it.. im sure this i correct.. values almost match the values from en ME7.0 A2L just a small difference :-)

Thx for your help :-)

Code disassembly.
Have some fully defined reference Volvo binary, so just compared this one to that.

EDIT: mentioned binary/A2L is floating around the net and is included in cracked ols for example. Search for "1xEbvsde.a2l" and matching hex file.

Hi Again

Well car runs okay now. 310Bhp 430Nm at app. 1.1 bar boost. Sadly im fighting with 2 error codes and limpmode.
981A that is Torque monitoring.
6806 that is Turbo charger system control system flow fault. Flow too low.

Anyone know how to get rid of these ?

The car needs to run on Nürnburg this weekend. 

Any help highly appreciated

Must be tuned correctly to avoid these errors. Assuming all sensors are correct for the car and car itself is mechanically good.

Everything should be ok.. K24 R turbo.. Large FMIC, 550cc nozzles. complete 3" BSR Exhaust system incl. DP with race cat. 300kpa Boost sensor

Fueling alligned with KRKTE. Boost sensor with DSLGRAD to show correct Atm pressure.

Is it allowed to attach the modded file here for people to have a look ? Im not sure if i did coorect allign KFMIOP and KFMIRL

Why did you install 300kPa boost sensor?

KRKTE is incorrect, LAMFA - why so rich at idle and low load??
IRL/IOP would need adjustments.
You've missed some important maps to actually gain considerable power.
The car definitely doesnt have 310BHP atm.
What are you using to log?

Well as im in the phase of learing the ME7 im not perfect.. KRKTE is set according to lambda adaption at idle and partload it's now arround +1%
I have tried to read about the IRL and IOP maps how to set but apparently i have missed something.
LAMFA is set low for safety durring mapping.. i will set it right when i have en other stuff right.
I have an Autel DS708 for logging.
I use WinOLS and OLS300 on the ECU.
I have tuned Diesel's for more than 10 years but i want to learn this also.
Know that there might be maps i missed but i dont have A2L for the ME 7.0.1

My Dyno is calibrated and i measure 309 engine HP and 430Nm torque.

Help is highly appreciated
