ECU Calibration

[sss222sss]

Hello,

Id like to install Versatune in my car but before that I would like to know which version I allready have in my car (for backup).

My ECU calibration is: SHYJEB000SH0B060

Is it official or ... ?

Platform: Gen3 Mazda 6 SkyActiv-D
ECU calibration: SHYJEB000SH0B060

Thanks

You have SHYJEB calibration, it is the latest official calibration for your car. VersaTuner base ROM for your car is also based on SHYJEB.

Thank fo your answer.

One more question. Now I have my boost pressure lower than desired - Manifold Absolute Pressure is 20-40kPa lower than Manifold Absolute Pressure Desired. In some conditions (high load, high RPM) its almost the same (my VT logs in attachments). Also during regeneration its the same.
I have checked intake manifold, EGR + EGR Cooler Bypass Valve (cleaned), MAP (cleaned), MAF (replaced), O2 sensor (replaced), Exhaust Gas Pressure Sensor (cleaned), turbocharger + regulation (chcecked, OK) but no change.

No error code, fuel consumption is aprox 7,8l/100km (36 mpg).

Is it normal or issue? Can I install Versatune?

IMO is it perfectly normal, during regeneration, the EGR valves are closed. Check PID BOOST_A_STATUS in ForScan (dunno if VT displays, I'm on vacation now) at full throttle. It should stick on Closed Loop during acceleration without shifting, not switch between Open/Closed or oscillate too much.

I dont understand how BOOST_A_STATUS should change depending on THROTTLE POSITION...

BOOST_A_STATUS: 0=CLOSED LOOP, 100=OPEN LOOP

Better post data than this lo-res chart...

However unusable (very few lines when filtered to load>90 and full throttle). In addition, it is necessary to log time since engine started, revolutions per minute, vehicle speed and accelerator position.

Ok, one more try...
However, the file is too large - uploaded to my Google Drive:

You're just joking, 240 records out of 12186 are APP_REL > 90. But about runtime 370 you can see constant APP 94.12 with BOOST_A_STATUS suddenly switched from Closed to Open. But from my POV, I've seen more oscillations with clogged intake/MAP sensors.
