The stock LDRXN is already very aggressive between 1000-2000rpm for the turbo capabilities.
It might be easier to test how the boost behaves on the modified LDXRN and smooth the boost spike afterwards by lowering the WGDC around 200-500rpm prior the rpm where the spiking occurs.

Solved the issue with WGDC (torque intervention).

It seems that making KFMIRL & KFMIOP to match each other is not enough.
Unless the KFMIOP axis is scaled to match the load requested by KFMIRL you will get torque intervention.

Now that the KFMIOP axis matches the highest load requested by KFMIRL the WGDC follows KFLDIMX perfectly.

I guess MED9.x is still too profitable for anyone to give out any information...

Little bump to this thread..

I was reading about MPPS being unstable over OBD on these ECU's. I have a Kess V2, will that be stable enough on these ECU's? I get really paranoid with new ECU's I'm not used to doing even with a good tool haha.

Thanks in advance..

From my experience on this ECU I was able to reflash even when I flashed a bad file.

With bad file on the ECU the car would do nothing and the radiator fans would come on.

I'm no expert though, just an enthusiast.

Could you still reflash over OBD or did you need to BDM?

I failed a flash with original MPPS, it just reconnected and started over, fans at full speed-lol.

Always do a FULL read first, make sure to save that immo data.

That's exactly what I experienced, full speed fans and strange ECU ID but I could write a known working file to the ECU with no issue.

By FULL read I assume you mean BDM?

BDM needed, immo data was corrupted.
