Hyundai genesis coupe tuning

Hi,

Anybody was able to tune genesis coupe either using VFTuner or any other solution?

I've been reading the Continental Theta 2 documentation for a while and I'm having a hard time setting up something.

I think it's using a custom version of SimOS (looks similar to SimOS 8.5 from what I found)

Anybody could point me to some kind of documentation that would help?

I have potential customers waiting for me releasing tunes.

I found ignition timing tables (even, though negative timing for crackle seems to create issues (don't judge me on that, I let know the customer the downside but it's still something really appreciated from this crowd))

That's about the only thing I found, even the DTC aren't clear

Thanks

It may help you get a response if you could post the vehicle's year, engine it's using, maybe the transmission, and certainly if you can find and identify the ECU used?
