That's a negative again. (:

So I have the bosch 0-280-155-831 injectors (orange). 315cc @ 3bar;  334.2cc @ 3.8bar. and a B5204T5 engine

I'm calculating KRKTE as follows

1984 cc engine displacement = 0.3968 dm3 per cyl.

KRKTE = 50.2624*(1.984/5)/(operating flow rate in cc/min * .684 constant )

KRKTE = 50.2624 * 0.3968/ ( 315* .684) = .0925653


KRKTE = 50.2624 * 0.3968/ ( 334.2* .684) = .0872474

Are my calculations wrong?

I don't remember the calculation off the top of my head, but iirc it was a bit more complicated.
It looks legit, but you won't find KRKTE using this method I'm afraid.

Is CLRSHK 0xAC at 0xB1C2? Do I need to go catless change to 0xAD?

Why do you think stock value should be 0xAC? And why do you think it should be changed to 0xAD?

Because I found it in Disasm. May be wrong just begin to learn ME7. What is stock value 0x00? 0xAC is 10101100. I found bit0 set to 1 on Audi to disable. So 0xAD will be 10101101. I'm right?

Keep searching. Stock value should be 0x00.

Seems like gotcha! Few bytes 0xB1BB Grin Can I set to 0xFF to disable?
When go catless CDKAT=0 to disable after KAT check? And CLRSHK to disable physically after KAT probe so I can remove it?
What map can I adjust on 90mm dp and 76mm straight exhaust without KAT for boost control duty or it must be OK when turbo actuator adjusted in stock position? Car go in limp mode with no dynamic. Seems like torque monitoring limit or boost protection? Do I need to increase KFMIOP?
For more boost I would increase LDRXN and it will be OK with torque monitoring or KFMIOP must be ajusted also? May be some torque monitoring limit or switch to disable...
Thank you for answers!

That address is incorrect. And no, you don't set to FF to disable. CLRSHK doesn't work like you think it does.
Do some more reading. You clearly don't understand torque monitoring concept yet.

Read again and again. And read other forum topics too. It takes time to understand it all and apply. This particular thread has some incorrect info and is missing some important stuff you should know.
That address is incorrect again. CLRSHK is not even near.

It's with a heavy heart that I bring this news to you. Dream3R passed away on friday in a fatal car accident. He was a very good friend of mine. He will be sorely missed.

Rest in peace buddy! You helped me a lot and I will miss you. Although your English jokes were weird at times...
