How much knock? It's surprisingly difficult to knock on E47. Are u sure it's not false KR and do you know the exact E content of your fuel yet?

The most I've seen is 3.0 kr but yup it was on e47 even on e60 we got kr so we figured it had to be some mechanical. 2 of my plugs where loose, one was even leaking into the coil, I'm going to re-tighten them today to make sure everything its fine then give it another try,
Also idk if it's me but also I'm not liking the way my turbo sounds kinda sounds like screeching to me but it might be the intake that makes it sounds like that, I've check the turbo out and it's not catching on anything or scrapping.

Have you been measuring the ethanol content on your fuel?
I tried E and I had the same issue, I had knock everywhere. Ther are only 3 stations in my area and ethanol content was different on all of them.
I remember testing one and it was stupid low
Nothing wrong with the turbo I just needed to have the car done by the end of next week so I can have painted and tuned. Then make it legal and drive to my first track day this year. Turbo won't be ready though so I bought an efr so I can make it.

Measure it. I went to a station and it was 60 percent ethanol so a 50/50 mix is not e47.
Take a bit out of your tank and see what the ethanol content is.
You can do it with a baby bottle of you don't have a measuring kit.

May as well measure fuel at the station before you fill up so you can accurately calculate how much of each fuel you need to reach your desired E content. The ecm will compensate quite a bit and youwill probably be fine(as far as KR) with E content that is 10-15% lower than what it is tuned for but obviously you want to have it as close as possible for best and most consistent power.

Even with a modified fuel lobe, you will probably still have to ramp the boost quite a bit which is why I still mix fuels but I build my own trannies so.... Your wtq will suffer but whp will be OK. Fwiw I've won sooooo many races because of tq

Still waiting on turbobay to ship my R too. Gonna be an easy turbo swap with subframe and trans out of the way.
