You're going to spend more money on struggling with blown turbos and shit tunes due to crappy wastegates etc. than if you just
1) bought a decent turbo
2) scrapped the car and bought a new one.
Also, what caused your current turbo to fail?

OMFG. Now when i tell there is broken turbo everyone is talking shit about china turbos. When i asked for some advice regarding tune, very few found the time to write some tips. NO it is not a chinse turbo.
I have 2 choices. Either i buy OEM garret turbo or i will try " turboworks " poland turbo which has good feedback. When it fails, shit happens, will learn and buy oem one. Why i want to try poland turbo ? Out of curiousity. I know ebay turbos are crap, nothing new.
Nyet: 1. the turbo came with car, did not know the history of it. After taking turbo off, it seems it was already rebuilt. Seems that bearing failed. There was nothing crazy on tune. I lowered boost and put OEM maf back until i got LTFT AND STFT in place. Req and actualt boost was 0.8 bar. Car drove without issue and logs seemed ok. Im gueesing turbo was worn out. As my plan was at first to learn some basics with small turbo which car came with and later to get bigger one thats why i dont see any point buying same turbo for 600eur used 900 new when i could get bigger in same price. Sorry for being rude.

Okay, so it is GT2871R only in name, and in reality it has nothing to do with Garrett, just as I thought.
You can buy a BW Airwerks turbo for like 600 EUR.
Brand new and not china shit. They work pretty well. Yes it's not the latest highend stuff with ceramic ball bearings and what not like their EFR series, but they have modern wheels, spool well and the transient response is good. And it's not chinese bullshit that's going to explode.

Hopefully by the end of the week will be new turbo installed with all the bits. Decided to go with EV14 550cc-s.
What maps should be theoretically configurated even before logging with this turbo ?

KRKTE, TVUB.
I'd set RAPP and drive DC at a flat 10%.

Anyway, got good lesson today. For those who are seeking questions regarding crossflashing softwares : Tried something new today on other car, crossflashed 4b0 ecu with 8E software and it seemed to work, then tried AK and ecu got bricked. Had to hack my FT232R cable for galleto.

So ecu is a different professor if I remember right, they changed stuff in 04ish on b6. That would have been the issue. I HAVE gotten a 032 file to flash on a 018 and it worked. Likewise I have flashed 018 onto a 032

This is driving me crazy. As i have to dial in injectors and maf, it seems impossible. I will try to dial injectors first with stock maf. Taking into consideration, that intake is custom, should i leave correction maps stock, until i get partial and idle dialed in with krkte and tvub ?

Other way around. You should know exactly what KRKTE/TVUB should be. Do that, then tweak MAF until your trims are better. If you have no way of predicting what KRKTE/TVUB should be, you chose the wrong injectors  Yes, you can do the stock MAF thing first, to get KRKTE/TVUB tuned right but you shouldn't have to. |

These are EV14 550cc 0280158117 bosch.
I calculated theoretical krkte 0,059244 , tvub from datasheet 3 bar : 2.7 , 1.54, 1.12, 073, 0523 .
For maf i used mafadjust and quick log with 2nd gear ps_W was higher than actual boost, also reg and actual afr was out of whack . Then i tried manual calculation of maf increasment and every time i got smaller results( i still dont understand how mafadjust calculates 60 to 70 with 36% increasment ) and made run. Ps_W was slightly under actual boost which per tuning wiki should be scaled correctly, but my req/actual afr went even more out of whack and afr was lean.
