Hello guys,

I am doing the EA839 3.0T tune by myself. (No mods, only - RON98)

First of all, my target is a strong and secure up to ~400hp crank or ~350whp.

Now pushing about 1.5-1.3bar all the rpm range with timing 9 BTDC. And in fact it is running much better than stock but still I want to make more corrections.  I know other famous tuners spiking 1.6bar and getting all the range for 1.5bar with very high 15 BTDC (Huh) at high revs.

I have an underboost after 5000rpm. WG seems to be struggling at that high rpm.

. Tried to increase 20% WGDC @ high diff pressure but results were very low.  Should I alter PID gain instead of drastically increasing DC? Maybe Derivative one?

. Should I open throttle 100% instead of 77% at lower air mass? By default it is air mass dependent but 100% is at 2500kg/h air mass. 


Very sadly every time I had to bench ECU to flash files, because my tool can't unlock the processor for OBD flashing. So better I take community help to discuss. Maybe there are EA839 3.0T tuners in here. Smiley

Vehical probably real time tunes these.

It does... it also makes useful logs, unlike what we have here.
Btw OP, when making a log put it in manual and make a single pull in a single gear through the whole RPM range. Not what you are doing here.

I quit tuning before these became a thing, so I can't really weigh in on calibration questions.

Yeah I had logged 3th gear separately, but also wanted to see boost during shift. 
VehiCAL also offers https://tools.vehical.net/VAGMG1boostTo make WGDC tuning very simple like the old ECU.
Just a question - for real time tuning what interface I need quite I do not understand. Is J2534 Openport enough? 

Also details:
