Title: EA839 3.0T Tune Post by: RocketGO on March 16, 2023, 02:35:05 AM 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 (???) 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. :) https://t.ly/qBJt datazap Title: Re: EA839 3.0T Tune Post by: jcsbanks on March 16, 2023, 04:04:32 AM Hello guys, I am doing the EA839 3.0T tune by myself.

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.

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: 06M907309D EV_ECM30TFS0118W0907559H 001009 8W0907559H 0008 V6 3.0l TFSI J623 4 L |
