I've been logging and working with Specified Load, Max Specified Load, and I zeroed the MAP sensor offset and so far, great results. I'm surprised fuel trim differences are very little. Req load and actual load are real nice and no codes. Power comes in so much smoother, earlier and holds consistent at 2430 to 2530 mbar. This is a completely different car and my wife likes it too.

I will log like crazy now and take a look at timing but no issues except for a loose clamp causing a hose by the timing belt cover to blow off. I used the screw driver in the trunk to fix it Grin

One thing I can not figure out is why my car does not have KFDLULS. I am at 21.5-22.5 psi of boost from a stock 17psi and did not have this map. I suppose the ME7.5 is different regarding overboost protection.

I had to use a damos from a different ECU and locate the maps manually. I've been working on this for weeks but wanted to give some help to others with the same model car.

My ECU is 8N0 906 018 CJ and TTQS posted a damos for ECU 8N0 906 018 CB.

Here is my map cross reference and if anyone would like to verify, feel free to download my ECU file and TTQS's damos. Any items in red could not be found or have notes explaining the problem.

Some SW versions do not have KFDLULS... There is still some other maps for overboost but they may or may not play a role on your tune. Ideally you should adjust the LDR control limit so the actual boost does not go past the requested boost Smiley

Thx Gonzo, I have been doing just that. I started going up with both and tried all types of settings to get a feel for how the map changes affect drivability as well as what causes the code regarding boost not meeting requested boost.
I think everyone has an opinoin but a few that stick out for me are. Requested boost below 50% can really change normal driving so I left it alone except for smoothing out the low points in the map. And the "not meeting requested boost code" can come easily if you don't raise max boost at lower RPM ranges or another way of putting it, early in the curve.
So for testing, I went pretty steep with the requested starting a tad at 50% and steep after that. I wanted to see from 2300rpm to 3000rpm at 70% requested a full 2550mbar come in pretty linear and hold from 3k to 6.4k RPM. I then started bringing down max boost across 2300 to 6400 rpm and checking with vag com until I would see it less than 2550mbar. At that point I knew where to adjust and to mold both requested and max to make the curve I wanted and at the same time make sure they were both doing what they were supposed to do. A quarter of a tank later I feel I have two pretty good curves giving me what I want. I am soo lucky I have not gotten a ticket. Only one close call Shocked
FWIW I have definately verified out of the 200+ maps I have located in my cross reference that KFMIRL (requested load) and LDRXN (max load) are definately 100% correct for 8N0906018CJ. I never had to speed up the PID KFLDMX, any boost codes that came up with vag com were from max and requested curves out of sync. When I start tweaking fuel and timing I will give feedback on how those maps do.
