got it all figured out and a nother ecu on the way
now to figure out the mapping
LDRXN_0A - turbo 1
LDRXN_1A - turbo 2
LAMFA- fuel
KFZW/2- timing
10000 alt decrease fuel up the turbo increase timing maybe not even touch the fuel if i increase the turbo?
Re-read up-thread. RATIO of air to fuel. Nothing to do whatsoever, whatsoever, whatsoever, with "decreasing fuel". Seriously, you are going to break something if you don't learn what the ef you are doing in the most basic sense -- and "decreasing fuel" (running lean) is one of the absolute surest ways of doing that, no exageration.
Your feeling that the car is "running rich" is due to altitude, plain and simple, unless you have mechanical issues. Audi decided that it wanted the engine to run at stoichiometric, or close to it, even at full load, for economy and emissions reasons. When you up boost above what Audi intended, you will STILL want to richen. Properly tuned, you will be showing the exact same lambda values as someone at sea level.
