Sure. Do you have a specific question?

Looking for a base map. Engine needs to run in for 500 miles before tuning on the dyno.

if you don't want to spent money on file or do some mapping yourself, put the stock injectors in and drive easy 500 miles and bring it to dyno for tuning.
If you can do mapping yourself you have to pay someone to do a file for you...

The very basic starting point would be:
LDRAPP = 0, CWMDAPP = 0x0F
KRKTE - change it to suit 550's (you can decrease it proportionally to injector size change from stock).
TVUB - insert correct values for your injectors.

This should make the car run on waste gate pressures only and should give you those 500 miles (given: your hardware is otherwise stock, you kept the N75, you don't run crazy ass 20psi wastegate spring etc etc etc).

If it helps I started playing this ecu, the riding earlier in my b5 ref 018AQ, started working with it from a file AGU 018CG apparently if more data that ecu, and the same family, if you need to give that ecu, maps etc to go identifying not hesitate to ask, even that sure the forum already gone up, I think down here, I hope I have been helped

This spanglish is so wrong
