9dreizig, that was my experience before when my vacuum hose from digiWUR was plugged on the wrong place. If you disconnect the hose or don't have a good vacuum where the hose is plugged, your MAP on idle would be 0.9. On idle according to Unwired Tools, your MAP on the UTCIS software should be reading 0.4 - 0.6. If it is greater than 0.6, then the digiWUR would falsely assume that you are always accelerating and making the AFR rich (as analyzed by 911st on my problem before).
I also unplugged the stock oxygen sensor and tuned my car from there (Mark Houghton explained to me the benefit of this).

You may want to read this too: pages 7-13
