Ok, some more research and I am already able to answer some of my own questions.

- to convert fuel map decimal info on the EPROM to actual trim (lambda) values you do: data on EPROM/128= lambda value

-to convert the timing values you do the following: (data on EPROM - 20)* 0.698= timing value in degrees

I also beilieve to have identified the WOT and IDLE maps, but still I missing some info:

- how to find the actual units for the axis on the maps (RPM, load,etc).

-Can anyone point me to where the rev limiter info is located on the '97 993 EURO Vario (OBDI)?

Thanks
