My daily driver, Audi S6 avant -95, 2.3L inline 5, 20 valve turbocharged engine (AAN).

Installed VEMS as direct replacement of original ECU (see PlugAndPlayMotronic) using factory wiring. Extra wires are needed only for WBO2. There are some modifications with the trigger wires as well (swap secondary VR signal wires in 3pin JPT connector on firewall)

The engine is now running well, some tuning is still ahead.


Note about the time-saving effect of wiki-written documentation

It's notable that this install was carried out before other competing installs (despite that it was done in the cold, while competing installs had a warm garage host), because documentation discipline was appr 60%.

Competing installs have 10 and 40% documentation discipline so they lost, and might struggle for a few more days or weeks.

Even for this install, 3..5 days could have been saved with 90..100% documentation discipline, the firing order alone could have saved 1..2 days.

Airtemp sensor data:

Some values to make verification easier: Note that pullup is 470 Ohm not 2700 Ohm

Note that the tables are quite steep. The MAT goes from min to max from position 0x75 .. 0x92.

For the prepared tables, look for "PTC" on EasyTherm


Flying wire adaptor for basic functionality from genboard (v3.3) towards motronic connector (pins Mxx)
