Interesting range of functions:
Intake Air Temperature
Engine Coolant Temperature
Diagnostic Codes (library of 18193) (reset them with ignition on and engine off)
% Engine Load
Short Term Fuel Trim Banks 1 & 2
Long Term Fuel Trim Banks 1 & 2
Ignition Timing on #1 cylinder
Airflow Rate through MAF in g/second
Oxygen Sensor voltage and % Banks 1 & 2
but no ECU info (probably the Z3 non-compliant bit).
So basically- a whole load more things to worry about !!!
