I found and installed the CIS test gauge tonight.

Original SC WUR seem's to function normally :

Cold start (my AFR is aprox 10.1)


Warm (my AFR is aprox 12.4)



Pressure reading with the test gauge lever turned 90degree




Turbo WUR does not seem to function correctly.

The same reading is given for both cold, warm and with test gauge lever at 90degree

When connected the 930 WUR get gave a constant 14.4 AFR from cold which is reflected some what in the gauge reading.
The only thing I did notice is when the electrical connection is plugged in to the 930 WUR the pressure reading shown below
starts to bounce a few millimetres, the needle bounces that is.



Not sure if the 930 WUR is faulty in some way.
Or maybe its not getting enough pressure from the single standard SC fuel pump or something! But I would think it would at least be different readings for cold and warm!
