I've got the VFD version in my MY00 car.

Do I need extra sensors to make the PSi3 read Lambda and AFR readings? I ask because mine seem to be blank. It doesn't mention in the destructions that extra sensors are required.

Theres only reference to fitting the oil pressure and oil temp sensors in the notes. Has anyone fitted other sensors - charge temp for instance? That would be handy.

Royal PITA info has dried up since they folded.

AF is messured from the ECU, but as far as I know it will only read the stock O2 signal, so not really much good tbh.

As above.... it will read the narrow band lambda sensor, which will give you an "indication". If you want an accurate reading you will need to fit a wide band lambda sensor. I am not sure if this unit will read an input of this nature though.

Thanks chaps. If the MAF was knackered would that cause no reading from the monitor?

As for the Lambda it says AF ratio or true lambda in the settings - both give a zero reading. I disconnected the Lambda recently to check to see if that was faulty (I've got a hesitation issue) and it didn't give a fault code. I disconnected the MAF which gave fault code 23 - it also didn't stall btw.
