Ba Mkii Xr6 Turbo - Down On Power

the code for generic obd2 codes is the same for all manufacturers, but manufacturer specific codes may have different meanings for the same code number.

The Aussie Ford ECU does not know fuel pressure to give a pressure reading

Yep, sometimes it asks you what make the car is for particular codes such as a dmax fuel leak fault. I will check if it reads fuel pressure on the Fg when I get home. Never the less it does read fuel pressure when it is supported by the vehicle ECM. I'm not here to sell products but I can get them cheap if people want them.

Back to the subject at hand. I think that the CReader will give you the info needed to narrow the low power fault down. Or you could buy an Xcal for $700 off a tuner and read your sensor outputs with that.

Yep as ratter said it doesn't read fuel pressure but it does show your short and long term fuel trims.

How did you go with those checks in my earlier post?

[ratter]

fuel trims are a good tool to help asses the running of the car, that is assuming the o2 is working correctly and not getting old
