R32 Gtr And Pfc

[warriorbrawl]

Hey People,

I have read up on the various o2 threads.

I am trying to find out what readings your Power fc gives for the 02 sensor at idle and cruise conditions is it the same as the R33 gts 0-1V?

This can be found in the etc mode under sw check

Thanks

also for a gtr with mild mods

full exhaust

cam gears

PFC

what sort of L/100kms are you getting

Highway and city

I get 300city and 350 Highway on a full tank (taking it easy)

Thanks alot

It should oscillate between about 0.1-0.9 volts holding it at 2000 rpm and in a steady state cruise situation. Should be the same for amost any votage based 0-1 volt O2 sensor. Thing to check is the bias to chassis ground and also ecu ground.

It should also be checked with a wide band o2 sensor to show that the 02 sensor is not slow to react. Often harder to tell then just a faulty sensor.

Thanks for the help, the bias to chasis ground where is the best place to check this?

Also I think the R32GTR and R33 GTR have different 02 sensors R32 is the smaller style nut R33 is Large style but the Power fc is for both r32 and r33

Does the 32 o2 sensor even work with power FC?

This is the same as S13 early models (red top) have small style late models have large style nut eg (black top)

Bad injector atomization can cause sluggish o2 sensor operation.

So if you replace the o2 sensor and still have issues at low rpm look at the injectors.

[rob82]

They both use a 0-1volt range as far as I'm aware so it should have an issue PFC. Chassis ground - as in anyware you can get a good contact to ground ie in a bolt hole. All your doing is checking that there is no voltage between grounds for the o2 sensors and chassis or ecu.

[rob82]

Should not have an issue!! Sorry.

[warriorbrawl]

Ok so basically you would be checking for any voltage feedback into the o2 sensor.

to make sure its not giving a false reading to the ecu-right?

thanks

[rob82]

Exactly.

[warriorbrawl]

Ok I checked that out so what is the o2 reg in the functions screen do

I have the o2 F/B turned on. but there is a setting under it?

[rob82]

I'm not sure what the 02 reg does maybe it selects the type of 02 sensor ie narrow and wide band havn't really delved that far into ever. The 02 feedback should be the only setting you need to enable closed loop fueling.

[warriorbrawl]

Yeah I just wonder if it is a feature to enable you to use either r32 or r33 o2 sensors (if they are different as I suspect) it is in my manual but in Japanese:(

Cheers

[warriorbrawl]

I suppose I could try it for a tank and see if it is any better. Carn't be much worse

by the way both my sensors have been replaced-Cheers
