O2 Sensors

[noone]

Okay wasnt running o2 sensor's previously and economy was so so was

around 320ish kW

power fc hks 2530's etc

running trust style (not sure they are genuine) long dump front pipes

was going to try to buy reducers today to refit the o2 sensors

only to find that the plugs I was using to block the hole on the dumps which were flush with the inside of the pipe

are nearly as long as the reach on the o2 sensors (see pic)

rough measurement I reckon I would end up with maybe 2-3 mm of sensor actually in the exhaust flow

not sure this will actually work previously the guy tuning the car said it probly wasnt worth running the o2 sensors anyway

what do you think will the sensors give acurate readings installed like that???

I modded my dumps so the o2 sensor was placed similarly to stock, so i didnt have to worry about if it would work or not.

I assume the dumps are still on the car, so maybe just try 33/34 o2s instead to make life easier.

If the guy has tuned the light load/cruise parts of the map to be 14.7 AFR then the o2 wont make much difference to economy.

Take it back to where it was tuned.

You should have good economy if the tune is sweet.

It may be pointless even replacing the 02s if they arent even turned on in the PFC.

yeah motor is out for a rebuild (should of said that)

were turned off in the powerFC

looking like I wont be refitting them

have already ceramic coated the dumps so not keen to try n mod em at this point
