Bf Xr Engine Light

[romanooo]

Hi all, got a bf and I upgraded the exhaust, including a high flow cat. Engine light came on which I expected but was no big deal as I got a custom tune soon after. Anywho, was all sweet after the tune until a few days later when the light came back on, threw it on a diagnostic machine and the code said it was the oxygen sensors. Called my tuner and he double checked the tune file and made sure he turned the secondary sensor off. So... was wondering if anyone else has had this problem? Gonna take it back to the tuner obviously but was just wondering if there is a quick fix to this? Back when the car was stock I used to get the light come up occasionally so im thinking it could be the front oxygen sensor. Anyway as youd expect with the engine light on it runs like a tractor so any help would be appreciated!

Cheers guys

When I first got my car tuned with my current exhaust I used to constantly get o2 sensor codes come up. For a while I put up with it, but then I got my tuner to turn it off. It was driving me nuts and always made me paranoid thinking the codes were something else (prior to Xcal3). From memory it should be the o2 sensor after the cat that's turned off, not the first one. Make sure he's turned off the right one.

Who's your tuner over there in Shep town?

yeah its the second sensor that's turned which makes me think its maybe a dodgy first sensor..

umm I take it to melbs to nick the wog used to be xtc performance but think he changed the name now but yeah no one really does it in the shepp area
