View Full Version : wideband mounting question
07-07-2008, 11:45 AM
ok, my wideband instructions say to not mount too close to the turbo on turbo cars due to high egt's possibly damaging the sensor. what im wondering is if its ok to put the sensor in the stock o2 location on a 7mgte? or should i weld a fitting in the downpipe lower in the pipe? ive seen downpies sold for the 7m with wideband bungs right near the outlet flange of the turbo. is this ok? id hate to screw up my sensor and have to buy another one. other then this, all i need to do is make a bracket for the crank sensor and then build the engine harness for my ms2. im thinking of doing that this weekend so want to know. figure ill just reworh the harness later when i am doen with my ffi etc...

...just an FYI, the internal heater can heat a sensor up to compensate for tailpipe temps at idle, so there is no worry of being "too far" although it will give you a lagging response. ...but once you start having overheating issues, you're up shit creek.
I suggest ~6-10" minimum if you can. I tap the front of the downpipe above the steering rack. It has never overheated on me (mind you, I have one of those that actually tells me via error code when it's overheating, not just read incorrectly like others...) and cleans up the look of the engine bay.

hard part about mounting it low is the angle of the dp doesnt let me keep it tilted the proper way it says to mount it. lol. gonna have to go on the side i guess. that should be fun crawling underneath and welding the bung i bought in there. bought one wit ha plug so i can thread the plug in to block the stock port.
