Hey guys, Im putting a turbo b18b civic together and i just bought an AEM wideband for tuning. I was planning on running my car open downpipe, but in AEMs instructions it says that the sensor must be at least 36 inches downstream from the turbo. I measured my downpipe and the o2 sensor bung is about 25 inches from the 5 bolt flange. I usually try to follow manufacturer instructions to the letter but this would require welding up an exhaust which i kinda dont want to do. In addition, how do guys with hood exit up pipes run widebands? That **** is maybe 12 inches at most and i would think that would definitely burn up a sensor quick. Any of you guys run wideband sensors within 2 feet of your turbo?

 

My wideband is 32in from turbo outlet, you should be just fine with what you got.

quote from the AEM document:

"A weld-in M18 X 1.5 boss is supplied for sensor installation. Mount the O2 sensor in the exhaust system at least 18 inches downstream from the exhaust port. If you anticipate high EGT's (over 800C), run a turbocharger, run at high RPM for extended periods of time or plan on running leaded race fuel then you must mount the sensor at least 36 inches or more downstream of the exhaust port as all of these can cause the sensor to overheat."

so as long as your not pushing the card extremely hard you should be fine. you can always call AEM directly

 

10-4 thanks man
