I wholeheartedly agree as this has happened to myself while on the Dyno and will need the Primary Front wide-band 02 sensors to function and respond correctly for optimum performance especially on the Dyno! Best of luck on your Quest. Zbpd1151 said:I ordered up a new set of front, wideband, 02 sensors today.
This because the current set that's in there, from wayyyy back in 2014, had replaced the original's that came with the car when it was purchased new back in 2010.
So not wanting LMS to have any tuning issues with the SHO, once it heads out to Michigan after I install all these performance parts I've been accumulating over the past 8mo.'s, I figured I'd err on the side of safety for when my install appointment occurs in the next 2 weeks.
Besides, Chris Curtis (R.I.P.) was instrumental in scrambling to get me a set at last minute, when D. Millen was tuning my SHO (for what would be the record power and speed runs) and the original's needed replacing. Better safe than sorry.

I would say 50K would be a good rule of thumb especially while tuned. Zsm105k said:So what you guys are saying is, I should replace mine as well?

StealBlueSho said:Ha! I have a post around here somewhere explaining the exact same thing down to using the shoe string! Funny... I used a crows foot for the O2’s as opposed to cutting the wires however..
Glad it’s all done!

I can do it with my hands tied behind my back! Lol. I should created a "How To". The Front wide-band sensors can be a bit pain in the ass and found the best method is to access from the TOP of the engine and while the other 02 sensor can be accessed through the passenger side wheel well cover by removing the wheel + cover. Zsm105k said:New o2's are in the car. What a pain in the ass for the front two. It tried my patience but I got it done. Couple of things to help you if you decide to change yours.
You will need a 7/8 or 22 mm combo wrench, dikes, and 3 foot shoe string.
The front sensor is easier to get too if you loosen the 3 bolts on the turbo heat shield. I actually cut the wires on the my old ones so I could get my box end around the sensor itself. You will not be able to remove the shield completely, I just worked around it.
For the rear sensor, it is accessible by removing the passenger side tire. Use a jack stand, safety first. I cut the wires again and got my box end around the sensor and removed it. I lowered the car on the jack, and took off the engine cover. I reached into the engine bay and un-clipped the wiring harness from the stud on the engine and then un-clipped the o2 connector clips from the mount. If you look at your new o2 sensor you will see the clips for the mount. Since the wires were cut, I pulled the harness up and unplugged it.
I installed the new o2 sensor. This is where the shoe string comes to play. I made a slipknot (not the band) and fed it down through the engine compartment to where the o2 sensor connector is. I looped it around the connector and pulled it up to where it connected and tied it off so it couldn't fall back down. From there I connected the harness and 02 connector and mounted them in the correct place. I unloooped the shoe string and it was done. Two hours later mixed with some colorful language, I am pretty sure my neighbor thinks I have tourettes.
Hope this helps.

How's she running! Notable difference before and after install! Z
Yeah I noticed every time I go to 140 that cover breaks have only done it twice so haven't done it since last time replacing itsm105k said:ZSHO said:I can do it with my hands tied behind my back!Lol.

She has never run better.
I then went and ran some logs for Brad for some finalized tuning for the dyno. On my 1st-4th gear pull she was riding! At the top of 4th gear (yeah I know, save it for someone who cares) I heard an interesting sound. Sounded like something let loose and was dragging. I instantly thought side skirting...but nope. Damn skid plate/splash cover came undone. Grr....now I need to go buy some new set screws, spacers, mounts and reinstall it. So yeah. Fun.
Intercooler works damn good. I am seeing 20 to 25 degrees over ambient at the manifold. Also my car is having trouble holding more then 15 psi of boost. It keeps tampering off in the high rpms, even with the gates at 100%. So maybe the turbos are getting tired. Going to talk to my turbo guy and see if rebuilding them and adding a set of billet wheels is worth the money. Dyno runs tomorrow at 9 am.
Yeah after my 2nd oil change I noticed they had replaced all the hardware I thought it was because they found the quick connects were not staying screwed in but I think it's really because there is to much down force on that panel at higher speeds.sm105k said:^ Gjkrisa that is interesting that you said that. The seems the rear driver side came undone around that speed for me as well. I know they weren't loose. I was under the car earlier and always check them. I have noticed some play in them however. So all new hardware is on the docket for the skid plate.
Hmm. Did you notice issues holding boost Prior to the IC install! Glad it was only the cover and NO one was hurt and due stay safe my fellow ecoboosters.
