Best deal on wide band o2
- Thread starter dfarr67
- Start date
I got scammed on eBay for a Bosch LSU 4.2 for my wide band. It only lasted a month before burring out. But while looking around I noticed then that they were either over $80 or under $40. I got one straight from Innovate though in the end for $100. It's a crappy designed one as it can't handle the heat and only last three years or so.
I never had any problems with the 4.2 although all my current needs are for the 4.9 type. I'm moving away from Bosch to NTK, Denso, I'm ok with repinning a connector or finding an application where a minor modification will make them work. I looked briefly on fleabay- it's a risk. Rather use RA or Amazon- I got a open box sensor NTK for $30, it's a separate gauge anyway I can see what the ecu is doing and the truck was dyno tuned with a separate O2 shop sensor. He did find that the controller that was in the truck did not match his afr so we installed a new one which matched. I was wanting a gauge that would just see what the ecu was seeing without adding another O2, but it's cheaper for me just to add another- fresh turbo application.
Perhaps add a heat sink?
Give the Walker brand some consideration. Sometimes they are the factory sensor with a different pigtail (at a significant discount).
Already did. Home made though. You can tell when it's degrading by it's swing hi/lo. New it's only a couple tenths when in closed loop, as it ages that will go to 4 tenths and then start locking up showing 50:1 then I have to reboot it to work. The going to 50:1 is the metric I use to get a new one. Latest one has a couple of times. It's going on 3.5 years and nearly 40k miles. I think Innovate uses a different one on their latest WBO2 setup. Hyundai uses a WBO2 on the 2013s and later for the Gen Coupe as a primary.
Maybe you have the wb turning on too soon and moisture is killing it? oil contamination? I mostly use it as a tuning tool then disconnect and use nb, my latest old 4runner is using this for normal turbo operation. Honestly so far my issues have been with the inline controllers. The 4runner had a retrofit option of installing a controller on board the standalone ecu which I did. no issues so far. So far I've installed bung's in recommended locations- and only for DD no racing, I've heard about heat sinks but didn't research on conditions for when you would need them- if anything I've had O2's cool off too much on highway cruise. I read too any negative reviews on AEMs oe gauge packages and didn't know if it a function of numbers sold or they slipped in a no name brand O2- the Bosch is widely used but complaints are common= the kits are also available sans sensor. Denso and NTK are generally more expensive but there is also Delphi maybe a few others- but it needs to be compatible with the Bosch 4.9 LSU 5-pin experiments add up either way. Walker is interesting- last year of RA it was the cheapest option for a friends Chev X4 units, this year the Denso was cheaper. I don't know if your sensor is the jpeg posted but I would expect it to be cleaner than that one- too rich/oil....
