bosch LSU 4.9 wideband sensor vs 4.2 Is anyone running a wideband controller that uses the newer sensor?
Is your life a whole lot better now vs when you only had the 4.2?
I'm getting about a year of service life per sensor, which aint so bad money wise. But the grass is always greener and extended sensor life and more accurate at the lean and rich edges sounds like a sweet upgrade to me.

I'm still using a 4.2 with my LC-1. Having to free-air calibrate regularly is annoying at best. I drive the car enough that the sensor has to come out to do it. Now to be fair I've had the same sensor for about 6-7 years and about 12k miles. It is starting to give me errors from time to time but it's still reading inline with my NB's.
I do plan on running a dual 14point7 oem setup by the end of the winter. I can wire in two full 4.9 systems with NB simulation for less that $200 all in. I see not having to free air cal as a pretty big selling point plus a ton of the OEM's are all running the 4.9 now.

4.9 is definitely better for tuning, it gives a more stable and repeatable reading compared to the 4.2 sensor.
It's not worth it to replace a good 4.2, but if you need to buy a new sensor anyways it's a good idea to upgrade. I have a couple 4.2 sensors working good and I plan to keep them as long as they work.
For a permanent install you won't see much of a difference, keep the old sensor until it dies then upgrade if the controller supports it.

Yeah thats kinda where I was at when I posted the thread.
Since then I bought a new 4.2 sensor, installed it, and found my issue to be something else entirely.
To top it off, my particular wideband had a unique plug so the sensor had to be purchased through the wideband maker
ended up running $80 instead of $50
Wish I upgraded instead. Live and learn I guess.
