It's SUPPOSED to be more accurate, yes and in all likelihood I'm sure it is but I couldn't see it being that much more accurate, if any. I got the one I liked the looks of better, plus I liked the easy of install of the MTX-L.

I'm sure they are both accurate, even to the .1 AFR. The only thing holding me back still is this whole midpipe and welding the bung to it, I'm going to check out my SLP and see if I happen to have an extra bung thats plugged off and maybe I'll get lucky...but probably not

Yeah it can be welded on the car. But i have always been told to pull the ecu and main wiring harness as a precaution incase of surges.
And yeah i dont see anyway there could be a difference in accuracy between the DB and the MTX they are the same brand

The Bosch LSU4 sensors are accurate to ±0.007 Lambda (λ), ±0.1 AFRg (with gasoline) when measuring a stoichiometric, I.e. 1.0 λ (14.68:1 AFRg) mix, however the accuracy falls off a bit in rich or lean mixes. At 0.8 λ (11.7:1 AFRg) and 1.2 λ (17.6:1 AFRg), the accuracy drops to ±0.02 λ, or ± 0.3 AFRg.
That's just the sensor, add in the controller and over that range overall accuracy will be more like ±0.035 λ, or ±0.5 AFRg--which is not too bad for a consumer grade WB system.
Keep in mind that inexpensive Lambda sensors like the LSU4, or any other $75 to $100 sensor (just the sensor), were designed to control engines, not to be laboratory grade instruments.
Here's a link to the LSU4 specs.
BTW, I have an LC-1 that I've been running for 3+ years and 60k+ miles with no problems. I have calibrated it 3 times, the last two with a method I developed that does not require it's removal from the exhaust system--if anyone wants to know more about that let me know...

Ive decided I'm definitely going with a Wideband, I have it between the Db and the MTX-L. Decisions, Decisions. I'm sure both will work great, just need to decide which style I like better I guess
