I am considering changing the Wideband instrument that I have been using, I am not convinced by the result to do datalogs. In the Rich & ideal regime, the voltage sampling in the datalog is good, but in the most important range close to the 10/11 AFR values, the output is very fluctuating.
I was looking at two models to see if you have experience with one.
The Innovate MTX 3918 Plus & AEM X series 30-0300.- Both instruments equip the same Bosch LSU 4.9 sensor
My current Wideband Prosport equips that too, but the truth is that I am not convinced by the quality of measurement to look for something fine.
In WOT condition according to my prosport all the "rich" 10: 1 always. And I have the original tune it is impossible that it is always 10: 1. (I have already done free air calibration) I also bought a new Bosch LSU 4.9 sensor to rule out any problems, but I am almost certain that the problem is the instrument is simply not good.

Do you have a reference regarding these two brands and models? Any recommendation?
