opinions upon which WB02 i should buy to properly log with V2 VIA serial com

[djv86]

so i currently use the AEM eugo b02 sensor and works great.. although it doesnt have a narrowband output as in which i need to properly tune vehicles without adding 02 bung in every customers vehicles.

I'm looking between the

plx sm-afr

mtx-l

they both use narrowband outputs although the plx needs some mods for serial data logging which i will be using also

If you are tuning in open loop why worry about simulated narrow band?

Going be using the calcvet method which uses closed loop I believe except in pe. And I don't wanna have to add an extra bung in each customers vehicles to tune their vehicle.
