Wideband suggestions

I've had an Innovate LC-1 in my car for about 11 years now. I think it is on the fritz, not allowing me to recalibrate my sensor. The controller itself is starting to separate at the connector which I believe is the source of the failure. I'm looking into alternatives and saw that the LM-2 allows to datalog OBD2 values as well. I think this would be nice for getting a few highway pulls with RPM and AFR mapped together so I can see if I need to make any adjustments for a larger pulley and a new fuel pump. I haven't seen a lot of feedback on this device or whether you can run a gauge with it. I don't really care about the gauge so much anyway since I have not needed to adjust my tune since getting it set in 2009. AEM has OBD2 integration as well with their X-series, but I think I'd need a secondary OBD2 adapter to connect the shebang to my laptop. Leaning towards the LM-2 for my purposes unless someone can talk me out of it.

What are you running for an ECU? direct can support will be dependent on that.

Stock ECU w/PC Pro piggyback. This is just so I can see the relationship of RPM to AFR. Prior to this, I was going to use a GoPro watching my Innovate db gauge for AFR and the tach. High tech for sure, but the tuning on the cards is not very granular anyway.

That's far out of my wheelhouse, so hopefully someone else will chime in. I have the feeling there will be a few "Upgrade to a proper ECU" comments coming your way though :hustler:

Yes, I'm pretty good at starting troll threads. Things that run with belts are not as popular here, but I'd think most people here have an opinion on WBO2 systems.

The FFS/PC Pro system has its limits for sure, but it has done what I want it to do for the past 11 years, including a few track days and a little over 50k street miles. If I move on from the FFS setup, it would be to a different engine after/if I blow this one up. There really aren't any significant power/drivability gains to be had with my current setup and an aftermarket ECU, so I'll just continue to use what works for me.
