Default MTX-L GND or SG?
I'm still trying to find the perfect match between my DIYPNP, MTX-L and Tunerstudio. Currently I have the wiring for the wideband going through the DB15 connection, with 12V to pin 1, O2 signal to pin 4. The MTX-L only has one ground wire serving as both power ground and signal ground as I understand it, so would it make much difference whether the ground is wired to GND or SG on the main board?

Use GND, not SG.

Make sure you have a fuse on that 12V feed. You wouldn't want any potential problems with the wideband to disable your damage your ECU.

Is there a particular amperage fuse recommended, or is a standard 10 amp inline ok?

I'd use a 5 amp fuse.
