NT510 will register battery I've done that. It will adjust idle rpm. I've done that too. It will not code any convenience things like doors lock at xx speed. Carly is the go-to for that.

I was able to read live data on my transmission switch to get indications that the pins were closed when supposed to be open indicating not likely the switch but external and it was.

The 520 I think I like the form factor better but I don't know any difference in the capability. Based on availability I think they might be phasing out the 510 for the 520
