Was just in a debate about this ESC and did a little digging through my manuals and I was surprised to see that there are 2 different types. Apparently the Vehicles that have the Diff Brain do not have an adjustment for the bec, while the Non Diff Brain Nero IS adjustable. I own both and overlooked this until seeing a post from member RCgoogler. So I got out both manuals and found this to be true. Might be important to note.
