I have been racking my brain and reading everything I can to try to be able to connect my MT4S to my Super Vortex Zero. This is what I do know:

1. My SSL is enabled because the green light is solid on my ESC.
2. In System>AUX Type: I was able to change AUX1 and AUX2 to "Code Aux".

The problem is when I toggle to the mode in each Code AUX, I am not able to choose NOR or CODE10. All I get is "--------". Basically no choice to toggle. Just blinking "--------". Should I be able to change it? Can I change the settings without the CODE10 setting? Please help!!! Thanks!!!

Did you ever figure it out? I am going to attempt to set up my mt4s and svz gen 1 tonight.

The MT4S does not support CODE10 only the M12S supports this. I have both Sanwa ESC with integrated receivers ( SV-PLUS ZERO and SV-PLUS TYPE D) and I have activated SSL support on it and the only thing I see in my the sub menu for the MT4S remote is AUX1: Code AUX and then ------ For mode
you have no option the select Code10 or anything else ..
After you have done this you have to go tho Menu 8 and 9 and configure your settings accordingly .. (you should also rename the codes to your liking)
Only the new SV Gen2 supports code10 . the older generation supports normal code mode..
