Sixshooter's Brain-built MS1 Needs to Control WI
Will my Brain-built MS1 control water/meth injection as built or should I rely on some other method of control? I know there are settings for it but I don't know if the unit is built for it.

Very unlikely.
Even if it is built, the MS1 WI was designed around controlling an aquamist fast acting valve, which is now discontinued.
If you just want it on/off and not progressive your MS1 could likely facilitate this.

I would just like it to come on at 10-12psi. I know how to do that with a pressure switch but was hoping the MS would be able to handle it, since I see the feature listed in the Tunerstudio drop down menu.

Six, I used to run WI on the Silver car with a first generation MSPNP. All I was doing was simple ON-OFF using the MS software. Schematics I used are here: https://www.miataturbo.net/build-thr...e2/#post704609. I basically bread-boarded the add-on circuit and mounted it inside the MSPNP case and brought it out on spare pins.
The problem I ran into was flyback voltage from the relays would sometimes cause MS resets -- even with added flyback diodes. I eventually went to electronic relays ($). Recently, I yanked all my WI stuff when I added an intercooler. If I were to add the WI back, I'd just KISS and use a separate pressure switch I think.
