but yeah, any of those medium outputs is all you need technically. you just gotta watch out with the frequency banks, you can only setup two different frequencies between the (6) outputs.

I also thought that they all came with it done if you bought it from brain. I also didn't think I was going to swapping heads let alone building a motor...but here we are!
Can you ELI5 this to me please? Just run the wire from the vvt solenoid to like nitrous 1? It shouldn't require opening the MS should it? Just run the wire and solder it into the spot on the harness?

VVT Solenoid has two wires.
Grab power from the injector harness (white/red stripe from any injector plug) and connect to solenoid, run the other from the solenoid to megasquirt Nitrous1 to control VVT

I have an nb1. I didn't know the difference when I ordered it. I had seen everyone say that you just need to run 2 wires to the MS3X to gain functionality and I didn't think that required opening it up. Colipto's been having some issues (for some reason I think he has a reverend ecu though?) and I wanted to be sure that I wouldn't run into issues.

Step 2. Look at the plugs you unplugged, you want the DB37 pin - they have two small screws (covers) take them off to expose the wires.
It looks like this.
Step 3. Get a piece of wire, pre-tin it and stick it into the correct hole (Nit1 is pin 24) View diagram posted above.
Step 4. With wire in, solder.
Step 5, Put back together and run signal wire to VVT.
Step 6. Get power and run to VVT. ( i get mine from injector harness 12v)
Step 7. Pray to the megasquirt gods that it works and you don't get VVT1 err like me, else you'll forever be hating your non-working vvt like me.
For the record, My ECU is brain built - I've tried everything hes said but uhh Yeah let me know if yours works.

After all the messages exchanged and this post above, there's very little left to spoon feed.
I made the error of using the VVT out on megasquirt all this time. Never knew the rhyme or reason to use Nitrous1 until this thread. Oops, car still ran fine unless i'm just used to poopy idle.

On a NB1 brain uses the nitrous 1 output for the VICS solenoid. If you're using a VICS manifold you may have a bad time.

You still don't know. Not an error on a NA chassis. If built using brain's guide VVT out is unused on an NA. EDIT: For clarity, the issue with a NB using the VVT output is that brain already uses it for alternator control.

Best post ever. Thanks for clarrifyinng, that was really helpful to me. I was unaware of the site when I purchased my BrainMS3x 4 years ago, this would have saved me when later switching to sequential (as well as the questions above) instead of bombarding Brain with tons of emails as an über-noob. Sorry Brain. I guess my saving grace when swapping the VVT motor in was internal regulation in alternator, and square top.
