So I need to change the VVT output to nitrous 2 right? Isn't there an issue with everything using the same frequency? I.e. EBC, VVT, and IAC? Will just changing the base frequency for one of them work (and tuning again with that if necessary)?
And Aidan, will do once I can go through the above. I want to atleast try to resolve it first.

no one uses the ms3x VVT output to actually control the VVT -- unless you don't want to idle well.

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.

Nitro 1 and Nitro 2 on another.

I'm still unsure if anything needs to be modified internally...
What is even happening?
Question: If **** gets a non flappy intake manifold, can he just populate one of the nitrous outputs and be normal?
I think I got vvt working! Exhaust sounds a bit different and I can see the duty cycle move around when I drive. Sweet!
I don't have EBC setup yet, so I think the frequency issue will pop up once I turn that on since I'll have three things fighting for 511hz when I think the limit is two. I can likely change the ebc or idle valve frequency to compensate for that.
Maybe I'm making the issue up, but I thought I read that the limit was 2 things for the frequency bank.
And I'm still chasing a ******* oil leak after fixing 3 other ones.
Whack.

I would hope so... given that I can see work from my front door and walk there lol.
