boost setup
 

I apologize if this is an asshole of a question but i need help. i have a gt3076 turbo on and am trying to figure out how to run a boost controller. i have a megasquirt2pnp. my question is how to wire the mac valve. i saw ogpedxing run both wires to his maf sensor connector but do i need to run something else directly to the megasquirt or does this harness work fine for plug and play

On the side of the mspnp2 is a 26-pin connector. Pin 7 goes to the MAC solenoid and the other wire on the solenoid goes to 12VDC (the polarity doesn't matter). What happens is the MS will open and close the circuit to ground, depending on how you've set up the EBC - which, in turn, will control the vacuum signal to the wastegate. The easy part is setting up the electrics, the hard part is tuning the EBC to get a desired result.

I have a MS3PNP. I wired the mac valve to the the +12v and signal wires in the maf connector. Then inside the MS box I desoldered the maf signal pin from the board and jumped that pin to the EBC pin solder pad on the aux harness side. I could have ran a wire outside the case but this was much cleaner.

rwyatt that you for the info
jiinxy....do i have to do this on the pnp2 or will connecting directly to the maf sensor work?

I do not know - I doubt it. My MS has the 3.57 board and I wasn't able to repurpose the maf sensor input on the board to pwm output.
