EBC not engaging

[meanderthal]

Hey folks, I think I've got something set up wrong. I'm using a 3 port MAC, and the pulse test works verifying the wiring is correct. I wired the 12vdc+ to a fuse tap on the cigar lighter fuse, and the other wire going to pin R (high current 2 I think) on the MSPNP3. This is on a 2004 MAZDASPEED Miata. The issue is the boost never goes over the 7psi that I think the stock spring is set up for. it's like the EBC never gets engaged. Port 1 (rightmost) on the EBC is vented, 2 (leftmost) is plumbed to the wastegate, and 3 (middle) is boost.

Do I have it set up right? Does the msq look ok? I'm stuck.

Start with open loop boost control to figure the valve out first.

[ummduh]

I run my Mac 3 port with port 1(right) is boost, port 2 (left) goes to the top port of waste gate, port 3 (middle) is vented.

This is with an aftermarket 2 port style waste gate though

Be careful with that timing map.
