Hi all. I'm going to provide as many details on this as i can to help this get a bit easier.I've read and read, but can't figure this out

So a while ago, i installed a mac valve on my miata.
12V is taken from the blue connector under the hood, and the ground is taken from the megasquirt.(PA0)
The solenoid is connected trough a switch in the car, between the ebc and the megasquirt.I can hear a click when i flip the switch so it's getting 12V.

I blew trough it in both position.With the ebc closed i can blow trough it (wastegate pressure works perfectly fine), and when open i can't. So i can rule that out also.
I've read to setup open loop first, to make closed loop a it easier. But even the open loop is not doing anything, so i assume the valve is not doing anything other then powering on and off

When i select the output test mode, i can cycle the valve and clearly hear it pumping( both on 19hz and 39hz)
In this case i assume, there is indeed something going wrong with the valve, since it works in test mode, but not when i set it up in the boost bias table.
The settings are on inverted, if i put it on normal, the switch doesn't do anything, so that's setup correctly also.
As far as i understood, the valve should cycle, even with the engine off , at a certain tps position ( correct me if i'm wrong)

At first i got the conflict 'boost in already in use, (but that was just because the pinout was active in the outputs,AND in the boost setting screen) so that is not the issue.
i used the tip in this post ( https://www.miataturbo.net/megasquirt-18/ebc-pos-46521/ ) and followed this tip below:

it's obviously operating the valve if it's grounding it out to make you go into overboost. But to check operation, turn it to open-loop mode and then set the table's lowest RPM to 100RPM. Then make it run at 50% DC. At idle you should be about to hear it rapidly clicking if you get your head near it, you'll never hear it otherwise.
you need to make sure your open/closed % are the wastegate valves not the EBC solenoid.
So it needs to be open = 0% and closed = 100% and then set it to inverted.
You should be able to put 250 into P, if not, I dunno what your deal is.
(The above was a post from Braineack in that thread )

I got the solenoid working one time by doing that.Now i have no idea why i cannot reproduce this.
No matter what number i put into the duty table, it wont cycle at idle
When i flip the switch to just wastgate pressure, it holds a steady psi.
When i flip it to activate the boost solenoid, it doesn't go into overboost in a 3d or 4th gear pull, and doesnt feel any different.
I tried to put both the duty at 0 and 100, and everything in between.
Changing pid settings doesn't help either.
Does anyone has a clue to as why it's showing this weird behaviour?

Feel free to ask any additional info , i like to get this ebc working cause i dont want have fluctuating boost when the temps change

Well guys, i got my mac valve working.. I just swapped the nipples around . The wastegate was connected to port 1 and the compressor outlet to port 3, and now they're connected to port 2 and 3 .
Now i can finally set up my closed loop boost control. Its building 10 psi at open loop right now
