Yeah, it wasn't something I was expecting. I showed Gesso and he immediately 'd as well. It contacts the nut on the center shaft rather than the blades, but yeah, still no esta buen.

<br />Would someone like to share said skunk 2 TB settings?

Now that I've got a little blood in my coffee system, I'm realizing that unless we can somehow get the boost under control at low(er) RPM, boost by gear isn't going to accomplish much. I'm looking at YOU, internal wastegate.
As has been mentioned in this thread previously, I'm seriously curious as to what TSE has cooked up to keep these things in check.
Also, this will be relevant to our interests:

With port A blocked it should work just like a 3 port MAC.

Like voltagers and hz and all that mumbo jumbo?
also do you want me to just plug this into the EFR plug temporarily or hack that off and wire it in properly? I can kinda sorta solder, lulz
#2107
yes, same frequencies. Remember though that the frequency for a boost noid isnt a set number. You gain faster boost control response (ie the actual control loop works faster, not spool) with higher frequencies but it makes the effective range of duty cycles smaller (like you need higher dc to have it be noticeably on and its effectively saturated at lower duty cycles). And the opposite of all that.

Alright, so I test the MAC valve today, it works.
I hook it up, and the "fun" begins. By fun I mean, this stupid MS is doing something weird and I don't understand what.
As long as the valve has power to it, the car makes 16-18psi and hauls the mail.
NO MATTER WHAT YOU DO in Tunerstudio, it completely ignores everything and runs the above boost. I have tried 19.5hz, I have tried 26hz, I have tried "normal" settings, I have tried "inverted", I have tried open loop and I have tried closed loop. The car either makes "ALLTHEBOOST" (well, at least much of it), or NONETHEBOOST.
What do?
Here's the boost control settings:
Sending Rev a PM, but speak up if you know what's wrong?
Per Reverant's instructions, Boost is wired to Pin: 20. I have double checked this on the DB37 and it is indeed so.

Boost duty in TS does exactly what it's told. In open loop I 100 out the table it reads 100, if 50 reads 50, if zero reads zero. In closed loop it jumps around "attempting" to hit the target.
But it's almost like something inside the MS is grounding the stupid circuit permanently so that it runs ALLOFIT?

Maybe, but here's the issue:
When I turn on the ignition (car not on) the solenoid clicks.
I touch ground to car and it clicks, and I touch ground to wire going to MS and it clicks.
Meaning as soon as car has power, it complete's the circuit. Shouldn't it only "close" the circuit when it's actually attempting to operate the EBC?

I tried both, and neither worked. Thanks for that screenshot.
Do you have 12v going TO the valve from a power source, and Ground wire FROM valve going to pin/wire on MS (for EBC, or switched ground)?
I just want to make 100% G has it wired correctly before I keep testing different things.

Alright, so this appears to be 100% an issue with the megasquirt.
I have confirmed that:
1) EBC/valve works 100%. The ports on the EBC being used are 100% correct as well, and 100% correctly connected to the turbo.
2) there is switched 12v power going to the EBC
3) the EBC is grounded to pin 20 on the DB37
4) per Rev's instructions, pin 20 is EBC, and in Tunerstudio is labeled as "Boost"
5) the boost control settings are correct, and set to work off "Boost"
6) I've tested pin 20, EBC input pin, and it's PERMANENTLY GROUNDED. This is incorrect.
Sent Rev a PM, I really hope to finish tuning this car, it's done aside from the EBC fiasco.
