Just explaining things. We think there is a better method, but it requires two solenoids or a special 4-port solenoid. We are still investigating.
If someone has an external gate setup and two solenoids, we could work on testing it.
It wouldnt be hard, most of us have all 3 stock selenoids just sitting there. They are identical in function and wiring. Wouldn't think it would be hard to piggy back two of them.
I havent hooked mine up yet, still on the MBC. I wanted to see if I could get my WOT function to work first.

Ok. Well, to get started, hook up the first solenoid as shown below. We'll get that working and then measure the limitations. For example, if you have a really light spring in there, what is the max boost it can make? Once that has been determined, we'll add in the second solenoid plumbed to the top of the gate. Then we'll repeat the test and see if it can hold more boost.
I can get you the graphs and stuff in a few days...i gotta get this sucker to work on my dual boot mac (i know it will i just gotta put the driver in)...for the time being i was running it on my girlfriends laptop. Its been pouring all day so i doubt i can get it today...
I will say im only using 1 solenoid...Rage installed the controller for me with Jay on the phone giving support. They got everything figured out and it is 100% working.
I can tell you this much, the top of the wastegate is open and bottom goes to the solenoid (not sure top or bottom, i have to look) and the turbo goes to the solenoid (once again not sure top or bottom)
Do you guys wanna see the cal tables? I only have it for 13psi cause the car is not tuned, but id say it took about 4 or 5 WOT passes for it to work perfect.
It would go to 16psi or so then dump the boost to 11-14, then build boost then dump, until finally it got it right and now just solid dump and no up and down.
+1 for Rage on the install cause i sure as hell would have messed something up!

for now i havent even messed with the cal table, did nemo lower the duty cycle?
n2mb, is there a way to do this so that the learning happens BELOW my target boost? It really scares me to think when i want 24psi in 4th with my big turbo that its gonna go to 27 or so a few times to calibrate it...i mean cant it go to 21 then realize its not high enough then let some more pressure build...
i dont want to kill my motor...to me this seems fail proof and damage can only be caused by user error, but your way seems that it could overboost the motor and mess things up and if i let off it wont determine the proper boost...
long story short, if i want 24psi i dont want to see anything above it...how do we fix this?

it has an overboost feature, if it goes over your target boost then it goes to 8psi until you let off the gas
so your telling me if i want 24psi and i set the overboost to 26, its 100% going to hit 26, i can already tell...so i let off the gas and do it 5 more times it will find 24psi?? N2MB will you confirm this?

The default calibration should be on the low side so that it learns up, not down.
Set your overboost to where you want it and give it a try. If it overboosts and shuts down, then you'll need to manually go into the table and knock down the duty cycle.

It shouldn't hit the overboost limit on the first time out. It should start off much lower and learn up.
If it does hit the overboost limit, it won't learn down. You'll have to manually lower the duty cycle. I'm going to add that to the next software release, though. It is a good idea.
