Want to use ECMlink to control boost? Well here's how you do it using the stock boost control solenoid. I am using the 1G solenoid, which looks a bit different than the 2G solenoid. The principal is the same for both solenoids, just make sure you route your vacuum lines correctly, and put them on the correct nipples.
Start by removing the stock restrictor pill from the solenoid nipple. Here is the 1G solenoid with the restrictor still installed:
And here is a picture of the restrictor removed. Find a tiny screw, and insert it into the restrictor. Then, use a pair of pliers or something to pull it out. It should come out easily. If it doesn't, your screw is probably too big.
Now that the stock restrictor is removed, gather the other parts needed for the install. Part list is as follows: Stock BCS with restrictor removed (1G or 2G), .025 restrictor, vacuum "T" fitting, and a some vacuum line.
It is important you install a .025 restrictor after the turbo. To my understanding, the restrictor pill helps to get boost in the right ball park, and then the factory BCS regulates from there. Without the restrictor, the stock BSC will not be able to accurately control pressure supplied to the wastegate. I used a 1/8" .025 in-line orifice restrictor from Coast Pneumatics. Part # F-2815-251-B85, here's a link: F-2815-251-B85 . ECMlink also reccomends that welding tips can be used as a substitute: Shop Lincoln Electric 10-Pack .025 Contact Tips at Lowes.com .
Here is the .025 restrictor installed. The hose barbs on each end made it easy to install inline:
I made a little makeshift bracket to attach the BCS to. I'd recommend putting it close the turbo, in order to minimize the length of the vacuum tubing in the system:
Here's the end result:
After the install, have a buddy use ECMlink to activate the solenoid manually. While a helper activates the solenoid, feel it under the hood to verify it is working. After the solenoid is working, It's time to configure ECMlink for proper operation and dial in the system.
To get this system working without a MAP sensor, you have to do a little work around. Basically, if you install everything as instructed above, the only other thing you need to do is configure ECMlink as instructed below. You can set up this system without a MAP sensor, but it requires a little work around with the V3 software. I have included the How-To directly from Thomas Dorris, who instructed me how to get the system set up without a MAP sensor. Using a MAP sensor would be more beneficial, but again, it's not required for the system to function.
Quoting Thomas Dorris:
After you have everything configured, test the system out by establishing you have boost control. Follow this step by step, and you'll be good to go:bcssetup [ECMTuning - wiki]
After I got the system working, it performed flawlessly. The control is very precise, and I could adjust in increments of 1psi in most cases. You can use the system to tune in a spike, and then drop off; or even do boost by gear control. The features provided in ECMlink V3 are great, and you will have fun playing around with how the car and turbo respond to the duty cycles you set. Just be cautious not to over boost. A very small adjustment goes a long way, so don't input big number changes. If you guys have any questions, feel free to shoot me a PM.
Here are some additional links that will help with this install, and also tuning the system:

Edit: I've been informed the screenshots in Thomas' post weren't showing up for guys who aren't on the ECMlink forums. I uploaded the ECMlink screenshots to the site. If any of you guys still have issues seeing the images, please shoot me a PM.
