3 things that are mainly happening: 1) brainstorming catch can plumbing/install ideas. work in progress. 2) installing
AEM TRU Boost X electronic boost controller/gauge. 3) installing
AEM X-series Wideband UEGO AFR sensor
These three things are results of me getting to items that i've wanted to address, but have just not shelled out the money for yet. The catalyst for doing them all now was the boost leak/vacuum leak that my tuner is claiming I probably have. I bought a
boost tester from amazon, hooked it up, and went hunting for bubbles while armed with a spray bottle full of soapy water. I checked the intake, any hose connectors from the turbo, boost controller, manifold, valve cover, etc... (I think I even checked the brake booster vacuum line, but now I can't remember...). The only thing I found was a significant "Leak" coming from my ZZP manual boost controller that came with the turbo kit. However, It's from a purposely placed ventilation hold on the barbed output from the controller to the wastegate. I've noticed that screwing in the adjustment screw on this controller seemingly does not affect my boost. I don't know how the boost controller works, perhaps i'm missing a check ball inside, maybe it works fine... IDK. I just decided to get rid of it and press forward with the AEM boost controller like i was planning to do eventually anyway.
Since I ordered the boost controller, I decided it was time to also buy the wideband O2 sensor. I know this car is running RICH (as intended currently by the tuner), but it bothers me that I can't say how rich. so... better data out is going to equal better tune in my case. Since I have to get this data to the tuner via HP Tuners, I also ordered the
HP Tuners Pro Link cable... what's another $75 toward the boost and wideband setup at this point anyway. This cable will hook up to the HP Tuners OBD2 module (I have the MPVI3 version I believe), which will enable the tuner to access the information from the boost controller and wideband easily.
The electronic boost solenoid is going to be mounted in the middle of the firewall, above the gas tank. I am going to place it here because that allows me to use the provided wiring harness without running any extensions for power. I started by pushing a fishtape through the tunnel from the back of the car. After some careful pushing and pulling here and there, i got the fishtape through. Then, I taped the harness and pressure hose to the fish tape end and pulled it through the tunnel toward the back of the car. All went easily.
I wanted to pull the wideband harness through in the same run, but I'll have to pull that through the tunnel, in the opposite direction since the O2 sensor connector is so massive.
I believe I have an unused key-on power source that is folded up and ziptied to my chassis near the steering column. I'll double check that this is key-on and use that for both the wideband o2 power and the boost solenoid power. I'll splice the power in near the gauges and also put the appropriate fuses in line there as well.
I borrowed
Rauq’s 3d printed double gauge cluster design to mount these gauges above the steering column. Had a friend print this for me, I’ll pick it up soon and see how it fits up.
I'll need to find a friend to weld the stainless o2 sensor bung on my exhaust, because I don't have that capability, but otherwise I don't think this project will be too complicated. Oh, I had to buy another
02 sensor bung, which I got from amazon here.
