MSM EBC and Boost creep on MS3PNP
 

Hey everyone,
I am having an issue with my MSM. After installing a Kraken low-mount kit I have come to a couple of problems with the EBC and boost creep. So first off, I wired the MAC solenoid to the existing wiring on the MSM boost solenoid (in front of the valve cover), I followed MS instructions on which ports to use (2/3). So my first issue is that when I turn on the boost controller in TS I get an error message that the pin is already in use (High Current Out 2), however, this is the way it is configured from the base map DIYAutotune provides so I'm confused as to why I'm getting the message when it's wired to the stock solenoid wiring. The second issue (which I suspect is related), is that my boost is spiking out of control (the highest I allowed was 15psi) when the solenoid is plumbed but turned off in TS but when I plug straight into the WG actuator with no solenoid in between I get a constant 8 psi. Now I blew on the solenoid and there is no restriction both when the car is on and off. What can be causing this?

Any insight is appreciated. I looked everywhere but only found one other person that had the same issue but don't know how he resolved it (the interference issue) and another describing the same issue with spiking im having but that post had no replies lol. Again any help is greatly appreciated

I had this exact issue with my MS3PNP as well. Also tried switching the hardware and tune configuration to run EBC off the option port, but never got that to work either. It frustrated the hell out of me for many weekends of trying to get the EBC working, but I gave up and I've just been running with MBC for years now. Interested to hear if anybody has any actual insight on this who can help you get it resolved.
