I need to set up EBC in my Brain built MS3x and I want it to be able to switch between wastegate pressure and a higher boost setting. I wasn't sure how to properly set that up and I'm having trouble finding it online. I know the boost controller fails to open so can I just put a manual switch in the 12v signal to the controller or do I need to use a table switching output from the MS3? I assume using table switching is the correct method, but I'm not sure where to pull an output from in the ecu/wiring.

 

i was doing wastegate / solenoid via simple switch.

switch inline between solenoid and MS on the ground. if off, solenoid fails open and you hit wastegate. switch on, and you control the solenoid.

 

^same here. Constant 12V to the EBC, other side goes to a toggle switch, which then goes to Boost Control output. A tableswitch would be possible to use two different boost targets and use the EBC for both, but not necessary if one of those is wastegate pressure.

 

I've done it also with two solenoids and with a MBC inline as well depending on your needs.

 

Awesome, thanks guys that seems easy enough. Thank you for the help!

 

I went a bit fancier. I used a rotary switch to make a 0-5v 6 position switch. Then used a table to blend boost control. So 6 position of boost from waste gate to max boost
