Hello guys. I want to ask a question about boost solenoid. When i took my car, there was Blitz dual electonic boost control. I have very low boost(8-9 psi) and i think it is related with EBC solenoid. Now i want to change it to mbc because it is easy and cheap. As i searched it on internet, i understood that when putting mbc on car, the boost line is disconnected whle leaving factory solenoid for ECU. But now i have aftermarket solenoid. On the solenoid, only there are IN and OUT lines. How we get the relation between solenoid and ECU. If i put mbc, should i buy also stock solenoid? or will i just buy mbc and connect boost and vacuum lines to it ?

 

If you want to switch to a MBC you will need the stock bcs. It stays plugged in and you cap off the two ends. Then mount the MBC where ever you want and connect vacuum lines to their appropriate places.

 

In all honesty though I would ditch the blitz boost controller and go with a Grimmspeed EBCS.

 

I am wondering whether removing it can screw things up with the ECU or not. How the stock bcs is related with ECU? Where i need to wire it?

 

It will make changes, you will need a new tune asap. And the stock bcs plugs into the gray connector.

 

Ok thank you man. There is not any tuner where i am living. Probably i will drive 3-4 month without tune. Would it be a big problem?

 

Don't drive it hard. Don't switch over until you're ready to tune
