Hi All,

I have a Braineack MS3X and i would like to install a MAC EBC.

I am having a little issue with the wiring and would like your help.

According to Braineack's manual i should connect my EBC to 4AF and 4X wires on my MAF connector as shows below:


and according to the following diagram 4AF (White/Red) is a 12V and 4X (Pink) is a signal:

So i connected one wire to the white/red and the second one to the pink:


I used the test-mode in tunerstudio to test the wiring:

I tried different frequencies and nothing, no clicking from the solenoid.

I then connected the one wire to the white/red and the second to the black and heard a click, which i guess means that the solenoid itself is OK.

Below are my boost control settings:


Any idea what could it be?

The other thing that i an trying to figure out are the vacuum lines,with no electricity i took a straw and blew air into port 2, the air went out via port 3 which seems to be right, so i connected the turbo outlet to port 2 and port 3 to the wastegate, this way if the solenoid fails the turbo will work with its wastegate, and when there is a signal it will navigate the air to port 1 (atmosphere)




did i get it right?

Thanks,
Rom

can you confirm our harness has a green/red wire going to 4P and not loose like the pink o2 wire was?

I will take a look, but while i will have it out from the car, could you please advise from what pin it goes to the the 4X, so i would install one if it is missing?

Thanks!

I meant 4X when I said 4P. should be a green.red wire labeled EBC or BOOST that goes from the ecu connector to the MS.

Pin 6 "Boost" according to the below pic is connected only to DB connector side:






Should i just weld it to 4X pin?

Thanks.

you must have an earlier one where i didnt start putting boost through the MAF connector as a standard. either run a wire out or try to add it to the connector at 4x. Running a wire out might end up being easier...

I've addded it to th 4X, now its working.

Did i get the vacuum lines right?

Thanks!
