MBC how many clicks?

[LEE69]

Been kindly loaned a Forge MBC to see it help with my boost surge.
The car does boost to 21 psi but i'll set it lower than that to be safe.
Question is how many clicks is your's set too, as i want to get it roughly set up before i try it rather than spend ages on the road doing it.

it doesnt really work like that lee. you need the smaller spring fitted firstly.
then you need to drive the car, see what the car is boosting at, tighten or loosen it to suit. mine was setup on the rolling road.

 

[LEE69]

Not sure what spring is in it, i'll check.

 

[ibizacupra]

depends on spring fitted
question is too ambiguous

trial and error fella, start low and work up

 

[LEE69]

It's the softer spring even if i head for 11 psi least it's driveable lol

Ok tried it and it holds the boost brilliant but it's too high i keep getting fault code (below) (I started it on 40 clicks)
LG is saying 17.8 psi so i'll wind it down a few clicks and keep trying.
I have left the N75 in the TIP and plugged in my spare N75 to the plug

17963/P1555 - Boost Pressure Control: Upper Limit Exceeded
Possible Symptoms
Reduced power output
Limp mode
Possible Causes
Boost Pressure too High
Hoses/Pipes incorrect connected, disconnected, blocked or leaking
Charger Pressure Control defective
VNT (variable nozzle turbo): nozzles stuck
Solenoid Valve for Boost Pressure Control (N75) defective
Possible Solutions
Check Hoses/Pipes to/between Components
Check Solenoid Valve for Boost Pressure Control (N75)
Check / Clean / Replace Charge Pressure Control
Check / Clean mechanism for variable nozzles

Down to 30 clicks making 13.4 psi but still getting the 17963 code but it's so nice not seeing the gauge bouncing up and down!

is the forge unos quite easy to fit lee ?

 

[LEE69]

Yes a doddle mate
The two pipes going to the N75 goto the unos

ok cheers

Lee are you running it with the n75 valve.

 

[ibizacupra]

this car is'nt mapped is it.... so you are adding boost only?!?!

 

[LEE69]

No bypassing the n75
Yeah is mapped although you never liked the logs Bill.

I have blocked of the tip with a bolt and connected the MBC to the two hoses what attach to the n75.
I am getting no codes now and it holds 15 psi and no oscillating boost as per my last thread

Am I safe in using one of these at 11 psi until i can get the funds and get to Bill?

 

[sambryant]

mine is running inline with the n75 valve.


this is how bill set mine up to keep the car happy, no codes ect.

 

[seatcupramad23]

bloddy hell that looks confusing lol

 

[LEE69]

The car i loaned it off Bill set up that was using no N75.

 

[LEE69]

bloddy hell that looks confusing lol

Once you have fitted one it's childs play.

If in parallel you just splice into the pipes and keep the n75 as Seat intended.
