KO3s turbo pressure

[mac_GTI]

i have a re-mapped golf gti turbo with the KO3s turbo, recently put a manual boost control on to by-pass a boost problem. ive been looking up the best, safe boost pressure to run at but have ended up confused with people saying 0.6 bar and others up to 1.6bar. I currently have it set at 1 Bar exactly. any help welcome

What map and what is the spec?

IMO I would never run a MBC on a golf 1.8T as you will melt pistons etc but the boost pressure is as follows,

0.6 bar is stock

1 to 1.2 bar mapped

its mapped for a KO3s turbo, de-cat sports exhaust, sports filter, dump valve etc

Manual boost control is a silly idea, why not sort the problem before you break something.

You wont melt a pistion on a 1.8T engine the ecu will fuel for the air drawn via the maf. (only if the fuel pump or lambda sensors are faulty will you melt a piston)  depending on engine code you will get throttle or N249 cut  as you try to rasie the power.


To turbo your boost up you really need to log the AITs and timing.

Weren't the AGU engines the only ones with no fail safe as I remember the AUM's will override the throttle to cut things?

Also what is the best way to wire the MBC in, to bypass the n75, run it in series or parallel?
