How to set high Boost on LinkG4x ATOM Open loop


orange EP

Recommended Posts

Hello
I have a boost control setting for "G4x ATOM", but I can't set the boost to a high setting.
Setting Wastgate DC% to 100 only raises it to 0.7Kpa, which is the same as a stock engine boost.
I want to make it 1.5Kpa, how can I do it?
thanks!

If you cant achieve the desired boost with 100% DC on the solenoid then one of below probably applies:

  • Solenoid wired incorrectly - does it click when you do a test?
  • Solenoid plumbed incorrectly - see guide in help file:   Wiring Information > Miscellaneous Diagrams > Boost Control and Wastegate Plumbing
  • Wastegate spring too soft.
  • Exhaust manifold pressure too high.
  • A mechanical issue with the wastegate valve.

hi thanks for the reply.
Solenoid valve uses 3 port one (* 1).
The solenoid valve was connected by referring to the LINK manual.
port3 connected to turbine pressure.
port2 connected to westgate.
port1 has nothing connected.
Is this correct?
