orange EP Posted May 16, 2022 Report Share Posted May 16, 2022 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!

Adamw Posted May 16, 2022 Report Share Posted May 16, 2022 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. Quote Link to comment Share on other sites More sharing options...
orange EP Posted May 17, 2022 Author Report Share Posted May 17, 2022 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? ※1http://www.linkecu.co.jp/ECUConnectors.html ⇒ BSC-O Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 17, 2022 Report Share Posted May 17, 2022 Yes that looks correct. If you disconnect one of the hoses so that no boost pressure can reach the wastegate diaphragm, do you then get high boost? Quote Link to comment Share on other sites More sharing options...
