Ams 500 and External Gate question

[psycho6cyl]

Ok in my quest to keep things as simple as possible i want to make sure i will be hooking things up right. this is a street car witb some track use. Id like to use spring pressure on the street but when i go to track use the controller. So using diagram B idea can I use the map source to the inlet on the controller solenoid on the 500? or for accuracy it should be Teed off the turbo? My map is by glove box where boost controller is. figure use just that hose.

I don't sell or have instructions to a 500. A will require a lot more spring to get the same boost. You will have to experiment to find a baseline. There's no set in stone hookup that is 100% repeatable. For launching hard with higher rpm and lower boost a different config is used to supply pressure to the top of the gate with a very light spring used inside so boost can be reduced to the minimum on the spring then ramped in as needed and set to whatever the external source is regulated to. Typically using an increase and decrease solenoid which I've seen hooked up backward and engines destroyed. Keep a close eye on your logs and do light hits till its nailed down

thx Bison. if o run it like figure A will that give me solid boost or it can still creep. will be starting car w new motor setup etc and was planning on running a 9lb spring. curious if itll shoot higher. thx

Creep is caused by inadequate wastegate flow. With the turbo selected based on 80+ % of its mass flow potential then boost creep won't be an issue. It's when you try to run a turbo that can support 80lbs/min at 50 lbs/min.
