Socks Posted September 26, 2014 Share Posted September 26, 2014 The threaded rod on the actuator, is connected to the internal wastegate trapdoor. Which dumps boost when a set limit is reached. To maintain a boost level... As a base. Take the locking nut off and tension the rod so it just keeps pressure on the wastegate to keep it shut. You can then tighten it more and more to raise the boost. Or use a boost controller.. Shorter the rod/more tension - More Boost Longer the rod/less tension - Less Boost Quote Link to post Share on other sites
Gainzy Posted September 26, 2014 Share Posted September 26, 2014 Wind out to lower boost, wind in for more if you have good fueling mods on ct9 0.9 will be a good set check your boost gauge all the time there is a tutorial somewhere on how to measure boost level Quote Link to post Share on other sites
Glanzacoley Posted September 26, 2014 Author Share Posted September 26, 2014 Well before I bought a new turbo it would boost hard to 10psi then creep to 14psi few days head gasket went. Had it repaired then bottom end went knock about 20mins down road :/ it's got a hks fcd but I've been told to take that off straight away, Quote Link to post Share on other sites
Glanzacoley Posted September 26, 2014 Author Share Posted September 26, 2014 There was a massive crack in the wastegate port so I bought a pukka ct9 for £25 & decat & zisco mani just gotta put it all back together now. Would you guys reccomend taking off the fcd? I'd also like to take the speed limiter off what do I need for that? Quote Link to post Share on other sites
Glanza1996 Posted September 26, 2014 Share Posted September 26, 2014 Here you go mate http://dub-se7en.toyotagtturbo.com/useful_info/OTHER_PDFS/hksactuator.pdf Quote Link to post Share on other sites
Gainzy Posted September 26, 2014 Share Posted September 26, 2014 Yes take the fcd off put the stock actuator back on till you go for a better/safer ecu upgrade Quote Link to post Share on other sites
Glanzacoley Posted September 26, 2014 Author Share Posted September 26, 2014 I don't have a stock actuator haha couldn't I just set the hks actuator at a safe level until I get emanage? Quote Link to post Share on other sites
Socks Posted September 26, 2014 Share Posted September 26, 2014 As Gainzy Said... Take the FCD off... FUel Cut is to protect your engine. You should only be bypassing that protection if your mapping the car! Quote Link to post Share on other sites
Glanza1996 Posted September 26, 2014 Share Posted September 26, 2014 Set it .5bar if you want to be safe mate soo measure 128mm on your aculator and that = .5Bar or 7.25psi Quote Link to post Share on other sites
Gainzy Posted September 26, 2014 Share Posted September 26, 2014 I don't have a stock actuator haha couldn't I just set the hks actuator at a safe level until I get emanage?Yeah you could it's just easy wacking the stock one back on just make sure you adjust it correct, watch the boost gauge all the time Quote Link to post Share on other sites
Glanzacoley Posted September 26, 2014 Author Share Posted September 26, 2014 Cheers guys with regards to taking the fcd off do I just cut the wires or? This forum is actually better than Facebook haha:) Quote Link to post Share on other sites

Socks Posted September 26, 2014 Share Posted September 26, 2014 No... I believe it intercepts a map sensor signal... SO you would need to rejoin those wires... Quote Link to post Share on other sites
