EPnick22 Posted May 5, 2013 Share Posted May 5, 2013 right here it goes.... been driving my gt for a couple months now, i bought the car with an AVCR boost controller fitted and set up, the car has always ran .7 bar since ive had it, now ive settled into the car i raised the boost and duty, changed a couple things on the controller but nothing changed at all, the previous owner said the controller always worked fine. i tried adjusting my actuator rod (hks actuator) and nothing again..... is there something wrong with my wastegate? its a standard ct9 w/ internal w/gate. Ive seen a few things about the gate spring being worn out and holding it shut so it cant build the boost? Quote Link to post Share on other sites
whitestar Posted May 6, 2013 Share Posted May 6, 2013 The wastegate spring is in the actuator, so it should affect your boost when you adjust the rod length. Wastegate is shut when it builds boost, so a worn spring wouldn't hold the boost. Seems like the problem is with AVCR then? If you shorten the HKS rod lenght it should hold more boos anyway, was the spring worn or not, I guess. Quote Link to post Share on other sites
EPnick22 Posted May 6, 2013 Author Share Posted May 6, 2013 well even when i adjusted the rod it made the slightest difference to how fast the boost ramped up, but not a lot, it doesnt exceed 10psi, it doesnt drop or creep one bit, any ideas? Quote Link to post Share on other sites
EPnick22 Posted May 6, 2013 Author Share Posted May 6, 2013 surely it must be a boost leak perhaps if it wont exceed 10psi no matter what? Quote Link to post Share on other sites
EPnick22 Posted May 6, 2013 Author Share Posted May 6, 2013 quick update incase anyone knows (hopefully someone) when i plant my foot in first it hits full boost (10psi) straight away, same in 2nd and pulls like a motherf*ucking train, but i cant get any more out of it than 10psi even when i adjust things...

string Posted May 6, 2013 Share Posted May 6, 2013 i would try running without the avcr. ct9 outlet into actuator. when does your turbo hit 10psi? if its a boost leak you will know. 1. i would disconnect avcr and actuator and make sure wg flap moves freely. sometimes catch on gasket or inside of decats.2. connect ct9 boost outlet to actuator. no avcr. see what that does. play with length of arm.3. connect avcr back in and possibly play with settings.

EPnick22 Posted May 6, 2013 Author Share Posted May 6, 2013 wg flap moves freely ive already tested this, ive adjusted the length of the arm a few times to experiement, if the avcr was faulty and i adjusted the arm would it stop it from making that difference?

EPnick22 Posted May 8, 2013 Author Share Posted May 8, 2013 come on someone must have an idea! Quote Link to post Share on other sites
TrisK Posted May 8, 2013 Share Posted May 8, 2013 This is just for a test. But to check for boost leak/fault with actuator spring, disconnect the vacuum line to the actuator, and hoof it.You should be running unlimited boostIf you don't, it's actuator/boost leak/turbo faultIf you do, it's a avcr faultPs, if you have an fcd, temporarily disconnect it Quote Link to post Share on other sites
EPnick22 Posted May 9, 2013 Author Share Posted May 9, 2013 thanks dude, im going out soon so ill give it a try, ill keep you posted soon! Quote Link to post Share on other sites
EPnick22 Posted May 10, 2013 Author Share Posted May 10, 2013 update!!! unplugged my actuator from the boost controller, boosted straight to a bar first pull, i was like wutttt, so yeah im guessing its the avcr thats at fault, what exactly would be at fault? solenoid valve?
