When I first bought the car, it had a HKS EVC-S and HKS FCD installed.
The car was running properly, boosting as it should with no issues at all. I decided that I would like to take the car back to almost original spec and so I began removing some of the aftermarket parts.
As part of this, I removed the FCD and the EBC completely.I reconnected the pipe of the turbo housing, to the left nipple of the actuator.
I also reconnected the pipe on the right nipple of the actuator to the TVSV. I reconnected the one wire on the ecu which had the FCD connected to it. Following this, I went for a test drive and noticed that it would only boost to 0.5 bar.
I then tried connecting a manual boost controller which I fitted in between the turbo housing and the left side of the actuator.
The test drive that followed showed that the car was boosting to 0.9 bar however it wouldn't hold that pressure, rather it would peak to 0.9 bar and then rapidly start falling off back down to 0.5 bar. I then remembered that the TVSV had to be blocked on the right side of the actuator, which I then did.
After this, the car went back to boosting to 0.5 bar.I found that adjusting the boost controller had no effect whatsoever after this.
I checked the blue plug and pipes under the inlet manifold and found them all to be connected as they should be.
The car currently drives fine, with no smoke or hesitation of any kind but only boosting up to 0.5 bar which it holds throughout the rev range.
Any help on the situation will be greatly appreciated!!
