TERCEL1: HKS Actuator + MBC

[alfradio]

Please forgive me if this has been addressed before...

I've heard from several sources that with an HKS actuator, a manual boost
controller is NOT needed because the HKS holds the boost pretty steady...

Here's my question, brought upon by varying weather conditions etc. which
have a direct effect on the amount of boost... It would be a nice thing, while
at the track to be able to raise and lower the amount of boost (dependent
on various situations) without having to fiddle around with the HOT ENGINE
and that tiny little "C" clip which holds the actuator arm onto the waste gate...

Would it be possible to set the HKS actuator a tiny bit on the high side
(if fuel cut is at 12.5, set it a bit higher and then use the MBC to trim it back
down? OR, is the vacuum produced in the intake manifold not strong enough
to effect the stiffer diaphragm of the HKS?

The HKS actuator is designed to be used with the stock set up. If you follow the instructions it will retain the HI/LO function on a EP. I've used it in this mode for years. HI become 15psi and LO becomes 10psi. You can now alter this to a minimum of 7psi on LO by adjusting the arm length.

The actuator sets base boost pressure. You cannot run lower than what the actuator is set at.
