From memory, 7 years ago since I set one up.
SET - boost pressure that you want. Can be set in bar(kpa) or psi(?) but the format DOES NOT CHANGE ON THE SCREEN FOR EITHER.
So when in kpa, 0.90 is .9 bar. When in the psi setting, 1.30 is 13 psi
GAIN - this is how responsive you want the controller to be to fluctuating pressure. Setting this to high can cause over boost, think the max setting is 30%? Setting to low can cause big fluctuations in boost, so getting it right will keep the boost steady.
SET GAIN - this is the pressure at which you want the boost controller to first open/start controlling boost. Think there was a kpa or psi setting again. The car I used this controller was only a 4 cylinder with an internal wastegste and not a rotary but for 1 bar boost I think I had this set to around .75-.8 bar. Setting to close to your boost target can cause over boost, setting to low will increase lag time.
The warnings were insignificant in terms of operation of the controller and are merely just warnings, so generally set just above your boost target and if your worried about over boost, lift off when it makes noise and goes red.
Can't remember the difference in the two warnings settings.
Turn set, gain and set gain to zero when starting out.
Start with set and do a few runs till your happy with boost.
Adjust gain next by about 5% at s time to see improvements but watch as your boost may increase so reduce your set accordingly.
Once happy with then, do set gain. Again you may need to slightly reduce set and possibly gain a couple points as your adjust this, probably start about .6 bar if aiming for 1 bar and increase in small increments again.
I also had the wireless switch for changing between high and low, loved it!
