Affects the initial boost response. This may vary depending on the ST.TYPE style
selected. Refer to page 26.
CONTROL: Maximizes the boost response to the targeted boost pressure.
Boost will rise faster by selecting a START value closer to the targeted boost pressure.
(however too hi of a setting can initiate boost spike)
NORMAL: In this configuration the boost controller will not improve boost response,
but will start controlling the wastegate through the boost solenoid from this boost
pressure value on. (this setting maybe ideal for already quick spooling turbocharger
systems)

(1) In a BOOST mode set up screen, highlight START and
press the SET DIAL to confirm.
(2) Rotate the SET DIAL to change the START pressure
value activation point.
* To cancel and return to the previous setting and the
BOOST mode set-up screen, press MODE.
(3) To program the START value, press the SET DIAL to
confirm (this action will bring you back to the BOOST
mode set-up screen).
If ST. TYPE is set to CONTROL, Boost Spike may occur when the START pressure
value is programmed too high. Boost Spike --- is a phenomenon that
unintentionally causes the boost pressure to overshoot the targeted boost pressure
before it stabilizes.
