Boost Control has never been easier
e MoTeC ECU’s offer unparalleled levels of boost control. In addition to having feedback
type wastegate control, various inputs can be used to regulate boost for certain parameters. For
example, when using a wheelspeed input, MoTeC allows boost based on wheelspeed and rpm - or
boost based on gear position and rpm. A multiposition trim switch input can be used to allow
the driver to manually select the desired boost level on the fly.
How can I use a Trim Switch?
e multiposition trim switch can be used in a number of ways. It is most commonly used to
trim fuel or ignition but can also be used to trim boost if the wastegate is ECU controlled or can
be used to select 1 of 9 or 11 different RPM limit levels on the fly without a laptop. Ask your
MoTeC representative how you can use a trim switch in your application.
