CHAPTER 16 DIGITAL OUTPUTS
16.1 Description
The E6H/E6M possesses up to two special purpose digital output channels (depending on
whether or not the ECU is operated in Advanced Modes), each of which may be programmed
to perform a certain function. Each output channel is a pull-to-ground style signal suitable for
switching solenoids, relays or low-power dashboard lamps.
Each channel employs a 4.0A peak / 1A hold current driver. This is suitable for driving most
relays, solenoids, and other low power devices. Do not connect any device which requires
more than 1 amp continuous current directly to the ECU - it will not operate properly. If you
are switching high currents, use a suitable relay, either mechanical or solid state, and control
the operation of the relay with the ECU.
A number of output functions exist within the E6H/E6M ECU. You may select any function
to be executed on any output channel, but there are restrictions on the number of instances of
a particular function, eg: a maximum of two wastegate channels may be selected to control a
twin turbo engine configuration. Following is a list of available functions to choose from and
their restrictions:
