GenBoard/Manual/DigitalOut/Table (2005-01-31 06:18:20)

This page list the outputs that can be used for GenBoard/Manual/DigitalOut configuration and testing.

Injector drivers are primarily used for driving injectors, but any (otherwise) free channel can be configured for any output. The same goes for all the drivers, including ignition and idle solenoid outputs.


For inductive loads

it must be verified that the chosen driver handles flyback.

No flyback on

so be extremely careful with these. It is easy to apply a simple diode onboard or in the harness to provide flyback if needed, but without it the FET dies (and maybe other things too) when inductive load is switched with it.

Note: the IDL output is only ment to be used with the ON/OFF type solenoids, driving the relay (max 350mA) that drives the valve. If you want to drive a PWM controlled idle valve directly it's best to use one of the free INJ outputs they can handle much more current (max 10A) and are equipped with flyback.

Notes:


Several injector outputs can be switched simultaneously

It is very important to note the difference compared to other outputs.

While configuring ...channel=47 means the P259 output 4 (labelled idle solenoid relay) is used, configuring 70 will not necessarily mean INJ H. 70 instructs the controller to look up the 7th element (starting from 0) from the h[0] line (h table, line 0). If that value is set to 60 (Mask 40+20), INJ G (mask=40) and INJ F (mask=20) channels will be used.

Note that there is no mdh.. column for the injectors, because mdh.0 does the same lookup procedure.
