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.
- Injector drivers are normally populated with GenBoard/Manual/DDFlyback - make sure yours are too
- IGBTs (usually used for ignition) have internal clamping that provide an appr. 400V flyback voltage
- P259 have internal appr. 50V flyback
- stepper channels also have flyback
No flyback on
- WBO2 heater1 and 2
- SPECFET 0 and 1 (DRIVE_A and DRIVE_B)
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:
- when using mdh.. command for testing (take care what is connected, eg. a coil will fry) add hexa 80 to turn the signal on: eg. mdhf2 turns I259 output 7 (that is the gate-signal for the IGBT that drives Drive07) on, while mdh72 turns it off.
- when adding hexa 80 in configuration, the signal will be inverted.
- why is the dec. value in the table ? Is that used for anything ? -- I added that because Megatune couldn't give output in hex //Emil
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.
