boost control

[bikesbuiltbetter]

Can I use the 9 position switch to select different duty cycles and use it for selecting boost levels so I can change boost levels during a run?

Do you have any analogue user-specifiable inputs left over?
Because, without knowing what the 9-position switch is but assuming it's just a variable potentiometer with 9 fixed settings, surely you could run 5V through the switch/pot, use the user-specified input to read the voltage coming back, and manage your maximum boost based on whatever that voltage is?

I guess I should point-out that I've not properly started playing with this thing yet, my assumption of how you could manipulate inputs to control engine-parameters may be way off.

In case you've not already got an answer to this ... I've just been fiddling with it, and it doesn't look all that difficult. If you've not installed the ECU Manager for the M84 onto your PC, doing so & then trying to adjust stuff can tell you what it can do. In the boost control section you can set-up a table of target boost values according to different criteria; and you can choose input sources/channels for the axis of that table. So if you use, say, User 1 for an input-voltage from a 9-position variable-resistor, then run whatever voltage-level User 1 expects through the resistor switch, then your signal should be one of 9 equally-ish-spaced voltage-levels between 0V and that max voltage; then you can populate the table with the max boost you want to be running at each of those settings.

Have a play - it looks relatively straightforward.
