For any other general hardware. Can be OEM parts (Eg Coils, injectors etc) or anything more specific.

Tuner Nerd (TN Performance) released a knock control unit compatible with speeduino.
It could work with the flex fuel input, outputting 150hz when no knock scaled to 50hz when massive knock,
Not only reactive to knock but also has ability to learn knock happy zones, and send voltage to retard timing there only.

How is that compatible with Speeduino?

It doesn't have any Knock control firmware as yet.

You could use it for basic engine protection if you can set to change it's output high/low.

Speeduino flex input is a frequency input not an analog one.

Why?
It's not analog which you said the other device was!

Hmm. I was misled.

but a firmware update on the TN device could allow it to behave so. It was designed for the honda ODB1 neptune or HTS Roms.

Frequency mode vs volts mode.
50Hz = massive knock
150hz = no knock

0v = no knock
3.3v = massive knock
