to run nitrous through hondata do you use a dry kit or a wet kit or it dont matter

 

Doesnt matter...you can activate anything you need to with the outputs and a relay setup.

With a wet kit you wont need to add fuel when spraying but will still be able to pull appropriate amounts of timing. With a DRY kit, you will be able to add fuel and remove timing as necessary.

 

how exactly does that work? Does it switch to a new fuel and ign maps?

 

You can set it up however you like. Simply read the hondata help files & review the software settings.
