S2000 AP1 Kpro - Safe inputs/outputs for W/M and Nitrous?

[glemmestad]

Installing a wet NX nitrous kit and water/meth this weekend on my AP1. I'm already running Hondata KPro v4. I do my tuning myself, but haven't worked much with KPro specifically.

I see a list of inputs (arming) and outputs (solenoid control); are all of these free game, or is it depending on whether certain systems have been removed (like secondary air pump, for example)? I see options such as E21 VSV EVAP Vent, E20 2WBS EVAP Bypass, E18 ACC AC Clutch, and B6 FANC Fan Control (leaving the full names here in case someone else needs to search on this in the future). Can I just pick and choose, and just tap into the existing wire (vampire tap), or do I need to cut and splice?

Also, assuming the mapping is according to the KPro manual, so that E21 (EVAP Vent) for example isn't actually on E21 on the S2000, it's on A4. Correct?

Thank you!

The conversion chart you have posted is correct as that is from our help file.

Whatever input/output you choose, you need to cut the wire so it no longer goes to the original location and is only connected to what you are wiring in.

I would recommend that you use the nitrous kit as a dry setup and allow the ECU to manage the fuel delivery from the nitrous parameters. Wet kits will not allow you to control the fueling via the ECU and could cause issues.
