So I am wiring up my 7A to VEMS and have a few questions. For tach output do I just use one of the 259 ch? Also, would like to wire in the carbon canister valve to one of the misc outputs too for possible use. Does it matter what channel I use? Finally I remember hearing about needing a diode to be added to whatever high current channel I use for the IAC. Is this still the case and if so what size diode should I use?
Also, does anyone know how the factory ECU interacts with the AC relay and AC control unit and if it's behavior is able to be replicated on VEMS? I'm guessing that the ECU just bumps the idle up when the AC kicks in.
