Smog pump/ emissions...
Ok, I've been trying to find info on how to wire up the smog control systems, and am not having much luck, from what I can tell, I need to use a PWM to run a relay that will open and close the relief and either the port or split air valve at 3000 RPM's. Which do I want to use? or does someone have some better trick?
Emissions here in Houston is about to become a PITA next month and my car is way overdue for inspection from being in the shop so long, so I really need to be able to pass emissions.
