7lbs is 7lbs less that I gotta haul around no matter how you look at it, and its nose weight if you really want to split hairs.
I wont fail smog if I can generate the voltage I need. The smog guys don't know what the heck isn't there any more.
And the relay is the key, when the secondary air ground signal is sent from the DME it triggers the relay for the pump. Well I used that ground to energize a DPDT relay that interupts the front 02 sensor signal line with a voltage signal of my own, the DME doesn't look for a voltage swing that early on startup just a solid lean signal to show enough airflow from the pump. I have it close but just not there yet.
Not a big debater, just wanted some help with generating the voltage signal I need.
