it really seems like if you want to use the 4th gen tank and have your fancy emissions crap connected and working, you need to use an ls1 cluster. i'm sure there's ways around everything if you don't wanna do that. |
Why? That tells me the pcm feeds the gauge. I have not found anything on the opposite yet.
Al, good for you. EVAP is a zero HP loss, high gain emission control. Evaporating fuel is terrible for the air.
