The csv isnt really an additional injector. It is a cold start valve and is designed to be held open for a long time. It cant respond nearly as quickly as an actual injector.
I am interested in the timing deal. I want to run a turbo on my na motor, but only 7lbs or less boost. Just to clarify, I can lock out the mechanical advance, set the base timing around 18deg, and let the vac advance do the rest? Eventually I would hook up my megasquirt to control spark, but not right away if I dont really have to...
