If I'm installing a 4 bbl FAST TBI on the dual plane offy manifold, how should I adjust the secondaries to open? It has a Holley 20-122 adjustable secondary rod to go between the primary and secondary lever so you can adjust when the secondaries open. Sice this is a TBI and not a carb, would it be better to have them all 4 open at once and let the maps take care of the fuel, or set it up like a progressive carb? Have the primarie open only while cruising and the 2 primary injectors feed it, then when you reach a point, half throttle or whatever, have it set up like a progressive carb. If so, what would be the optimum point to have the secondary open, 30% throttle, 50% throttle, etc.? Im not even sure that the controler can even be set up to do it llike that yet. Im in the very early stages of going to EFI, and just trying to gather everything and all the information I need to get started. So far I've built the controller and loaded the firmware on it, and got the tbi and a few other pieces. I think this one is going to take a while..
