Removing Secondary Vacuum System questions.

[XfireZ51]

Mike,

I still have my throttle plates in the bores and attached to the actuating mechanism. However, the vacuum canister is zip tied open so plates are perpendicular and open at all times. The prom is modified to have secondaries open from throttle tip in. At TPS = Idle, secondaries are off.
Anywhere over that, secondaries are on in my cal. For me its easier to tune one set of VE/SA tables rather than two. VE LOW (Port Throttle Closed) is the one I use for idle conditions. All other driving conditions use the VE LOW and HIGH (Port Throttle Open) tables. Spark Tables are setup the same way. MPG isn't really affected because in either case, the motor uses x amount of fuel. It'll just be delivered by 2 sets of injectors rather than one.
As for the bypass, its the cost of the correct male connector for the Diff MAP harness. I already had one, so I would need to check on cost.
BTW, we tried my cal with Lgaff's 92 and it ran fine at the track. His secondaries are still operational.
