New additional Injector Controller

[Peterson, Lew [Cont]]

Frank:
I am definitely interested.
Things I would like it to do:
Use TPS to sense WOT and therefore Open-loop (I hope), add a separate
wide-band O2 sensor (recommendations solicted) and a separate (from the
on-board 2 Bar MAP) 3 Bar MAP. The foregoing sensors would be used to run a
closed-loop power enrichment mode (AFR of 12.5) on the added injector.
You are wlecome to pick this concept apart, the dialog would be beneficial.
