| I'm in the planning stages of a TT swap on my slicktop. Building it "right" and not cutting corners is more important to me than making big power numbers (I've happily been NA for 19 years after all...). I'm planning on running Nistune with dual wideband O2 sensors. Looking at the Zeitronix options I was initially drawn to the ZT-4 since it is a nice compact dual controller with basic functionality, but they also have the ZT-2 single channel controller which also incorporated EGT connectivity and a 0-5v sensor interface. If I'm already planning on dual wideband O2 sensors, how much additional benefit will dual EGT readings provide during tuning? Will they provide additional information on tune robustness that wouldn't be apparent just from looking at the dual WBs?
