This bit of info was completely new to me. Perhaps it will be new to some of you as well.
For years I had always been under the impression that if one had a flip chip, be it 2 bank, 4 bank, whatever....one needed to turn the car off to change bank selections via the switch.
See, I have 4 positions to choose from. Occationally I would have the urge to switch from my daily driver app, to my street NOS tune while I was on the road. More specifically, sitting at that red light and out of the blue a ramped up Nissan Skyline pulls up next to me.
I used to blow off such situations, or, embarrassingly turn off the car, fumble with the switch, and re-start the car in the position I needed to be in to arm the NOS tune.
I recently learned from Lidio that as long as all banks are full on the chip, one can switch tunes while the car is running. He has the idle kick up a bit when I select #3, as a verifying sound that I hit the right tune. How lovely to just keep the NOS tank valve open, and be able to flip from my aggressive street tune to a slightly tuned down NOS tune on the fly, at will, anytime.
The only kink in this scenario for me is:
My switch has like six positions. I can still flip on the fly, but if I flip to one of the non-existent positions, the car dies. That's no good at a stop light, but very handy as a secret kill switch.
I need a switch with on 4 positions. My eyesite aint what it used be.
