On ANY race car and most hot street cars.......Yes, I use the Dominator ECU and NTK sensors. I think you need on O2 on each bank. I even have a Dominator on my boat. The only vehicles I use one O2 on are turbo applications and some milder combos I consider daily drivers. I have HP ECUs on my jeep and my tow truck. But I ALWAYS opt for the NTK sensor.

We(Holley) realize that many want a second O2 option, but don't need all the extra inputs and outputs the Dominator gives. Along those lines, we are working on an "add on" that will allow a second O2 on an HP based system. But I don't know where that stands at the moment
