I am a little surprised the HP system can't at least do some kind of modification bank to bank, how different are your readings side to side?
The Dominator can read and tune from two O2 sensors. The HP is only one. efiexpert.com
Yep but the left only or right only, or Both together averaged out.
The technology is fast enough and sophisticated enough that it can read each pulse as it goes by the sensor and know what cylinder fired it and adjust accordingly.
