Does the HP setup have a setting for the individual throttle blade system? I know my Megasquirt system has a mode for that individual throttle blades but I don't know what makes that different. What do you do for vacuum signal to the ECU? you have the cylinders all hooked together for an average or does it just read one cylinder?
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?
I feel you on the hood, when I went to a tunnel ram I went back and forth. Nobody could provide me with the measurements I needed to make sure things worked right(Hemi scoop or cowl). In the end I got a flat hood and cut a hole in it. I like the way it looks without the hood but it goes a little faster with the hood on.
The o2 reads one bank, from cold to operating temp the engine & everything grows, it causes the throttle linkage to change from side to side, in my case it causes the pass side to start running leaner the warmer it gets so I have to run that side a little richer, The HP has sequential individual cyl tuning, but as far as closed loop the pass side is on its own, so I set it up for closed loop after 1800rpm. on the vacuum there is a little manifold block that has small lines from each cyl to it.
