Really Really lean with Powershot?
I was running the Riva B1 wheel and no Powershot and it ran great. I didn't have a wideband hooked up but it felt like it was making good power and it didn't blow up.
I ran a best of 79.2.
I put the E1 wheel on it with a Powershot (stock settings) and it pulled much harder but really laid down up top. You could just feel it go flat. I lifted pretty quick and didn't push it until I figured out what was up.
I hooked up an LM1 wideband today and watched it go to 15:1 at WOT
I adjusted the cruise portion down a notch because it wnt down to 11:1 just off idle. I cleaned it up to mid 13s.
I played with the red (WOT) setting and ended up all the way at 10.
It's still at 14+ :1
I'm definately putting in a boost referenced FPR this week, but doesn't this sound abnormally lean for my setup?

I think normal to get that lean,without increase Fuel Pressure.
Any how so great number on B1 wheel.

With these big wheels (E1 etc) you really need to do several things to get enough fuel to the motor. The Powershot by itself doesn't cut it. With the R&D R3 reflash it is my uinderstanding this situation is improved.
