So with the wide band.
Warm idle AF=13.9
warm Cruse af=14.3
warm acceleration=14.3
warm WOT AF=11.3
Soooooo would seem that it is currently running a wee bit rich.
Thease WOT numbers also gell nicely with the narrow band &volt meter wide open throttle numbers.
Next I am going to check fuel rail pressure it should be 39psi, and the vehicle was stock as a rock when I got it so not really expecting any surprises there.
it has only been a few starts since the memory was reset so I think i Will do another run in a while to see if the other numbers change.
As for WOT as far as I see it my choices are:
1. Do nothing it is not a daily driver and you really do not spend much time at WOT
2. Some how get more air into the engine, I believe I have pretty much done all the easy/ economical stuff. next is porting the head, and that is not really ringing my bell.
3. adjust the map sensor voltage input down as described / explained by gojeep:

I am leaning to option 3 as the best way forward(have not really been thinking about it for that long though).
Ok anybody got some idears? see something I am missing?
