I have the inovative tuneyourengine.com wideband 02 I did a few datta logs, and found that I am running between 14.5 to 16.0 air fuel.
thats one reason I got it on my shitty A/F guage it said I was leaning out at the top of each gear.
so hear is my question, I am trying to tune my car, should I try and get the A/F as close to 12.5 as possible? and just try to keep it their across the rpm band?
thanks for the help.

Keep increasing your afc % all across the lower and higher points. Didnt your car throw a IAT code at the dyno? If so, that is a reason why your air/fuel could be off so much.

I think my car was throwing TPS, VTec oil psi.
sometimes it throws a TPS at high rpm's, but I fixed the VTec.
also I think there was something wrong with the P72 that you tuned my car with, I had the CRX turbo with only 220 hp
I ran it at the track and only got a 13.9, so I changed the ECU8 to a P30 and hit I low of 13.0, but avraged 13.2, but I am running a little lean at the top of the rpm band,
so just keep adding fuel till it comes down?
thanks
