If you had a wideband O2, you could want to tune a NA car to something like 12:1 all the way across right? Same thing with a turbo car but just more risky? A buddy of mine has been messing with his SAFC2 in his sr20det 240sx, and I just thought it might be a good idea to help him out before he screws the motor up. God bless that guy, he'll spend $300 on a SAFC2, and run with a broken power steering pump, broken brake booster, broken a/c, a leaky radiator, and he will still talk of his next investment to be an equal length up-pipe.
