Cosmic,
thanks for looking that info up about A/F and GDI motor. It makes me feel a little better about the A/F ratio that im getting right now..... I had heard that the opt. A/F for a turbo car was 11.5 to 1[/quote]
no problem looking up the info, I enjoy sharing as much as I do learning about the cars we love. 11.5:1 is the a/f that many tuners use as a baseline, however stiochometric a/f for gasoline is 14.7:1 to achieve a complete burn (100% efficiency) which in a nutshell, is impossible since the fuel we get is not necessarily pure and when you toss ethanol and mtbe into the mix..... forget about it.
[/quote]Well actually the a/f's can be much much more varied now since we are running direct injection. Alot of DI engines run as rich as 6:1 and as lean as 32:1. Thats the beauty of DI

By 'alot of DI engines', which are you referring to? Any links to further read up on the latest on DI engines?? Thanks
