Im going to have to dig though the storage bins for it, my wife tends to be a bit of a pack rat and lumps everything together in one big bin..I think the TMIC is also adding to the leaness of the A/F ratio..The techs at Areocomp said that at the moment its boarder line lean in the mids and after 4.5k it seems to richen back up some, where it really needs that extra fuel..You can see that in the curve for torque..where there is a bigger nit at 4.5k to 6k, so Im thinking when I have away to get more fuel into her, it should smooth that out more and pick up the mid range even more..Im sure the CP-E by its self didnt lean it a to much. The car has never throwen a CEL even with the currnet mods to it....

Hah, I know how that goes.........frustrating at times. :x

Well, if you ever get the chance, it'd be appreciated. 8)

I've no doubt getting a custom tune will yield some very positive results.

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 :)
