I was wondering if during warmer weather, you guys ever try to richen up your air/fuel ratio, or do you try and lean out the mixture year round like some people do during colder weather. I'm playing with leaning my LTs about 5% right now, but I don't know about doing this during warmer weather, when our cars usually get less timing and less fuel. This MAF tuning rookie will appreciate any help.

I haven't played with it like that yet.
I know the maf sensor will detect the less dense summer air and match the fuel to it already, without having to try to compensate via the maft.
The less timing is another thought though... I guess if you were getting knock retard, a slightly richer mix would help with that. But the less timing would actually be less likely to get spark knock...
So, the answer is, I don't know. But at least it's an answer from somebody?! :)\'98 A4 Camaro v6->v8 conversion, and STS kit next<br />v6: 13.6 Powerdyne, 13.2 150 shot, 13.8 120 shot, 14.3 85 shot, 15.7 stock<br />v8(na): 12.18@113, 392rwhp<br />Moderator on <a href=\"http://www.mtfba.org\" target=\"_blank\">www.mtfba.org</a> and <a href=\"http://www.frrax.com\" target=\"_blank\">www.frrax.com</a> (Road Race & Autocross)<br /><a href=\"http://community.webshots.com/user/johnduncan10\" target=\"_blank\">Car pics</a>, <a href=\"http://www.trscca.com\" target=\"_blank\">TN Region SCCA</a>Comment
