My tunable engine management comes on Friday to replace the standard stage 2 map i've been running, so i've been digging around for materials to bone up on this stuff and came accross the following link.

if you havent already, check out www.wrxhackers.com and also read mick's quick tuning guide at http://www.pdxtuning.com/utec_tune_guide/UTEC_Quick_Guide_12_02_2004-notes.pdf
it was built around the utec but is by far the best thing i've read on tuning basics.

I gave that article a quick read and it seems to cover most of the basics for tuning... Do you have a wideband o2 setup in your car criz? If not I wouldn't really rely on the stock o2 for properly gauging your air/fuel ratio. Might be worth the money to hit up a dyno with a true wideband. I always tune for an 11:1 af ratio and then mess around with the timing settings trying to maximize timing without getting any knock. Street tuning is a little more difficult without a wideband. Good luck and let me know if you need any help!

I was going to rely on the stock wideband (it reads 11.1 -> 20.3) although I am looking into either the AEM or the LM-1... I like the AEM since it is a gauge solution... not sure though...

thanks for volunteering to help... I may take you up on that... you work for alcohol?
