that is cool that you are just fucking around... it is the BEST way to learn shit... but when you do decide to run a nice setup and you dont want to mess up your computer go with hondata, haltech, or the AEM Power FC... i have had Hondata and loved it and am now running the AEM computer in my RX-7, i will let you know what i think of it once i am done with break in on the motor and have it tuned...
