Does anyone use a piggy back controler to tune the air fuel curves. hence apexi afc or something else. i really dont want to have to buy a 2000 dollar computer system for the car like fast....
I user the Tweecer RT. $500
For about $900 you can get the Tweecer, a wideband o2, and SCT Tuning manual, which will give you datalogging capabilities and everything you need to tune the car.

http://www.tweecer.com is where you get it, and yes you have access to hundreds of parameters within the EEC that you can change, Including MAF curves, and injector parameters. The documentation is lacking and you previously had to rely on the forums to learn it, but You can buy the SCT Tuning manual at http://www.modulardepot.com/product_info.php?products_id=178 It is really for the SCT software (Much more expensive) but the parameters are the same. As far as the wideband, I went with the PLX M300 http://www.plxdevices.com/products_M-Series-Controllers.htm With all of this you can tune everything you need without having to go to the dyno. You do need a laptop for all of this to work, but not a very powerful one though, so if you don't have on you can pick up an old one pretty cheap to use.
