No one can explain it to you fully in one post. You are going to have to do a lot of reading on this matter.

I have a brief write-up on Fuel Tuning with a wideband as it relates to TurboEdit on my site. May help you understand a touch...

my friend just put a afc in his Talon Tsi,,,and he said it took a while but after driving for a few hours..he said it runs pretty good.. He said 3rd gear is usually the best gear to TEST then tune in..he said he would get on it through the gear then adjust it a little,, and change it every time...Any gear better to test it in.. or just through them all?

Don't puss out, get uberdata

Was he using a wideband for adjustments or pocket logger or whatever that junk is that shows fuel trims and stuff. AFC tuning without a wideband isn't a good idea.

Hey man u should really check into uberdata. It's not too confusing really. I mean, I havn't setup my own basemap yet, but I bought an ecu from projekteg, 150.00, with a good basemap. Car runs perfectly with 10psi. I'm running a JDM D15B, 14B turbo, 450cc injectors, etc.. Basically same setup as you I'd guess. The VAFC will be harder to use, I've seen a couple guys (including myself) blow a SOHC motor with vafc. it's a pain to use it, more than using uberdata. you should contact projekteg, and he can tell you too. I have seen both being used tho, the vafc was used for "fine tuning" i guess. But with the new ecu, car runs so much better than with vafc! Check into it before you commit to it. oh, and make sure you get the resistor box or inline resistors for the 450's.
