Default beginner ?

I have been reading quite a bit on diy tuning and have a general idea on tuning theory. I'm a bit low on money right now and can't afford a wideband setup. I already have an egt gauge and have a tactrix cable on the way. My question is, do you think that i can get away with flashing a stage 2 XPT map or a cobb map ( note: i have tbe and up ) without a wideband? I really don't have the money for it, plus i would rather gain some more tuning knowledge before tinkering with my ecu. I figure it would be based on the same concept as the flashing with the AP, i don't remember anyone saying that you need a wideband to use it.

Your playing with fire then, tinker with pulling logs and using the software. While saveing 200 bucks for a LC-1 Wideband. This will keep you busy for a while, plus you will learn whats about what is going on. By the time you have some dough for a wideband you should be have the jist of whats going on.

Using someone else's maps are a great starting point, but they still will need to be tuned to your car in the long run.

Im going to leave your AP comments alone for now I dont want to get flamed, nor do I want you to get flamed

The new wideband sensor does not replace any of your existing sensors, you ECU still needs them. The new sensor will require a bung to be welded in to the exhaust after the turbo and before a cat. A exhaust shop would be able do this for you probley for 20 bucks or so.

Oh yea, the LC-1 comes with a serial cable that plugs into your laptop to do your logs.
