What should I go with, I know NOTHING about either of them ,all I know is that my S-afc and 450cc are making me way too rich leaned out at -40% and -50% at idle. right now I'm running 9:1 a/f pretty much all the way across, at idle i'm a little better, but still in the 10:1 or 10.5:1 ratio! So, hondata and uperdata will let me tune it to the exact specs i've heard. WHat is better, I know that that uperdata is cheaper, but I don't know anything about it even after reading about it. and whats the cost of uperdata anyways, like total finsihed product cost?

Uberdata is esentially free isn't it? There will be the indirect cost of a burner, but thats about it.

what's a burner, a soder gun? and can I send out my ecu to get it done, or do I have to do it my self? It sounds really hard..is it?

If I go uperdata, do I get rid of my afc and 450cc, or just the afc and keep the 450's? planning on running 9-10 psi on t25, d16z6.

Keep the 450's, you can keep the afc if you want a fancy boost gauge and tach.

I would suggest heading over to the Uberdata board and asking around.

Let me give you my strong opinion. USE UBERDATA!!!!! The software is free, the options are great, and it really works! I actually just put my 440's in, burned a chip, and the car runs awesome (still need to tune it). I bought everything I needed off of Moates.net for $106. This included the Uber kit, which has everything you need to chip your ecu, and the Burn1 burner that you use to burn your chips. That's it. No $800 software, blue box, or anything else. If you know someone with a burner, all you need is $21 for the ecu parts to be shipped! As for the soldering, it seems to be a bit tricky but do-able. I had someone solder it for me only to find they f-d up. So I ended up buying all the desoldering/resoldering stuff I needed and basically did it myself and it works great. What ecu do you have? If you'd like I could probably chip it for you and burn you a base tune (might as well use all that soldering stuff I bought ). Let me know. But bottom line, I would go with Uberdata if I were you.

i'll go with the uperdata and sell my afc, I can probably get about $150-180 of ebay for it.

Yes UBerdata is your best bet.
