Question 1:
First of all, in terms of a platform to run MegaTune, I was going to use my g/f's old 233mhz since it was free but it's all f'd up right now. So I plan on buying another laptop to setup and tune with... I'm thinking of a 300mhz with XP but will that suffice? I'd like to use a p-III but that also creates a jump in price and since I still have to buy aeromotive 1:1, MSD ignition box, and zeitronix WB I'd like to spend as little as possible on a laptop. I can probably get a 300mhz for less than $100 but a 500mhz pIII is gonna run over $200. Any suggestions?

Question 2:
Going to get the zeitronix WB, will this fit in the stock O2 sensor plug on downpipe? Any modifications needed to make this fit or work correctly?

Also, with the Zeitronix is it worth it to spend extra and get the display screen?
