yes, but it’s still going to require your ECU and some soldering work to make a nifty serial or USB cable to plug into an ecu header. And of course a laptop (or palm pilot). This is also assuming you already have a wideband setup.
Tell us what you do know/have and hopefully we can get you pointed in the right direction. But as Mike said, it’s VERY easy to be in way over your head when you don’t know what you’re doing. It takes a ton of time to learn this stuff, and even more keeping up with new hardware/software.
