I'll assume you already have a wideband O2 and controller(such as the Innovate LC-1), the datalog output on your ECU board and have already cut jumper J12. You can use Freelog (a free download, it comes with instructions in a readme file) and the Moates HondaLog / HULOG with a printer-style USB cable to your laptop. I also bought a DC-DC step-up converter to power my laptop from my cig lighter socket.
