Differential girdle springs! Drawn reciprocation dingle arm!
I've got an old trusty laptop that I use for all of my datalogging purposes. For the Buells, I've got an old USB interface cable that has a Deutsch connector for mating with the DDFI-3 ECM and has worked reliably for over a decade, so have not ventured out to replace it with anything else. I tend to avoid wireless communications for datalogging as it's prone to dropping data packets. The cabling mess that I mentioned is usually associated with the wideband O2 sensors I'll have wired up, but it's not too bad.
