I have the same ESC - love it! But I use the USB link lead from hobby wing. It's about £3 and lets you upgrade to latest firmware or modified firmware and the programming software is great. You set all your parameters such as turbo settings, timing, reverse, break power, drag break, etc. And the software is free & easy to use.
I know it's less portable so may not be what you're after but I think it's cool that you can plug your laptop into your RC car and change some settings in the pit!
