The current HPI speedo that ive been testing is a one touch set up. You then have a seperate unit that you plug your speedo into to change your settings.
The only time you need to use a laptop is if you want to use the turbo boost. You download the softwear onto your laptop and programme your speedo from your laptop.
Like i say this is only needed if you want to run the turbo boost, otherwise you set up the speedo just like any other.
Again ive found the speedo to be second to none, so just think how good the final production version will be!
Defo worth the wait
