That is fantastic. What are you planning on doing for speed (MPH or KPH)?
I think most people will use Racepak's GPS for VSS. The other option is MS3 can broadcast VSS to the Racepak network, assuming you have VSS going to the MS3. If you look at the video in the original post, the gauge on the bottom right is labelled "MPH" and is displaying a simulated VSS signal from the MS3-Pro. You can edit the gauge labels in Racepak's software if desired.
Also, I concede that my video sucks. We'll do a more proper one later.
VSS fed from an MS3 is going to be more robust than GPS-based VSS. Occasionally my Racepak will struggle to find satellite signal for the first minute or two, and that would be annoying in a street car. If you have the option, use the VSS provided by the MS3.
Ben, where can I purchase this module? I don't see it online and guessing it is very new and most site will not be updating their database.
I might have 1 or 2 on the shelf -- firstname.lastname@example.org if you want to claim one. We became a full line Racepak dealer with this initiative, but it looks like we're not adding new products to our current website as our efforts are focused on migrating to an all new website.
I can get them on the site a bit sooner - but we're going to have a pro photographer get some pictures of them, so I'm waiting on that to get the Racepak stuff listed. But as Ben noted, email us at email@example.com if you want one right now.
