Works well

Works well with my Spec mode esc but whenever I try to connect my RSX Pro is says I need to update the app on my phone but there is not an update available.

Hotwire 3.0

Tekin has once again proven to be a leader in technology. This app is awesome and really allows you to tune your vehicle while on the track. No more waiting for the next round of practice. No issues reported and works like a champ. Easy to use and setup.

Works flawlessly! I have multiple HotWire3.0's and can easily transition from one to the next. Very simple to use with no problems.

Developer Response ,

Multiple HotWire 3.0 devices--- that's what we like to hear! Not just because we sold more than one unit to a customer, nope, not at all. We actually don't make much on the HotWire 3.0, its purpose is 'value added', meaning, we sell it as cheap as we can to make our Speed Controls more functional. The reason we like to hear this is because we have some BIG plans in the works for the guys that own more than one HotWire 3.0, you guys are gonna LOVE this when its ready....
