You need a Hondata s300 v3 (white board), KPro4 (white board) or FlashPro with Bluetooth for this app to work. Hondata Mobile connects to your Hondata engine computer over Bluetooth showing real time data from your vehicle. Check and clear check engine codes, view sensor data, and display of virtual dashboard.
Note that you do not need to pair your iPhone to the s300, KPro or FlashPro. You should use the in-application connect function (lightning bolt) instead.
