The Digital HPMobile is controlled by the Digital HP Mobile application (app) from your Android or Apple device which communicates with your Digital HP Mobile ignition box via Bluetooth wireless technology, allowing you to program the many features of the ignition system. The easy to use app sets your three rev limits, shift light, start retard, spark settings and tachometer preferences. Save and load multiple settings for quick change between Street and Strip modes. The Digital HP Mobile app's easy to read dashboard displays engine tachometer, an active shift light, and system voltage in real time. Pre-loaded with user selectable themes allows you to select the look and feel you want. Unique to the Digital HP Mobile are robust one touch security modes allowing the user to set the ignition system into a valet mode with reduced rev limit or completely secure the vehicle by disabling start. PerTronix Ignition Products recommends either the company's Flame-Thrower III canister coils (44001, 44011) or E-Core HC/HP coils (60103, 60100) for optimal performance on the street or at the track. The Digital HP mobile works with most distributors including points or electronic or with the company's new Flame-Thrower Billet Mag Trigger Distributors.
