Vigilante Flash is the first Android (now compatible with Apple devices) based tuning application and performance device that combines Scout data monitoring capabilities with custom performance tuning solutions that provide better power, improved throttle response, superior mid-range performance and lower engine temperatures in your V- Twin motorcycle. Flash includes easy-to-use software that quickly tunes HD motorcycles regardless of the engine modifications installed by the factory, dealer or rider. You can select from a multitude of specific calibrations and store up to three tunes on Vigilante. The Flash Tuner requires an android phone or tablet, or a Apple I-phone or Apple I-Pad, or a PC which connects wirelessly using Bluetooth connectivity to make adjustments to the motorcycle. The Scout Meter requires an android phone or Apple I-Phone, but it can't make adjustments, it only displays information about the motorcycle on the phone. The EZ Tuner lets you tune the motorcycle and make adjustments without the need for a smart phone. Experience the difference with a Vigilante tune and unlock the hidden torque and horsepower of your motorcycle.
