Description

This product has an attached note. View Product Note

ThunderMax 50 ECM with Auto Tune Closed Loop System

• 88″ EFI engines only

• Have full control of your EFI system, freedom to make major and minor adjustments without a master’s degree in electronics and computers

• CARB-approved, street legal in all 50 States, including California, Closed Loop System - ARB Executive order # D-644

• ThunderMax is a completely new product that replaces the factory module, not an add-on box or signal modifier

• Purpose-built to deliver uncompromising performance but you don‘t have to be a rocket scientist to install it, program it or make adjustments

• As simple as we’ve made it to install and use, don‘t be fooled into thinking that this not one of the most sophisticated systems you can buy for your Harley

• Using the supplied SmartLink software and communication cable, you can adjust or monitor virtually every parameter of the system

• The ThunderMax makes sense in the long run as the system can grow and change as your engine does - just load a new map

• ThunderMax software, firmware and maps updates are free and accessible 24/7 with an Internet connection so you‘re only a mouse-click away from the latest available data and product support

• Backed by a 3-year manufacturer's warranty
