You need a ThunderMax Autotune Closed Loop ECM System if you answer yes to any of of the following questions. Does your EFI bike pop? Spit? Start hard? Run hot? Deliver poor fuel mileage and performance? Would you like to have full control of your EFI system, freedom to make major or minor adjustments without a master's degree in electronics and a computer?

Combine the benefits of the ThunderMax ECM and the AutoTune Module right out of the box for optimum performance. The ThunderMax is a completely new product that replaces the factory module, not an add-on box or signal modifier. The ThunderMax is purpose-built to deliver uncompromising performance but you don't have to be a rocket scientist to install, program or make adjustments.

As simple as it is to install and use, don't be fooled into thinking that this is 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.
