Description

***Currently, air cooled setups are the first to ship as liquid cooled bikes have more inputs and outputs not yet verified.***

Not Happy with your factory ECU going into limp mode while trying to drag race, or need to tune a NOS, turbo, or super charged application? This package may just be for you. The MaxxECU provides the ultimate flexibility on your Harley Davidson M8.

Mounting the ECU under the stock seat is possible sitting on the front edge of the rear fender, with adapter box in the stock ECU location (some plastic trimming is required).  Backrest will not work with the maxx mounted here.  With a saddleman seat, the front edge of the rear fender won’t work unless you modify the seat, you can however remove the ECU tray and or use a shorter than stock battery  (P.10S Lithium as an example, or the Harley Soft Tail Lithium battery) and the MaxxECU will stack on top of the ecu adapter box.
