ThunderMax is an industry award winning, performance ECM designed specifically for EFI equipped Harley Davidson® motorcycles. This highly advanced, stand-alone tuning system utilizes proprietary AutoTune technology with wide-band oxygen sensors to deliver unmatched performance and rideability. ThunderMax comes 100% assembled, ready to install with no wire-cutting or splicing required. Simply replace the factory ECM and oxygen sensors, load a map, and enjoy your new ride!
* Upgrade on OEM # 41000057
Tech Tips:-
Exhaust Note: On 2010up Touring models, the OEM exhaust system has 12mm o2 ports. The factory 12mm exhaust system is not compatible with the 18mm ThunderMax oxygen sensors. Models with 12mm ports require the purchase an aftermarket exhaust system with 18mm ports.
