DESCRIPTION

Interfaces with the ThunderMax ECM to provide realtime data of the air/fuel ratio read by wide-band oxygen sensors installed in the exhaust system Data is processed in milliseconds by the ThunderMax, which makes instant adjustments to maintain the front and rear cylinder air/fuel ratios specified by the SmartLink software, creating a self-tuning system Modular design attaches directly to the ThunderMax ECM, eliminating any mounting hassles Allows ThunderMax ECM owners (version 4.0 and higher) to add true wide-band closed-loop automatic tuning System fits all 01-10 cable throttle control-EFI Harley-Davidson models equipped with ThunderMax (V.4+) ECM (PART #309-340) Requires exhaust system fitted with bungs for oxygen sensors Allows the user to program the desired air/fuel ratio for maximum power, maximum economy or anywhere in between Targets specific AFRs, which adjust as you ride Includes two wide-band oxygen sensors No splicing required, system simply plugs into the factory wiring harness for total closed-loop functionality Made in the USA Because of possible clearance issues, some aftermarket exhaust systems may require modifications or relocation of their O2 sensor bungs. Legal in California only for racing vehicles which may never be used upon a highway.
