THUNDERMAX EFI AUTO-TUNE MODULE
Features
- Interfaces with the ThunderMax ECM to provide real-time 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 01-07 EFI Harley-Davidson models equipped with ThunderMax (V.4+) ECM (PART #1020-0321)
- 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
- Target specific AFR’s 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
- Special Feature — you can alter and view live air/fuel ratios without a computer link using a ThunderMax digital speedometer — quickly change the desired ratio for power or economy
