Electronic fuel injection and ignition systems need to be updated as often as motorcycle manufacturers upgrade them. As a result of changes that Harley-Davidson has made to their 2014 models that use CAN Bus, “Twin Tec “Twin Scan 3” will not work on certain models without being upgraded. This upgrade is now available and you will need to return your existing Twin Scan 3 to them. The total cost, including return shipping is $25.00. Twin Tec will update the firmware, add a new wiring harness and instructions with a CD.
Include a note marked 2014 Upgrade, your shipping address and a check, or if you prefer to pay by credit card, include your phone number and Twin Tec will call for your credit card info. Parts involved in this upgrade are number 15300, 15301, 15400. Return address is: Daytona Twin Tec / Upgrade Dept. 933 Beville Road, Suite 101-H, South Daytona, FL 32119.
