You can use the different XiED AFR's to fine tune the closed loop fuel ratio on your late model HD ECM the same way you would change jets on a carburetor. As long as the IED is Certified for use on a bike, it can be installed. Years and Models marked as "YES" can use any XiED. Only the 2009/2010 Touring bikes are limited to the FL-XiED, ViED and AFXiED.

For riders wanting to make adjustments to the closed loop fuel mixture, we offer two variable mixture products. The AFXiED with its robust internal components including an integrated AFR guage and the simpler ViED.
