On a 2001 Heritage, seems to work well, allows the use of regular when that is all that is available. A definite improvemant.

this thing works great so easy to program and install about 15 minutes and its done much better price than OEM and you don't have to take bike to the shop for programing I live in the UK and H D want £80 that's $136 an hour labour charge so very pleased on all counts with this a very big THANKS J&P

Installed on a Dyna Wide Glide and love how easy it was to program. My bike has been having problems with engine light coming on and off along with a misfire at the same time. The ignition module seemed to fix my problem and enhanced the performance.

works great very happy

Harleypats on 10/13/2012

After I installed, according to directions, my bike started up okay. Paying the extra dollars compared to stock Harley part is well worth it. I highly recommend getting this part instead of Harley-Davidson. If you get the H-D oem part, you have to tow/haul your bike a shop to have the oem part programmed.
