Dynatek2000-HDE Programmable Digital Ignition System DD2000-HD2EP

Well, it fit in the original location, plugged right in, looks factory and the bike runs. The bike I used it on is all stock so as long as it runs alls good.

I wanted to make my 883 run a little better, but since the engine is internally stock, I didn't see the need to invest in a single-fire setup, with new coils, etc. Single-fire does have a place, in engines that are heavily modified, specifically high compression with long-duration cams. But for most engines, dual-fire (firing both plugs simultaneously) works fine, as it has since Harley has been building V-twins. Actual dyno tests by NHRS and others have shown the difference between a dual-fire and a single-fire setup to be worth maybe one HP...so there is a gain available, but it's small...maybe it's worth it to you, maybe not.What makes more of a difference is what advance curve your engine is using, and this is the advantage of the Dyna 2000 over the stock module. The standard advance curve is much too aggressive, giving full advance much too soon for maximum power or even for good driveability at medium speeds. The Dyna 2000 has four different curves, and dyno tests on the same motorcycle and on the same day by the techs at NHRS showed a significant difference between advance curves. The best advance curve was the 4th and least aggressive one, that allowed a maximum of only 30 degrees total advance, and eased into that advance slowly instead of giving it all at a lower rpm. For details, see the NHRS website and look under "Tech Tips" for the article "Single-fire ignitions explained and tested.Another advantage is that the Dyna 2000 has an adjustable rev-limiter, while the factory rev-limiter is preset to 6000 rpm and cannot be changed. The Dyna allows 6000 to 7500 rpm in 500 rpm increments. So if you really are interested in going faster, and if your engine can handle higher rpm, you can set the rev-limiter higher.Installation was very easy, just remove the three screws holding the triangular cover over the module on the left side, near the top of the shock absorber. Remove the two screws holding the module itself, and unplug the cable. Mount the new module and plug the cable in. If timing was correct before there is no need to reset it. I enjoy how my Sportster runs with the Dyna...it didn't run badly before, but it seems to idle better and run better at intermediate speeds, particularly in traffic, since the ignition doesn't need to be so far advanced at those speeds. It feels more mellow, and smoother, somehow.

Perfect fit for '93 sportster

This unit will not do single fire. The description is incorrect. Only the 8-pin,more $ unit will do single fire. The description of using two coils for single fire is misleading and wrong.

No hassle install. Runs like new. After all first one was 25 years old.

Worked perfect for my 1984 FXRP. You can not find the stock ignition module for these old bikes but this works.

Put this in my 1997 Heritage Springer (EVO engine), with a Andrews EV-27 and S&S Super E carb. Huge difference in performance. The only fault with this module is that the indicators and switches are on the back, unlike some other modules.
