Compu-Fire HDE-1 Ignition Static Timing…

For the EVO project I am using the Compu-Fire HDE-1 Digital Electronic Ignition. I used this same set up on the 1990 Sportster Project, it was easy to set up and so far it works well. I decided to do something a little different here for this post and do a video of the static timing, or setting the timing with the engine stopped, of the Compu-Fire HDE-1 ignition.

The Compu-Fire HDE-1 Ignition kit includes the ignition module and wiring, the trigger rotor, a socket head screw, a flat washer, terminal connectors, and a stack of small magnets (these are used to turn on/off the timing light in the module to static time the ignition).

Bike is on the lift and I already have the ignition module wired up on the bike. The red wire goes to one side of the coil (the side with the white wire from the wiring harness), the black wire goes to the opposite side of the coil, and the green wire goes to the VOES.

To get the engine to front cylinder top dead center (TDC), I removed the plugs, and rotated the engine till the TDC mark is centered in the timing hole. I verified that we were on the front cylinder based on the location of the pin key hole behind the ignition module, per the Compu-fire instructions.

Enough with the setup… you can watch the rest of the process…

Probably could retitle the video “Let’s see how many times I can drop the T-handle wrench” 🙂

The Compu-Fire HDE-1 Digital Electronic Ignition is really easy to set up. Hope the video was helpful.

One step closer to firing her up!
