Dyna 2000i-P

Reprogrammable Digital

Ignition System

For

Harley-Davidson Motorcycles

! DESCRIPTION

The DYNA 2000i Digital Ignition is designed to replace the factory ignition module and sensor used on 1983 and
later Harley-Davidson EVO motors. It is also an ideal upgrade for early electronic and breaker-point systems that
require a mechanical advancer. The entire ignition fits inside the engine in place of the cam sensor or point plate
and connects directly to the coils without the use of an external module.

The 2000i will operate in single- or dual-fire mode and features 8 advance curves and 4 rpm limits to fit a broad
range of engine builds and riding styles. For nitrous and turbo equipped bikes, a single stage retard is provided.

A tach output is included, eliminating the need for an additional adapter when operating in single fire mode. Two
diagnostic indicators assist in trouble shooting and static timing.

The 2000i can be easily reprogrammed with custom advance curves and rpm limits using the optional DIPK-1
programming kit. Engine run-time data can also be downloaded with the programming kit, allowing detailed
analysis of engine operating conditions.

! INSTALLATION NOTES

**IMPORTANT** Coil primary resistance must be in the range of 2.5 to 3.5 ohms.

**IMPORTANT** Carbon, graphite or spiral core type suppression spark plug wires are required to reduce
interference. Do not use metal core wires.

**IMPORTANT ** The 2000i requires the gold colored timing rotor used on 1983 and later EVO motors (HD part
no. 32402-83). The earlier silver colored cup will not work properly. Bikes originally equipped with points (except
distributors) or early electronic ignition will accept the later model cup without modification.

! DUAL FIRE INSTALLATION

Single plug: use Dynatek DC6-1 or stock coil. Dual plug: use two DC2-1 coils wired in series (equals 3 ohms).

1. Remove the stock ignition module. Remove the outer and inner covers on the cam position sensor. Mark the
engine case near the middle of the sensor. Remove the cam position sensor. The pins may be removed from the
connector housing by slowly but firmly pulling the wires from the rear of the connector.

2. Feed the wires of the 2000i through the hole in the engine case and seat the ignition. Rotate until the timing
pickup (nearest to the switches) is at the mark made in step 1. Replace the screws that held the cam position
sensor, finger tight.

3. Remove the wires from the coil. Use a test light or meter to find the white wire that has +12V when both the key
and the Run/Stop switches are on (later models have only a single white/black wire). Attach this and the white wire
from the 2000i to one of the primary terminals. Attach the pink wire from the 2000i to the other primary terminal.

4. Tach connection (if equipped). Attach the pink wire from the tach to the 2000i green wire with the large (.250)
blade connectors. If the bike had only one pink (or pink/black) wire at the coil, connect this to the 2000i green wire.

Do not connect the 2000i tach wire to the coil or damage to the ignition may result.

5. Remove the wire from the VOES (Vacuum Operated Electric Switch). Connect the 2000i purple wire with the
small (.187) receptacle terminal. If the VOES is not installed, see the tuning tips on the last page.

The blue wire is left unconnected. If there is no tach, the green wire is left unconnected. These should be folded
back and tucked into the harness sleeve. The unused stock wire harness can be removed or taped up.

6. Skip to the "Configuring The Mode Switches" section of these instructions.
