Go to section 2 if you are doing the installation with the Dual Sync installed in the engine.

NOTE: Make sure that the injector harness, BLUE Trigger wire (EST) going to your 6A ignition box and your ignition coil are

disconnected until you reach step 27.

1. Remove the cap from your distributor. Verify which direction the rotor / distributor shaft turns when the engine is cranking

(either clockwise, or counter-clockwise).

2. Rotate the engine to Top Dead Center of cylinder #1. If replacing another distributor, verify that the rotor is now pointing

at the spark plug wire for cylinder #1.

3. If replacing another distributor, disconnect all wires and remove the distributor from the engine.

4. Attach the Dual Sync Distributor adapter wire harness (part # 77101) to the DFI Gen 7 main wire harness, ensuring that the

ground leads are connected to an appropriate grounding point on the engine. Then plug both the CAM & CRANK connectors

to the Dual Sync Distributor.

5. Turn the ignition to the Key-On, Engine-Off position, and launch the DFI CalMap Engine Management Software program.

8. If you are running CalMap version 3.0 or higher, from the Ignition Type drop-down list, select Dual Sync Distributor or Hall

Effect equivalent, then press F10 and skip to step 15. If you are running CalMap version 2.0 or lower, complete steps 9-14.

9. Change the Crank Trigger Edge switch to the Falling position and press F10.

10. Change the Crank Trigger Edge switch to Falling and press F10.

11. Change the Output Trigger Edge switch to Rising, and press F10.

16. If no error messages were observed, exit the CalMap program using the File>Exit menu command, by pressing the
