As taken frm the INEX approved Digital Peformance Ignition Installation & User Guide:
Crank Trigger Installation:
Steps 1)-4) Assuming you have the timing rotor installed on crank with M10 x 25mm socket head cap screw torqued to 36 ft-lbs and you have 1/2" dia x 3/8" length spacers, M6x20mm socket head cap screws, and 1/4" ID flat washers (2 of each) used to retain crank trigger assembly to engine case.
Step 5) Line up 40° mark on the plate with the split between the two engine case halves and lightly tighten the cap screws.
Ignition Timing:
The LED on the front of the module is used to time the engine.
1) Plug in four pin crank trigger connector into the mating harness connector.
2) Plug in the module and turn on ignition switch.
3) Rotate the crankshaft so the 1-4 mark on the rotor is at about the 2 0'clock position. The LED on front of the module should be off. Rotate the engine forward(counter-clockwise) until the LED jus turns on. The mark on the rotor will line up with the vertical line on the plate when the pickup is properly turned. If the marks don't meet, rotate the rotor mark back to the 2 o'clock position and move the 1-4(right hand) pickup slightly. Roll the engine forward and check again.
4) Follow the same procedure for timing the 2-3 pickup using the 203 mark on the rotor.
5) Disconnect the power. This completes the timing procedure. The timing is now set for a maximum(or final) advance of 40° BTDC. The timing can be changed by rotating the crank trigger until the desired final timing indicated by the scale on the plate lines up with teh split in the cases.
I suggest you set your final timing at 36° BTDC to start.
Good luck! Mark
