MSD Distributor + ATI Flying Magnet + MSD Non-Magnetic VR Sensor

1. Modify and install mechanical advance distributor. (See Modifying Mechanical Advance Distributor, in

this document.)

2. Install ATI Flying Magnet crank trigger. (Note that an adjustable sensor mount is not provided with the

ATI crank trigger.) Position the crank sensor to be near the middle of its adjustment range while being

in between magnet targets with the engine at TDC. Set sensor air gap to .040”.

3. Wiring – note that sensor wiring may be different from what MSD instructions indicate. The Infinity

ECU can only accept falling edge VR/mag wave forms. If in doubt, verify sensor signal with an

oscilloscope.
