Description
Part #: 8623-MSD
Upgrading to an MSD Flying Magnet Crank Trigger Kit will deliver the precise and reliable signal that a high-performance engine requires. This kit gives you the ability to control timing electronically through a Holley EFI ECU (or other standalone engine management system/ignition controller). At the heart of the kit is the 3-wire Hall-Effect Sensor that is easier to set up, less susceptible to EMI/RFI interference/noise, and less likely to have false signals than other methods (Distributors and VR Magnetic Sensors). In addition, they are less prone to mechanical failure since there are no wear parts. With the included high-quality timing pointer and the use of a direct bolt-on, degreed balancer (ATI 917302 or 918852), you'll be able to adjust timing in the precise increments required for your LS Engine.
Features:
- Most accurate way to trigger your electronic fuel injection (EFI)
- Powerful magnets embedded in a 3/8" thick billet 6061-T6 aluminum trigger wheel
- 3-wire Hall-Effect Sensor that is not easily susceptible to EMI/RFI Interference
- Allows precise indexing by utilizing the 10 degree range on included timing pointer
- Easy to install much like traditional MSD Crank Trigger Kits (use with ATI Balancer 917302 or 918852 but is also compatible with 917264 and 917242)
- Rigid mounting that will not flex and cause timing fluctuation
