Hello. New to EFI and just got a Sniper 4500. Can I use my MSD 85551 distributor and MSD Digital 6 box together with the 4500? Thanks.

In short answer, yes. But are you wanting to control the timing with the Sniper? The Sniper instructions are fairly straight forward for the Digital 6 box. Any more questions, please feel free to ask. -
In my opinion, if a Holley EFI user isn't familiar with the Magnetic Ignition Type "Minimum Signal Voltage" &
"Filtering" parameters (in System Parameters/Custom Ignition Parameters), then they have no business using
VR/magnetic pickup type crank & cam sensors. This is the problem with using magnetic pickup type sensors,
there's more tuning work/adjustment involved. Hall-Effect sensors are "set & forget", very easy to use.
The more robust Hall-Effect sensors are preferred because they're not susceptible to EMI/RFI interference/noise,
and their digital square-wave signal strength is consistent, regardless of RPM (unlike the VR magnetic sine-wave).
Also, the VR magnetic pickup signal is weaker at cranking speeds.
Another problem with using VR Magnetic sensors, is there's more tuning work. Hall-Effect is "set & forget".
The VR Magnetic Sensor Type "Filtering" & "Minimum Signal Voltage" parameters need to be programmed.

Hall-Effect: 3-wire, square wave signal (digital), pulse generation
VR Magnetic: 2-wire, sine wave signal (inductive), voltage generation

Thank you Sir. I have the download of the 4500 Sniper thanks to Danny. I picked up a Holley Dual Sync distributor, so I can plug & play with the Holley unit.Originally posted by thecowwatcher View PostComment
