How To Setup a Dual Sync Distributor for Holley Sniper EFI

Congratulations on your purchase of a Sniper EFI system. The Sniper EFI system is compatible with several popular ignition configurations. In this video I am going to show you how to properly wire and set up the system for a Holley Dual Sync distributor using the ECU to control timing.

Big help, followed your directions and it worked perfect 👌. Thanks

[colinaglae]

Many thanx, for your educational video on EFI !!

[Headsup]

Good job on the video! 2nd time today I've heard someone say "dabreeze" when trying to pronounce the word "debris". In English we use (deb-ree)!lol It makes me wonder if this was the same type of person that would pronounce "chassis" as (chass-is) instead of (chass-ee).. Just having fun, please don't take offense. Thanks again for the video!

Your chart with common balancer sizes and calculations is for 45 degrees instead of 50...

[SmokedTirez]

This info can also be used to setting up the Terminator X system aswell...

[frankburn]

Shouldn’t the crank be turned backwards to get to 50° btdc ca in the same direction like the video shows?

[QdotRich]

So if you have both, the dual sync distrubutor and the msd 6al digital box, do you select dual sync distributor or cd box for ignition type? Thanks!

Holly crap batman 😕, I wanted this distributor with my Holley sniper but this makes me want to keep it a little more simpler.

[johnc.wunscheljr]

why are you going 50 degrees before T D C all other sniper distributor videos say O degrees from T D C ??? and what are the 3 o rings for that come with it ??

So i have a chrysler 318 and when i set it to 50 on the balancer it dosent line up the distributor its pointed to cyl 7 if i set to tdc i can line up the rotor contact with cyl 1

Is there a Video showing The Stealth EFI and Dual Sync?

[GrandsonofstFerdinand]

Mine has never ran right :( my experience with the sniper and dual sync distributor was been so disappointing 😢

[JohnsCustoms]

This video and the manual want you to rotate the SBC crank "clockwise" past TDC. This did not work for me.

I decided to move crank to the 50 degree mark already printed on balancer.

Guess what?

Insta-fire !

I just ordered a Holley Sniper 2300 2 barrel efi system for my 1982 Ford F150 inline 6, 4.9 Liter motor. Do I also have to get this? Thx

[hfuklgrekf]

Wouldn't you want your timing to go up as rpm goes up wanting to get this but doesn't make sense to me u set static timing at 15 at idle and when you rev it up you want it to be at 15 so wouldn't that be the same as locking a regular distributer at 15

[metaxa]

how come it says learning and seems like it's not and engine starts to run like a bag of shit ? why it can't throw a fault code like simple misfire or oxygen sensor too lean or too rich? i thought it's easy installation and use and now i hear i need to f around with my fuel map on a laptop to use dsd with sniper ? how come it't can't find where the problem is ? i heard about ecu adopting to the cam or intake simple misfiring should be easy to tune . i put old HEI and she is running good again so mst be something qith syncing em all together. i'll try next year again

[johnb]

I know this is an old video, but it appears you have no oil pump installed in the eng? For the guy's that don't know; if you move the rotor to the location you want the #1 tower to be, and your distributer does not seat, you will have to sync your oil pump to your distributer pump drive pin. Also you never told/showed your viewers how to confirm the static timing.

[ScottDLR]

How does the MSD CDI box attach to the Dual Sync Dist? Is there a cable?

[AeroSS]

Blow off the manifold to keep debris from falling into the as the breather grommet is wide open.

565104 is for a big block not made for a small block which i need.
