the sniper sucks so much air I thought I had a vacuum leak. When you fired that engine off it sounds the same so I guess it’s supposed to sound like that

What's the part# for the purple adapter wire?

Is very good information

Wow

I have a new Holley Sniper EFI and am using it on a SBC with existing MSD distributor (with mechanical tach drive) and MSD 5900 Blaster Ignition box. The magnetic pickup wire pair (purple and green) goes from the MSD box to the MSD distributor. The Blaster box has the purple/green to the distributor, black to ground, red & orange to coil, and an unused white wire. What wire do I run to the Sniper ECU for RPM?

What are the different coils can use? Was looking at sniper coil (556-153) msd blaster 2 coil, or a sniper hyper spark coil(556-152) with a sniper super stealth?

How do I perform the requirement your mention at 1:22, and does it mean that you disable the rev limit function of the 6AL (Digital, in my case)?

you'd have to have the programmable one i would assume.. as for the rev limiter, remove it, leave it... don't think it matters as the msd won't be controlling the timing anymore once you configure sniper for timing control. to be on the safe side, just make sure the chip used is same or higher than the rev limiter you input into sniper..

If I have engine run on, will adding a diode to the small red wire fix that?

Do you not need to phase the rotor or lock out the dist?

not with a hyperspark. you do it all through software. just have to match physical timing to what the sniper sees.

How do you run a aftermarket tac if you are now hooking the sniper harness into the 6al box where the output for the tac is?

The should be a tach output both on the Sniper harness and the MSD harness you can use.

@@callofgeorge Not in the scenario that was shown in this vid. The sniper has *NO* control over ignition timing with this setup... You need a compatible distributor if you want to utilize all the benefits of EFI! Pablo, if you're using an old school distributor just run a vacuum line from the Sniper throttle body and adjust your timing manually. Your timing will be no different than when you had a carburetor.

Very helpful video. Questions though, I have an old MSD 6AL that isn't digital. Does it function and connect the same as the one you show? Also, can I connect the ign hot wires from both the MSD 6AL and the Sniper's to the same wire from my ign switch? Finally, what is the P/N of the cable at 8:03? Thanks in advance.

Yes, the 6AL box should have the same color coded wires and connects the same way. It is recommended that you have a dedicated (only one load) switched ignition source for the Sniper. So if possible connect the MSD box to another switched source. The Ignition Adapter (Purple Wire) comes packaged with the main power harness in your Sniper kit. Thx J

I have a sniper bbd with a 6AL CD box and a Pro Billet 2 wire distributor that is set to factory settings. I show good power at the cd box with a blinking light when cranking. The engine immediately fires and then dies, I have used the tach adapter wire and eliminated the yellow tach wire. The display read stall before starting and while cranking, it never shows any rpm. Setup wizard did not show an option for timing controlled or non timing controlled, I am using non timing controlled. ??

@HolleyPerformance

The 6014 box controls 8 individual coils. I think the only way you could add a CD style ign box to this set-up , would be to add 8 individual boxes. not very cost effective! Plenty of people are making 1000+ HP on stock LS style ignitions. Sorry, Thx J

HolleyPerformance I don’t think he wants it to control the ignition, just the fuel. I am going to be doing kind of the same setup (Ls engine, Edelbrock dual plane carbed intake with Holley sniper efi, older msd 6010 spark control, comp 212/218 cam). The msd 6014/6012/6010(or Edelbrock equivalent) will control the LS spark....but the sniper needs to see a rpm signal. From the msd box, do we use the tach output from the msd to the yellow coil input(-) on the sniper? Or connect to the violet/green crank signal?

I like to know how to do stuff beforehand, rather than figure it out on the fly. But I think it is connected to the purple wire, and configured as a CD box in the setup wizard...not not 100% sure.

I have the same setup. The purple wire plugs into the green/purple plug, and you run the purple wire to you tach output from the 6014 box

There has to be a way to do this with a stock HEI or any other distributor. I shouldn't need to spend an extra 1000.00 dollars to do this. Maybe an old Mallory with the same three wire hook up. Seems like there is something simple they don't want to tell us so we spend money on non needed components.
