How To Build A Custom Timing Table - Sniper EFI

Timing control is one of the biggest benefits of EFI! Having the ability to have a specific amount of timing advance in each individual cell means your car will run smoother, use less fuel, and make more power!

This is exactly what I was looking for, someone to explain to us older carb and distributor folks how this new stuff crosses over... Awesome thanks 👍

I figured out the part that this video completely walked around that has so many confused. There’s an older video called “Individual Configuration Library ICFs” from HolleyPerformance where they’re talking about all the ICFs, selecting, disabling and so on. To save individual spark tables create the mechanical as he shows, then go to File, Export Config, and select the spark ICF box only and name the file for your mechanical advance. Then clear your table and build the vacuum advance table as he shows. When he says to bring up your mechanical advance table again go to Toolbox then Add Individual Config to select the mechanical spark table you built earlier then follow his directions from there on out. If you do it right, you’ll get the same appearing graph he did. Watch the other Holley corporate video I mentioned if what I said didn’t make sense.

For those confused by the two tables... What you don't see is the clearing of the table. In fact, notice that his scale is the MAP (kpa) on both. The vacuum advance is just an example of vacuum advance alone. To build the map:
1. follow the mechanical map creation
2. skip the vacuum map and pick back up at ~5:31 "Go back to your mechanical table and highlight the bottom few rows"

3. finish the fill in and you should be all set.

Note: I don't understand why they're showing a ridiculous 56 deg advance as a suggestion. I realize your conditions should never put it there but still. That looks dangerous to me so I'm not going to advance 20 across the board as the video shows. YMMV

Fantastic, I did this today with timing events that I know my motor is happy with. Total success, the motor runs so much better than it did with the basic timing map. Will have a look at it again once I have some miles on it.

This is a really well made video. It is very helpful.

[roscioa]

Nice video. I might have to get the hyper spark for my car.

What do you use for a hyperspark distributor? A blend of mechanical and vacuum?

[michaelrello]

How do you get to the overlay that comes on at 6:22. I can’t find it anywhere

[kublicron]

Would this work on a turbo application as well?

[Wilson_Racing]

If i'm using the full Hyperspark kit, do I need to use both the vacuum advance AND mechanical advanced tables blended together?

[rjbradleyjr]

How do you go between tables?
Manicanical and vacuum advance?

[armygreenfj]

Does the Holley Sniper 2 require laptop tuning?

[johng]

I get lost at 4:55, when he starts to make the vacuum advance table. He seems to toggle back and forth between vacuum or mechanical tables. I cant seem to be able to start a vacuum advance table. Any help would be greatly appreciated.

[schaefer]

I’m missing a major step here at approximately 4:20 or close to that in the video where he hits something on a drop down and then has a fresh white graph to start with! Obviously you have to have a new blank graph to start, how do you get there?

[oldscutless]

will dis how to work the same way with the terminator x

[AlejandroMartinez-plnp]

@Holley is there a video on how to tune the AFR tables? I followed your instructions here and my car runs a whole lot better (It was ok before but I'm happier now with the new tune) but I can't find a Holley video for setting up my AFR tables. Any help is appreciated. Thx.

[makaylahull]

can someone send me the link for this software?

[literfox]

Where your idle timing will end up is much higher than you initially set it to be

[callofgeorge]

where is a link to download the software???

[davidallen]

Is the software compatible with a Mac laptop?
