Just to say, no matter what you do, you have to physically check inductive delay, it's not reliant to only the pick type.

Digital rising denotes when the pickup is at the beginning of a 'window', digital falling is when it's at the end.

EDIT/Correction - I have this backwards, it should read: 'Digital falling denotes when the pickup is at the beginning of a 'window', digital rising is when it's at the end.'

For the most part, a crank trigger should be digital falling.

"When the sensor sees the edge of an “opening” or a “gap”, this triggers the sensor in a “Falling” manner.
When the sensor sees the first edge of the material or tooth, this trigger the sensor in a “Rising” manner."

In the example, for a hall effect crank trigger, inductive delay is set to '1'.

But that's an example, and you need to physically check.

There is no selection for 'Hall Effect' sensor, 'Magnetic' is used.

Thanks for the replies..

My Holley V5 won't allow me to access the Dwell window unless it's connected it seems, lame.

I have a Summit Ignition box so while I'll have the tuner run the show for now I'm going to do the Joe Simpson classes and make sure I'm on top of all this after this engine is completed.

Sounds like...
Crank = Type 12-1, Sensor Magnetic, Inductive 1usec
Cam = Dual Sync/ Custom? - Digital Falling

You should really upgrade to V6 Build 400, you may not get support if you call Holley, first then they will tell you is to upgrade. It also requires a firmware update I believe.

The 'dwell' setting is only available with certain ignition options, and custom. It's under System Parameters > Ignition Parameters > Custom , then it depends on the type of crank sensor option you select.

That image I posted before is offline and shows the dwell option. Change the type of crank sensor option and it will probably appear.

There are many bug fixes in V6, and feature updates. Surprised your tuner didn't recommend it.

Here's the V6 revision history:

https://documents.holley.com/techlib...evisionlog.pdf

It's pages long.

Scanned, CAD and prototype bracket made.
I hope to have the final piece next week and on the engine by the end.

Goal is to have the engine back on the dyno, all steps taken to ensure the tune sees on the money timing and then how to replicate for future Ponti EFI enthusiasts.

My bracket will be available in case Holley doesn't make a specific kit.

Ok brackets are on, the L bracket needs to be redone smaller as the stock crank pulley diameter barely touches the L bracket for hall sensor.

Getting closer, this looks like it'll work, I'll have a complete custom kit for us.....

Custom Ponti timing cover bracket
Custom Hall Sensor L bracket
Shims for bottom of L bracket for perfect centering of Hall sensor
Water pump and alternator spacers due to 12-1 wheel thickness pushing out crank pulley.

Watch, Holley makes this kit over the Summer after they see there's a Ponti market. LOL

Pictures coming soon after we get it completed, probably Jan 22nd week.

I'd really like to see the pics when you get a chance, I may go that route on my other build.

We're getting closer, needed many tweaks to the brackets for those of us with the stock crank pulley diameter.

When its done it'll be a nice addition to our community and hopefully cover a bunch of us. I'll evetually need info on if 68-69 timing covers are the only ones that have bracket holes in this location etc. I think there's a good chance only the main bracket holes would need to tweak for different blocks of the holes aren't in the same location.

I'll have details soon, pics and hopefully dyno data to help future installs.

I think the timing covers are the same from 69-79. Who would’ve thought that you using a different balancer and pulleys than me would be such a difference. I use a Moroso 3 bolt mandrel to drive my power steering and alternator. My set up is pretty common for a race car setup, hence why I didn’t have the pulley issue.

It’s great that you are making something that fits a wider range of applications!

Yeah, like I mentioned in another thread, the pulley setup is a deal-breaker for me. I have like $3500 in a Billet Specialties serpentine kit. But even folks with AC are going to shy away.

Being able to use OE pulleys will make it a more fluid choice.

That's why I got the setup from the guy I was talking about in the other thread, the wheel mounts on the back of an SFI balancer, same brand I'm currently using. The wheel needs to be perfectly centered, and balanced, to not impact balancer function.

Of course, technically, it invalidates the SFI rating, but doubt anyone would take a hit on it in a tech inspection.

The 80-81 301 timing cover has no timing marks, the whole standoff on the cover isn't there. That gives a person plenty of room to mount a pickup bracket in the OE location of the timing marks, and that is what I had planned to do when I was building the boosted engine. And they are available new.

Looking like I'll be able to offer a pretty complete bolt on 12-1 kit, I'll post back soon but I'll leave the sensor up to the customer, also I'm not really looking to be a retailer but it's looking like that's the case to pull this off.

4 bolt Pontiac 12-1 trigger wheel (7.25" diameter)
Pontiac mounting brackets
Spacers for water pump and alternator

My GTO used to be ac, those people probably won't go this route anyways but if so they just make an ac pulley spacer, done.
