Funny you ask, I just installed mine this weekend. Went in like a charm (other than me putting my plugs on off by one). She fired up perfectly at 10 BTDC and I tighten the distributor down. Even before putting in my 1st table she idle better than ever before.

After that, I put in my basic default data in the iPhone app and submitted my 1st table. I have more power across the board and I can keep my idle around 750. When I put it into gear and have AC on, the distributor gives a bit more timing. So I been able to shave 100 RPMs or so on my idle because of that.

So in summary - I love it.

For the record, I got the Black / Female one.

good enough for me I am sold

Re: progression ignition
 

if you have any questions for progression ignition, they have answered pretty quickly. Somewhere I read they were in California but I guess they are in Florida now. So I get responses in the early morning here in Texas.

My last question to them, that they answered earlier today was:

Re: progression ignition
 

Oh, my 72 C10 setup:

SBC 350 (Stock-ish)
72 Qjet Carb (rebuilt by Cliff's High Performance).
Automatic TH350
Power Brakes & Steering
A/C (converted r134a)
3.07 Open rear end
Gauge cluster was upgraded to have a Tach, which still coming off the coil. So no problems with the tach!

I am using full manifold off the intake tree behind the carb to go into the distributor - I had to split it off from the client control vacuum reservoir. This old 72 Qjet only has the one full vacuum port in the front for PCV Valve & EEC charcoal canister. I wished that vacuum port on the distributor was pointed 90 degrees and not straight down - its a right PITA to get the hose connected!

Re: progression ignition
 

I find it hard to think there isn’t a vacuum port on the front for your vac pot!
You could tee into the choke pull off hose instead.
You got a pic of the front of your carb?

Re: progression ignition
 

there are other ports but they aren't FULL vacuum. The progression ignition requires full vacuum, full stop.

The one on the side by the choke, I have always assumed was ported too. I suppose I should hook up my vacuum gauge to check it.

My '78 Qjet had more ports, one of which was full vacuum on the front (not including the normal one for PCV).

Edit: I suppose I should check each capped port with my gauge, so I am not spouting off lies!

Re: progression ignition
 

The bottom right one (choke side) on the front should be a manifold vacuum.

You're really making think I need to pull the trigger. I've been mulling it over for months.

Re: progression ignition
 

Color me wrong for assuming the two ports on the passenger side (front top and side) were ported. I guess the only ported one is the diver's side that you see capped in my attached photo.

Though to me it seemed the passenger top had a bit of a stronger vacuum, so I connected this to the progression ignition vacuum port.

Gee, I feel stupid as I should have connected all the ports to my vacuum gauge months ago.

Edit: This is what I have decuded with my gauge and how the lines are connected.

1. Passenger Choke Side to EEC Charcoal canister - full manifold but seems a tiny bit less.
2. Passenger Top (above fuel line) going to progression ignition vacuum port - full manifold.
3. Passenger Bottom Tee between EEC Charcoal canister & PCV Valve - full manifold.
4. Driver bottom, capped, Ported Vacuum.
5. Back of Carb (not pictured) connected directly to Power Brakes - full manifold.
6. End of ports on my 72 Carb

Re: progression ignition
 

What’s the vac used for on the distributor?
For a vac signal maybe!

Re: progression ignition
 

I had vacuum connected before, just off the intake manifold's two port tee (one to TH350 and the other to climate control reservoir).

I am much happier with this setup for sure. Nice to learn stuff properly, which is what I get for assuming sh*t! But I swear I read any vacuum port on the top / middle of the carburetor was ported.

Sorry, seems I kind of hijacked your thread - i didn't mean to do that.

Re: progression ignition
 

It's actually a MAP sensor.

Re: progression ignition
 

Did you get a new coil too, or keep the Flamethrower from your old Pertronix?

You're really making me think about this too... Once I get off my a** and use Cliff's rebuild kit on my QJet, that dizzy might just have to be next... a little pricey but it sure sounds like a big improvement.

Re: progression ignition
 

I asked that very question to progression ignition, they told me I could keep using my Pertronix Flamethrower Coil & Wires! So it was just dropping in the Progression's distributor and done!

I had bought Pertronix before over Progression because I was weary about it. Though now I have the Pertronix Flamethrower for backup!

Re: progression ignition
 

We've all gotten used to carrying a spare module for our GM HEI units. That's usually all that fails with them and it's widely available.
What would be the failure items, beyond cap and rotor, with this unit and are replacement parts readily available locally or will the unit have to be returned to them for repair?

Re: progression ignition
 

On their site, no parts listed for module replacements. I have sent in a query about this topic of replacement parts (yesterday). Though I assume it is just the module....

As soon as I hear back on that answer, I'll report back here!

Re: progression ignition
 

That looks pretty cool! Wonder if you could use that on a Holley Sniper, in place of the Hyperspark? Or would that be overkill?

Re: progression ignition
 

Well this is the response and I did ask "what if" follow up, if/when I get a response to that I'll post that too.

no sweat keep the info coming

Re: progression ignition
 

Really don't like this answer to the "what if / electronics do fail" but it is what it is.

Re: progression ignition
 

I've been running one for a year now with no problems. Highly recommend. In my case I needed more initial due to the cam in my SBC, without exceeding at total of 32 degrees advance. Almost impossible to change the amount of advance in a HEI.

Re: progression ignition
 

Impossible you say!
If I’d known that I wouldn’t have limited my mechanical to 12 degrees using a 2 cent screw and 20 minutes of my life.

Re: progression ignition
 

well i pulled the plug and have a new one sitting on the work bench in the garage

Re: progression ignition
 

If you have time please do a write up on installation and tuning. I have been looking at one of these since the thread started. Thanks, Rg

Re: progression ignition
 

Link to another forum with links to other forums about this product. Overall no negative reviews.

Re: progression ignition
 

The install is really straight forward, insure your engine is at 10 degrees BTDC and have the distributor pointed to cylinder 1. Start the engine and check the timing that you are on 10 BTDC and adjust as needed. I got so lucky I didn't need to adjust and locked down the distributor.

I haven't had any issues and love the darn thing. When out shopping for Christmas I used the lockout.

Not on one of our trucks but applies:

Re: progression ignition
 

Thanks Richard, I appreciate it. Nice video, and the tuning looks straightforward.

Re: progression ignition
 

I'm really thinking about getting one of these. I really like the idea of being able to disable the truck via Bluetooth. But then I get a case of the "what-ifs"... what if my phone dies... what if the Bluetooth link fails... what if my wife needs to drive the truck when I'm not around (not that she ever would)...

I'm probably going to end up buying one in the spring.

Re: progression ignition
 

looks like an interesting product. but I guarantee I'd forget my PIN and get stranded at Whataburger.

Re: progression ignition
 

Does your phone actually have to connect every time you drive your vehicle? I wouldnt think so, if so though its a deal breaker for me.

BTW there are worse places to be stranded than What a Burger haha!

Re: progression ignition
 

No, you don't have to be connected at all, only to change / monitor.

As for loosing the code, well don't do that after locking the distributor! Kind of like, it hurts when I poke myself in the eye ... don't do that either LOL

Though phone dying, breaking, getting lost - that would be a bit of bad luck!

Re: progression ignition
 

What do these things cost ?

They want you to return it for servicing "if" it goes bad ? That's not something I want to hear on a road trip

I tried to look it up and their website doesn't work , That's not very reassuring. Being an old school guy I think I'll stick with the basic HEI system that's been used for the last 48 years , This just seems like an expensive techie type thing , Loose your phone and your done ? :lol:

Re: progression ignition
 

Web site works fine for me with the link in the first post. On the home page scroll down and click on the Chevy box. It shows all of the Chevy styles available and the prices.

What do you do with any newer car if it quits running on the road? Either call a buddy if you are close enough, have him come and get you, take the trailer back and haul it home or call a tow truck. Not a big deal....

Re: progression ignition
 

I'm with Doc on this. When (not if) the pickup coil in that 48 year old HEI fails your done. Time to pull the distributor and completely disassemble it to replace the coil. Hopefully you have a spare HEI stashed behind the seat.
Or more a likely scenario is losing that key fob for that late model car while on that road trip. Be prepared for a tow to the dealership.

I'm seriously considering one of these for my 72 Firebird. Once you price out a rebuilt distributor or a quality new one, an aftermarket ignition system with a Rev limiter and retard contols, a distributor gear for a bilet roller cam, the cost of having a professional distributor curve done at least once, the cost is the same or better without the ease of adjustability.

And if your worried about losing your phone get an old cheap phone, load the program on it and hide it in the truck. It doesn't need to have service, just Bluetooth to undo the ignition lock.

Just my opinions. With them and five bucks you can buy a cup coffee most places. :lol:

Re: progression ignition
 

Yeah , Well , it's probably just too high tech for me . I'll just go back to points . ;) :lol:

Re: progression ignition
 

Just ordered one for my CJ 304. Hopefully it works great

Re: progression ignition
 

I’ve had mine for about a week now. I love it, install was easy

Re: progression ignition
 

Have you done anything with the tables? I'm not sure I would know how to adjust them.

Re: progression ignition
 

Ya, I’ve played with them a lot. I’m not a tech person and was very hesitant at first. But once you start playing with it, it’s very user friendly. Jump in and start with little adjustments at first, you’ll get the hang of it.
