Re: progression ignition
 
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:

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!

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?

Rich72C10 10-25-2021 04:01 PM
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.

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

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

Rich72C10 10-25-2021 07:23 PM
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.

It's actually a MAP sensor.

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.

Rich72C10 10-26-2021 08:38 AM
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!

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?

Rich72C10 10-26-2021 09:18 AM
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?

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.

Our modules use completely different hardware than a stock type module. Our modules also don't create the internal heat that causes stock type modules to burn out. The microprocessor in our module monitors the coil current and adjusts dwell time very accurately so there is no excess current which turns into heat.

We do sell replacement caps and rotors and yes, they are stock replacements that you can purchase elsewhere. Thanks

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

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.

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.

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
