Thread to share Edelbrock Pro-Flo 4 settings

[mrk5]

I thought it might be interesting and helpful if we started a thread to share what Edelbrock Pro-Flo 4 owners have been using since the system seems to have become so popular in these parts.

Please refrain from criticizing or critiquing unless it's asked for. The idea here is to just provide some information that might help others dial in there systems. There is not right or wrong answer.

I'll start with mine. I struggled for quite a while with mine wanting to die when shifting into gear when the engine was cold. For a while it would shift fine cold, but then wasn't doing it warm. It seems to be working well now and I think it's a combination of AFR, RPM, and timing.

Engine: stock original 350 in 73 C10
Mods: none, stock single exhaust and all
Other info: I live at 5,000ft elevation
Map: 5006_v65
Target Idle: 700 RPM
Idle AFR: 13.3
Cruise AFR: 15.0 (this is as lean as the system will let you go)
Acceleration/WOT AFR: 12.8
Fuel Modifiers: none
Acceleration Fuel: none
Cold Start Enrichment: none
Crank Fuel: I'm still playing with this, but currently I'm adding a little fuel (5-8%) at lower temperatures in the advanced tab. As of posting this, it's about 20° in the mornings.
Idle timing: 24°
Advance start: 1200 RPM
Total timing: 38°
Total in at 3000 RPM
Vacuum Advance: 12°​

With the TH350 (no overdrive or lockup torque converter) I'm getting an average of about 13mpg with a low usually around 12.25mpg and a high around 14.3mpg.

If anyone else is interested in posting their info, feel free to copy and paste my list above and just change the numbers where appropriate.

Can We ask questions about the system, or is there a better thread for that?

Some noteworthy updates:

v4.0.24 v68 of the tuner software will record data logs and is capable of forwarding said log to Edelbrock tech support
This revision is only available for Android software



That said, I have also spend a fair bit of time messing with tuning on these.
If you need some guidance and don't like the Edelbrock Forum, just let me know

You da man Bent ! I’m sure I’ll have questions if I ever get my 572 installed, it was Dyno tuned with a Sniper system and I switched to the Pro-Flo when it became available…

Yes! @Bent77 definitely is a great teacher!
The MAP sensor in mine had no markings or numbers. Original to my system from 2018.
The truck has never been great, or consistently decent, IMO.
I was thinking about ripping things apart after my last trip up to 12K elevation.

I swapped a well used sensor off of an '05 Yukon onto it Sunday and things seem to be improving even though I have only driven it a few miles with a little idle time in there, too.
