Addition to Smokem's AFC SIMPLIFIED thread. Now locked.

Since on the subject would anyone be interested in a system that controls the fallowing

AFC
multiple gates, electronic or mechanical.
could change tunes if you want the primary driven harder in one setting or the secondary driven harder in another,ect
data logs and adjusts accordinly

All of this would be based off of RPM and TPS. The system would be set up to be a live tune where its adjustable on the fly and all electronic. You could now havea very low smoke ppump vehicle that is tunable.

anything else you would like to see?
 
$679 from apexi and controls up to 29psi.

How user-friendly are they?
Could you upgrade the solenoid for more pressure?
I'm surprised that a diesel vendor hasn't capitalized on this. Fleece made a controller for vgt turbos, this should be a cake walk.
 
Has anyone thought of putting a micro switch inside the afc to signal full travel? Seems like a few guys are finding they never had full travel from the afc in the first place.

Pull it off the truck and put shop air to it is the easiest way to verify it is getting full travel. A lot of people "crank" the star wheel and hope they are getting full travel.
 
And if you don't have shop air.. A mighty vac works great. :Cheer:

boost would be nice reference as well (see my previous post).

However... any ultimately reasonable individual would suggest that a proper p-pump setup & AFC dial in would suffice.

Yes I know how to do that. I was thinking just a mini green led light that lets you know it's traveling to its full potential while on the truck. Probably not worth it, but at least it would let you know it's running to its full potential.

I always disassemble the AFC and machine or remove metal from 3 parts. Then I reassemble it with a slightly stiffer spring and forget about max travel ever being an issue. You will need a deep rack plug to realize the full benifit of a properly modded AFC. With a deep plug and properly modded AFC the rack will reach it's travel limit way before the plug stops it or the AFC reaches it's limit.

welp... there's your nitrous actuation switch to boot!

it would reference boost at the manifold and between stages.
It would also monitor drive pressure.
All this could be used to have a truck that is tunable.. only want 500 hp, adjust the gates and afc setting accordinly with a computer in the truck.
I would hope for it to make the truck smoke free or very small amounts of smoke. I think it would be fun to build but wouldnt be for everyone.
 
wouldn't the solenoid only operating 29psi be irrelevant since we'd be using it backwards? As a boost controller, is you set low boost the solenoid goes full open, which to us would = full fuel, the higher the "programmed" pressure, the "less" air we allow through aka less fuel. So if we peg the controller at 29 psi it would take that before the solenoid even allowed boost to the afc, and commanding 0psi would allow boost through instantly

That just confused me, did it make sense to you guys?

Yes, it makes sense to me.

I think that ultimately, an AFC with a stepper motor or linear servo would be best. But, these electronic boost controllers are already available. Why not utilize them? You wouldn't need a spring with multiple rates. You would have complete control over the AFC.

Hell if you were good at programming them, you could mimic different plate profiles.
