Just wondering if anyone know which uses more pressure and also could you stack a volumizer with a TST box I know you can stack EZ with TST. Thanks

 

Ok does anyone know who makes the Volumizer.

 

I believe the Volumizer has the higher pressure since is capable up to 100hp. The EZ is 70hp max (not counting the secret level 5).

Volumizer...

 

Volumizer also adds some duration and/or timing at its highest level, so not 100% pressure at level 3.

 

There is not DIRECT timing or duration with the Volumizer...look where it hooks up.

 

The Volumizer is pressure only. Connects to the MAP and fuel pressure sensor.

The volumizer that Im looking at does not look like the one in that pic and the guy says that it is made by Bully Dog it looks kinda the same but has more connectors.

 

Quote from DLeno from his fueling box summary:

"Pressure/Timing” boxes raise fuel pressure and perform boost fooling like pressure boxes do, but also provide injection timing advance via direct connection to the crank and cam sensor. By introducing artificial delay into these analog timing signals, the ECM is essentially “time fooled” into advancing the injector opening event. Approximately 30-40HP is available via timing alone without additional fuel, depending upon how radical the advance. In order for the ECM to be happy, a very precise phase relationship between the crank and cam signals must be maintained, and for this reason, manufacturers have been struggling to achieve successful timing advance on the 3rd generation trucks without setting an engine code.

Within the pressure/timing box category, the PDQ Volumizer is unique because it, like the Ramifier, is able to re-map the MAP signal itself to new values. This allows greater low-boost fueling, a stronger low end, and more smoke."

 

The old 355 degree crank sensor position trick is lame at best. In order to provide true timing and duration one must take over directly driving the injectors while providing a flyback voltage to the ECU to keep it happy while lost in space.

If it does connect to crank/cam sensors and they can actually get that to work on the 04.5 and up without damage or MIF's then they are only able to do timing and no duration and the timing they are doing is a rotation out because they need the signal first before they can modify it. They can't predict the timing in other words. That's why driving the injectors directly is the best way. I would definitely stay away from any box that achieves timing in this manner. Just my opinion.

 

That is what I made by direct timing....you quoted indirect timing.

It is kinda like saying the volumizer reduces the pedal pressure one must apply to the go pedal....at the same given speed...duh!

If you increase the pressure...more fuel enters the cylinder at the same given duration...to compensate and maintain the SAME required horsepower (same load/speed down the road) the ECM reduces duration. Hence the advanced timing.

It is not direct...and not substantial.

It does not connect to the crank, cam, or data plug...it can't directly control timing whatsoever.

 

I have installed many volumizers on 03's they do plug into both cam and crank...........

That must be a different animal that what I have seen/held. It has been a couple of years...

If that is the case...I may stand corrected.

 

If it is anything like the one I have see....it looks like this:

A 100 hp fuel pressure box with fuel presure sensor and map connection.

Maybe your mistaken?

 

Good call, pressure only.
