I'd expect that the Smarty is getting all the fuel the ECM can deliver, so wouldn't the current ECM with a Smarty obviate the need for an SO ECM?
If not, how come?

I would have thought so too, but it seems no. We all know the difference in the 2 pumps with plunger size and pressure. Well, the HO ECM sends a shorter electrical signal to the pump as it will flow just a hair more fuel in the same time. I am talking milaseconds here. So when you put an SO pump on with the HO ECM, the pump isn't seeing the longer signal it normaly would with the SO ECM. I tried running an SO ECM for a few days and my truck does fuel harder. I was seeing about 4-5psi more boost with no other changes than the ECM.

I can see that if you have an SO pump with an HO ECM you might not get the full benefit if you are using a timing type module or Smarty or something like that.
I do not see how a wire tap module cannot supply as much fuel as you desire? The ECM has nothing to do with it once you take control over it. If you are on the pump wire you can go to 10x max fuel stretch at idle if you feel like it.

You are actually talking more like microseconds.

That is a tuning issue. Not a limitation of the pump.
The only limitation of the pump is how much fuel it can physically move which is limited by the plunger.
What de-fueling issue are you having?
Maybe in the long run there needs to be different tunes for the HO and SO pumps in order to get every last little drop of power from them? I think the HO would require slightly more duration for the same amount of fuel?

with everything in my sig I will either defuel at 2700rpm with smarty off or on setting 3 and about 3100rpm with smarty on setting 9. I can run the TST on 0-9 and it will still defuel and when I say defuel I mean the engine flat falls on it's face.

Qzilla If I jumped an extra 5 volts to the map + to your box at idle will it start fueling ??? or does it need a signal to map - , I tried this with a TST and i got no responce

Holy moly. This is a very nasty box. Every bit as strong as a TST/Smarty stack. And I'm running the smarty on stock right now. It's so nasty in fact that with my fire hose injectors I can't cruise above level 1 because it starts to shutter the pump but as long as I keep accelerating it doesn't shutter. It also doesn't shutter when you back out of the throttle like the TST does. It's very heavy fueling. The bottom end is absolutely incredible. Massive amounts of low end. And the top end is every bit as much as the TST/Smarty. I can't wait to get this cruising issue worked out and really see what this box is like. EGT's on the higher levels rise slower than the TST/Smarty and boost is actually up about 4 psi over the TST/Smarty. I'm hitting 52psi and my gate is set at 48psi. With the TST/Smarty I hit 52psi but fall back to 48psi. Not with this box. It holds 52psi. I may have just found a new box for me to run.

Right now I'm running smarty stock and Quad on 2 and it's every bit as strong on the bottom end. Feels like the smarty on 5. This box is very very strong. Tomorrow I'll give it some more testing but for now all I can say is WOW.
