I hope this question doesn't sound too silly, but in the absence of official, from the manufacturer full settings descriptions, I'm wondering what the SW# level settings are for. In the original Smarty, the higher settings basically brought the fueling in earlier in the RPM/accelerator stroke. All CaTCHER settings delivered the same total HP gain, just on milder to wilder curves. It seems to me that is what the Torque setting does now. If that's true, what does the SW# do? Is it a percentage of additional fueling, e. g. HP gain from 0-65? To be honest, I haven't tried SW1 on Torque 6. Guess what I'm doing on the drive home :)



At least it's fun to play with the truck again!



I wonder the same thing. To my thinking the "Catcher SW" must be a different animal. Or is it all just smoke and mirrors... ... :confused:

I'm starting to think that the SW settings are "metering" the amount of extra fuel that the fuel injection pump delivers.

Much to my surprise, my favorite setting so far is:
SW1, Torque 6, Timing 3, Duration 1.
I find this to be very snappy off the line but doesn't hit as hard or smoke as much as the same parameters on higher SW numbers. Roll-on power on the highway leaves something to be desired, but in stop-and-go traffic, it's fun with little drawback.

Also curious, I turned the Duration to 6 and the roll-on power was even worse. I still don't get Duration or maybe it was just a bad combination with my Mach 1. 6 injectors.

I find it hard to believe that parameter changes can be affected on the fly without reprogramming. I don't know how this stuff works and haven't be willing to try it. Y'all go first ;)
 
The smarty is not designed to be adjustable on the fly. If you do so you are doing it at your own risk.



come on now, did we ever say adjust on the fly? :confused:
 
Nop, your correct sir, but can we just make an adjustment change only to example:sw7 or do you have to make an adjustment then reload the entire sw7 ???????????????

Yesterday I tried: SW3 TM6 T2 D4



I ussually run with the TST on 4, this I found out is a possible bad move with the TM set so high. I am glad I was not in any traffic, because I am sure I would have rear ended someone the first time I started out and half way got on it in 2nd gear. After testing what the heck just happened, I found out that the boost builds so fast that the TST fires at its 5 psi boost threshold and fires pretty darn hard. Basically 2000-2200 rpm and then the thing jumps out from under me.



The first episode scared the "pee waddin" out of me and like I said I am glad I was not in any kind of a traffic area. Never done that before, no matter how hard I pushed on the diesel peddle.



This is an unstable tune for the street, at least for me... . :eek:

Towing,



What are your thoughts of:



SW3, TQ2, T2, D2



A little more TQ to get the load (13k) moving, No too much T because of the weight of the load, A tad of D and base that on how the EGT's are running (if EGT's are low (less than 1000*) add a bit more D: 1 unit at a time (until you get to 1000*)



I would think adding D also holds the fuel solenoid open longer and may at some point heat the VP44 frame to unacceptable levels (unless you are running really cool fuel through it & an OAT blower). That fuel solenoid is a HIGH amperage solenoid (ie generates a LOT of heat).



ENTIRELY new concept, very cool

Bob Weis[/QUOTE]



Just a point of clarification, Bob. When the high pressure solenoid is activated it holds the valve CLOSED which delivers fuel to the injectors. When power is shut off, the valve opens & the pressure collapses ending the injection. Minor point but I got that out of the Bosh Diesel Engine Management book. All the fueling boxes that tap the wire extent the activation of that solenoid & therefore are creating heat in it's coil. I would question how much of that heat gets transferred to the pump body as it is outside the body surrounded by the high pressure outlets to the injectors.
 
I had a thought on the duration setting. Those of us that run a Blue Chip FMS, FMSP, Or Redline have a setting (Set from BC) that can be altered to specific VP pumps due to solonoid variations that also control duration when the box is fueling.



Can the smarty AND the FMS compound duration OR is it the higher one wins kind of situation.



I noticed that in "Drag Mode" I am seeing a less aggressive "Lazy" fueling thing and was wondering if hat may have something to do with it?





Hmm maybee I am going back to stock duration on the smarty ?
 
Someone please try sw3 2,1,2... let me know how it works. . no other boxes, just Smarty. I tried that yesterday and the truck would not shift until 2200rpm, no matter where the throttle was at??? Just wondering if it is my truck. Switched back to sw4 3,1,3 and it was normal again??

Currently, I think SW3 TM4 T2 D4 is my favorite so far.



When running unloaded this brings boost more slowly so that the TST can transistion to its fueling ramp more controllable. With TM set higher it causes the TST to go off like an young lad during his first turn in the sack.



I turn off the TST to tow and I have not towed anything yet.

Ran mine yesterday set at SW3 TQ6 TM3 D0. Loved they way it ran. With the TST on ran SW3 TQ6 TM0 D0.

I have my TST set on 4 ussually, becuase I like the power it provides in the 2000-2500 range. With TQ set at 6 my truck becomes unstable in 2nd and 3rd gears. On the higher TQ settings it builds boost so fast the TST fuels hard and the darn thing takes off on me big time. Not used to that.



With duration set at 4 the Smarty SW and the TST start fueling around the same time. Which seems to be around 2000 rpm. Then away I go!:-laf

Bob,



Were you ever going to answer the question on "default settings"? An answer or a no "I cannot find the values", would be nice. Still seems ridiculous to have default settings with no values.
 
settings

Well I have run sw#3 tq6 t-2 d 2-3. tst on 4this setting is touchie but it is actually decent to drive in town with. it seems to spool quick top end is less powerful I dont have a cam or twins yet. noseeum. your cam and twins which I wish I had i wonder if this is why it hits so hard for you. with my TSTpm3 when it kicks in its not that hard on sw3 I feel it kick more on sw9 for me. today I drove all day on sw 9 tq6 t-2 d-3 and tst on 6 it lays the smoke but if I feather into the power it was very controlled but like others have said on sw3. on sw9 this gave me a hard kick with boost very quick around 2200rpms I hit 35-40lbs easy the top end comes alive for me. my bottom end has always suffered alittle due to going with 35 inch tires but not on the top end.

Im wondering know if I do go with a cam if that would help bring the power in earlier around 1800-2000. thanks for the replies good to hear updates.

I tried SW4 Q3 T2 D5 yesterday. throttle response is toned way down. I would call it basically stock plus.



Odd for sure, before running SW3 I had been running SW7 with the same options. Seems to me, that for some reason, SW3 runs much harder.



Any time I have selected Q6 I build boost extremely fast.
