Smarty (VP44) Dyno Test - All Settings

[c-hawk]

Made lots of pulls on a Dynojet 248H today. All pulls were made in 6th gear, and all numbers are uncorrected. Runs were made as close to each other as possible, basically as fast as i could change the smarty program.



The truck was my 01. 5 high output with 118k miles. Performance mods are as follows:

-Smarty

-MITUSA mechanical fuel pump

-MACH 1. 2 injectors

-Southbend 3600 12CB

-5" MBRP exhaust

-BHAF with heat shield



-Program #3 (Fuel, boost fooling and timing) ------------------- 337/802

*(started here because this program was already loaded)



-Stock software (truck defueled because i had no boost fooling)- 234/613



-Program #0 (Half Power)-------------------------------------- 186/456

-Program #1 (Fuel Saver)------------------------------------- 339/810

-Program #2 (Only Fuel and Boost Fooling)--------------------- 324/765



-Program #4 ("Soft" Catcher no timing)----------------------- 330/788

-Program #5 ("Soft" Catcher + Timing)------------------------ 340/812

-Program #6 (Mild Catcher no timing)------------------------- 327/773

-Program #7 (Mild Catcher + Timing)-------------------------- 340/808

-Program #8 (CaTCHER no timing)----------------------------- 325/769

-Program #9 (CaTCHER + Timing)----------------------------- 342/808



-Program #3 (Fuel, boost fooling and timing)-------------------- 339/811

*(went back to first program tested to check consistency)



-Program #3 (Fuel, boost fooling and timing) ------------------- 345/816

*(only change from above run was swaping BHAF for a stage1 AFE intake)

Good post! I always told guys that the sw2 software felt to be the same power as sw8, but alot less smoke. This is why I want to dyno on sw2, 5x4. The additional fuel available from the vp44 should make more power with the drag comp stacked due to the added timing. I can't wait to prove my theory at the next dyno day.

HMMmmm - surprising that the power spread/increase from #2 on up wasn't all that impressive...



I'll be doing a more limited dyno run with my truck this weekend - Smarty/Comp combo - I'll have 3 runs, and figure to run the Comp alone on 5x5, then Smarty on #8 and Comp on 4x5 (some guys claim most power at that setting with the Smarty/Comp combo), and the final run with Smarty on #8 and Comp wide open at 5x5.



Last time I dyno'd, All I had was the comp, and got 311 Hp on a Dynojet. Not real sure whether to run in 5th or 6th gear - I understand it's a Dynojet dyno this time as well...

Gary,



I would run it in 6th.



We tried it in 5th a few times, and got identical HP numbers, but it pulls through the gear so fast it doesn't load the truck as well and TQ numbers are substantially lower.

I've heard the same thing, and am very much leaning towards 6th gear pulls...

I've never heard of guys getting better numbers on 4x5, but 5x4 does give better numbers than 5x5. I am willing to bet sw2, 5x4 will give the best numbers.

Well, for the last several months, on longer trips both empty, and also towing out 5th wheel, I've been running Smarty #2 and the Comp in EZ mode - usually on 1x1. I have all the power (AND economy!) I need, and occasionally bump the Comp up to 3x3 just for grins. Looking at the HP/TQ numbers posted at the beginning of this thread, there's certainly little difference between Smarty #2 and #8...

 

[ThrottleJockey]

c-hawk,



That was pretty cool. I wish I had a dyno I could flog all day like that!

I wonder which program is more economical. #0 or #1?

 

[DMather]

Weird math... I always thought 25 (5x5) was better than 20 (5x4) but maybe the sw2 is a multipiler making the 5x4=40? Or is it custom lumber?

... ... getting better numbers on 4x5, but 5x4 does give better numbers than 5x5. I am willing to bet sw2, 5x4 will give the best numbers.

Seriously, for those of us that might not know what all this is but are interested, it would be nice to provide a reference or not write in "shorthand". I "assume" the 4x5, etc numbers are for another controller? (comp?... what ever that is?)



I've been considering a smarty as my current analyzer will only allow me to read and clear error codes. I've been especially interested in the fuel saver mode and your results make me ask questions.



But, before I get into asking questions that have answers elsewhere... where can I find detailed info about the smarty? Something that tells me about boost fooling, catcher, defueled, timing and what it is actually doing. (you see, defueled, to me, means the fuel tank is empty. ) The marketing propaganda doesn't do anything more than boast, not explain. The dyno results were a step in that direction but need explaining to the uninformed.



I'm currently getting 23. 5 mpg (calculated) and 17 towing and would like to play with engine settings to see if I can squeak more out of a gallon. Efficiency and performance go hand in hand to a point so increasing performance and keeping my foot out of it should have the right result.



Thanks.

HMMmmm - this may seem a bit complicated to explain... . :-laf



The Edge Comp some of us run in addition to the Smarty, has 5 main power settings, all accessible from the driver position control module. In addition, for finer tuning, EACH of those 5 main settings ALSO has 5 sub-level settings - for a total of 25 available settings.



NOW the trickier part - depending on engine setup and other power mods, SOMETIMES the top Comp power settings will provide more fueling than the engine can efficiently burn - and power can actually be less - and EGT's higher than is safe - so turning the Comp BACK to a lower setting - such as main level 4, sublevel 3 (4x3), might actually produce MORE power than main level5, sub level 5 (5x5)



Clear as mud?



THEN, of course, there are Smarty programming levels from 0-9 to further confuse the mix... :-laf

It's always been my understanding that the Smarty setting are all about when the power comes on, not how much. In other words, all settings give about the same power increase, but the higher the setting, the quicker the power comes on. I think this true for all non-wire-tapping power adders (Edge EZ, Van Aken).



That being said - Chris your write up is perfect for me since we have similar vehicles, similarly modified. I have Mach 1. 6 injectors, Airdog, and 4" exhaust, so maybe I get a little more HP. What I find most interesting is the effect of very advanced timing (setting #1) compared to the +fuel settings. Personally, I don't like that setting, gives me a fingernails on chalkboard kind of feeling. #8 is my favorite, but #7 is easier to drive.



THANKS!

Gotta love the SW0:-laf



This is exactly what I expected to see, If you read the Q&A of the VP smarty is says there is no change in peak power, it's all about how it gets there. This confirms that.

ALL of which makes it (Smarty) sorta worthless as a dyno tool, since dyno action involves an instant application of FULL throttle - and little time is actually spent at mid range RPM where the street benefit of the Smarty is most evident...



I guess a comparison dyno graph with/without smarty on the same truck to display any actual improvement in mid range power curve would be the most helpful.

Here ya go,



red = DDII's and banks

blue = above + SMARTY on SW9

 

[Hendricks]

The biggest thing i have seen is the way it will bring a set of big injectors to life. My smarty and my jammers by themselves wherent all that impressive but together they have a huge OMG factor. Ive never been on a dyno but i know what it does on the street. And yes this is about what i would expect to happen since its almost exactly what bob told me when i bought it.

 

[c-hawk]

You all are definitely right on a lot of points, as far as i'm concerned.



The dyno numbers are only measuring peak hp/tq, and as Bob and others have said, power gains are pretty comparable between the similar settings.



The beauty of the smarty, (and i believe Jetpilot says this alot) is in it's driveablility. While peak numbers may be the same, there is a world of difference in the way softwares 3, 5, and 9 drive (for example). It really makes a truck respond well.



The dyno just doesn't show the differences in the way the programs drive.
