I have been running SW3 Torque4 and Timing4, truck is powerful off the line but it seems horsepower is down. I went back to SW3 default/default and it was a total pig. So i know that sw3 tq2 tm4 was also a pig, now I am running sw3 tq4 tm default...seems to run pretty good! You would think that the timing adjustment would change the responsive throttle not the torque??? What does Smarty Jr. do to control torque management? Does it back the electronic throttle off if it senses tire spin?

 

I have been following this thread and I thought I would let you know what my findings have been. I have had the JR since it had the original software and then I downloaded the 5.08 software and now I have the 5.09 software. I have found that the 5.08 seems to run the best on my truck with SW levels 2 and 3 but 5.09 seems smoother and stronger bottom end on SW level 1. On my truck 5.08 had a very drastic difference with TQ3 and 4 being much stronger than 2 but 5.09 doesn't feel much different on any of the TQ settings, from TQ2 to TQ4 the truck feels the same. My truck seems to need alot more throttle to get moving with the 5.09. I think that I am going to go back to 5.08 since I mostly drive on SW2 and 5.08 felt better to me and then I have the option to change the TQ settings if I want snappier throttle response since the change was very noticable on the 5.08.

 

I've only had my JR for a couple weeks now, and less than a year on my truck, but I've been reading until my eyes feel like they will fall out. I've gone back through many of the threads since the JR came out, and it seems there has been much confusion since its inception. It seems most of the old threads about the beta's are no longer valid. However, there has been talk of 5.07, then this one references 5.08/5.09. Now 5.10 is out which is what I had available to download. Most threads have a lot of people's personal experiments and informed, educated deductions. But many of them seem to end with someone saying, "hopefully Marco or Bob will chime in and confirm" this or that. Then they seem to die without that authoritative voice. It would be nice to see this thread stay active until we can get that official verdict on the TM and TQ settings of the newest software.

On a side note, I'm still trying to wrap my mind around how to get the best mileage out of my truck. I drive like a grandpa, and my commute is short ~7 miles. The truck is just at normal operating temp when I get to the parking garage. Mixed city driving and a weekend or two pulling a 6,000 pound travel trailer to the lake I get hand calculated 16mpg before Smarty. Upon much of my reading and my own pre-conceived notions, I initially tried SW #1, TM4, TQ2 POD 50. I don't have gauges or a built tranny, so I was a little concerned running higher. I haven't finished a full tank, so I have been relying on the OHC to give me a clue. It has always been about 2 higher than hand calculated. I may be making an incorrect assumption that it will remain the same 2 mpg high, but that's what I'm going with for now.
I then saw several posts from Bob indicating the best mileage would come from SW#3, default/default if you could control the skinny pedal. I tried it, and it seems to be working, but I'm confused to as why. It takes fuel to make that kind of power. I was thinking the lower power settings with the POD way low would give the best around town since it would have the least amount of power, and should logically use less fuel. Naturally the most timing on either setting should help with economy.
I did however try a WOT on #3 just for fun to see what this thing would do, and HOLY COW! I made sure I wasn't doing anything crazy like a boosted launch. I was just rolling down an on-ramp about 20 and mashed the skinny pedal and the backend broke loose. Don't mean to hi-jack the thread, just excited to finally have my diesel, and Smarty JR.

 

Welcome flatlander, be sure to fill out your signature. The reason they recommend the SW3 is due to the amount of "duration" that it adds. Every truck is a bit different but I got my best mileage with SW2, TQ2, TM4, POD 80. Just how I drive. If you are going to use switch 3 I would choose a lower TQ number and number 4 for the timing to get better mileage. Then dial back on the POD till you like the dislike the driveability. If you do alot of in town driving the reduction in TQ and POD will make the most difference I think in mileage.

 

Well from what I can confirm from my truck is that higher levels indeed gain better mileage. I believe this is for the reason that though there is more potential fuel being added, you do not have to use as much throttle to propel the truck. If you are a sensible driver, you will benefit from this. Of course this matches the other benefit of more timing and more duration, which will also help bring egts down.

Do us a favor flat lander and fill in your sig so we all know what you drive and current mods. This will help us help you quicker.

 

Guess I got the cart before the horse. I had filled in my user CP, but must have started the reply in another tab first.

 

No problem man. It happens. Welcome to the site BTW.

 

I'll try it on TM4, TQ4 and see if it changes much. I'm pretty restrained and can control throttle input without limiting POD. With POD decreased, ie lowering from 99, does it actually fuel less? For instance, at idle, with POD set to 50, does it significantly use less fuel than at idle on 99?

I will take a 1200 mile trip at Thanksgiving, so I will get to try a couple different settings eventually with notable results, but for now I'm stuck in town to and from work.

 

Well I went to change sw setting and got an mess. that communication was lost return to stock. Also happened to a bud of mine as well a while back. Anyways after returning it back to stock and then going back to my normal sw3 tm4 tq4(which tq4 was most agressive) Well lets just say not no more. Tq2 is now wicked touchy just like it use to be and tq4 is just enough like I remember.
So with that said I was talking to my bud and he said his did the same but thought it was in his head so did think anything of it.
So I'm woundering if it was because we updated the Jr to 5.09 with out returning the trucks to stock first?? So when the error happened the update didn't take hold till it went back to stock and then back to Smarty software?
Just wanted to share.

 

Not sure on the update part. Just to be safe, I set it back to stock when I updated to 5.10. I'll definitely agree that TQ4 is much less than TQ2. When I first set it to TQ4, I thought I still had the POD dialed down a bit. Seems 4 keeps that extra power in check pretty well early on.

 

So I see some people are using the Smarty Jr for mileage but how about for power? Im getting the feeling that I should have just saved a bit longer and went with the Sr. I know quite a few people are satisfied with their Sr's and it appears that they are pretty straight forward as far as the power levels and settings......why cant the Jr be that way? Seriously, I have tried almost all the combinations that my Jr offers (its not POD) and none of the combinations make sense. Obviously SW3 will produce the most power to the ground right? I try combinations that others recommend and my truck runs like a fat bastard. I just want to know from Bob or Marco what the best "power to the ground" combination is for a fairly stock truck. Currently running SW3 tq4/tm default.

 

Well Crude dude if you have it cranked all the way up and still want more I'd sell it and get the Sr. I see you have some gauges and transmission parts so it wont kill that. Once you get the Sr. you might think about a lift pump if you use the higher numbers. The Jr. is mainly for people like me with 0 tranny mods thus far and the Jr is quite a bit cheaper (~$300 less new).

I dyno'd at 387hp/707ft/lbs with the smarty jr only. More than enough for me, but ill upgrade once my truck can handle pappa smarty.

 

I can handle the power no problem. I could've gotten the Sr. but chose the Jr. because I can run my VA box with it. If I need more power I flip the switch and add 70hp. If I need more I flip it up one more notch and add 130hp. It plays VERY well with Smarty. Actually the VA runs well with pretty much anything. It's a shame they went out of business.

 

I guess it depends on which version of the software you are running. I have mine on TQ4, and it seems to limit it the most. However, I'm running the latest 5.10 version. It must be different for the version of software you are running.

 

FLAT, on torque 4 is the throttle quite a bit more responsive? When I adjust mine it seems that the TQ is the only one that makes a difference. I would think that timing would make the throttle response better. I get either very sluggish off the line power with very little smoke sw3 tm default and tq default, very responsive with no upper rpm power and tons of smoke sw3 tm4 tq4, and ok throttle response with ok higher rpm power and a little smoke with sw3 tm default and tq4. Smoke doesnt bother me, just adding that info.
