Smarty, the new CaTCHER tool.

TST does NOT add timing.



Trent

 

[Mundgyver]

The TST adds fuel though correct?? Could it be that maybe the combination of the Smarty adding fuel and timing along with the TST adding fuel that maybe you are seeing a defueling situation?? Speculation on my part here Maybe that is why the HP dropped



Food for thought.

 

[MCummings]

There is a point where you can only ask for so much fuel from the '44.

[Bob Wagner]

agreed and the smarty is all about drivability

 

[DThelen]

I'll see what kinda milage the truck gets this weekend, my wife just went for a 300 mile trip and it had a 100 mile's on it aready. I have the fuel saver program.



Dan

She got 19. 5mpg driving 70+. It is the best it's ever done on that trip. But I have done 19. 5 before, ussually have to drive about 60mph to get that. It seems like we get 18. 5 on the runin the past. then Fan is off of it right now too. That's the first time thats been off. Could be my 1 mile to gallon increase. She also said it Accelerated a little slower but held the speed better than with the EZ on.

made 514HP with smarty on number 7 and no other boxes on. and made 537HP no smarty and tst on #7.

Heavy Hauler,

You want me to shed some light on this one.

HOW could I possibly do so? I don't know anything about the truck and the mods and have never seen it.



Something does not sound right though. Smarty alone did ONLY 23 Hp less than the TST on #7!?



Now, as much as I would like it, NO WAY Smarty could even come close to beat a TST box top HP/Power wise! 514HP with Smarty and no wire tap per se is a very good result. The combination of Smarty & TST did not as expected...



Possible reasons for THAT truck? Not enough fuel? Not enough air? Too much backpressure? Too much fuel thus not enough air? Tired VP?

How could I possibly determine what's the reason?



Did the smoke ever clear up during that run? You know there's that new kid in town, Smarty. I've already seen several times situations where too much fuel was the "problem" with my toy. More air... . See the trend?



Simply adding Smarty into an existing scenario might not be enough. I mean, if you add big sticks to an otherwise stock engine you already know that you'll need more of a turbo, more exhaust, better air filter... Add Smarty to them sticks too and you need even more of all the above if you want a dyno queen.



Helps?

 

[DarrellB]

I do have a queston for any one that can answer it.



When does the high idle function on Smarty kick in? I only had my Smarty on for about 3 days before I had to tear my truck down so I haven't had a chance to really play around with it much so I thought I'd ask. Right now it's kill'n me leaving it on level 2 till I get my fresh rebuild broke in.

that truck has a HR44 but they were saying it ran out of air ,, he also has a redline box too 3 in all hehe u can see the vid of the truck here http://video.thedieselgarage.com/video/456CB901-CF15-4D19-80D6-23EFDFD0BF1A.htm red/silver

 

[Dieselnutz]

The red truck is the one in question. Mine is the silver one. I am very,very pleased with the driveability and the results! Oo. I think the VP44 was just out of fuel! We are talking about Double the factory HP/TQ ratings here. Will anyone ever come up with a computer controlled stupid pump to replace the VP? Thanks again Marco, and thanks for the video.

 

[HeavyHauler]

Marco - I didn't mean to step on your toes. You should know as well as anyone how much I love my Smarty by my lengthy review on this thread. All I hoped to gain out of posting that was to find out whether those results were normal (Smarty w/TST). I just didn't want to run out and drop $600 on a TST box if I wasn't really going to gain anything by it. If that's the way it is, then that's fine - I'm satisfied with what the Smarty does for me. But apparently those are not normal results, so that's good to hear. I figured the truck in question didn't have enough air, but I wanted your take on it.



I was wondering if the Smarty and TST box somehow cancelled each other out to an extent. It does not sound like that is true either though.



Can anyone out there speculate as to what type of gains one could expect when stacking a TST box with the Smarty? Assuming plenty of air and no other problems...

ABSOLUTELY!



I had enough air with my stock HX-35, until I added the Smarty - then I "lost" the higher settings on the Comp, not enough air, too much smoke and EGT - but not just because of the Comp, the Smarty ALONE on #8 will billow lots of smoke.



NOT an issue about the Smarty, just clear indication of need for more air, if I want additional benefit with my particular setup. But I don't want, or need more performance than I now have, so will gladly use what I have and turn down the Comp and Smarty to keep the engine happy with the stock turbo.

Here's the scoop on the high idle criteria... .



-----------------------------------------------

Once enabled, idle speed will slowly ramp up from 800 rpm to 1200 rpm when all of the following conditions are met:



1. Intake Manifold Temperature less than 0°C (32°F) and,

2. Coolant Temp is less than 60°C (140°F) and,

3. The Transmission is in Neutral or Park and,

4. The Service Brake pedal is not depressed and,

5. Throttle = 0% and,

6. Vehicle Speed = 0 mph



Additionally, if Intake Manifold Temperature (IMT) is less than -9°C (15°F), and all of the parameters above are met, three of the cylinders will be shut off upon reaching 1200 rpm, creating a slight change in engine sound which is normal. This allows the engine to create increased heat in the cooling system, allowing more rapid engine warm up and cab heating.



Both features will automatically disable when one of the following occurs:



1. The Automatic Transmission is placed in gear (forward or reverse) or,

2. The Service Brake pedal is depressed or,

3. Throttle position is greater than 0% or,

4. Vehicle Speed is greater than 0 mph or,

5. Coolant Temperature is greater than 79°C (175°F).



Engine speed will return to normal operation at 800 rpm. If the engine continues to idle and coolant temperature is at or below 60°C (140°'F), the feature will reenable. In order to operate properly, the Accelerator Pedal Position Sensor (APPS) must stay at idle.



NOTE: ANY TYPE OF AFTERMARKET IDLE SPEED KICKER THAT ACTIVATES THE APPS WILL DISABLE THIS FEATURE.



Use of the 110V block heater will not allow the feature to function after an overnight soak. If the vehicle is left idling, without use of the block heater, 1200 rpm operation will begin when the intake temperature drops below O°C (32°F) and coolant is less than 60°C (140°F).



I know it works, because after trying a Smarty earlier this year, I had high idle the next morning when the temp was around 19 out. Didn't get cold enough to try the 3 cyl idle though.

 

[David_VT]

BOB, it arrived ... way cool!! and thanks again for the other part, that one will end up on the 99 as it is much nicer than what I have. The spare engine will get the 99's!



RE: HIGH IDLE (on my 99 5spd)

I've used the high idle since the dealer finally figured out how to load it. I find it wonderful for my environment (Northern VT). I never worry about the truck getting cold when running at idle for long times.



I work 2nd shift and usually start the truck as I fill out my log book at work. I usually smile when I hear the idle kick up after it is running for a short time. I know it is cold when I hear the clatter/hum of the 3 cyl idle kick in.



It is interesting that the smoke/vapor trail from high idle all but drops to zero when the 3 cyl idle kicks in.



I can confirm that when running at idle in the cold, like at an accident scene with my warning lights on, that the high idle will indeed cycle back in when the engine needs warmth.

Get a vp44 from scheid

Thanks guys!



It's warming up here in Indiana so I dought I'll be using it anymore for awhile but I was wondering how it work.

HH,

didn't want to sound upset!

In fact, I'm not.

So this doesn't work with the manual transmission?

 

[BSmalley]

Bob & Marco

Just got my Smarty this morning. Didn't even make it out of the parking lot at the post office before I had it installed. All I can say is. . :--) Oo. Oh my God, some stole my truck and replaced it with this one... . Absolutely incredible... . To anyone sitting on the fence about this... ORDER ONE TODAY!! You guys have done an incredible job. Thank you for all the hard work and the plenty of sleepless nights that I'm sure were involved. AWESOME.

Thanks

Bill

It works with the manual transmission. As long as you have the parking brake on and your foot off the service brakes.

 

[dslmacdown]

So this doesn't work with the manual transmission?

Yes, it does. It works in my truck just fine.
