Smarty, the new CaTCHER tool.

[Sixpack]

My is the same way. It is supposed to clear when you set it back to "stock" setting. Let the code scoll all the way through and you will see what I'm talking about.

I got my Smarty. Had to download #9 just to see what this thing would do on my stock truck. All I could do was grin and smile. I could not believe that my truck could accelerate that fast. Boost comes up alot quicker, EGT running a bit cooler than stock, and the truck flat out moves. Installed the boost elbow and I can get a max boost of ~28psi. I've been running around with #7. Its fun to get a puff of smoke if get on the throttle. I am going to run #7 until my next fill-up and then probably run the fuel saver for a while. Any suggetions on what program to run when pulling my 30' stock trailer. Loads can get quiet heavy and I still have stock sticks and clutch for now. Thanks Bob and Marco. Now I'll sit down and enjoy my candy bar.

Software Unknown

Anyone else get a "Software Unknown" command from their Smarty? I just got a chance to download mine today and that's all I got once I tried to download the new programing.



Thanks

DB

:{ Yeah,I got the same thing. Returned it to Bob for an update. Turns out I've got a 98. 5. Date of birth: 8-98. Also had trouble getting it to even come on. Would work then not work. I'm going to break out the dielectric grease upon receipt. I had removed the Edge :{ and then had to put it back on.

Just an update on fuel mileage on fun Factor 8 19. 02 Miles per gallon, since im in Maine its gota be a winter blend. #8 has given me an increase of 2mpg.

 

[flattracker]

Received my smarty yesterday removed VA and installed #9, power about the same as the VA just compressed 80% of throttle in to the first 20% of peddle movement, didn't care for the irratic throttle personally and put a very irritating surge in my cruise.

Worked my way down the numbers till I got to 3 same power just much more linear throttle and much smoother than my VA which also had an occasional stumble under full boost the Smarty seems to have eliminated.

Then set Smarty on 2 and stacked the Va with it,major smiles whole lot of fun factor would estimate in the 300 to 325 hp to the ground range , a lot of fun but would need more turbo to trailer with it without burning down, currently still running 35hy with wastegate set at 28lbs.

Without additional timing, what besides driving style do you think caused the extra MPG? SNOKING

I have no idea what caused the additional mileage. The overhead is recording 22 mpg on #8 I had no mileag savings with program 1.

I'd be interested to see what it comes out as when you hand-figure it. The ECM could be throwing your overhead way off - I know the EZ will do that. The overheads are notoriously inaccurate anyway. Any chance you could hand figure it to compare?

 

[ThrottleJockey]

ThrottleJockey - Thanks for chiming in on the timing discussion. Your opinion agrees with my sentiments about advanced timing. Without a way to measure cylinder pressure under load conditions, I can only say that advanced timing just doesn't feel right, more responsive throttle yes, but the engine just doesn't sound good. In Hohn's defense, he has spoken out against timing advance, especially for the HO motors, more often than not. I interpreted his comment differently. That is, the HO motor is designed for higher compression, including a differently timed VP44, than the SO motor, therefore better able to handle more timing advance than the SO. However, advancing timing much more than stock on an HO motor is riskier.



I felt this way when I ran an Edge EZ, same when I went to the Comp, and the same, if not more so, running any odd-numbered SMARTY programs. The huge advantage with SMARTY is that you can run the even-numbered, non-timing programs. I really like these programs better, even though the throttle response isn't as sharp. I've tried program #9 twice and quit it after one run, both times. Even though having big low-end power is fun, I can't use it without making big clouds of smoke. Smoke is bad advertising for diesels, so I prefer not to make it. Now I'm in the process of experimenting to find the most usable setting for my tastes. One setting for daily driving and probably another (lower setting) for towing. I only tow occasionally, but in the 17-18 K gross range.



As for the fuel-saver program, which seems to have the most timing advance of all the programs, I think this would be good for longer highway trips, empty, when you are driving in an economical style (low load, low boost, low temps).

Neil

Neil, I hear you, but the VP-44 does not have static timing, the ECM varies timing in accordance with input from various sensors on the 24 valve engine. The pump has nothing to do with it. It's all the ECM (hence the fun Marco has bestowed upon us all. )

The HO engine cannot endure more peak cylinder pressure than the SO can. The HO engine CREATES more pressure with it's higher CR. The block, head, headgasket and head bolts are the same on both engines.

Kent Crowders puller has a CR of around 10 to 1. It takes two cans of starting fluid and an engine oil heater to start the thing. Why? So he can cram 170 psi of oxygen rich boost into the 360 cubic inches. Kent knows he has a limit on cylinder pressure. So he lowered the CR to gain boost.

19 mpg was hand figured, on level 8. 17. 3 hand figured on level 1 EGts are 100 deg cooler on 8 I enjoyed an article this week in tdr 51 about egt's stating 600 is the ultimate for fuel. Level 1 has my egt's just over 600 level 8 is 510 or so. As stated earlier I have a 410 re HO truck. Im throwin the #s out there so members can see what its doin.

 

[CHornsby]

Got mine today plus a 100 grand candybar????????



Put program 9 in and then turned on the TST to Level 9. Smoked out the entire road AND lost traction in 4th gear.



Too much fun to calculate mileage yet. I'll do that some other time!

 

[flattracker]

The candy bar was a nice touch bob knows the way to a fat mans heart. LOL

 

[DonS]

Mine came today, as well (along with the unexpected treat).



Straight to #9, and fixed my tire height. It's like a new truck.



Now I'm waiting for Bob to send me my Mach 4s...

 

[turbo torque]

Still checkin the mail box for mine. Talked to Bob Wag. the other day.



Guess there's a little problem with the 98. 5 - 99 5 speed's.



Should be updated and here soon. hope! hope!



PS: Just got my frantz oil filter today

Trying to understand this, so what you are saying is that the HO motor doesn't need any extra timing? So that would mean using all of the even numbers. Or does Marco take into consideration with the many programs that are in the Smarty, not to add too much timing to an HO motor?

The 98. 5 update should be completed this weekend. My intrent is 100% customer satisfaction bar none.

I can tell you from personal experience that my '01 HO ran very nicely with the odd numbered programs. #9 is my hands down favorite.

Yes it does run great there :-laf Had a test drive from Bob with a unit at a BOMB party.

If you stack the Smarty on level #8 with an EZ, how many horsepower can one gain from this combination? I know the point of the Smarty is to improve driveability, not huge power gains. I already have a DDTTPM and am on the list for a Smarty. Will this be a good combo or am I better off ditching the box and running the Smarty alone? I eventually plan to go with 1. 6 EDMs but haven't got around to it. I hope my number is up soon so I experience the gains you all talk about.
