Another Smarty thread...I don't like it so far

[Marco]

OPS, I've forgotten to mention. .



I've seen a few mentioning a rattle in cold mornings when the engine is first started. The beta should take care of that one too.

Now that does happen to mine. Is it worth worrying about? Everything else the Smarty does on my truck I like so I'd rather not upgrade to newer softer version if I don't have to.

 

[CumminsBu]

I updated from the 302-202 to the 306-202 and it is much quieter now.

I also notice that the engine is noiser when I put Power Service in the tank. I stopped run that and I do get a knock on take off but I think its an injector that needs to be retorqued because it only knocks when it is hot or its the Power Service.

Oh yea, forgot to mention that to you. With this beta version. My truck is horrible first thing in the morning. Gotta baby it until temps come up. It rattles like crazy with no heat in the motor. Doesn't bother me at all. My truck warms up pretty quick though and want's the temp comes up it's on.

 

[Marco]

With THIS beta update????



C'mon are you kidding me?

Not?

See... I said it, a won battle but no final victoy as of yet.

Back to the softwares... .

I have been pluggin mine in just for that reason.



On a side note, I have had a problem with the ABS Update. I saw it somewhere before and I wanted to say it happened to me. The abs reverted back to 30. 70" when I had been running 33. 55". Not sure why. I will keep an eye on it and report back.

Thanks Bob! I just downloaded the 3e_306_502. zip that Bob sent me for the Smarty and initial test drive is no more timing rattle! Even with the TST set on auto timing and the Smarty set on 9, even though with the 555 engine 9 doesn't do much more that 7. It also seem to react better with the TST! Seem much stronger now and very driveable! I'm going to Boise tomorrow and will get a better feel for it.



Way to go Marco!!

I believe this statement is only true on stock trucks with stock turbos. I see you have an aftermarket turbo so I believe you are seeing the rated horsepower for this SW#. (170 HP)

Marco, I put up a post about this on the product research and development tab.



Is there anyway to get the 2005 model truck without throttle valve cable to have a longer 1 -2 shift? I need my 1st gear to hang on a little longer like up to 17 mph before shifting to 2nd. Right now it does a 1 to 2 to 3 back to 2 thingy before 20 mph which is annoying and I have no throttle valve to adjust.



Thanks, Jason

jason shoot me an email or try software 202b off the site. I have the other updated software if you have timing rattle

 

[CRiggan]

Bob, I shot you an email, thanks, you can also call me tonight at 919 369 1621.



thanks as always ! You strive to help and thats great!

I think I am correct, the 555 engines just don't gain the HP that the 600's do. I think it's something to do with the electronics or injection pump.



Maybe Bob Wagner will chime in here.

 

[AEzzo]

Stock means just that. Stock! Even the air filters were stock...

I've released the information about the HP gains a couple weeks ago and a few of you have complained about the " only 130 hp gain " for the 03 & 04's.

I'd like to point out that the 03 produced 130Hp more @ 30 Psi of boost while the 04. 5 produced 170 hp more @ 40! Psi. Does that tell you something?

BIG BOB you may very well be correct. I only base my assumption on the above quote. It seems to me Marco was saying that the 04. 5 produced more horsepower because it was able to run 10 more Psi of boost.



Bob or Marco care to chime in?

4. 5 and up have bigger injectors stock, it is not just more boost.

I finally got my twins in and went for a drive. With the Smarty still loaded on #4 (beta version). I tried a few other settings along with the TST and never really could get the EGTs to drop or that small hint of rattle to go away. So I put the ECM back to stock and went for another drive. I've always left my TST on 2/2 and my EZ on 2 and never had an issue with temps even with towing. Well with the Smarty out of the mix I know ran about 400* cooler just with twins. Pulls like a mother, no rattle, way less smoke. It's both easier and funner to drive like this (yes, I know funner isn't a word). So I've come to the conclusion of just leaving the Smarty off. I want to thank Marco publically for all he's done trying to get this to work on my truck and taking the time to care. Not to many people/companies are like that, and I want him to know it didn't go unnoticed. Thanks.

The "rattle" appeard to be timing related. I ended up taking some timing away in the low to middle RPM/Load range. For the middle to top end the timing has remained almost unchanged. I mean to say, the EGT reduction provided by the softwares that are in the customers hands thus far should still be there.

Marco-



I finally had time to try out the beta file this morning for about 1/2 hour. Loaded up the #2 Soft Catcher and turned the TST on. I'm happy to say basically no more timing rattle / knock! It just pulls now from right off-idle all the way up the rpm band. Even though the even # softwares are technically supposed to be "no timing" ( :-laf ) you definitely did something to where the timing came in at. If the rattle is still there, it is very slight and essentially the same as when I ran without the Smarty IMHO.



Now I'm happy I don't have to shell out another $300 to get the adjustable timing TST and new remote! (Well,... OK, next month I will ).



Also, it was just at freezing this morning when I drove with the beta program and my truck didn't sound abnormal. I'll be doing some more test driving later this morning and report back. Does altitude have an effect on optimum timing? I'm at 5,500 to 6,500 feet elevation.

 

[CumminsBu]

What is the big problem with Timing rattle? knock, is it the noise or is it damaging the engine? I heard a lot of diesel with knock just off idle that run prefect, Am I missing someting? I'm new to Diesel Hot Rodding but have been working on diesel the last four years.

Well if it sounds like the engine will come apart at the same time it hits an invisible wall while strongly accelerating then I guess I must be missing something...



I'm already running lots of timing advance with the TST and I would think that TST designed it for the optimum or almost the max point (in terms of cylinder pressures versus performance, for example) on our engines. So if Marco can tailor make his software to work with it and the dynamic timing abilities of the ECM without going over the optimum point then all the better. Or am I wrong here?

Is this sound more of a sledge hammer hitting the block vs a small pop inside the engine.

To make a long story short, I will know the sound when I here it.



The most I have done to my truck is the Smarty level SW1 and SW3 most updated version, modified stock air boxs and 4" exhaust.

The way it sounded on my truck was... ... ... . klack klack klack klack klack. Say it loud and as fast as you can, and that is timing rattle. It only did this with the TST turned on.



Bob got me the same program that driverno8 had, and it works great on my truck. The TST and Smarty play nice together again.
