Where's the Smoke? -Smarty

[CIverson]

I just got my s-06 smarty and uploaded SW #5. I've heard alot of complaints in the past about excessive smoke, but I barely have any.



I am NOT complaining. It's nice to not blow a cloud. But I am curious what's different. New software?



Other posts I have seen complaints about smoke on level 1 even.



One thing to note is that I have the TNT REVO, and have the rail pressure set to stock, no increase. Is that the reason?

Low/no smoke= complete combustion. You're doing fine! I can smoke up the guy behind me with my Smarty Revo on sw#1. I'm carrying a pretty good load though.

Yes, I realize low smoke is GOOD, and I'm happy for it. This isn't my first trip around the block w/ a performance module, just a different brand.



I am just curious why mine seems so good on smoke and others are complaining.

I'm glad you're having success with the SMARTY. I love the performance gains from my SMARTY, but it still smokes like a fire breathing dragon when set on anything beyond setting 3 regardless of how gently I roll on to the throttle. Right now I am running B99 biodiesel with the SMARTY on 5 and the fuel type seems to have made a significant difference in the reduction of black smoke that comes out the pipe when I get on the go pedal. I have posted complaints about the smoke from the SMARTY setup, but I sure enjoy the power and increased milage (+3mpg when on level 3).

I've noticed the smoke if related to timing. If I run #7 on moderate torque, stock rail, no wastegate, #3 timing (for aftermarket injectors) i get much less smoke (just a tiny initial puff) then I do with #7 set the same except #4 timing (puff + trailing smoke). Both of these are when set on PoD =99.

 

[Regcabguy]

I completely eliminated smoke by resetting the timing to stock,but performance suffers and egts went up sharply. I drove up to 6,000' today with timing set to #2 and smoke is controllable. You just have to take it easy on the go pedal. Settings are: sw#1,tm stock,rp stock,timing #2.

You have an 03. Everybody else thats posted and has smoke has an 04. 5-newer truck. The third injection event certainly is a factor. Take two trucks, the same, except ones on 03-04 and the others an 04. 5+ and put, say, a Smarty on the two. The 04. 5+ will almost always smoke more, and will make more power. Assuming neither is heavily modded...



My 07 will black out an intersection. My 03, however, will BARELY puff a small cloud of smoke when I first romp on it. Anything else is just a slight haze, like my 07 is on the interstate.



It is nice to get in the 03 and have real good power and almost no smoke. The 07 is certainly faster, but also smokes ALOT more!! Especially with the turbo on it

From what i've heard and seen with Smarty if you are not getting smoke on SW3 and up there is something wrong, or settings. (timing)

Now that is an answer I can get behind and believe, as it makes sense. It also stands that most of the 3rd gens out there are 04. 5+, which explains why there are alot more complaints of excess smoke.

I bought my s06 before the revo was available and it SMOKED bad on #5 and up. Now with the new revo update it has made a HUGE differance. The black smoke on hard take off is still there. Found out while turning left to beat oncoming traffic,but it clears up now. It's much more pleasant for the people that I pass on the country roads. After I get passed them I can still see them in my mirrors. The smoke can be fun untill the Black & White with the red and blues on are behind you. Becarefull what you ask for you just might get it.

I kinda wish Marco would release an update that would delay the fueling until boost and rpm's are up a bit. We'd lose some bottom end,but we wouldn't have to be looking out the side view mirror so much. That or get an '03. Maybe the POD accomplishes that.

The newer softwares are better. Mine can still be smokey but with big injectors and slow spooling turbos I expect some. My current REVO TNT program is much better however than the original S-06 software that came with the unit a number of years ago.

There you go> there is something wrong>you have an 03!

As has been said before it is the timing, the year of truck, and I find the Torque Management. I have a 07 and if I keep the TM to 'mild' setting it doesn't smoke much. I only tried upping the pressure once, but didn't seem to affect smoke either way.

What is your Torque Management set to? Anything above the stock (1) setting will cause more smoke, especially at the lower rpms.



Check out the REVO instructions for Smarty Jr... Their level 3 and 4 TQ MGMT are lower than 2 to help prevent excessive smoke.



With Smarty Sr, you are stuck with stock or mild, nothing in between them like on the Jr.



For the record, I have tried SW1 with all default settings, all stock settings, timing and TQ on 2, RP on 1 and am now running with Timing on 3, Torque on 2 and RP on 1 and have had no smoke issues. I get an initial light haze sometimes when I nail it while towing the 5er up a big grade, but it clears up within a second or less.



The PSM CAI and CFM manifold REALLY help with smoke issues...

Here are my observations:



As stated above:

'04. 5 and up smoke much more.



Tq Mang. and Timing play a big factor. I understand the Tq man. but I don't see why timing only increases smoke



Too much smoke is very subjective.



Different trucks act differently. I could really smoke up the world with any (read, timing only) smarty setting before the air flow mods I did. If it didn't improve I was gonna get rid up it.



The single biggest thing related to smoke on the later model trucks is the EPA valve timing. A good cam will make a huge difference. The PDR cam I installed make remarkable reduction in smoke. Oh, I can still make smoke but it's more appropriate now, like if I swat the throttle. Otherwise, it probably smokes like a stock 12 valve now running level 9. A cam is one of the best mods you can do for a late model truck. And it's not too expensive if you can do it yourself.



One thing not talked about a lot is that the smarty changes the fueling curve for that great low end grunt we all love. This seems to be the case even on the "timing only" SW. My theory is that it is fueling a little bit off boost contributing to the smoke. Maybe Bob will comment or it maybe too protected an issue. Seems to me that if this is true, fuel mileage gains could be make with more "gentle" fueling Of course, this would compromise some performance. But they're the experts and I am really happy with my set up now.

You sure that 3 and 4 on Jr are in between Stock and Mild? The way I read it is You have Stock, Mild (less TM than stock), Soft (even less TM than Mild), and Light (th least amount of TM. ) I dont think they are in between Stock and Mild. Progressively less TM, just like Srs. Stock, Mild, Moderate, Wild settings... I was confused by the original post.
