Too Smoky !!!!!!!!!

[Tinman]

I looked at that link and your right, it is kinda complicated. Not like the olds days of static mech. timing. This is what has me wondering. There is no way to say this without sounding disrespectful (which is not my intent) but how much does the aftermarket know about what they are doing with the these newer engines? If you just change the timing curve, other things may be adversely effected that could harm the engine; cylinder temps/pressure spikes, high smoke leading to sooted oil, etc. How are we to know? I know a lot of their info is proprietary but it's be nice for someone to step and tell us what they are doing and why. They wouldn't have to give specifics but generalities. Bob and Marco's reputation preceeds them and it is well deserved, but I wonder what information they us to determine the Smarty's software.

Unfortunately it is more complicated than just basic timing when dealing with multiple injection events per power stroke. Here is the link I posted in another REVO thread that sheds some light on this: http://www.tytlabs.co.jp/english/rev...3_009hotta.pdf



It details how the timing of the pilot injection event needs to change in relationship to the timing of the main injection event based on engine load. If you read nothing else, at least read the “Abstract” paragraph on the first page of the PDF document, it will be better than my trying to paraphrase it accurately.

brods...



Can you check that link you published please. Can't get it to work... went to their site but can't figure out your link.



Thanks,

Peter

REVO software download this weekend! I'll post back in a couple of days with my luck. Anyone who has suggestions for settings to try please post them. Engine is stock. -see my sig.

Oops. Fixed it so it should work now.

Revo observations.

Mine has the 4. 14 default program running. Smoke is minimal as long as I don't bog it,which is detrimental to the engine and drivetrain anyway. I jacked up the rp to #1,but that only got me worse fuel economy and no reduction in smoke. Due to constant load and stock clutch I only run sw#1.

2x what Tinman said.

 

[osiris]

the settings i have been running are timing on 4 everything else set to default

 

[Tinman]

What is the difference in the REVO and TNT software? Is is more than fueling and RPMs?? If it smokes less, there must be other differences

 

[osiris]

I believe the TNT software starts out at 100 HP and goes up to 230 HP and it is for highly upgraded engines while the REVO is good for relatively stock engines...

 

[Paddy McMahon]

New revo software installed and still too smoky! even on setting one I get black smoke on the slightest throttle at highway speed. I am back to Edge juice on setting three with no smoke unless I mash the go pedal. definately not as responsive as SMARTY, but no motorists flying the bird to me when they follow me up a grade or from a stoplight. I'll keep the SMARTY for OBD purposes and just use the scan features.

This may sound odd, but I have found that running sw#3, #3 timing, #2 torque was more smokey from 0-10 PSI of boost (rolling throttle, not just nailing it) then sw#9, #3 timing, #3 torque. Both had factory rail pressure. with #9 loaded if I roll into it accelerates "easier" with no smoke until I nail it. Nailing it from low boost (2 psi or so) will smoke, but nailing once it gets to 10 PSI and it clears pretty fast. It will be nice when the kinks are worked out of the lower settings since its kinda tough to tow on 9!

 

[Paddy McMahon]

I'll try your settings just for grins and see what happens. I love the throttle response of the SMARTY and I am pretty gentle on the go pedal.

 

[Tinman]

I wish Bob would chime in a confirm they are working on this. If there won't be any progress on this smoke issue, I'll just get something else for power. I need the timing for mileage, but it's just too smokey.

tinman...........

i think i mentioned it to you before, i absolutely recommend the PPE. it is a really good piece. mileage and power with very little smoke, i mean, almost stock smoke... ... ... . i am stacking it and gaining great mpg and power. still have a setting up to go... ... need to message my transmission first.

 

[Tinman]

Yeah, I looked at the PPE website. I like what you are saying. But I have concerns about any other downloaders. I'm confident Smarty won't make permantent changes to the ecm. Marco really works hard to make sure every different software is covered. I've read of other programers (not necessarily PPE) don't return all the correct info to the correct address files making permanent changes (unless you get a dodge reflash). Plus the PPE doesn't have the adjust ablility of the Smarty, but I'm not gonna tolerate the smoke, so I may give PPE a try.

 

[Regcabguy]

It seems the reason for the smoke is the low rpm,low boost fueling Smarty provides. Most other power providers hold off until boost is up. If Marco keeps lowering the smoke quotient,we may just end up with middle and high rpm fueling that most other power boxes,programers etc. now provide. Low end fueling plus insufficient air supply=smoke. I'm pretty satisfied with my Revo settings,but due to the stock clutch, I'm way down on SW#1.

 

[Tinman]

I agree that the smarty fuels low, but I can run the timing only program and get a lot of smoke, no extra fuel. I can run the 130 hp program with no timing and get no smoke until about 75-80% throttle. Appears to be the timing to me. I,for one, would be glad to give up the low end fuel for no smoke.

 

[Bob Wagner]

I can't say much at this time but more changes for the better are just around the corner.



Please be patient and you will be very happy.



Thanks for your continued supports, MADS Electronics is going strong

I'm not convinced it is due to the timing. If I leave the timing on 3 and go from SW #1 to SW #9 I get much less smoke on a light take-off with #9 then #1. It also seems to rev-up easier (and with no smoke) on #9. Now if I punch it then all bets are off. I'm just saying that if the timing is really the same between the two then there is something else at play. If I could get the 0-10 psi boost (easy pedal) smoke from #9 and put it on #1 with the less touch throttle of #1 it would make towing a bit nicer... And might make a few people behind me happier too

 

[Tinman]

Thanks Bob, that's what I needed to know. I'll wait and see what you guys come up with.



One thing I've noticed on the forums is that different trucks seem to have different smoke with the smarty. Certainly the '04. 5 and up trucks will smoke more than the '03-'04 truck b/o the valve timing (something I'm planning on fixing). But it may be sw too. I can't imaging the headache Marco has to deal with all the different ecm sw in these trucks.



The after market definitely has to deal with the smoke b/o I'm afraid it maybe only be a matter of time before the whole country is like Commifornia and anyone can call up and report smoking/polluting vehicles. Plus all that smoke is unburned $4/gal fuel.
