bio fuel ???

bio fuel has less btu's per gallon you need more of it to make the same hp of #2 / its beter lube on all the parts (ip pumps) its a good cleaner (carry spare fuel filters)

think that the product will work just fine with biofuel or even blend style fuel the only thing that it needs is to advance the timing ,hold the injector open longer and turn off the 3rd event on the fueling 05's



I will try one on my 04 and 05 if they would make it (hint hint)

[Mr. C]

But you know what, I was just thingking today about something tailored for the alternative fuel guys. Some file tailored for the biodiesel folks...

We could then have different updates for the Smarty on the web site, Diesel & Alternative fuel ...



I have NO experience with that kinda fuel, can't find it here and honestly won't run it in MY truck. Anyway... what would the Biodiesel need changed in the software ( if any )? More timing? Maybe less? Really dunno will need to look into it.



Marco

Well Marco,

Here is a good source for information on BioDiesel, it is from a marine site but it still should apply here. I copied a bit of it for consumtion here.



Heat of Combustion Properties



Relative to petroleum diesel no. 2, Biodiesel has a slightly lower heat of combustion on account of its oxygen content (petroleum diesel hydrocarbons are not oxygenated). The heat of combustion for soy methyl esters is 128,000 BTU (British Thermal Units) per gallon vs. 130,500 BTU/gal. for petrodiesel. In the Southwest Research Institute study (1996), the heat of combustion for rapeseed biodiesel in blends were compared with petrodiesel. Petrodiesel had 18,400 BTU/lb. , neat biodiesel had 16,200 BTU/lb. (88%) and a 20% blend of rapeseed methyl ester biodiesel had 17,900 BTU/lb. (97%). However, with the added oxygen, the net combustion efficiency for the blended fuel is increased, which should compensate for the slight drop in BTU content. The differences would be most noticed at low rpm and high engine load when the engine would most benefit from more oxygen.



Power Differences



The German study confirmed similar results obtained by Mercedes Benz showing that the maximal torque curve for an engine under load remains essentially unchanged for rapeseed methyl esters relative to pure petrodiesel. Despite the lower volumetric heating value and the consequent lower maximum power output of Biodiesel, the practical results are roughly the same. At a 20% blend, there would probably be no noticeable difference in power output. Good performance in fuel combustion with Biodiesel and its blends resulted in a smooth running engine.



In the Volvo marine diesel engine study in Tennessee (110-HP, 2. 39 L, 4-cylinder, direct injection engine), a tractor dynamometer was used to measure power outputs under selected loads through an engine-mounted reverse drive gear. Exhaust emissions were also tested along with fuel consumption tests under various loads. The conclusions of these tests were that power produced from 100% soy methyl ester Biodiesel was from 2 to 7 percent less than produced from petrodiesel, depending on the load-speed point. However, at or near maximum throttle (3,800 rpm), the two fuels performed the same. Interestingly, at the lowest engine speed (1855 rpm) at full throttle under heavier load, there was a 13% increase in power with Biodiesel as compared to petrodiesel.



I know you are very busy but there could be some room for further tinkering with those of us who are making our own fuel, this would be a good thing to put on the back burner and stir now and then don't you think??



Sorry for taking up so much space, I know there are a lot of people who are not intrested by this but there are a growing number who are.



P. S. my tailpipe smells like french fries :-laf

 

[Bob Wagner]

thank you Mr. C. the ranks for bio are growing every day. thanks for the information link

 

[Marco]

Mr. C

Thanks for the link, interesting read.



Lemme see if I've got it right. Biodiesel, has a higher cetane rating than petrodiesel and it seems to me a little slower burning rate thus the smoother engine @ idle . That would mean it needs higher timing to get the best out of it. Right?

Not a biggie... we can give it a try.



Marco

 

[Mr. C]

Bob I sent you an e-mail, add me to the "list" please

 

[WCounts]

I believe the Smarty is going to work great with the tst on the 3rd gens. I like the idea of the Smarty doing the timing instead of the tst. We can connect the crank and cam sensors back stock and let the tst just do duration. I bet we won't be getting as many 0336 codes and the Smarty can add more timing than the tst could.

Can't wait.

Well took a cruise today to try out the fuel save program. Drove from Flying J in fife to el compradre in castle rock and back to auburn way south chevron



total miles 186. 9 fuel used 9. 297 20. 10 mpg



This is the first time my tuck has ever achieved 20 mpg ever alway best hwy mileage was 19 (remember winter fuel vs. summer fuel)





just wanted to toss this into the mix, Ol blue is running the FS program now too and he logs more miles daily



cheers





added:

road speed varied from 60 -70 mostly closer to 65-67 mph rpm generally 1800-1900 rpm 354 gears dtt auto mach 4's /dodgezilla/smarty



flat level with gently rolling hills, basically I5 between Tacoma and Castle Rock WA

Very promising, Bob! I can hardly wait to get my hands on a Smarty. Oo.

 

[Bob Wagner]

and don't forget more power and better throttle response and drivaability too.



Richard, remember when to say when :-laf sooooooon

 

[smpdodge99]

This might have already been cover before but for those that have a catcher will the smarty provide any additional power or is it just the adjustability, FS, and code reader.

Soon, is good enough for me.

Hi Steve, The smarty program over the older catcher program is very noticable and much more linear.



I was always very happy with my catcher program and marco has made it even better and more choices too.



If you have any other questions please fire away

 

[Murle]

Same here. Went ahead and checked the milage on the stock 2001 club cab one ton two wheel drive. Got one mile to gal. better. Went from 16 to 17 mpg. Also this is the same driving conditions that I do everyday. Hwy and city. . stop and go. The fuel saver mode is more responsive that stock. Not much but some.



Smododge99... The smarty will do everything the CaTHER will do and LESS. By that I mean you now have a choice of the lots of power, mild CaTHER, Fuel saver, Half power... etc. Pluse the code reader. And if Marco comes up with other programs you can download them from his website to the Smarty with you PC.

 

[JHansen]

Hi Marco-looks like you've come up with a winner... I have emailed Bob to get on the preorder list and am anxiously awaiting the magic email saying product is ready to ship! I have 1 question for you-what are the chances of a software upgrade that would let us 2nd gen guys use the cruise control for high idle similar to the 3rd gen trucks? '01 ETH w/servoless cruise here... .



Thanks in advance

Jason

 

[Marco]

I will wait to chime in with my personal experience with the fuel saver software.

First let's hear the results from the other beta testers! Facts, no hype...

I have 1 question for you-what are the chances of a software upgrade that would let us 2nd gen guys use the cruise control for high idle similar to the 3rd gen trucks? '01 ETH w/servoless cruise here... .

As I've said previously in this thread, I'm working on a manual high idle through the Smarty. In other words, you plug in Smarty and set the idle speed where you want it. Anywhere from the stock idle to about 1400-1500 Rpm. As long as Smarty remains plugged in, the idle speed will stay where you have set it. Unplug Smarty, touch the brake or throttle down to stock idle we go.



Actually I have not much time to play with those things, way too much other stuff to work on, but sooner or later it'll come.



I've not yet looked into the CC high idle . At this moment I have no clue if it can be done. I understand that there are a lot of things you guys would like to have, yet I can't do everything right now. We need to start from somewhere and Smarty already offers many more options than others.....

 

[ECappleman]

Can you tell me in a nutshell, what is the main difference of this and one of the other downloaders? Say BD, ect.

It seems to have alot more options.



Also, besides the pedal response, what are the max HP and TQ numbers expected for the 3rd Gen. engines?



I am holding off buying anything else, till I hear more. Sounds very interesting.

The way I see it is the BD only has 2 programs... I think that is right. Also the Smarty can be update on your computer when update are needed or wanted when Marco updates and the BD cannot. Smarty right now in the begining stage has 10 different settings.

 

[Murle]

Ok... Just got the ok from Marco... . For any of you TDR members who would like to try the SMARTY. I'm going to offer to you a chance to try it for a day. All you have to do is come by my shop here in Granbury, Texas. I will download the smarty in your truck on what ever setting you want and let you run it for a day. I will keep the Smarty and you will have to return and I will put your stock program back in your truck. The only thing you have to do in return is to post here on TDR your honest opinion.



Anyone that wants to do this can give me a call at 817-573-9762. I will set a day for you or if you want to just run down the road for a few miles with the Smarty installed that will be fine also. I'm here 9-5:30 M-F and 8-12 Sat.

Wish I was close by, but... However have been tracking Marco for a long time and I will not need a demo. Will buy the Smarty as soon as its offered to me.

 

[Murle]

Yea... I know what you mean... If Marco says it it good then it is good... . Been there done that... .
