EFI live for Cummins

[JasonCzerak]

Jason... BSFC does not work that way. BSFC to be put into simpler terms is the amount of fuel required to drive an engine to produce HP. The math does not lie, it requires that for a given HP we have a given amount of fuel required to produce that hp. So a 160 hp engine requires x amount of fuel to burn( remember these are peak hp we discuss here to keep it simple). A 325 hp engine reqires Y fuel to burn. Both these engines @ lets say 1900 rpm require to different amounts of fuel to burn to keep running since the 325 hp more is making more hp @ 1900 than the 160 @ 1900(I do not have power bands for these engines in front of me at this time). Yeah. . we could factor injectors, timing, turbos... ect but thats too many variables. Lets also remember we are talking about two different types of injection(mechanical vs electronic) one fixed and one infinatly variable.



And yes weight and gearing has a lot to do with it but these new engines are so much more efficent than the older engines.

I see you point in regards to X and Y fuel rates to make 100hp at 1900rpm and they would be different because of the differnet injection styles.



But the other point here that the CR's have less MPG is mostly due to the truck behign heavier and in 4x4 case, more drive train resistance. .



Assuming the CR's really are more efficient and that they are, but they ahve to over come so much more to give the cusomer what they want (or think they want).



I just wish people would figure this out already and stop beating the dead horse



Well, my 12 valver got 29mpg and this and that and my CR gets crap for MPG



Yeah, but could your stock 12 vavler pull the same load up that same hill faster, cooler, quiter, with the A/C on while you have your DVD playing for the kids in the back seat of a mega cab as a CR? prolly not.

i will be getting a new file next week, should give me about 30% more fueling than the program i have now, from 2500-3500rpm---thats going to be nice, after i get the new vb in, and valve springs, and tires i will be able to get the track info and dyno info you guys want to see... ... ... ..... Oo.

New file??? I thought you said you had a custom tuning program like EFILive?? So is your "Custom programing" more like the SCT or Smarty?

i elaborated on that in the first few posts, the beta on this box is to establish the high and low boundres for a auto tune, so you dont have to blow you truck up in the process of making it faster, you can start at the auto tune and work from there, instead of adding full timing pressure and duration from the start and them blowing you truck, also the monitor enables you to infinatly adjust the settings. we have not got that far yet, like i said it is like the EFI only it does it on the fly, or will at least. hope i did'ent confuse you.

Can't agree with you more on this... I love the new engines and I wish people would stop complaining. Yes the 12v are VERY good and reliable engines but people tend to forget how hard it was to get 600 hp from there 12v and how much eaisier it is to get the same from a cr motor. Slap on a few boxes, sticks, turbo, studs and you have a hell of a machine. Yep... CR motors are still in there infancy but give them a few more years and we will see where the 12v will be, another steping stone in cummins history along with the p-pump... LOL hehehe.

ok i just got word that they are doing the EFI live thing in stages, the first 2 will be on box program tuning only, then the other two will be with a live monitor that will allow the most from your truck, it will save low and high points recall all engine opperating parameters and with the upgrade package + 300hp you will sign your truck away. . ( liability) and then you can blow you truck up with ease or make an additional 500hp, depending on how you tune it. there is a lot to this thing so let me get more into the testing and we will talk later. i think i will make a new thread for this too. :-laf

I hope it all works out. Especially the RPM limiting. Knowing who is behind it makes me think that it should be a good product. Now if they just bring it to market soon.

you know your right i forgot all about them, i have just had so much to do lately. i'll see if i can get some pictures

 

[Diesel Power]

on the head, i should have some pics saturday.

 

[smokinrod]

thank you much

 

[WShupe]

HMMM, I guess everyone else is misinformed. But then again we loved the two ECM's we had so much that we gave them away. And aslo because your customer service is so great when someone asks about changing back to a stock ECM.

shoot me the details or fill in the blanks

nobody is disputing that the smarty isnt a good piece of hardware. the fact is, if some builds a program like EFI for the cummins, pretty much every programmer, downloader & box out there will be a piece of outdated machinery. just look what its done for the duramax. the serious HP junkies dont want pre-packed , sugar coated... ... stuff. we want to be able to manipulate the raw data, re-do our fuel curves, adjust every degree of timing, etc.



deep down i think this scares alot of the established box/tuner community. granted, there will still be a certain percentage of consumers that want to be led by the hand, but im betting that people will be unloading their "pre-programed hardware" like crazy. right from day one i never wanted some "magical box", i wanted to know exactly what it was doing to my engine & how i could fine tune it to my needs.



EFI, or whatever name this goes by..... i cant wait

 

[BSwope]

My buddy has the EFI live in his Duramax and its alot of work and NOT adjustable on the fly..... i hope that if this one comes to be for the cummins its not as much work and hassle as the one for the d-max!

 

[MCummings]

I've done HP tuners, and it's alot of work too, but, the more work you can do, the more you can adjust, and modify.



Both HP Tuners, and EFI Live have "preprogrammed" files that you can start with, just download them, and try them out... . then go from there... .

and thats the best part--on the fly

 

[Bob Wagner]

on the fly is smoke and mirrors and nothing more
