Engine/Transmission (1998.5 - 2002) EFI live for the Cummins?

[FTwardoch]

So it doesn't appear to be available for the Cummins guys... ... ... ..... any idea why? It seems a better alternative to 'touchy ' electronic adders as I believe it controls lockup and fueling, etc is fully programmable with a laptop.



Any thoughts?

I'd like to know too

van aken will have a new chip out soon to do this sometime this month. from what i heard it will be great. i am getting one as soon as they do and will be getting ride of two boxes.

It's not available for Dodge because EFI Live was made for Chevy gas engines. i. e. Corvette. I don't think that the basic ECM software is all that different between any gas chevy and the D-Max so it wasn't a big jump to do the diesel. I have to assume that the ECM for the Dodge Cummins is totall different from any other Chrysler product due to the fact that Cummins is not an "in house" engine for Chrysler like the D-Max is for chevy. (don't tell me that the D-Max is isuzu because it isn't available for any other vehicle except a chevy which IMO makes it a chevy) For EFI live to jump into a whole new business they're not familar with would be like John Force trying to race at INDY, they both have 4 round tires but that's where the similarities end. I would assume that if Dodge was a viable market that was easy to do I would think they would have already done it.

What is EFI ? I only know it as "electronic fuel injection" as on gas engines.

Sometime all of these abbreviations go right over my head.

Maybe we should do the full spelling the first time up, ( for "not so smart" people like me) then use abreviations for further discussion.

Thanks for any feedback on this.

EFILive is computer software that is used to tune a chevy ECM. And by "tune" I mean completely write your own fuel curve and transmission shift points. You can blow an engine up with the wrong click, it's not like a downloader.

It say isuzu right on the engine id tag making it an isuzu made for cheby just like power stroke is made for ford and cummins is made for dodge. :-laf

You are correct but as I said it's only available in a GM product in this country so IMO it's a GM engine. Also it's at the the GM plant in Moraine OH. So unlike the powerstroke which is also available as the IH444 and the VT365 in international trucks and busses, or Cummins ISB which can be had in any number of trucks, the duramax is a chevy product only. (available only in other countries in the Isuzu trucks. )



The HEUI injection system on the 7. 3 Powerstroke was made by Caterpillar but it's not a Cat 7. 3 powerstroke.

If you compare a d-max to an isuzu engine, you can see a lot of similarities between the two. Supposedly it was a joint design between isuzu and chevy... neither of which I care for very much

 

[BTighe]

i thought GM owned isuzu.

EFI does stand for Electronic Fuel Injection, which our trucks do not have till you get to the 3rd gens. The only way to add power is by changing the pump timing and fueling, you can't change injector firing control like you can with an EFI engine. You can adjust the curve as the Smarty does, bringing it on lower. You should be able to adjust the shift points and control lock-up as well.



There was a thread a few years back about an engineer from Cummins that reprogramed somebody's ecm with a laptop.

I know 3 guys that run EFILive around central ohio and it is an amazing thing and it is so cheap to operate. But you really have to know what your doing to build a good tune. Lots of test and tune but it is amazing what that system can offer. You can literally change any parameter in fuel, timing and so much else with a click of the mouse. You can also data log everything that is happening to the truck as you make a run, like rail psi, timing, rpms, the size of the fuel shot. One of them dynoed his truck at 544 horse and the only thing else he has is a fass fuel system and an air filter with a built transmission.

I heard there are Cummins guys running it with 2 cylinders "shut off". Lots of wiring involved I'm sure, but it seems possible, given that D-maxs and CR 5. 9s run basically the same injection system.

I don't see how that would be even remotely possiable since EFI live is just a program made to work with the GM ECM, which is nothing like the Dodge/Cummins ECM. It would be like using a Smarty on a Honda Civic. Unless someone has figured out how to hack a GM ECM to run a Cummins (which I highly doubt). EFI Live is realitively new for the D-Max, (used for years to tune gassers) so to assume someone in that short amount of time was smarter than the guys at EFI Live and managed to do somthing they didn't do with the product they made seems unlikely.

All it takes is one good hacker!

 

[DCreed]

the question should be, "if they did, where can i get one?!!"
