How to have a one injection event common rail

That may be but, GM's software isn't proprietary.

Yes, the Smarty " uses " altered code but, it doesn't alter the Dodge software. When you load a Smarty, you're loading software written by Marco, not altered Dodge software :owned:

Same deal with EFI Live you are loading code altered by Ross and Paul. Not GM or Dodge. The Code is till base Hex format just like in a Cummins ECM. If you guys would actually look into you would see things like live swictable tunes, Swicthed outputs, and so on. These are all custom operatoring systems. That is altered code. No different then what a smarty does. For the last time EFI Live does not use GM software. Never has nor will it use Dodge or Cummins software. They redo the operating system to a simpler easier system easier to tune by the end user.

GM software not being proprietary has nothing at all to do with it. Because and I repeat they never use it anyway! :owned:
 
dude... you need to make some calls. You have to have a base line of what the stock software does. Then like EFI, you're able to write code and " manipulate " stock code. The reason EFI can manipulate so many parameter is because the code to the software has been sold for public use.

Why do you think the Smarty is nothing near a EFI ? Because Dodge will not release the codes to the software. Marco is only able to do so much without them.

If Ford and/or GM never sold the rights to their software.... you'd not see a EFI live or people like DPTuners rewriting their codes.

Most of the software is reverse engineered; once you have figured out what parts of the code do what you can alter it any way you want. Smarty is doing the same thing as EFI live, they just do not write a easy to use interface for the end user to allow them to adjust software parameters.

"Dude" you need to get a clue. FWIW I Progam for a living. Not ECMs but CNC machines. I use Mastercam X3 software which is proprietary to Mastercam . But the final code that the proprietary software posts out is .nc. That format can be opened by some other software such as but not limited to Proengineer, Catia, DP Espree, and on and on. The samething can be done with the hex code in the ECM. You do not need "GM" or "Cummins" software to download the hex code from the ECM. Do you really think that only Smarty is using there own software? I now that PPE does not use "GM", "Cummins", or "Ford" software. They are worikng off straight hexidecimal code. Same with EFI Live and most likely many others that make true downloaders.

EFI Live does completely restructure the code. As I already posted look at into DSP2 and DSP5. These are Custom operating systems designed by EFI Live so you can swicth from tune to tune on the fly. Also look into EFI Live speed density. This is a completely new operating system for LSX engines in forced induction applications. GM stuff is set up to work with air flow measured from a MAF. But the MAF is unable to deal with the massive amount of air in a Forced induction engine. So they came up with as system that uses engine rpm and MAP pressure to deal with it. Something never offered by GM. They are not limited to GM stuff because they dont use "GM" software.
 
well by all means johnboy, take up crackin the cummins stuff as a hobby, and when ya get it, retire a rich man....... more power to ya.

As mentioned then.... why don't you make us a EFI for the Cummins if you're such the programmer ?? In fact, why hasn't anyone made EFI for Cummins ?? I know why and have no need to argue with you about it. You obviously need to figure out why.

:hehe::hehe:

I am done argueing with you. That post shows me that you are not capable of understanding.

If you only knew.
 
I understand just find.... just have better thing to do than to argue with someone who thinks they have all the answers. I've made my point and have talked to the right people who do know better.
 
well I know after talking with aem trying to get them to build a standalone for our trucks they say that cant due it due to the fact they cant design anything to control out injector pulses.... im guessing bosch wont realease any software to anyone with pulse control?
 
Please correct me if I'm wrong, but I was under the impression that there are actually parts of the Cummins engine controller that are protected from being overwritten. That would explain why Marco can only "do so much' as he (nor anyone else) has access to the system to be able to overwrite that base system with their own code.

I know of number of a few embedded systems that have protected areas of flash memory that can only be written once. Usually the manufacturer places their core proprietary code here and places data tables and or patch code in the updateable areas. This keeps their core code (and in some cases hardware) "safe" from competitors yet gives them the flexibility to tune the system.
When you are dealing with a black box of this nature you options are very limited. Replace the controller with one of your own design or purchase the core code from the manufacturer so you can flash your own.

My take from reading the EFI site is the controllers (ok ECM.PCM, etc) they deal with don't have these types of limitations as it looks like the can completely overwrite the the units with their own code.
 
There was a guy on CF that cracked the ECM on a 2nd gen truck with some software off the internet and was using another software to upload new code and was actually reading all of the tables and what not. So if a guy in his spare time can hack the Cummins ECM and see all of the tables and change anything he wanted to then why can't a company like EFI live or someone else do it?
