Engine/Transmission (1998.5 - 2002) ECM uprate at cummins

[Morphious]

Does anyone have any information on whether cummins has a higher ecm upgrade for the dodge? I know it's questionable whether or not cummins can flash the truck's ecm, but I believe I remember reading where someone was able to get it flashed. While my trucks at Cummins getting diagnosed, wanted to see about getting it uprated as well on the 'puter side if possible.

I could be wrong,but as far as i know the only uprate for the 24V's is for the 98. 5- to present 5 sped trucks,it costs about 1000 bucks,and gives only 10hp,but brings the torque to 505,similair to the HO 6 speed trucks have from the factory. it voids the warranty on the rest of the truck,too,only the engine warranty remains. If it were me,i wouldnt even ask them about it,go buy an Edge EZ,it will give you 2X the power gain of the uprate,you wont have to remove your ECM,takes under 5 minutes to install,and can be plucked off in under 2 minutes if warranty requires it to be. Oh yeah it cost 1/2 what the uprate does,and includes a boost module for raising boost,and future mods,like injectors.

I've got an EZ and DDIII's on the truck already, and have 165k miles on the truck, warranty I'm worried about NOT. I'm just seeing if there really is something out there I can get done while it's at cummin's, if not, no biggie.

Morph, ask Howard next time you catch him on chat-I think one time he mentioned he had a Torqus Maximus ECM. Don't quote me though-I have been known to be wrong before-last time in 1993 I think

I've been wondering...

I realize that the ECMs on non-Dodge ISBs have lots of features built into them that we don't get with the Dodge ECM. If one was to upgrade to the Torqus Maximus, which is supposed to be a Cummins ECM, would this potentially provide us with those features that the other non-Dodge ECMs have? It seems like the Dodge ECM is a single 50 pin plug and the non-Dodge ISB ECM is a dual 50 pin plug??? If this is right, is the Torqus Maximus also a dual 50 pin ECM? I realize that the wiring might not be in place to support these features, but i'm guessing that someone on this Board could figure out how to make it all work if the capability existed in the ECM.



just thinking out loud...

The Torque Maximus is a dodge product and not worth the money. The true cummins ecm is a dual 50 pin module.

Thought I remember a long time ago reading Cummins could re-flash the ECM, or maybe it was Cummins could do it but would not becasue of EPA issues.



Wasn't there some talk saying a true Cummins ECN would not work in our trucks becasue it could not communicate with the Dodge PCM? Besides like mentioned earlier the wire harness is not set-up to handle for the extra 50 pin plug so how would you tap into the added features even if the Cummins 100 pin ECM was compatible with the Dodge PCM?



Hopefully someone more knowledgable on matters will chime in and clear things up or shead a little more light on whether Cummins can re-flash the Dodge ECM for power upgrades and if the Cummins 100 pin ECM is capable of working in our trucks.

The ECM "CAN" be reflashed with a higher power Cummins program but I HIGHLY doubt you will find anyone willing to do so. Cummins payed MAJOR fines to the EPA for reflashing ECM's a while back. TST was sued by Cummins for reflashing ECM's with a higher power Cummins program based on copyright issues.

Don't confuse the Dodge ECM with a Cummins ECM. The one on our truck has only the manufacturer in common, Motorola. Other than that Dodge puts all the software on this this, not Cummins. Not to say Cummins cannot read it or update it but they don't know whats loaded on it at the factory. The uprate ECM is a Dodge product sold by Dodge and Cummins but strictly Dodge.



The other issue Cummins has is that with only 50 pins how much memory does this thing have compared to theirs. How much can be loaded on there and if it was would it work anyway. Motorola makes this ECM to Dodges specs not Cummins and only has the pathways/memory in it to run Dodges requirements.

you know it's really too bad that they don't allow someone who owns their truck, to modify it however they want, i. e. TST.



Maybe one day Marco could finsh teasing us, and release that MAD ECM for a fair price. #ad

Morph, shoot me a PM or an email.

Pcarlson:



You are somewhat correct in your statements, but some are not correct.



"they (Cummins) dont know whats loaded on it at the factory"



I would beg to differ on that one, Cummins developes their engine to Dodges wants and needs, that includes writing the software to run the CUMMINS engine.



The ECM on the Cummins ISB for Dodge is a Cummins part 50 pin

The Dual 50 pin ECM is also a Cummins Part (both are manufactured by a supplier).

When I had my truck at Cummins there was one that Cummins could not even read. It was either the PCM or the ECM... . can't remember which, but they don't have any ability to change things on the Dodge end.

 

[pcarlson]

Justin,



That info, correct or incorrect came from Cummins. Motorola supplies the ECM to the specs requested 50 pin vs 100 pin. Cummins told me they do not load the software, Dodge does so Cummins would not know what was loaded and what wasn't. Cummins only supplies the part per the contract from their supplier, which happens to make the Dodge ecm and the real Cummins ecm.



The 94-02 Dodges used Cummins software but Cummins didn't load it from what he told me and that the new 03's use strickly Dodge software on the ECM.



Cummins told me they supply the engine, wiring harness, ecm and Dodge is responsible for the rest. I. E. , software, warranty, replacement parts, etc. , Cummins is not contracted to do anything else.

Like Steve has said, it can be done. Cummins will give every excuse in the book as to why it can't be done so that they do not have to say it can be done. Cummins can read, and change info in the ECM, but not the PCM. That is the way I have always understood it, and I have done a little research.



Patrick,

I believe that you recieved this info from Cummins, but Justin works for Cummins also.
