Engine/Transmission (1998.5 - 2002) caTCHER ecm (Marco's aka MAD)

[Murle]

Darkhorse, Changing the ECM is no problem, I know from experience

 

[smittybuilt]

marco, i think my ecm should be on the way too. i have an 02 six speed. is there problems with the flashing of the 02's like the 01's?

 

[John - K5AWO]

Dang, I've been a winner twice and did not even know it. Oo. Oo.

I think that clinches it Murle..... :-laf

 

[Turbo Tim 1]

So after Murle found out his 2001 truck has a 2000 program in it I decided to try out the year 2000 Torques Maximus ECM in my truck since mine was built in June of 2000 also. So I swap out the ECM's reconnect everything and turn the key, Wait To Start comes on and everything looks fine so I fire her up, idle is extremely erratic for about 5-10 seconds the it settles right out and purrs but at the same time the tach stops working. Knowing that without the tach the cruise won't work I change the ECM's back out, so I'm guessing I've got a 2001 program.



Now I also got to thinking about the issue with the cruise, my truck is a 2001 with a five speed and from what I've read it should have electronic cruise control, but one time when I was working on the truck I knocked the hose off of the vacuum pump and the cruise wouldn't work, I put it back on and it worked fine, does that mean I have a vacuum operated cruise or do they all use the vacuum in some way? Having the cruise operational is important for me since I do alot of highway driving, I want to try out the CaTCHer but I want to be sure it'll work the way I need it to. I already have the spare ECM now I just have to come up with the scratch to have it programmed.

I would have figured by now ole Marco wouldnt have any hair left... :-laf :-laf.



Thanks for answering my questions Marco, as soon as the funds are availiable... . sounds like the next modification for me.



I would like to know though, what is it you are trying to find out by scanning? Before I send out the spare ECM, what information is it I need to find out for you... Marco... . that is necessary for you to program the ECM. And how do I find out the information you need?



Would I lose the Cruise Control on my 2002, and have you had any trouble with the 2002 models, like you have had with the 00, 01, 01. 5 models?





Damn, there I go again with more questions.....





Thanks

Any ideas, Marco ?

 

[Marco]

Sure, Sorry... .

And how do I find out the information you need?



The information I need is the "software version" number. That's the number written into the ECM's when they're flashed @ the factory or later then by a dealer. That number can be read with any DRBIII aka a dealer. That number is unique for a given SW and identifies the truck without any possible doubt.



Would I lose the Cruise Control on my 2002,



NO! Not if your truck is really a 2002... that means if you're 100% sure that your truck IS a 2002 then I don't even need that SW number because the 2002 are not as complicated as the previous two years.



and have you had any trouble with the 2002 models, like you have had with the 00, 01, 01. 5 models?



No not yet. For the 2002 there are only automatic, 5 speed, 6 speed and obviously Epa or Carb. So if you tell me that you have let's say an 2002 six speed ( HO ) Epa... NO PROBLEM.



Helps?

[Marco]

TT,



Murle's truck is not an 2000 it's an 2000. 5!!



That eratic idle and dead tach mean without doubt that your engine does not have the Crank sensor. The MY 2000 had crank and cam sensors, the 01's only the cam. Thus the erratic idle you get.



BUT, is your truck an 2000. 5 or is it an 2001 or is it an 2001. 5?????

That's the question. Most likely it's not an 2001. 5 but then there are still two different SW's. Only one of them will work correctly in your truck.



Which one do we try first?

It's a 50-50 thing... :-{}



I think the electronic CC came very late in some 2001. 5's and then in all 2002's. ( Is that correct???)



Marco



P. S. on edit. The crank and cam sensors have been in use up to MY 2000.

From MY 2000. 5 only the cam sensor has been used then.

 

[Marco]

smittybuilt,



From what I know today... .

No the 2002's are not as difficult as the 00-00. 5-01-01. 5's.

For the 2002's there should ne no problem.



BTW I've seen a lot of 02's for the story of the emissions here. They were all the same files... .

All of the information above is available from Cummins Quickserve on line. Would this information be helpful?????

 

[Marco]

tractorface,

Thanks for your interest!

No that's not what we need.

That looks like the information for the whole engine as it comes from Cummins. The ECM is an DC part. .



The number we need looks something like 333033305j or 323730306j...



What I find almost incredible is that even the DC system does NOT know what software version was written into the ECM ( What engine version is in the truck ). From what I know the only way is to hook up the DRBIII and read that number. Maybe I'm wrong...



Someone over there has an buddy @ a dealership over there. Maybe you could find out more? I've talked with our local Chrysler dealer ( a buddy of mine) we found nuthin...



Any help is WELCOME!



Thanks

Marco, I have a stupid question for you ..... am I correct in saying that you need to know the software version of the ECM that came with the truck I own now.



For clarification purpose, the spare ECM that I have ( supposedly a 2000 model year ECM ) and will get reprogrammed, you dont need to know the software version of it, because you just need to know what version of software to put in it... ..... correct?



So I can get the (ECM) one currently in my truck scanned for the proper software version via a DRBIII..... let you know what that version is and then you reprogram my spare that i send you..... no matter what year of ECM I have? ( 98. 5 - 2002 )



Thanks for your time and patience... .

marco - my truck has a build date of 08-2000, yet i have the 4 wheel abs/disc brakes and electronic cruise. When i swapped out my 6 speed for a auto, the donor truck (build date of 9-2000) had the 4 wheel abs/disc brakes but vaccuum controlled cruise. Could i have kept my original ecm and electronic crusie?



ps - how long does it take you to turn around the ecm's? Doug was going to try to get me my ecm before my show this weekend because we are dragging and i have horrible defuel issues. Im thinking that might not be abe to happen though. Have you gotten his package yet?



Thanks!!

I have a 2002 that has a vacuum CC. I have heard that the 2002 auto's have vacuum CC's. I know mine does.

Marco, I have a friend that works in a dealership and he has access to most everything. Just tell me what you are looking for or what you need.

 

[John - K5AWO]

Software Version # Required.... Yes

Marco, I have a stupid question for you ..... am I correct in saying that you need to know the software version of the ECM that came with the truck I own now.

Git r done.



Yes, Marco MUST have the exact software version number from your ECM (in the truck). You must have access to a DRBIII scanner to retrieve the number.



Either a dealer or a good shop or buy one.

 

[Marco]

GIT-R-DONE,



Like I've said in my previous MSG, IF your truck is a 2002 then I don't need the software version number. If in doubt well then it's better to have it read with a DRBIII. Yes any ECM into any truck. Who cares what SW was in it. The SW I write into it is what counts.



SilverDodge,



Recived the package by 5 Pm my time. I've started to test drive the ECM's in my truck. I think I will ship them back Friday afternoon or Monday. depends upon how many problems I'll find with the ECM's this time.



About the CC. ALL automatic trucks have the vaccum activated CC. That's because the OBSOLETE transmission we've got from DC regulates the pressures through the cable. The later stick trucks have the electronic ( ECM controlled ) CC. They don't need the movement of the go peddle for pressure regulation. I don't know exactly when they started to use the electronic CC...



Bob, what we'd need is to find a way to identify the software needed for a given truck without the need to read it with the DRBIII. I find it incredible that a DC dealer can't find the correct software for a given vehicle through the VIN #. Somehow, somewhere in the MDS system there must be a way to find the software with the VIN...

Do they always first hook up the DRBIII , read the SW# and then download the correct SW to the DRB? If I was DC I would request the VIN, decode it, find the matching SW based upon the VIN, download to the DRB which downloads then to the vehicle... Isn't that less difficult?

Who ever said DC did things the easy way??

 

[Murle]

This may sound dumb, Marco, but If you are testing all of these ECM's in your truck to see if they work..... Then why won't any ECM work in any model of truck?? I mean why won't the 2001. 5 ECM software work in a 2001 and visa versa? I'm sure you do not own every model of truck out there. Clear as mud???

 

[Marco]

Murle,

My truck is a '99.

Testing them does not mean that they work as supposed. Obviuos that all 2000. 5 an later ECM's will run in limp mode in my truck. Nonetheless, I see if the Throttle / Oil pressure/ wait to start etc etc work. In other words I test to see if they have hardware problems.



Anyone can do that with any ECM in any truck... .



Clear as mud?



Marco

 

[Murle]

Got ya, I knew there was answer. Kind of like my truck with the wrong SW. Somethings worked and somethings did not.
