Where do you get a tool to read the CM2200 ECM? Would that tool allow you to write files or reprogram the ECM?

In light of all the recent EPA business I assume all of us are going to have to become experts on writing ECM code...but where do we start?

I can read/write tunes for CAT ECM's but the connector isn't the same...or is it???

That may be a million dollar question...

U assume wrong. No reason doing something when its being done for u. Nothing has changed to this point. Except for availability of product. That will be remedied at the end of the month.

I'm not giving anyone my VIN, name, address, and or pictures of my vehicle to get an unlock code for "high sulfer." I'm also not risking registrating a "race vehicle" which according to the EPA is a 37K dollar plus fine on top of taking all the DPF stuff off.

This is less about the EPA and more about the 2010+ club not really having a lot to work with despite coming on three years. I know the H&S guys are very busy right along with EFI live, but both of them are really restricted as to what they can give us at this point.

I want more.

I'm gonna call a few places I've found already that claim to be able to take an ECM and create a program from it that allows you to see every parameter in there and control it...God only knows how much that's gonna cost but I would like to have that kind of control.

I'm not going to spell it out for you, so let us know how the expensive method goes.

No need to "spell anything out" I've got a pretty good hold on legality and cheating systems. I'm not going to argue semantics with you either...but as of now, it doesn't look like "nothing's changed."

Who's talking about cheating and legality??? I'm saying not to take certain things at face value and that looks are decieving. Its one of those read between the lines type of deals. Your assuming I'm talking about something else. And since I no longer will talk about anything that might help us in open forum. I can't tell you what you are missing. But I can garauntee your missing.

No worries. I'm interested to see if you can come up with an entirely new programming system. Something only a couple of companies world wide have been able to do and spent millions doing it.

The wheel is still there. Don't need to reinvent it. Just gotta figure out how to use it a different way. :thumbsup:

Back on topic, what do you need to communicate with an ECM? I realize that the information that comes from it will then need to be decoded, re-coded, have to be able to run a checksum etc. but I've never done it through an ODB-II port before.

It's super easy. That's why everybody is doing it these days.

Start with a pin out. The ecm only uses a couple of wires for communications.. positive, negative, and a couple extra's.. Your going to have to get it on the bench in order to work with it. Certain programers won't allow bench tuning.. Best bet is to modify an existing one to work with what you want. H&S doesn't like to flash on the bench..

That's the next thing you'll need to figure out. What modules do you want to communicate with. There's more than one.

Please explain?

It's not rocket science ace...I did it every day on Delphi ECM's for CAT before becoming a lawyer. Granted I had millions of dollars of equipment to work with but it's still just information.

 

[Drake_Lawdawg]

I've never done anything through an ODB-II port...all been on a bench with straight connection to the ECM. if these were just Cummins ECM's I assume we could just hook up straight to them but I can only assume there are a million points between the ECM and the ODB-II port that have to be satisfied as well.

Is the CAN bus J1939? If so, I can use some old programs and a simple ODB-II port to USB to GET the info...right?

I don't know what's needed between the ecm and obd. But yes. There are certain things that are depending on the software your going to use. And honestly, I haven't looked at the pin out in a long time to remember. I would have to dig it out... Its easier to order a plug by the way. So you don't have connectors so close to other pin's. But its do-able without the plug.

I can look later this evening if you haven't found it by then.

I will just get a Galleto (or whatever they are) ODB-II to USB...my concern is the checksum phase. I am not sure if the computer will do that part or if there has to be something in between the two. Seems like there was something (obviously a ton of things) between the dock station and the ECM that functioned as the flash tool b/c the docking station wouldn't do it...I can't remeber either it's been a few years since I sat at a spaghetti code desk station.
