I think they are moving away from Bosch and going to a Delphi system. ;)

Ill attach a picture of why I think this is in a couple minutes.

Im sticking to this educated guess...if im wrong you guys can all :p: at me because I was wrong, and if im right, I can :p: at you guys because I thought of it/made the observation before anyone else did. :D

ben

In for the pic:D

ben it has been more than a couple minutes wheres that pic

pics yet?

Why dosent delphi make a common rail for the duramax? Don't they have one for smaller engines? Im sure it has something to do with money?

ok here is the first picture, ill add more supporting pics in a minute

Holy crap all that new emissions stuff makes me shudder....

thanks for the pics ben your knowledge overwhelms me. :D

So much for GM engines having room to work with now. God damn...

Ben, sometimes i think you have too much time on your hands... :D

remember back when 4.5 was coming out. the 4.5 and 6.6(thought to be 6.9 displacement increase) would share same ecm with ability to control individual peak cylinder pressure to reduce NOx. so they probably been working on this during bosch ecm use.

So Ben, is this going to be a good thing or a bad thing then???

Should still be a lot more space the PSD or Cummins. The radiators on those trucks are pushed right up to the front grille.

Ben- thanks for the pics and observations.

Looks like a cluster Censored

Hell yeah, just look at the flippin + battery terminal, 6 damn wires coming from it...one looks like it wasnt from the factory however.

What year model is the urea tank going to be introduced?

"But the LML won’t use urea alone to lower NOx. Our sources say the LML will also add a second exhaust gas recirculation cooler to the engine, similar to the dual-EGR cooler setup that the 6.4-liter Power Stroke diesel uses."

Its still pre-production, chances are they are being used for monitoring and testing devices.

man...........u got alot of free time bro!

Like asked before is this gonna be good or bad? is Delphi better then Bosch??

Ross (efilive) says the ECM's are a lot nicer to work with and easier to tune.

Does this mean no more DPF?

I think its DPF+Urea.

As far as emissions go, I could care less as long as they dont rob mpg or get so hot that they will ignite a wheat stuble field.

DPF is still there...here to stay it is.

epa, even if component or device is not needed will not allow it to be removed, just modified. so expect cat, dpf and urea maybe the only thing that can be dropped, maybe. glad that ecm will be easier to work with.

I doubt that the 2011 LML will be a Delphi, although we will be pleased to be proven wrong. Ross would be VERY pleased and relieved indeed!

At this stage the rumour we've heard is that the 2010 will be another Bosch ECM, but different to the LBZ/LMM controller, which is bad news given development will have to start from scratch. If that rumour is true hopefully it's not a traditional Bosch European ECM which is un-hackable (ie BMW).

The Delphi Diesel ECM in one of the earlier pic's is currently available as an aftermarket controller - they are not currently used in production vehicles.

Ditto, we can't even consider getting a new diesel because then we couldn't drive it into the stubble or CRP.

Both my 08's are driven in wheat or oat stubble, no issue here... Never say never but I think its a none issue. The fact that every new Diesel has one would soon prove there was a problem. Not everyone will skip the new truck, even if they drive in dry grass, the same thing was said when cat's first came out....

What's your average rainfall there? I'm just really leery because we only get 9-11 in of precip a year. We've had catted gas rigs start fires before (trespassing hunters, can't say it was the cat for sure though that started it). Not trying to argue, just curious if it still might work for us.

Now back on topic :D.

Right and my uncle was a witness to a cat starting a fire in a field.

Also what happens down the line when the DPF gets a lil older and possibly gets a hole in it?

I can drive 45 minutes from one section to another, if a regen event occurred will the dpf be cool enough when it is a 100+ out and everything is dry.

Remember the ford flamethrower lol

i worked for delphi/gm and was finally let go...alas no where to go anymore with the losses, but i can't say i could not see it coming... My GM/Delco...and later Delphi Energy and Engineering plant closed down 10 years ago....and I was left wondering how to feed my family when they decided to move my job to Mexico for people that were willing to work for .89 cents and hour when I made 14.24 + 1.90 shift premium for working 3rd shift

Thank god for the UAW and Unions in general...I went to school and became a Diesel tech and went to work at a Freightliner Dealership as a Technician... Now I run the entire shop for 25% of the week in a 24 hour shop as a Service Manager.

anyway... i dont care nothing for Delphi anymore...and I really don't give a rats ass for GM...(or should i say OBAMA..who let GM dump my PSP retirement and savings program)


what i want to know....HOW MANY AMERICANS are gonna be employed or is this another mexican venture?...or what?

So if I understand this correctly, there is a chance that EFILive will not work with the new motors. I could see GM doing this as a way to limit people from adding chips/programmers and then trying to do warranty claims from damages caused by these programmers.

I hear the "light" rain fall, but if it was that big of an issue the fire DPT's and such would be starting them, they update equipment at taxpayer $$ every few years.... Anything that can happen will, our friend Murphy is always ready to cause issues :rolleyes:

It all depends. European and Japanese car makers have pretty much NEVER allowed access to the ECM. Look at the tuning programs available for Mazda and Toyota - they simply don't exist. My Mazda diesel has the ECM fitted under the floor of the front passanger floor pan, it's contained in a welded box, so we couldn't even get a glimpse of it.

Some of the European manufacturers, such as BMW use Bosch for their ECM's which are unprogrammable. Not even the dealer can reflash some of them. Infact, the ECM some of these vehicles use is VERY similar to the LBZ/LMM ECM - just with different options and access levels. In this instance, GM has 'requested' to have access to the ECM for dealer reflashes.

It is feesable that at some point of time GM may prevent access to the ECM - I can't answer if they will or won't, only point out what others do, and that the controllers they are using currently have the technology.

If the ECM in the 2010 and 2011 contain a re-writable ECM, we should be in a position to offer support.

Cindy why would a manufacturer ever choose to make an ECM unflashable? There are always ECM updates coming out...and from a warranty point of view, having to replace an ECM vs reflashing it to fix a simple driveability issue seems kinda dumb...

But then again allison somehow couldnt figure out to make the new 4th gen TCM's read/flash in faster than 45 minutes either when their 3rd gen TCM's designed in a mid 1990's can be reflashed in 5 minutes. :rolleyes:

I agree Ben it does seem silly not to be able to reflash. Why they don't allow it I can't answer with any authority, only a decision maker from the car company could answer that. Perhaps it's a cultural thing - I really don't know.

Maybe an experiment.....?

Compare the cost of replacing non programmable ECM's vs dealing with issues from having the ECM's reflashed via "non OEM standards". There's only one way to find out real world results (do it).

The sad part is I have heard that there are lobbyists who are trying to impose stricter fines for those that remove emmissions equipment and are pushing automakers to make emmission systems harder to defeat (locking ECM's would definitely be a start....).

Now that GM is in the hands of the government, lobbyist are going to have more say.....

I miss the 80's :D

Keep your LB7's

I'll keep my 8.1

The Allison TCM Reflash tool flashes the Motorola TCM at 250K can or 500K CAN. The Allison Dealers flash 4th Gen TCM's in less than 10 minutes.
