Possible ways of tuning the LML?

[THEFERMANATOR]

Who has the pin outs for the lml and the lmm, I'll just swap ecm's.

No.

X2 The LML uses a completely new style PIEZO injection system that runs at upwards of 200+ volts AC current. The LMM ECM couldn't run it even if you wanted it to.

In the near future it looks like we will have a cloned replacement ECM that will allow you to read and write.

CalEditor - That's great news ... I think

Stupid question for the day, is that gonna be a LML tune in there? or maybe a LMM tune? Obvious implication is will there be any software to support tuning the new ECM? Or will these be locked tunes / ECM's?

[CalEditor]

This will be the correct part number ECM. It will be modified internally. I am not sure how many we will make.
Option 1 -- We are looking at 1 per tunershop customer. The shop will tune the truck with out PCM, remove it and then install the original and then burn in the tune from the other ECM
Option 2 -- We build a cloned ECM for each customer that is a mirror image of the original except is has the read option. This could be an expensive unit
opyion 3 -- we are not open to discuss that option yet

CalEditor,

Are you planning on working with EFILive to develop tuning capability for the ECM, or are you going to be developing your own tuning software to work with your ECM? I'll make sure to keep an eye on this for new info.

EFILive will not be involved in CalEditors project.
CalEditor should also consider further discussions on he's LML tuning project on one of the many Diesel forums, not here. We DON'T want to be seen to be involved.

I will not sell my LMM or buy a new truck due to the ECM change GM has made, I think everybody who feels the same way should contact GM. If they can substantiate enough vehicle sales lost from people who have previously purchased their products, it may have a small impact on future development. I am fairly confident this will NOT matter for the LML platform though.

TDFDiesel you make a good point, but would they care? If LML sales don't drop then the answer is no. There would be outrage and revolt of they decided to stop people tuning the Camaro, but I think they know that.

I still think there main reason for this is just like teh recent problems with DPF deletes. Th EPA is tired of diesels bellowing out smoke, so they just went one step furthur to stop it at GM. A tuned CAMARO doesn't black out the highway with exhaust smoke(although some do with tire smoke), but a diesel can black out highways and in some instances cause traffic hazzards.

I have been saying that for years now. It seems as of lately all the diesel guys in this area I live in are more interested in rolling coal than actually making power/improving effiency of the engines. I just had an older gentleman call me today wanting to know how to make his 12V Cummins make black smoke. No mention of extra power or fuel economy, just wanted smoke!!!???? I have a feeling that all the stupid black haze/fog has caught the eyes of the right people in the right places and caused the mess that we are discussing here!!!
My theory with the LML is as follows: The damn thing makes 400 HP FROM THE FACTORY.... do you really need more for daily driving? Also, it carries a warranty for the next 5 years/100K miles, if your worried about emissions problems, they will be covered for a while yet. Maybe by then someone may have something fingered out!!
Just my $.02!!!
