EFILive 2.8L Duramax E98 ECM Support

EFILive is pleased announce the first PC based tuner for 2014+ 2.8L Duramax (LWN).

The 2.8L Duramax using the E98 ECM is due for North American release in the coming months in vehicles such as the Colorado and Trailblazer, but has already been in use on a range of worldwide applications since 2014 including the Holden Colorado and European Opel and Vauxhall 1.6L CDTi vehicles.

Full announcement details, including software pictures and our dyno graph that delivered HUGE gains over stock tuning can be found on our website or in our newsletter. http://www.efilive.com/latest/2014-2...8-ecm-support/

Cheers
The EFILive Development Team

how about a factory stock file available? these were also available sooner than 2014 in europe i worked on the program when i worked for gm along with the 15/16 duramaxs

We have not released the .calz (mapping files) yet so a stock tune won't do much for the moment. The latest release that was posted does have the ability to read the E98 so people can hopefully send in some of the European car tunes and we can begin mapping those, the 2014+ 2.8L Duramax is covered off. If you are in Europe and have access to any of the 1.6L CDTi cars it would be great if you could get some reads from them.

Are you going to give us EGR control maps on the MY14+ 2.8L Duramax? Obviously the DTC's are there but control over the valve would be good. I know it's technically illegal for road use, this is for off road lol.

We have not looked at EGR controls and by the sound of it you don't want to actually control it right, rather keep the ECM happy if it is removed?

Could you share your stock read?

Thanks
Mike

I would prefer to have EGR control (flow, valve limits, actuator curve, temps, etc.) included if at all possible in the calz files. Also IAFV params while I'm at it. :)

We aim to pursue tuning these emissions equipped as soon it shows up at the dealer.

Thanks,
Nick

Nick, timing will be the key here, I will try to figure out EGR tables for the local Colorado's to get some idea on functionality, but as the US version is not released yet I can't give any firm answer to when they might be done. I soon go away on vacation for a while.

I would like to be able to close it in the software table and then turn off the DTC's which apply. It makes a difference to response keeps the intake clean and is worth .5L/100 when it was turned off on my 2013 Colorado. In the Bosch ECU in the 2012 to 13 model the EGR valve is open at all times to some degree unless you are at 100% throttle.

Hi there a little bit off subject but is the 2012/2013 Colorado able to be tuned with efi live?

No, that is a Bosch ECM with non GM software running it, we won't be supporting those.

Can we get a read from one of these trucks to start poking around?

Thanks,
Nick

Nick, last I heard the US release of this truck is now on hold until 2016 (yes, because of VW), so we can't give you any stock file to look at.

So are we still waiting on some trucks to get out in the wild? The build date on my Canyon is 1/18. Kind of hoping to get a stock tune before hand to start doing some toying around. I do have a neighbor who should get his around the end of this month so Im hoping I can get a stock tune in some way soon.

Plenty of our customers have them ordered but nobody has one delivered, hopefully they roll out this month and they aren't held over in to next year.

Yea I hope they get some out. Its bad enough we are 2-3 months over projected delivery of these trucks.

I would assume that GM wanted to make 100% certain they weren't about to be the next VW, they don't need a media disaster with this truck.

Stock ecm and tcm tunes.

Is that a USA built ecm read? Did you post the right stock file?

awesome thanks Rob!

Wow, looks VERY nice and simple compared to the Bosch crap of late. Tables all look nice and smooth too.

I got all excited, unfortunately these are Holden Colorado tunes, not the USA model.

We actually left out a lot of tables on purpose, they don't even use any coolant or intake temp correction on these, nearly all the correction tables are zeroed! Not sure if the US model will be the same but that is how it is for every other country.
And of course DSP4 will be ready to go from day one on the USA model (well, as soon as we get a read), there is already lots of Colorado's outside the USA running DSP4. C'mon GM, just ship the darn things already!

Oh well crap.....I have a Holden 2.8 Duramax tune already. I was all warm and fuzzy inside thinking we had something....haha

Darn Sorry guys, I received that from a customer and I'm on vacation so wasn't in the office to look things over. I had a premature posting problem.

Could be worse ;)

One thing is for sure there will be many differences between the USA release and the rest of the world as the USA is the only version of this engine that has DPF, Urea etc, neither of those are required in any other markets the Colorado is sold in. I hope GM haven't gone too crazy and throw us a big curve ball when they hit the streets. And before anyone asks, there will NOT be emissions defeat in the USA cals.

Canada?

Didn't even consider that Ben, should we assume they will have USA spec emissions or worldwide emissions? In any case we have not investigated any emissions parameters on the existing vehicles because there has been no need to remove what is not fitted.

Ross I think it's safe to say that the Canadian colorados are going to be identical to the USA colorados...except with a speedometer marked in those weird kilometer things. :grin:

Ill be the first to ask.

Are the trucks similar enough that one could possible run non USA files on USA trucks?

Lets face it, we are just along for the ride when it comes to what the US does...

That I don't know Mitch, I would expect all other modules in the trucks are the same (ABS, BCM etc), nowhere else has On-Star so not sure if that would be an issue or affected in any way if not running a USA cal. You just know someone will try it so lets wait and see :hihi:.

Meanwhile all of us over here are waiting for the hard parts to be developed for them, FedEx will be busy shipping a lot of parts overseas once that all happens.

If it's really that easy - I may take a REAL no phones vacation this year. Lmao

As long as the hardware between the engines is the same, and the ECM pinouts match, I dont see any reason why it wouldnt work.

Might have to change the VIN in the ECM to match the module environment identifiers for immobilizer and GMLAN crank-request though. Does EFILive support VIN update on the E98?

Yes it can be done the usual ways, but there should be no need to have to change the VIN if it is still the same ECM.

Good news update, some reads from USA Colorado's have been sent in as customers start to take delivery. Currently we are mapping them out (yes, they are VERY different to the rest of the world 2.8L OS's, damn GM!).
The plan is we will do a very quick closed beta test on these just to make sure there isn't any issues with the USA specific version (rest of the world has been going flawless for a while now), then we will do a public release.
So hopefully less than a week, a week? DSP4 for USA Colorado's is being worked on at the same time so it won't be too far off either (again already available for the rest of the world).

One thing is for sure to be able to tune the USA version you will need to be running the December release as this had some pre-emptive updates for these models so all we would have to release is the .calz file once we got ECM reads.

Great!!

Nice work Ross!

Can you full-flash the E98 between US and ROW operating systems? Or is the hardware different?

Now that I have a real read from one I'll have to see if it would be compatible or a disaster like what happens on E38's with incompatible year models. Currently the software won't let you though and that restriction is there because of what I just mentioned then on the E38. The ECM's are $1,200 here so we didn't want to see a bunch of them corrupted.
