Hello!
So GM will be bringing their 2.8 tdi to market in the US with the upcoming 2016 GMC Canyon and Colorado. Im sure you guys at GDE are well aware. Im also sure you are all well aware it uses a newer updated version of the 2.8 that was in the Jeep Liberty.

So my question is, are there any plans to bring a tune to market for this engine in this specific vehicle? Thanks. If so, you may want to start drawing interest for it over the in the Coloradofans.com forums...

The engine in the Colorado/Canyon for the US market is a derivative of the "Cheetah" EU5 engine that Chrysler currently uses in the JK Wrangler (starting from MY11). It differs just in the packaging of some components and the fuel system, along with a slightly different turbo.

Based on our intelligence, the ECU used on the US market vehicles will be different than that of the ones currently for sale overseas starting with the 2014MY - it is the next generation of GM's internal diesel ECU.

Once we understand what the flash support for it will be then we'll of course add it to our list of vehicles for which we'll develop a tune for.

Keith-
Your reputation precedes you.
There seems to be several people who are anxiously awaiting your fine craftsmanship on the upcoming baby duramax.
(they must be upgrading from the 2.8 liberty as i am)
Drop on by their forum (its a pale comparison to LOST) and say hi... they would love to hear from you.

Our vehicle is still on order, as soon as it gets here then we'll get started to work our magic. The wait is agonizing as I'm sure you well know.

Keith let us know what your first impressions are of the stock baby Dmax are. I am having trouble deciding whether to play with the Liberty more or let it alone and order a Colorado after your tune is ready.

hey if you guys pop in to the ColoradoFans.com forum (under Diesel, specifically a thread titled "Potential of the 2.8" by yours truly), anything you'd have to say would be welcome

@GDE, I had a couple of questions. Do you think this platform would benefit from an oil catch can?
Also, I saw that Duramaxtuner.com has released their tune this week. Can you tell us how your tune will differ from theirs?
Will you be completely turning off the EGR? How much do you think the regens will be reduced compared to stock?

We stay away from the catch cans ourselves because they have a tendency to freeze up in cold climates at which point you risk to quickly push the rear main seal out of the block. With the EGR off the oil that passes thru the engine gets burnt harmlessly, so no cause for concern having is pass thru.

We've seen that some other companies are releasing tunes already for this application which is hard to imagine with it just having come out a few months ago. Ours will be ready come the fall once it has been validated in hot weather, the mountains, and under the most strenuous of conditions. EGR will definitely be off with our tunes and proven fuel economy gains included thru thorough combustion remapping. We have yet to see any other company that's putting in this detailed review and recalibration of the engine's operation nor achieving such gains.

I think it should be safe to say that regen intervals would be on par with that we see on the Ram EcoDiesel. Our experience with this engine goes back almost 10yrs now since it has been used for many years in Jeep products, with the right combination of combustion parameters the engine's soot production can become quite low. The stock tune is regenerating all the time and also misfiring during regen, GM didn't seem to do a very good job in this area of the stock calibration.

Thank you for the response! I am sure your tune will be worth the wait. Assuming I have 15K miles or so by the time your tune is available, should I be concerned with EGR and intake deposits and if so, will it self clean once EGR is off or will I need to remove and clean those areas?

15,000 miles of buildup will most likely not necessitate a cleaning. The cleaning procedure would most likely take a day to do it completely.

I pick my truck up this Saturday(fingers crossed that the order arrives on time). I am really excited to see how your tune comes out on these. In my test drive I definitely felt the trans programming alone would make the truck an entirely different driving experience, more power/torque would just be the icing on the cake. Any kind teasers or preliminary results, def usage, power, torque, fuel economy, etc?

We got 38 mpg on a recent city driving circuit with a 45mph average speed. Seat of the pants performance is at least 1 second quicker on a 0-60mph run. We will not have dyno data until we finish the fuel economy development. The power-torque curve is a one day job. Fuel economy and part load driving characteristics is much more time intensive.

I understand for sure on the part throttle and fuel economy tuning. It is same on gas engines in my experience, anyone can knock out a good power tune but the magic is in the driveability, transitions from accel to deccel, light load to heavy load, etc. That mpg is amazing, based on what people are reporting on fuelly they are only getting 25ish so even 30 would be pretty damn impressive. What kind of DEF usage have you guys been seeing?
