An ECO tune version would have the same fuel economy at steady start driving. It would just have a reduced torque limit and we could slow down the pedal response a bit to maybe eek out more mpg. The HOT tune is very fuel efficient if you drive conservatively.

Look in the forum topic 'transmission tune'. It is a separate module in the vehicle from the engine ecm, so no combo discount.

My intent is to get this tune but I want to be fully aware of all options and the benefits.

The trans dyno cal option is for folks wanting to test their vehicle on a chassis dyno. It will allow one to hold 5th or 6th gear to make a full pull without downshifting.

Just a few more questions before I purchase the tune for my Canyon. I figured it would be easier to ask here than on the other site. I would like to say first, that I am glad this has finally been released.

If the questions seem dumb, please note that this is my first diesel and my first time tuning...

1. if I were to change tire size, I assume I can contact GDE to re-calibrate the tune for a fee, what would that fee be?
2. when prepping for my state inspection, GDE mentioned that I would need to switch back to the stock tune for about 1 month, I assume that this is something that is done with the existing tools that come with the initial purchase and without the need to call GDE. is this still the case?
3. DEF would still be needed (at a slower rate than OEM). Do I need to worry about the DEF shelf life/effectiveness.

Are there any other tips to ensure the tune goes well other than following the instructions provided?

Thanks again!

1. On the website it is $25 for the tire size change.
2. Maybe a couple days back in stock for would be enough. It takes about 5 minutes to flash back to stock with the Autocal flash tool sold with the tune package.
3. If should be fine.

The instructions are critical to the install.
The GDE tune is safe to tow with as the factories safeties are still active. The ecm will defuel the engine if coolant, oil or egt approach the factory limits. We know nothing of the duramaxtuner, but their tune most likely turns off the safeties if they do not recommend towing with it.
BMW is too low volume to recoup the investment of developing a tune. We do not see this happening on our end in the near future.

Looks like 5 volt metal plugs and aftermarket, not Bosch for sure.
Remove the 7 volt etecno plugs, install the 5 volt mopar plugs and change the tune to the 5 volt logic. This is the best it will get.

They did a couple releases the last two weeks to address the issues. Hope we reach resolution soon
That VIN has not been tuned by GDE.
Did the DPF regen notice come on after the ecu install? You are fine to drive the truck. Best to send us an email vs. this forum, we check email more often and can get your order info that way to better assist. If the DEF gauge update (5mph test) did not run, the tank level will average to the correct level in the next 5-8 hours of driving.

EFI is a very rudimentary tuning tool and I find it does not offer much in terms of allowing a well balanced tune to be developed. It just does not have many mapped addresses, so you cant change the most important items."

How did you overcome these limitations with the EFI tuner, if that is the tuner you will be ultimately be going with?



We have been working with EFIlive to allow cax files to be used on this application and then we were able to address new maps into this file.
With a dpf delete, yes biofuel is feasible up to B100. Just make sure the bio is clean as contaminants will waste a fuel system in short order.
