Thought I'd share this with everyone as I came across it a while back.


In good old FCA dishonest style.

Stole this from myself from http://www.ecodieselram.com/forum/threads/whos-running-a-tune.426/add-reply

The issue with the factory tune is well FCA. they just stated with the 2016 press release that they intentionally detuned the Cummings so every year they can increase towing numbers without actually Changing anything. No one wants to see the same numbers every year and I understand that as well as the constant need for improvement but when the engineers admittedly detune an engine just so they can make it look better 6 years down the road when they introduce the tune and power it was supposed to have from launch? I find it dishonest and not very good business.

It's a necessary evil.

And I'm sure the same goes for the ED so that they can eventually factor in better numbers when sales percentages drop on the eco. Boost numbers to boost sales. But only when it's necessary to do so. It will take either another manufacturer to produce a serious and reliable high economy diesel that puts pressure on the ecodiesel's sales or just sales in general seriously dropping due to market.

Then and only then will we see a REAL factory tune come on this engine. Until then it will drag us owners along knowing it could be better.

Only it won't show it's face until there's competition. (Ecoboost obviously isn't a threat) Gm canyon/Colorado diesel or a gm electric hybrid full size that puts out some serious numbers; because until that point, ram is winning the numbers war. And until that changes FCA will do what they do best and hold out on the real tune they have in store

Very interesting commentary. I suppose future increases in capability for the ED engine will not be able to be retroactively applied to older models then, right? At least not from/by FCA.

That'd be correct.

This is why the After Market dealers make the tuners. They have figured out how to unleash the ponies in these beast. So wait a bit and you can a tuner that will let them ponies go.

It's more so regarding ecu mapping.

FCA is sitting on a 32+MPG ecu mapping for the ecodiesel but right now no other Truck on the market can come close to what the ecodiesel is capable of. And without competition there's no need for improvement. It will take a good while before we see more from fca though they do have it.

Piggyback tuners have always had issues of not actually unleashing hp safely because the only thing they access is fuel rail pressure and Jack it up which is of very little benefit.

I'm waiting to see something more

That's why custom tuning wins every time over piggy backs and "foolers".
