And if you disable that there's no problem.
They also offer Vmax removal? What this?

And how do you guy the DPF?

Has anyone done all this?

Re: Tuning your EcoDiesel

Vmax removal is just removing the top speed limiter. Don't think many people with a jeep will be doing that as I doubt the car can reach it.

Not sure about gutting the DPF, but if it's anything like gutting a Catalytic converter it's literally as easy as removing it, and ramming a large rod through it until all the internals fall out.

Re: Tuning your EcoDiesel

I just read that gutting the DPF will not prevent a regen in most modern diesels. There is monitoring logic in the ECU that tracks if a regen has occurred within a certain number of miles and triggers a regen regardless of back pressure. I suspect an error code occurs if the sensors don't respond accordingly.

Only did it once and had a LOT of weight in the truck but it felt like it hit a hard wall at 118mph. I'm pretty sure this was computer limited not drag/power.

There's a video of an EcoDiesel GC at 126 mph posted somewhere earlier on this forum. 240 HP is enough to get you there. The tires are the reason it is speed limited.

I'm not looking for top speed, I mean it is a Jeep.

But I am looking to get the most out of the diesel and there is so much restrictions going on.

What restrictions? Mine has been flawless and I'm running the BlueSpark tuner. 0-60 is sub 7 second and fuel economy is excellent. Admittedly, if you are a short haul city only driver, any modern diesel is probably not the best choice. DPF regen requirements are a fact of life with new diesels.

Re: Tuning your EcoDiesel

I assumed the top speed would have been limited to 155 mph, as that's pretty much what all cars here in Europe are limited to. That's why I assumed nobody would be reaching it or wanting to reach it. But if it's limited to 120, then yes, maybe you are hitting the limiter.
