I have fitted a larger intake pipe, 3" exhaust, aftermarket filter and have a "power tune" in the ECU. Work car so no more spending. It goes pretty good and is supposed to be 600Nm but unconfirmed. The thing I don't like is the ECU remap was a generic tune in that is is supposedly a one tune fits all so to speak which I hate. All cars perform different so should be dyno tuned to suit not treated as all one type are car operate the same. I think it's only "money for nothing" if you fit all these mods and don't get a retune of the ecu to get those mods recognised by the ecu

Generally speaking tuning houses will offer different tunes. Usually economy, towing or power tune depending on how you want your car.

What is the DPF delete?
I'd like to keep my DPF, just so I'm doing a little for the environment as are my solar panels on my roof. Willing to sacrifice the small gain in performance. I confer with you about Mr Plod but my vehicle is still under warranty and I have to be careful.

The Banks Monster is a straight through system with no restrictions. Don't know if my vehicle has a CAT on it. Pretty sure the US version hasn't.

In the process of getting a quote from Murchison Products in Brisbane for a flash tune and have asked them about re-flashes in case of overwriting.[/QUOTE]

DPF delete does that. remove the DPF out of the exhaust and a pipe replaces it. Are you doing worse for the environment? Hmmm having the DPF regen process, it dumps fuel straight into the exhaust stroke so you are basically wasting fuel to clean the filter. Better or worse I am unsure. I too am unsure without looking whether the export WK2 has a cat also but will have a look tonight and see as most new diesel have both from what I have seen but could be wrong.

So it has to be the trans not engaging, right?

Push the pedal a bit harder and get up to 1800-2000rpm and it engages with a jump and off I go. However, same spot with a warm drivetrain and the trans engages straight away, from 1000rpm I put my foot down and it instantly moves forward, no jumping off the line.

I do feel a bit of pedal to acceleration lag at times, particularly in eco mode.....
Those symptoms Benn0 I do believe are torque converter related. Cold tranny fluid is thicker so harder to move and get through the converter to lock it up.

I agree with the eco mode bit too and reckon partly that is a delay built into the pedal signal also. My pedal box in the amarok has 2 sets of settings - eco and sport. Put it in one of the eco and it feels like you have to put your foot to the floor before it accelerates. Put it in one of the sport mode settings and you have to depress the pedal less and less before you hit the spot like you are at WOT if that makes sense.

Was it a proprietary tune? That I could look up and research.
Do you know if your new exhaust was connected to your OEM DPF or was the DPF removed?
Is it a straight through system?
What's it sound like?

Cheers,
Richard
Hi Richard,
You could go to the HP Factory website to find out more info on the tune Jeep Common Rail Diesel « Horsepower Factory
The exhaust is connected to the OEM DPF, however they are working on a pipe that will delete the DPF. The system has 2 small mufflers as per pic below.
The sound is a deep rumble. Not loud enough for the wife to notice



Cheers, Craig

Re: WK2 3.0 litre eco-diesel 3 inch exhaust

Are those black tips Mopar ones Craig or HPF option? Please tell me not Mopar ones as I don't think they make them anymore and I want black when I go down the exhaust path

Re: WK2 3.0 litre eco-diesel 3 inch exhaust

They were put on by HPF. To be honest, I didn't know what they were going to put on.
I quite like them. They actually have a slight purple tinge in the sun.

Cheers, Craig

Re: WK2 3.0 litre eco-diesel 3 inch exhaust

I went to their website Craig but they only list tunes for the SR8. Pricey!
Still haven't heard from Murchison yet. I believe their tune would be specifically targeting the Jeep. I'll ring them on Monday if I don't hear anything by email.

Re: WK2 3.0 litre eco-diesel 3 inch exhaust

Would rather buy in Australia if I can as postage will make them even more expensive than the already crap Aus dollar.

Tunes are generally around $1200 as I believe the Wk2 you have to take the ECU out. There is no OBDII support for tuning yet. If there was they would be cheaper.

I'd much rather buy in Aus but I refuse to pay over $2000 for an exhaust when I can get it shipped out here for about$1200. Hate being ripped.

Murchison has the OBD2 tuning for some vehicles but not mine. 😩

Re: WK2 3.0 litre eco-diesel 3 inch exhaust

They definitely do tunes for the WK2 diesel as I had mine done there. If you look closely, you will find it.
HPF tune the Jeep on a dyno. It's quite a lengthy process
The tune cost me $990.00. Very happy with the performance and economy

Cheers Craig

I reckon $2200 for a DPF back exhaust is expensive too and wouldn't pay that. Stainless is not necessary unless you want it or are keeping your car for 10+ yrs.

$990 for remap is reasonable especially dynoed
