Re: Anyone tuned a CRD yet?

772 N-m on the tune, yet claim not to exceed Trans. Hows that work?
Anyone know what the older 5SP trans was rated to?

Thanks for all the other information.
Exhaust I have 2 options HPX 3inch with Black Billet tips will be available hopefully next week, as it will be the first production run I will be eyeballing it first before it goes on the car.

If I am not happy with it then I will get a custom one made which I have already been quoted including black 4.5inch tips(I will supply), no mufflers, stainless.

My preferred option would be the custom exhaust but cannot be without the car as we have gone to one car.


Cold Air - we only have AFE at the moment and that is not fully enclosed hence why I am waiting for Banks DieselUSA) to release theirs hopefully its a 4inch MAF pipe.

So without the tune and both combined should give about 20 - 25nm, I am not getting the exhaust for performance the missus was not happy about me selling her V8 manual and I want to drop the EGT's when towing.

Here are some pics of the AFE CAI.

Re: Anyone tuned a CRD yet?

chocco nice, now interested in Banks.

Although seems strange they don't currently support in good old yanky terms "Diesel Trucks - Jeep"

Snuke,

I posted it so all information is there, is it possible that it is putting out 772Nm yes, but is it a true 772 well I dont know and until we get more Jeeps on a dyno we will not know, there are not enough dyno sheets

For example I have seen 2 bog standard dyno fgures now and they are both at 130 ATW the 2013 177Kw version, so as a baseline we are safe to say that that what our 2014 jeeps put out will be probably 133KW ATW, close enough.

Once I get mine dynoed I will start a thread "Post Your 2013/2014 Jeep Grand Cherokee Diesel Dyno Graphs", hopefully get a sticky and then everyone can make a informed choice regarding MOD's and Price Vs Power.

Sounds good in theory anyways.

Re: Anyone tuned a CRD yet?

Part of me has no desire to mess around with the car what so ever. However, I would like it to have better initial pickup, rather than the wind and shoot as it currently does. I gather that is turbo lag.
Apart from that, I don't want anything that could threaten reliability.

Yeah, reducing the turbo lag would make me happier... Still waffling on the bluespark but the reports I have been seeing on here are making me want it more and more.

Re: Anyone tuned a CRD yet?

A good CAI will help the turbo spool faster with or without a tuner. Look at the graphs. See where the initial rise in torque occurs earlier? The reduced inlet resistance helps.

The BlueSpark is user adjustable and has selectable power curves. One is designed to increase low end response and reduces turbo lag without increasing overall power. Combine that with a good CAI and you will notice a huge difference in responsiveness. The BlueSpark can be installed/removed in 5 minutes.

I may take a look at making my own DIY CAI. The location is pretty straightforward and I'm thinking I can fit a bigger (lower drag) filter than the AFE design. The AFE really only benefits from a higher flow filter since its open and "Cold Air" is less available than the stock air box. I was thinking of sealing the corner and using the hood to form an airtight box...if there is an inlet near that area.

Any hows see below, any more questions give Brendan a call direct or send him a email.

I wont be doing anything until I get my exhaust and cold air, exhaust is supposed to be ready next week and Banks CAI is another couple of weeks away, so all going well should have a tune in about 6 weeks, just the waiting is killing me.


1) Will I lose my tune if I take my car in for service and they do updates to the ECU ?? Yes, but a re-install is free of charge



2) Jeep have the 8 speed transmission in the diesel rated to 700nm after the tune the torque will be very close to this or above, what if I damage my transmission ?
There are different stages of tuning you can go for but we would never tune beyond the safe limits of the drive train.

3) If after the tune something breaks on my motor and Jeep wont fix it because I have a altered the ECU, what do I do ??? If your vehicle is in the new car warranty period and it can be proven the remap has caused the fault we will cover you under our 12 month Mechanical Breakdown warranty.

4) Do you have access to the Thermo Fan Maps/PIDS how do they work and can they be adjusted ?? Not sure on this sorry, hoping Celtic have answered.

5) If this is a Custom Tune and I have a Performance Exhaust and/or Cold Air Induction how is this tune optimized for my car if it is not tuned in real time on the dyno, all exhaust's are not created equal, etc ??? Celtic have the latest in AWD and 2wd dynos and these tunes are 100% developed on the dyno, we are the only ones achieving the gains we are without limp mode issues which others are getting.

6) What is the expected power and torque increase ??? Varies on stage of tune opted for.

7) The engine is making more power, will it run hotter and if so is question 4) possible. The engine will not run hotter no, we are not achieving our results by adding big heaps of fuel and putting egt temps through the roof which would be required to raise the temps as mentioned. Excessive fuel in a diesel is what raises egt temps.

8) I am in Victoria how do I get my car tuned if you are in Mackay ?? We are mobile and happy to travel to Victoria should you have a few to do, if not the ecu can be sent to Mackay and turned around same day in a registered padded express bag.

9) I have never heard of Diesel Power Unlimited what exactly do you do ?? We specialise in field service Diesel repairs and diagnostics throughout Australia and until recently PNG. We only utilise O.E.M trained and qualified Diesel Technicians and are regarded very highly around the Bowen Basin by many companies.

10) How many of these have you done and what if my ECU is bricked when flashing ?? I have not had an ecu bricked as you mention but should the worst case scenario arise our tooling has a recovery process to always go back to your standard software. Our 150 large dealer network have done many of these vehicles, exact numbers I would have to look into. I myself only starting the Australian dealership in May have done 1 of the WK series 2 Jeeps with some very impressive results as can be seen on our facebook page ( Diesel Power Unlimited ) until our website is up and running.
Thanks Brendan! Very helpful, the purple type, not so much.

For those that don't know, dynos measure torque at the wheels which is quite different to the specified torque figures of an engine.

Also, for those considering a CAI, the Jeep already has one. It draws cold air from the gap between the bonnet and just above the left head light. Some of the poorly designed aftermarket CAIs should be called HAIs because they actually draw hot air from the engine bay. So carefully check out what you are buying.

Re: Anyone tuned a CRD yet?

Hi all Brisbane owners, i'm organising for Brendan from Diesel Power Unlimited to come to Brisbane in the week starting the 23rd of June for a Celtic tune to my new 2014 Limited. If anyone is interested, either PM me or get in touch with Brendan Cook directly dieselpowerunlimited@live.com.au.

I am jealous still waiting for HPX to release the exhaust before I organise Brendan to Melbourne. Keep us posted.

Re: Anyone tuned a CRD yet?

Hey Chocco, can you clarify whether the HPX exhaust replaces the DPF with a high flow unit. Maybe I have misunderstood but i was led to believe that the DPF restricts the exhaust flow so any aftermarket exhaust will not provide a performance increase. Another local tuner who uses Viezu advised that an aftermarket, "High Flow" DPF was in R&D.
Have I misunderstood?
Either way, I figure 772Nm, if that's what is acheived, is more than enough. For now.....
