Re: Anyone tuned a CRD yet?

Hi, I've just had a work with Celitc Tuning who remapped my 300c and they can now remap the VM engine in the new Jeeps, the only way to do this is remove the ECU but it dosn't have any tamper proof screws so there will be no way of the dealer finding it.

I have mine booked in for the 23rd so i'll let you know the difference between tuning box and remap, they predict 300 bhp / 483 ft/lb, this on paper looks less than the Bluespark but these are dyno tested figures and the torque curve should be better.

I'm not knocking the Bluespark in any way, it does the job well but a full remap with increased boost and parameters altered to suit should do the job better.

Re: Anyone tuned a CRD yet?

Any updates on the bluespark pro from those that have used one for a while. Some must have had the tune box in Australia for about a year by now. Regards

No complaints. Mine causes an engine code if set too high. Performance and economy are both good....choose one, you can't have both! If I drive for economy, it is the same as stock but has power on tap when needed. Mine is set to E7 which is 2 clicks under max.

Re: Anyone tuned a CRD yet?

Hi, I have now had my Jeep remapped for a week, it is quite a complex ECU to get into with regards to the ECU lock which also has a password but the bloke who came out to do it says this is normal now on nearly all new cars, so after getting passed the lock and deleting the password the map was installed.

At first the map worked ok but with some further testing we found that the over torque sensor was cutting the engine out and going into limp mode, the map was adjusted and we went for further tests and it was no different. We agreed I tested it for a day to see if the gearbox/diff would adapt like it has on other cars but with no luck.

After some discussions with his head office it was found that there is parameters for the torque sensor and after these were altered it was all sorted.

Now what can I say about the remapped engine, words really don't express who much more power it has over the Bluespark, its like a whole different car, the torque it has now just pulls like a train. I wasn't expecting that much of a difference but I can confirm now that the Bluesparks hp/torque figures are very optimistic, I now have a dyno proven 300h.p / 470ft/lb and it feels it.

If your in the market for a tuning chip I would also have a look at these remaps as the price is the same but the performance is a lot more, none of the work done to the ECU can be found unless it goes back to the Jeep factory.

If it stops raining i'll be a Santa Pod drag racing on Sunday so i'll see what she can do.

Many thanks Rob, this is very good information. Do you know if Celtic Tuning actually writes the map or are they just installing a pre-written programme? I notice you are in the UK - do you know if the programmer has any tune installers here in Australia?

I must say I have to concur with your general comments on the re-mapping tunes. Whilst we haven't taken delivery of our MY14 diesel yet, when we do I'll definitely be getting the ECU re-mapped. I obviously canít comment on Jeep tunes yet, but I can say that my experiences with remaps is similar to yours.

I have a Vtech (Sweden) tune installed on our MY13 2.0L twin turbo VW Amarok ute (also with the ZF 8 speed) - it was remapped to a Stage 2 plus the required exhaust modification. The difference between stock and tuned is night and day - totally different vehicle. Certainly, the 2.0L Rok goes much much better than the new 3.0L Jeeps I have test driven. The 3.0L diesel Jeep is unfit and lazy; but it has obvious potential so with a remap and freeing up the exhaust I expect it to be transformed similar to our Rok.

My tuners who did our Rok have told me that Vtech have also developed a remap for the VM 3.0L in the Grand and is available. This is an ECU remap, not a plug-in so much safer (IMO). If anyone is interested I can post the contact details of my tuners - they've done wondeful work for me.

Re: Anyone tuned a CRD yet?

Celtic write all there own maps which was why it was easy for them to make small adjustments, I did ask if they had dealers world wide, they do everywhere apart from the US, they've tried but no one wants to take it on.

The only way to map the Jeep is to remove the ECU due to the lock and password, its not as easy as it was which kind of sucks. The good thing is that now the ECU is open the possibilitys of further tuning is there, DPF removal, bigger intercoolet and bigger turbo, if your budget is there.

Be careful with who maps it and make sure they have the software to remove the password, I know the torque sensor was hard to find as well so it would be questions I'd ask now that I know.

Which ever one you choose I wouldn't choose a tuning box now that the remaps are available, you wouldn't believe a vehicle of this size can spin all 4 wheels in second gear, is was wet but still it's impressive.

Re: Anyone tuned a CRD yet?

Hey SRT ROB, we are familiar with the VM models of the engine in these as its very similar to the Land Rover Discovery 4 (LR/Jaguar) and the Holden Colorado 2012+ (GMC).

You are correct, the biggest problems with the modern turbo diesel ecu management is actually the torque limiters and this is also a part of the reason why plug-in "chips" are pretty much paperweights on all the really modern diesels. Its very easy to just add fuel and boost but this doesn't make the cut in modern diesels, mainly for this reason:

There was many very cheap/nasty plug in modules on the market a few years back and car manufacturers actually had a fairly big head ache from them as so many did damage to fuel systems by generally ramping up rail pressures to the point where pumps failed, injectors melted, pistons melted etc. It was also very easy to put the vehicle through warranty by unplugging the chips. So the manufacturers actually went to the ECU providers for a solution. The best solution found was to create limiters and if they were exceeded: Either- Manage the torque request to reduce power or throw engine trouble codes.

Its good to know there is someone abroad who has a good grasp of modern Bosch ecu technology, we've been sort of lucky in this area as we work with an OEM manufacturer using bosch so we get to see the logic first hand and how to get more torque requests safely without having trouble codes etc.

We are the only mob in the world (at the time of this writing) to have a full 3 inch turbo back exhaust for the VW Amarok twin turbo - off the shelf - (With 5 sensors in the exhaust like factory) that works just as if it was a factory fitted part, we do not have to define the xml's for starters... We actually have full factory definitions to start with on pretty much all bosch 15/16/17 ECU's.

Davo knows us (Vtech) from what we do on the Amaroks and we have done mainly stage 1 work on the new 3.0 liter VM's. We've had a few UK mobs try to the Australian variant amaroks done correctly, but we do have Australian variants of the same physical ECU but the firmware is very different hence why the drama.

Cheers
-Chris

Re: Anyone tuned a CRD yet?

Okay, so you guys are saying the bluespark is useless?? Or just that while it will boost performance you will only see 50% or 30% or whatever% of what is actually possible?

The Bluespark is a mild tuner that raises performance within limits set by factory programming by manipulating the input/output signals from the ECU. It essentially fools the ECU into supplying additional fuel. However, the ECU has fueling limits within its algorithm. Engine codes or de-fueling occur if the Bluespark creates demands that are more than what is allowed. Remapping the ECU and raising the limits yields better results but involves intrusive measures.

Re: Anyone tuned a CRD yet?

As was said above, a remap is a lot safer by altering all parameters to work together, instead of just increasing the fuel pressure which I must say with the Bluespark I was totally happy with, it did a fine job for what it was but my intention from the start was for a full remap after some great results when I had my 300c, which is still the fastest diesel 300 in the UK.

There is a noticable difference in power and now having a genuine 300hp I can honestly say that the Bluespark is not, I would say its around the 270 ish area which is good but if you want the best for a similar price go for a remap.

Re: Anyone tuned a CRD yet?

There is a very noticeable difference between a plug in "chip" and a real ECU tune.

As long as the tuner has a good reputation with Bosch technology, you'd be in safe hands...


Usually you also get no or very little fuel savings with a plug in chip, but a good ecu tune on a turbo diesel bosch should yield 8-14% GENUINE fuel savings... Our ford Ranger tunes are in the 12-15% vicinity everytime... Of course we tune for our local cetane rated fuel so that also makes a difference.

I'm quite happy to give a "demo" tune to a forum member on here only if they report back what they find.
