Anyone tuned a CRD yet?

I've done a bit of reading on here and have yet to see any threads regarding tuning the CRDs. Does anyone even make tuning software for these things yet? I have some friends with Duramax's and the amount of power you can tap from a diesel is unreal. Now obviously, you won't be getting anywhere near what they are getting out of the Duramax, but I would think it should be fairly easy to get a 50hp/100ftlb. bump out of a CRD.

Thoughts?

This from the jailbreak thingy eh?
Still thinking about doing that.

I saw 594 N-m, but more importantly, how were the actual pork chops?

Hello. I've had the Bluespark pro + boost for over 12mths and love it. I run it on "E9" which is maximum settings. There is a large boost to performance, even on standard settings. Easily installed in under 5mins. Even cheaper because we don't have to pay VAT.Great gains per dollar spent.
Happy to help with any other questions.

Sounds good but many running at the higher settings are getting codes. Aren't you getting any? What model Jeep have you got?

This thread has been a great read. I too had considered Bluespark for the pro + boost chip as they seem to have a great reputation on quite a few forums. During my search though I also found a local supplier called Lineartorq.

Their product seemed to operate similarly to the Bluespark module, however I did find they were much quicker to reply to my questions than Bluespark. It may have simply been due to the time difference in UK, but In most cases I had to send a follow up email to Bluespark before I would get a reply. They may have simply been busy I guess.

I also looked at DTUK as I was referred by a mate here in Qld who had one in his diesel Golf.

But in the end I actually opted for the local company Lineartorq, mainly as I always had a quick reply on email but also because I noticed that the quoted output figure was a little higher than DTUK in particular. Anyway I fitted it myself, which was super easy and have kept it on the factory setting for now.

So far I haven't towed with it but the extra torque from a standing start is excellent. My mate with the golf has now also purchased one for his Audi Q3 and reckons he gets an extra 40kms out of tank of fuel driving in Brisbane city traffic.

All in all though I think any of the three tuning boxes I considered would perform brilliantly.

Whether you made the right choice, I wouldn't know but choosing it because of a slightly higher figures is problematical. They can pretty well show you any curve they want, within reason. It won't be till we see some user figures that we will have a better idea. However, as you know, two cars off the same production line will perform differently, every dyno has it's own variation and every tuner does things a bit differently. So I expect actual user results to be all over the shop. Anyway, my point is one shouldn't stress over a few % difference in figures.

I suspected as much, they don't have the install instructions online for the GC.

The Lineartorq items look to be rebadged Bluesparks, or do many use the same hardware and then customise what’s going on?
They post the same figures as Bluespark, much of the language is word for word copied from Bluespark’s site too.
Lineartorq cost approx. double Bluespark. I could understand that if they were a local workshop setup, with an actual premises you could go to, so higher overheads… but they seem to just be some local guys with a website. Happy to be very wrong about that, as I always prefer to support local business’s, but this one’s a bit hard.

Thanks for the heads up, Snuke! Sounds like a bit of badge engineering.

I am torn about this. Part of me wants to get one, the other part says don’t mess with it, the last thing I need is a possible problem that then involves Jeep Aus and the wonderland of no spares.
Not to mention the ear nagging if there was a problem, oh jeezuz, that would be fun. Her daily driver, my desire for oomph causing problems. The end of the world is coming.
Think I just talked myself out of it.

AFAIK, no one has yet reported a blown engine or broken box that can be directly attributed to a tuning box. The CRD seems to be quite a robust unit. Most problems are peripheral.

If my memory serves me correctly (and sometimes it doesn't...lol)
Peter.T on here has set up the LinearTorq company

Hi Snuke,

Yes you are correct I am associated with Lineartorq.

We are having the tuning modules manufactured in Europe and have set up a company to distribute and service here. Our website was launched recently and thanks for the feedback on what further info you think we should publish.

As you may or may not be aware, there is a very strict criteria one must adhere to if wanting to use Paypal as selling medium. You can rest assured that we have qualified on all headings and of course this gives both buyer and seller a wide range of protection.

Our IT guru has decided to have a holiday and so you won't see a phone number or other contact details for a week or so.

I had decided not to advertise my involvement with Lineartorq on this forum as I considered it a conflict of interest but you have made that impossible now.

We are negotiating with fitters around the country and of course our pricing reflects margins and fitting costs as well as a minefield of costs in warranties and 30 day money back returns etc.

Of interest is that one of the most popular "Chips" (I hate that word) available and extensively advertised in Australia retails in Europe for around $300 and sells in Australia starting at $1495!

Our agreement with our manufacturer is tight and we are bound by commercial confidences.
Now that it is out there officially so to speak, I am happy to offer JG paid up members attractive pricing if anyone is interested. PM me if I can help.

We are happy to fit units on The Sunshine Coast if required and hopefully will be able to arrange fitting in other States soon.

Pete.

My confusion lies between using an interceptor type tuning box (Bluespark, LinearTorq etc.) or going for a proper ECU retune,
I know nothing, so take with the huge ignorance I have in this field, one thing I like about the tuning box is that it is basically plug and play. No need to take car or send ECU to get reprogrammed and no hassles when it comes to service and possibly having it flashed. From the little I have read, ECU reprogramming is supposed to offer bette results though.

As Lineartorq website is now, I couldn't buy from it as there is no contact number, no ABN, no address, the website has a hidden Whois (as it should), so I feel there is no security in the purchase. Their checkout is via PayPal though. The price being double UK doesn't help especially with all the feeling of local security not being their. Peter, if it is your website, sorry it feels harsh, just some critical feedback.

ARGH! Finally decided to pull the trigger on getting a BlueSpark... couldnt find the United States in the country list so I emailed them and asked whats up...

"Hi Ken,
Unfortunately we are not currently exporting to the US but we are looking to change this later this year.

Best regards,
Bluespark Automotive "

The GDE tuning process can be found here Green Diesel Engineering . I love the idea of a flash tool to upload custom maps oneself using the OBD plug. At last a reasonably priced user friendly re-map method. Only one problem, nothing for the WK2 as yet.
