Someone like BlueSpark is not necessarily increasing pressures, in fact they boast that they do not exceed engine specifications.

Still Solenoid, just a new Generation from Bosch

You gotta wonder how they are getting all of that power if they aren't increasing fuel pressure nor these devices adjust timing. The only thing I can think of is they are keeping the injectors open longer (more pulses) during the stroke, which uses more fuel. But the greater lower end torque can offset the increased fuel usage.

I definitely plan on getting the Pro+Boost Bluespark but I am the type of person that likes to know exactly how something works. Anyone know if there are any cold air intakes and/or larger exhaust systems out yet for the '14 CRD to help keep EGT in check?

I think that is for their mild settings only. I asked Bluespark two questions;
1. How have VM Motori managed to get more torque out of the CRD, and
2. Does Bluespark raise rail pressure. They replied as follows;
"Hi Bob,

1. I am not entirely sure what they have done, but usually it is a combination of improvements such as higher boost pressure, finer spray injectors, increased fuel pressure etc. Often though it is more that the older engine was purposely produced with a lower output so that next years model can be better.

2. Yes they do, our Pro model has fuel maps on there which can raise maximum fuel pressure, our Pro+Boost models can raise both maximum fuel pressure and boost pressure if you are looking for the best power output.

Thanks,

Jason"

Re: Anyone tuned a CRD yet?

Im planning to buy a 2014 3.0l Overland etc...my '08 Dodge Ram 6.7l has an Edge Racing tuning ((timing/edurance) stacked with a Mp-8 (increases rail pressure). Along with deleted Dpf and egr I went from 17-19 mpg to 26 mpg!
Im looking to push my 4x4 Jeep to 30+ mpg...plz h3lp Im wanting to chip and delete as I have no emission test to pass. Looking forward to future progress on the USA 2014 3.0L JGC tuners...

Yes, I was also looking at the Eco and the regular one not the Pro.

The one question I can answer for you Bob, that they gave a really silly answer to. They de-rate the engine to meet emissions standards (not marketing lol) in many cases. You can certainly change the power by changing the injection cycles but the vehicle may not meet emissions standards any more.

I do know with the edition of urea systems in North America, they have been able to jump up power outputs without changing fuel rail pressures. It was a common issue with straight common DPF systems that they needed to restrict injection rates to meet emissions. With Urea, they have been given more room to play.

So if a CRS2-20 Solenoid Injector can have up to 8 Injections per cycle, why would one jump immediately to increasing Fuel Rail pressure. At 2000 Bar, there is plenty of room to get more out of the engine without simply cranking up the injection pump.

Re: Anyone tuned a CRD yet?

Ya, doing some research on these boxes they are quite simple. Like in the Pro Bluespark, tells the ECU the fuel rail is at a lower pressure than it really is. ECU makes the high pressure fuel pump work harder = more fuel. Just add more air and you have more power. I honestly don't think you would get any fuel savings on something like the Pro. Pretty much there for the power...

Re: Anyone tuned a CRD yet?

Haha ya, why I am going with the Pro+Boost. I would not recommend that version to those looking for good fuel economy increase as the power gets addictive. You will end up cranking it to 8 or 9. If economy is your goal, I'd stick with the cheapest eco version.

I have a Nissan GTR with 700Hp/TQ and after a few years it feels "slow". It's amazing how fast humans can get "used" to something.

Re: Anyone tuned a CRD yet?

No doubt... at this point even my FJR 1300 (0-60 in 2.8s) seems tame to me and that thing felt like a rocket when I first got it.

So true! Seems we have similar tastes; Diesel's and sport touring bikes. I just let go of a BMW K1300GT, a very similar bike to yours.

Which tuning box are you going with?

Same... Bluespark Pro+Boost... for the Jeep.

I have a Power Commander III for the FJR but it seems to have just released some magic smoke and so is disconnected until I can pull it out and send it back for repair or replacement...
