First impression (only a short 10 minute drive), engine seems more responsive, possibly less turbo lag off the line ( will have to give it more time to tell for sure), set cruise control 70km, went up a slight hill that before the GC slowed slightly and revs would drop a smidge, with Bluespark up the slope no drop in speed and no revs drop not even a change in engine note!, did a moderate 0-100 and at just over half throttle if felt as quick as it use to at full throttle.
So far I'm happy, I will report again in a week or so.

Hey Yoda,
Any chance of a 0-100 with your foot to the floor??

Re: Anyone tuned a CRD yet?

For the new 3.0 CRD
No tuners have honest average before and after results on the same dyno or before and after 1/4 mile speed? Either transmission.
When they do that with results the orders will come especially when some good reviews follow.
Can't wait to order my VM 3.0 CRD.

Re: Anyone tuned a CRD yet?

I own a Ford Excursion 7.3 litre diesel that is moderately moded with custom ECU tuning, larger injectors, aftermarket turbo, 5 inch exhaust, and beefed up transmission. Its pushing 410 RWHP...was 275 stock. I have some experience with this and have seen the mistakes.

Words to the wise:

1. DO NOT TUNE/CHIP YOUR DIESEL WITHOUT INSTALLING A PYROMETER (EGT GUAGE) IN THE CAB.

A diesel is a heat pump with less dynamics and constraints than a gas burner. A/F mixtures do not have to be precise. More fuel = more power as long as you can get rid of the heat AND continue to make boost (to provide air). Failing to keep EGTs below 1200 degrees will anneal the turbo's impeller blades...remember they are in the exhaust stream.

2. A FREE FLOW INTAKE AND EXHAUST SHOULD BE USED. If you plan to tow, race, or any driving that pushes EGTs above the vehicle's safe limits, a free flowing intake and exhaust can reduce EGTs significantly. Someone on here commented about their chipped GC smelling burnt after towing...that is a sign of high EGTs and potential damage. An EGT gauge and observant driver would have prevented this. Refer to #1 above. Since a diesel is a heat pump, anything you do to make the pump have less inlet and outlet restriction lowers heat retention. A big inlet filter/air box mods and less restrictive exaust allows the motor to work harder without retaining high exhaust gas temperatures.

3. TURBO LAG AND BOOST ARE A RESULT OF HEAT. Heat spins the turbo (ok, expanded air which happens to be hot). More fuel burned makes more exhaust flow which makes boost. It takes time. A big shot of fuel from idle will make more heat and spool the turbo faster but will result in a lot of black smoke. A civilized diesel will have more lag but no smoke. Variable volume turbo inlet housings help but there is no cure. Hold your left foot on the brake and add throttle before launching to have quicker boost.

4. TUNED DIESELS CAN DESTROY A STOCK TRANSMISSION. A turbo can literally double the torque at lower speeds and most trannies won't live under these conditions. The new 8 speed looks beefy...we'll find out how its built soon enough. Just like the motor, heat kills trannies too. If you tow heavy and have your motor "turned up" with proper EGT gauge, intake, and exhaust, it may be able to work continuously at a level greater than your tranny can handle. The tranny has to dissipate heat also. A trans temp gauge is important if you tow heavy.

Having said all that...when I get my GC CRD here in the US, it will be chipped and hopefully DPF disabled. Anything done right can be done safely.

Keep up the testing and let us know what you find....but be safe, get guages!

Re: Anyone tuned a CRD yet?

Great write up. The Bluespark caught my attention for the same reason as it claims to reign in high EGT through increased airflow. One would hope that this claim is based on what can "actually" be acheived through the current inlet and discharge set up. I might be right in saying one or two members on this thread have OBD plug in's and might be able to confirm or otherwise?

That's an interesting claim they are making.

If its only a tuner, how does it increase airflow efficiency? Increasing airflow is purely a mechanical function on a diesel as far as I know. Injection pressure, timing, and duration versus rpm and throttle are basically what they control. The safer tuners can de-fuel as EGTs rise. That's a nice feature. All-out racers don't care about EGTs claiming you can't cook a turbo in 13 seconds....yes, there are diesel daily drivers that run low 13's in the 1/4. Really radical diesel racers are in the 10's with a 4x4 super duty pickup. 1500 RWHP/1400 TQ....amazing.

Gale Banks claims the GC's VM 3.0 block is reliable to 600hp. 200hp/litre is world class!

Re: Anyone tuned a CRD yet?

Would be great to tap into mods from these guys, but apart from chips the ECU mapping is all commercially constrained I would assume.

Agreed! There seems little doubt that chipping the CRD provides real power and torque relatively easily. However, it's the fuel consumption claims that I think are sus. They claim fuel is saved because the added torque allows the box to stay in higher gears longer. Sounds logical so far. So by that logic a Hemi WK2 would be more fuel efficient than a Pentastar WK2? I don't think so!

The Turbo allowing greater torque at low RPM is the magic sauce that the N/A Hemi lacks. The Ford EcoBoost gas engines have turbos (dual) and take advantage of this. The Hemi's displacement is it's disadvantage against the Pentastar. Also, a diesel can run leaner than a gas engine when under light loads...detonation is mandatory instead of destructive.

Most Super Duty pickups with diesels gain 10% efficiency with a good tune *IF* you keep your foot out of it. The greatest gains are made when the tune is a direct modification of the ECU instead of an add-on (piggyback) module. The ECU tunes typically control lower shift points and the lockup of the torque converter. Economy tunes will lock the converter earlier and more often. The feel is different....more like a manual shift, but the engine RPMs are lower with less losses in the driveline. with the increased torque, the vehicle still feels strong.

Yoda42 any updates about the Bluespark Pro yet please. Look forward to hearing how the GC performs on a trip. Regards

Re: Anyone tuned a CRD yet?

When tuning, admittidley with petrol engines, I have always added an exhaust system with cats removed along with any Ecu tune. How come this is hardly being discussed as a potential option here. Is it so different with an oil burner?

Re: Anyone tuned a CRD yet?

It's a little more messy with the turbo, DPF, sensors all over the place and a CAN that throws a tizzy every time you sneeze. No doubt people will do it, particularly those into street racing with little regard for the law or the environment. However, down here is Oz, we are more into long distance touring in harsh environments often towing something. We want the grunt but not at the expense of reliability. Reliability is king!
