Hi Stevemus
Try adding a CR Powerbox inline and you will find that your diesel engine is more responsive as torque levels increase with lower revs and your mpg should improve as you use less boot to attain the speeds. I did this report some time ago when I had the lower BHP engined diesel Tucson- I still use the CR Powerbox now with my new 6 speed 138BHP Tuc and and am regularly returning 36-39 overall and 27/29 towing.
Hello to All Hyundai Tucson CRTD Owners. Vehicle Tested with the CR Powerbox is a 2.0 CRTD CDX
The CR Powerbox is a product that has been tried out on a Tucson for the writers benefit. It cost the princely sum of 109 Euros and the thing is the writer believes it actually seems to do what the information in the advertisement said it could do and it's modest cost also includes a 3 year Limited Warranty as well.
Firstly the writer is the type of person that no one in their right mind would call an engineer, the Powerbox was found easy to install although the German instructions are a bit vague if you do not speak German and it took the writer all of 15 minutes to install. The writer is a very sceptical person and he is careful over items he purchases, he recognises he should have waited for the Tucson to be checked out by others before purchasing one,(things have to do what they say or they are returned for a refund.(Nearly did that with the Hyundai but the writer acknowledges he enjoys driving it!)
Immediately after installation of the CR Powerbox it was noted that the engine seemed more responsive, the power seemed to be ready for instant action, It had gone from being a bit rough and somewhat hesitant whilst being driven, to being a real smooth operator. The accelerator seemed to require less pressure to obtain the speeds previously attained, and there seemed to be a smoothness that previously was hesitant in operation. Having just filled the tank it was the right time to try the CR Powerbox out.
The vehicle was driven at what the writer considers to be normal for Motorway driving, keeping to about 68 mph and increasing speed to overtake when required to do so and sometimes the odd burst of above 70mph. (you know what the writer means!!) Although when the weather reduced visibility speed was reduced accordingly.
The first trip completed over motorways and “A” roads at various speeds the mpg gauge (that American spec thing) was checked half way through the trip and was found to be showing 24.4. (29.28 UK) The trip completed and the Tucson’s guage gave an indicated 26.3 (31.56 UK) overall so fuel consumption was getting better!! The Tucson still had fuel remaining in the tank so a number of local short mileage trips to the Supermarket and into the local towns was undertaken, and a certain almost guaranteed amount of traffic congestion was encountered and the consumption dropped to 24.5. (29.4 UK)(ALL AS PER THE US GUAGE)
Later as the fuel in the tank got lower and the mileometer indicated that the vehicle had covered 401 miles it was refuelled and 53.0 Litres was placed in the Tucson’s tank refilling it to the brim.
The 401 miles on 53 litres gave a return of = 34.3498 mpg over varying speeds of between 5mph to 80mph (at differing times of course) and over many different types of road surface.
The US Guage gave an indication that the Tucson had returned an overall fuel consumption figure of 25.0 mpg US (30.0 UK) and was obviously really accurate! (Not)
Since that tankfull of city diesel the vehicle has been used part with, and part without the CR Powerbox, during the period with the gizmo box a return on the US guage showed 29.3 (35.16) and is the Highest that has been recorded to date! The gizmo was taken off after 130 miles and the tank now half full shows 25.3 mpg. (30.36) The engine seems to be less responsive and the writer feels it has returned to its as purchased condition. The writer has found that all of the figures above are an improvement on the previous ”best” by approximately 3.5-5.0 miles/gall
The writer has said that he noted that the mpg improvements seemed better at a constant speed of 60mph and the improvements in all cases where achieved when the engine was properly warmed up. Summing up, the writer firmly believed that this product works extremely well and he has mentioned it to others who have purchased the product and are in agreement.
A RECOMMENDED PRODUCT
The CR Powerbox is supplied by
http://www.mal-electronics.com remember you can order via Ebay and ensure that you ask for one that has the complete wiring loom, and an English installation specification (unless you speak German well). Euros 109 includes the postage to the UK. (This was the last known price (as paid by the writer)- proper price about Euros 278)
The MD of Mal Electronics speaks and writes in good English.
Here is the information from that site using their English translated version.
CR-PowerBox for all Common Rail Diesel Motorenadjustable Power up to 25% HP, Torque +30% Nm max.
The PowerBox CR works by modifying the electronic signals that control fuel pressure produced by the pump in order to optimize engine performance. The PowerBox CR increases fuel pressure at the pump to maintain rail pressure in the mid to upper operating ranges. In effect, pressure accumulates faster in the rail and is readily maintained to deliver more power and torque. The PowerBox CR engages when rail pressure is at or above 1,600 bar or 23,000 psi. The PowerBox CR includes plugs that are compatible with those originally installed in your vehicle. The PowerBox CR is easily installed directly to the common rail pressure sensor. With the instructions provided, an inexperienced driver can complete the installation in 5 minutes. The PowerBox CR will not override the safe operating parameters of your engine and does not change or interfere with ECU functioning. Other features are highlighted in the product overview below. Product Overview · For all cars with Common Rail Systems · Up to 25% increase in power and 30% increase in torque · Improved fuel efficiency (an average of 2.5 MPG!) · No interference to the Electronic Control Unit (ECU); original settings are not altered · Will not harm your engine, does not increase injection pressure · Can be installed by use of original plugs (no soldering required) · Will not alter engine diagnostics functioning, will not interfere with engine error code sensing · Does not change the service intervals required for your vehicle · 3-year limited warranty · Illustrated installation instructions included (Ask for ENGLISH version)
I wrote for the folks at tucson drivers dot commius (If the proper words used someone who is a hypocrite here change it to their site)I produced this to say about the type of performance booster I use. Others also wrote about similar items they purchased that do the same.
Hope this report helps
Itza.
