Improve your Fuel Economy and Performance

Guys, just bought this item from http://bluesparkautomotive.com/crtech2 . Arrived next day and fitted within around 10 minutes. Easy enough to do with basic given instructions. Now seeing a big improvement in MPG. Was currently on 32 MPG on display. Already showing 41 MPG on display. My route/driving style hasn't changed any. Also seeing a difference in Performance ie acceleration has improved. Vehicle spec, SD4 Pure Four door. Bought something similar for wifes Jaguar X-Type Sport 2.2 D Estate and her car gives on average 10 MPG More. Would like to hear of similar experience if anyone else has fitted this or something similar.

No way it would give a genuine 10mpg more, too good to be true!

Ivor,

Don't believe the display as the box fools the ECU.
Let us know what you get with a manual calculation.

I've got a tuning box waiting to be fitted soon.

Their advert claims "up to 10%MPG improvement" If you are getting 35mpg now then the best you can look forward to is a 3.5mpg improvement............... not so impressive and will take a huge time to repay with an initial cost of £280 +p&p

Sure as eggs are eggs. If your referring to my wifes car with her tuning box. Same route she takes each day to work and fuels up less than used to. She sticks to 60 MPH on the Motorways but was doing this prior to the Tuning Box being fitted.

My car, well, certainly the acceleration has improved, but I will report back when I refuel my vehicle. I was getting less than 400 miles to a tank without the Tuning box so I am hoping to achieve more traveling the same routes and same driving style with the tuning box. I will let you know how I get on.

The car has recently had a diagnostics carried out by the dealership at no cost and everything checked out fine. Was told by dealership that fuel economy should improve after 5k miles but I hadn't seen any improvement hence the installation of the Tuning box.

These things are mostly absolute rubbish. Anything that simply connects onto the pressure rail sensor is not 'mapping' anything. its simply misreporting the common rail's pressure signal back to the ECU, and or, simply increasing the rail pressure.

Do you not think if was as simple a this to increase fuel economy on the LRE, that LR would not do it themselves as a matter of course and save themselves from all of the hassle and negative press from low MPG complaints?

I'm not saying you won't see some changes in performance and you may, perversely get a few percent better on the MPG stakes. but 10MPG? That would be a 30% increase in efficiency over your current 32MPG. I don't think so, sorry.

I have one of these on my SD4 manual for the past 1000 miles and the mpg went from 37 to 42. (measured, not taken from the display).

Car pulls better and drive feels smoother.

Was the £150 bluespark 2 economy module.

I took it off whilst mine was serviced and fitted it to a friends SD4 auto who says his mpg has gone from 31 to 39 driving the same route to work every day. He claims that it also helps with the hesitancy on his auto when setting off etc...

Another One blown the Warranty for the sake of a couple of quids worth of diesel and probably invalidated the insurance too!!

Well, I'll tell you what. Why don't you take it along to your friendly LR dealer and let him know you have just found the answer to all LR's MPG woes right across all their vehicle range. They will thank you profusely because they could not possibly have invented something as tremendously important as this all by themselves. The company selling the Bluespark will immediately be acquired by TATA Automotive as a valuable R&D partner and LR owners the world over will rejoice.

On the other hand...

just about to take delivery of my evoque, I will be intrested on the manual results, I have had similar units on my BMW it defo helped, but since i been using fuely website its easy to track the real MPG
