I had all my sport tdv6's remapped and the difference was really noticable. I have now upgraded to a 3.6 TDV8 vogue SE and I am thinking of having this one remapped as well. Are the claimed figures correct 4 to 6 mpg gain, 90nm more torque and an extra 50 bhp. Has any one had their 3.6 remapped and was the difference noticable. Any feedback will be most welcome.

I use the Superchips bluefin module on mine.

Makes a big difference to low end grunt, but can't say I've seen a lot of difference on the MPG.

A lof of people speak highly of JE Engineering, but I'm a bit too far away for them to be practical.

A slight downside is that it makes the car a bit smokey on full throttle.

I had mine done, would never NOT have it done now, its an amazing change.

As above. Used JE Engineering for my 3.6TDV8 and the results were great. Circa 5%-10% increase in MPG. Wave of torque to play with. See their web site for the numbers. I also had my current 4.4 TDV8 remapped by JE with similar results. Can't recommend it enough. MY23 D350 HSE

I've never had black smoke with either JE remap. MY23 D350 HSE

All remaps will give something out the back - you can't make a diesel go better without giving it more fuel *WHEN* it needs it - my remap suits me - it will give out a puff on hard acceleration, but that's to be expected. Be warned though - a remap moves the engine out of the 'safe' envelope, so if you are going on the continent, a blufin might be better for you so you can remove it and then keep up with traffic without fear of turbo/manifold problems

Thanks for the info will have a think on which way to go

I've never heard before that remap equals black smoke. And I've remapped a fair few vehicles and never seen any black smoke. I've had few flames out the back of a decatted remapped TVR Cerbera but that was planned My remaps have either been bespoke to the vehicle or bespoke to the model, all from highly experienced specialst sources. I have never used a 'plug in' remap or boost device. Perhaps it's those devices that are being referred to here with regard to black smoke? So where is the evidence for this remap equals black smoke theory? MY23 D350 HSE

A lot of standard diesels will smoke anyway but the smoke means that it is simply overfuelling, like flames from a petrol car its not good as your just wasting power at the end of the day.

It takes a lot of work so would possibly take a full day for a vehicle with lots of on road testing or ideally a private road where the higher gears and longer duration of high boost can be kept. FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

To clarify, the flames out the back of my Cerbera was on overun and agree it's not efficient but was fun at the time

As for my RR remaps (3.6 and 4.4), they have been model specific, their development has involved many thousands of miles and hours of testing by experts before release. I'm not aware of any overfuelling issues with either remap which should result in reduced MPG, when quite the opposite happens and MPG improves.

My point is, I am not aware of any evidence that says all [diesel] remaps result in smoke out the back. MY23 D350 HSE

I think he meant the overrun, which can happen as the fuel map doesn't respond fast enough (common issue in Denso ECU's). It's not a massive waste either, only a few CC's here and there, and considering you'll probably be doing single-digit mpg when getting the crackles and flames it probably isn't your biggest concern

I used BlueFin it's seems fine with a significant improvement in low down power but I only use the grunt occasionally, there is (as there always is any diesel including my unchipped previous new Audis and Mercs) extra particulate emission on full throttle. This is more noticeable at night in your mirror when illuminated by the headlights of the car you just passed .

I got to say the fuel consumption seems slightly down generally but overall I'm pleased, JE was a bit too far for me to go even with all the positive comments about their remaps. For me it's simple if you want more out you have to put more in - fuel that is, otherwise Land Rover would do it - fuel economy and decent performance are the conflicting holy grails for modern car manufacturers and there is no magic bullet. Geoff
