Re-mapping engine

Has anyone used a re-mapping chip on their car? I found this site http://www.chipexpress.com/products/3340/ it sounds simple enough and they have them for all models.
Any thoughts?

these are bull$hit mostly. Not sure about this particular one but i'd be great if it was true

If you treasure your engine warranty don't even think about doing it until the warranty has expired. Don't believe the claptrap that all the modifiers trot out about them being undetectable or removable as any condition outside the "normal" tune is recorded in the ECU log and flags up when the car goes in for a service. If you want advice about them then we have a member Pete Bell (Bell Automotive) who writes bespoke remaps for all Land Rover products

Agreed Tim, and Pete Bell does over OBD port re-mapping, with properly tuned engine maps rather than "fooling" the ECU with throttle sensor variations.

LR has issued a clear statement saying any aftermarket mods to engine mapping will immediately invalidate warranty on any Engine or engine related components, such as your DPF. The ECU may well record differences from Demand to Actual throttle response, so could be traced if suspected.

As for Economy improvement... if LR could get better economy and emissions they would be working tirelessly at it. The only things these units can try to exploit are the differing regulations...

Just look at the Web Site's reasons they say they can do this...

Many countries, for example, impose emission controls which are far more rigorous than those we have in the UK.
I read this as, so our unit will Increase your emissions

Other countries relate their vehicle taxation systems to power output rather than engine size.
So engine power can be increased.. but with more Emissions

Some, like the UK, impose higher taxation for different emission levels.
So the Emissions have been kept down for tax reasons, and our unit will increase Emissions

In many cases power is deliberately restricted for future use.
This statement says nothing, cars are designed to current regulation.

Finally the manufacturers themselves often produce several different performance variants of a given model.Yes this is true, but the taxation class is based on emissions (see above), so your emissions will increase, the ECU will be measuring things based on the setup in the ECU not the mods caused by this unit and so likely not dealing properly with it

If your Emissions increase, so does the waste in your exhaust.. and so does your risk of DPF failure.

So, Yes you'll get more power, but you'll also be putting more strain on components, possibly beyond the limit they are designed to take, and therefore increase the risk of premature failure.

With Pete's work he has mapped the engine properly on a Dyno and it's inbuilt into the ECU function rather than fooling the ECU. But either way this would still risk losing you your warranty.

Saying this though, many people do use these units and are happy with them, they do change the way the car drives, but you need to be happy you accept there are risks.

thanks guys...yes best to keep the warranty and not risk it.

Ive just turned over 71k miles using a TDI tuning box, i installed it at 1k miles and have had no problems at all.

When LRA did a diagnostic check about a year ago, due to water behind the rear view camera the only fault code found was for LED bulbs i had installed and nothing at all to show that i was using a tuning box.

My warranty expires on the 9/12/14 and i will leave it connected.

Thanks that's good to know Cutter, since mines out of Warranty soon...

Hi Phil,
I must say that i must be one of the lucky ones with an early model, no squeaks, rattles etc, and so far has been a pleasure to drive over the years.

Just the other day in a local car park in a queue, and the guy by my side said "what do you think of it then" and when i told him that it was three years old, he replied "didn't realise they had been out that long" how time flies..

Hi Cutter (also known as RAC to us )

Yes although I've had my share of silly little things like a couple of rattles which ended up in the headlining out fix, it's been brilliant, I think there's something special about the early ones , although my mileage is nowhere close to what you've done!

Yes when I discuss it with anyone, if I mention it's due it's MOT shortly, they look at me in amazement that it needs one!

Where did that time go...
