Thread: Diesel Tuning Chip for Land Rover Discovery 4

You're better off with a remap, like this one:

Chips are too low-tech for these motors.

is a remap, like the bluefin viable if your car is under warrantee? meaning can it be returned to factory by the user when taking in for a service, then back again afterwards?

just wondering because i was chatting to a bloke in the land rover club booth at the 4wd show the other day and the subject came up about remapping and the cost some people at the show were charging (about $2000). he said he just uses a chip from the UK , from the price he told me (about $500) one would assume something like the OP mentions. he said on his diagnostic tool/computer the chip reads/gives the same increase in torque and power as the guys at the remapping booth claim their does, for much less cost which he was happy about. he said before he takes his disco in for service he swaps the original chip back in, afterwards swaps his chip back again

I've had both. With the chip (technically an interception chip), there is no "original" chip to swap back in. With the plug-in chips, they are an additional item, not a replacement for anything.

The plug-in chips can give you as much performance as a remap, that's not disputed. However, the remap is the safer option (in general) than leaving a plugin chip permanently in the car. It can extract the extra power and torque "more subtly" - the chip is analogous to using a large hammer on a small nail.

Of course, the huge advantage of a chip is that you can easily remove it - so you can use it occasionally, in which case it probably causes no more wear and tear than a remap. It is also much harder to prove usage, if that bothers you.

There really isn't much correlation between the price of chips and their performance - some expensive ones are crap, some of the $200 delivered-to-your-door ones from the UK are very good. Most remaps tend to be good to very good.

Bluefin on the D4 needs activating on a bench first to take the map from the Bluefin. I think it did work for some early D4 2.7 vehicles but LR changed to Bosch anti mapping firmware.
Much better way of going than a chip. It is possible to get 720Nm out of the 3.0L.

720, thats sounds awesome , but i would think that the standard is enough in most cases, at least for me, even if towing 3K ...but it is interesting none the less and if its free power and torque (except the initial outlay) then it appears to be a good deal...i think i have heard a few times the mapping or chips do give more power, torque and fuel economy but if you use the extra power then the fuel economy disappears, cant have it both ways they say...i assume thats true?

did someone above allude to that chipping or mapping causes more wear and tear on an engine, e.g shortening engine life span? just wondering

I think the actual tune they sell limits it to under 700Nm but it is possible to get more.

Yes, I did. There's no such thing as "free" extra power and torque. I have a chip that claims 740 Nm at full boost. It turns my Sport into a black-smoke beltching rocket (chips are notorious for over-fuelling), so I rarely use it. It is unusable if towing, as it will always trigger an engine fault.

if you are concerned about your warranty a remap is completely undetectable! I also agree with other comments about chips being old technology in my opinion chips will be like having an old school TV in 5 years time, you will see them on sidewalks on hard rubbish collection days A remap is considerably better in that it changes a number of parameters to give better power, torque and fuel readings as opposed to a chip that effectively over fuels to give equivalent power results.
