Diesel Tuning Chip for Land Rover Discovery 4

It would seem from following Graeme's links (good find Graeme!) that the EGR removal modules for the EDC17 specific to the LR 3.0 ltr diesels were only added by Swiftec in July this year. Avon only released the DPF tuning capability last month. I'd imagine this may start to trickle through to other tuners now, but obviously it's a relatively new advance, hence the conflicting information we all seem to have.

Cheers,

Gordon

The gutting of the component innards for the Jag is that of the DPF (not the EGR valves) so that it can't blocked by particulates after DPF monitoring and cleaning disablement.

I'd like to find more about the necessity of probing an ecu pin on one or more versions of the locked EDC17 ecus, specifically if its required for my 3.0 and therefore what ecu pin and what voltage, eg 3V, 5V, ground etc.

I've been in and looked at this, as far as it says they can, I'm pretty sure I've emailed them before and they have said no, but that was quite a while ago, so I might inquire again, I did notice that it can be done remotely(I'm assuming diagnostic tool and Laptop), something I didn't see previously.

From memory Graeme, I think a member did mention the 2011MY D4 had an ECU change(gghaggis may confirm this or not) and it was a Siemans product that was mentioned(I've never claimed to be tech savvy with electronics:p)

Looks like there's hope yet, hopefully the remap and EGR can be done on the 2011MY D4 2.7L.

I'm in no rush, as the car is still under warranty.

Thank you Graeme and Dougal.

Baz.

I got a reply to my question to AVON Tuning

Hi Barry,

I thought the 2.7 TDV6 when out of production in 2010? or am I wrong?






Kind Regards

He is wrong but right for UK models.

Deleted: No selling in the main forum, please place it in the markets section

Thanks:)

Mods

Avon might like to know there is a market for D4 2.7 in Aus. and SA and also for the Ford terrorist as well.

There are plenty of 2.7's and 3.0 litre Disco's out there towing big vans and boats with ease and comfort.

If you want to compare stats then I guess it all defends on what your comparing it to, but if your comparing it to a Defender then don't worry. The Defenders are slow and underpowered in comparison and have a low tow ball weight so its near imposible to tow 3.5 ton with one legally, as most vans etc are set up with roughly a 10% ball weight and a Defender has a factory ball weight rating of about 250 kg from memory, where as the Disco is rated to 350 kg, or to put it more plainly 10% of 3.5 ton.

Heavy towing is not all about power either, a real bonus is that D3/4/RRS's don't need WDH's like every other vehicle does when the weight gets up and the LR air suspension and stability control works a treat on them, so you have picked a very good vehicle for towing that should do the job in comfort and be great off road or on long trips.

yes merci Terry
I have owned a 2.7 d4 for just two months, i bought a UK chip but have been tardy in fitting, Truth is that I'M only lkg for better economy
just I really like the d4, previous owner spent real do ray me on it, so its has all been done--i hope
made a box for it, kept it shallow so tailgate does not come down on it holds my stove water and can be used as a table, i shimmed the rhs tow spigot so there is little movement, 2.5mm chequer , 5052 grade0 5083 lid 3mm, cos that is what I had laying around
I will form such for free if anyone needs it

What about something like thisjust fitted to mine - hopefully attached?

Then again, I met a guy while travelling AUS last month who swears by his Roo Systems plug and play, claiming all sorts of wonders for economy and power.
