2012 D4 - TDV6 2.7 ECU remap - worth it?

[Fozzie]

Hi all
While my beloved D4 is in with Comet getting its “mid-life” crisis sorted

Timing belts and coolant pipe

I am wondering about an ECU remap anyone have experience with this on the 2.7 engine?

Thanks
Fozzie

I had one done which upped torque to 508 Nm from memory for towing my block of flats - very happy with it in conjunction with EGR delete and adding EGT gauge - not that it ever gets above 600 even under duress!

I had a stage 1 remap & an EGR delete done & am more than happy. The car feels "lighter" to drive & (best of all) turbo lag is dramatically reduced. Definitely a little punchier but nothing extreme. Fuel similar although country kms marginally better.

I went with the Bell Auto Services (BAS) remap on our first MY12 D4 2.7 TDV6. I applied it almost immediately after purchase so can't comment much on performance difference. There's no shortage of power or torque and fuel economy running around town with the kids, to work etc. is around 10 - 11L/100km which were happy with.

Have since done the EGR delete and had deactivation patch applied.

Sorry lads what is EGR delete and EGT?

[Fozzie]

Also what do they mean when they say blanking plate?

Bell Auto Services (BAS) UK check out website and they have a blanking how-to download.

Pre 07 can be be blanked post 07 need the EGR software delete patch via IID Tool to fool the ‘puter.

EGR = Exhaust Gas Recirculation system that releases exhaust gas back into the air intake to cycle through your motor again.
EGT = Exhaust Gas Temperature - what will kill your engine from 700*C and above.
Google can often assist you with these things too.

Check the PDF guide linked below.

Post 2007 need both - both the EGR blanking hardware to be fitted aswell as the software disabling of the system.

Thanks all clearly a careful consideration- anyone recommend a mob in Brisbane to do it all ?

Order from BAS in the UK, you'll get a tool that also can do basic ECU fault finding.

Something other than the IID Tool?

It’s developed for BAS and is based on the Gap tool but with Engine CU functionality only.

Can also display outputs etc.

Option 2 is get the essential GAP tool and just order the Tune from BAS

I'm not familiar with Brisbanes Land Rover specialists but I'm sure Google will help you find. It's not particularly hard though if your relatively handy. I've already linked the instructions which you can review to see if its within your comfort levels.

I assume option 2 is the superior choice?

I will say that purchase of the ECU tune and EGR deactivation from BAS for both our MY12 D4 TDV6's was super quick and smooth. Would highly recommend.

I'd suggest reading the threads on snapped cranks etc on these over stressed engines. [bigwhistle]

None of those issues reported on the D4 2.7,which is what the OP has.

Although I get your point for the D3 2.7,and 3.0l.

Although the 3.0L is pretty good without a tune.

[DiscoDB]

Even the 2.7 D3 is pretty good without a remap.

But one theory on the South African 4x4 forum is a remap that gives improved bottom end torque can reduce the chance of a snapped crank as it avoids the need to use higher revs which is when the stress on the crank is the highest.

Interesting but my instinct is the opposite would be true. Like trying to ride up a hill in a low gear on your bike you are loading up the pedals, crank and your knees unbelievably compared to a high rpm scenario.

I suppose it depends on what induces the failure. Is stress or harmonics?

Hardly overstressed. In other vehicles the 3.0 is tuned far higher than the SDV6. (I wouldn’t take a 3.0 TDV6 beyond the SDV6 tube level though)

The D4 2.7s handle the upgrades easily. And BAS won’t overtune either.
