Hello.

I have been emailing Bodsy about a gearbox and diff flush as a preventative measure as I hear he’s the man for that.

Unprompted he also replied detailing an engine remap which he says will improve performance without compromising reliability. He also mentioned doing an EGR delete along with making sure no adverse lights appear on my dash afterwards.

My car has been well looked after and runs well so I’m not really after a performance boost but it all seems quite compelling.

Has anyone got him to do all or parts of the work mentioned above - and how do you rate the benefits (or negatives if any appeared)?

Thanks in advance. Kit 2009 pre-facelift 3.6 TDV8.

On the 3.6 an EGR delete is a sensible thing to do given their propensity to fail and damage turbo's and engines. 2012 TDV8 Vogue (L322)

My 2010 3.6 had a remap and egr’s blanked and mapped out at that time car had 47500 miles it’s now on 105000 and it’s still running ace

Do it and never have to worry about the risk of the EGRs being ingested into the turbos. If I had a 3.6 I’d do it on day 1 of ownership.
Bodsy will transform your motor. Guaranteed.
Get him to also change the transfer box oil at same time as main box and diffs.

Thanks. Did you get your’s mapped as well? 2009 pre-facelift 3.6 TDV8.

We have mapped more than a hundred 3.6's and never have we experienced any reliability issues... That said! All our maps are tailor-made to the particular vehicle rather than a generic off-the-shelf map for a 3.6 or 4.4... So... I'd say "go for it" you will wonder why you didn't do it years ago...

Good to know. The email did mention that the map would be car specific which is good. Out of interest is the difference all about software versions or are all 3.6’s somehow slightly different so that they need individual tailoring based on current condition and parameters that are read before remapping?

Guess the standard maps are exactly that across the range (07-09 in my case). 2009 pre-facelift 3.6 TDV8.

You get a Monday engine and you get a Saturday overtime engine! Also milage, servicing and how the engine has been used all its life… That’s why the MAP needs to be tailor made sir…

That’s crazy…how do you know the difference? Is it readings and pressures? When I first started my working life, I was at Nissan and the mechanic there had a brand new Almera and used to floor it everywhere he drove, saying it would “open the engine up to make it quicker” lol

The last vehicle I had re-mapped was a VW T5. It had a hybrid turbo & large bore exhaust to help. It was done on a dtno (rolling road) with all factors taken into account. It produce 200bhp & the torque increase was awesome (I don't remember the figure). It was a very, very quick van, too fast for a van if you were in-experienced.

Not so easy to do an any RR as there are few dyno's around that will take a 4 x 4.

If I had the choice I would go for a remap using a dyno. Failing that, I would be happy with a generic remap - after all, that's what you get from the factory & I doubt if they had a version for each day of the week.

As a matter of interest what's the main differences between a mega-flush & a gearbox service that include a filter change ?

'Mega-flush' pumps new fluid around the box via the cooler hoses to replace all the old fluid with new. It may or may not include a pan ( filter) change and the machines that do this are not all the same or equaly as good so best to use a trusted outfit like 'Brodsy'
A 'service' just drains some (about 1/2) the oil from the pan and replaces the pan / filter. This can be a cheaper or more expensive option depending on who does it and what oil they use. Most people here to 'Brodsy' 2012 TDV8 Vogue (L322)

Personally, I would never remap a vehicle with more than 18-20k miles on it, the reason being that all the initial wear ('bedding in') will have been done with the OEM limits, suddenly increasing the available torque on a settled engine and drivetrain could accelerate ageing and increase the wear rates.

I have remapped hundreds of Landrover products in the past, not quite generic maps but it's simply not possible to write a remap on the fly to cover all possible variations, which are not all stored in the ECM anyway so you'd have to do several data collection drives in various climates, speeds, torque & rev ranges etc. - essentially replicate what the engine test & development department do, but for just one vehicle....

I can see the benefit in deleting the EGR valves, I would caution against suddenly applying the ability to produce much more torque to an older engine, not just to preserve the engine but to prevent accelerated wear on the transmission and drivetrain.

Of course, that's just my opinion and I'm not about to spend time providing facts & figures to back it up, because it's just one opinion amongst many.

Depends much more on how it's driven and cared for IME. A car in stock form driven aggressively on a daily basis and infrequently serviced will wear much more quickly than a sensibly remapped car driven occasionally hard and frequently serviced. Many OE manufacturers offer approved remapping services (eg Polestar for Volvo) which don't invalidate warranty so they must be not considered as life shortening. I've remapped cars but unless you are also upgrading hardware at the same time like exhausts, turbo's injectors there are limits to what is possible on stock hardware before safety systems and limiters kick in and stop the fun so most remaps are just nudging the power limits up to where the manufacturers set safe limits anyway. On a 3.6 I'd be wanting something that eased in the power to prevent shock torque loading on the gearbox and TC which ironically can be caused by faulty EGR valves so mapping these out is likley enough on it's own 2012 TDV8 Vogue (L322)

What I got on email from Bodsy about his map:

“The generic remappers tend to just increase the fuel rail pressure to put more fuel in and increase the boost pressure, sometimes by removing the boost upper limit, which is really not a safe method to remap. The BAS remaps (I'm a BAS authorised dealer) do a couple of different things to make it a safe, reliable remap for the tdv6/8engine.

Firstly, I take your existing engine ecu information, including the Landrover calibration files which are specific to your vehicle. LR have made many updates to the core engine software since your car was manufactured, so this will make it right up to date.
I then get the latest Landrover engine ecu software and match it with the relevant latest calibration file for your car. That is then modified to provide the remap, but with the added benefit of it matching LandRovers latest software. So if it needed to go to Landrover at any point, when they do a software scan, it will show it as the latest software, so will not be overwritten.
It also means that all of the other engine measurements that make it a safe remap are maintained, with the added benefit of the increase in around 40bhp power and 90nm torque.” 2009 pre-facelift 3.6 TDV8.
