A while back we at this forum came to the conclusion that the low spec model had different injectors, the mob at Roo claim they haven't. The parts search and landrover which was done on my vin number also suggested the same replacement part for injectors. Point I'm trying to make is Roo claim both specs tune up the same. I can't prove this however I can give a short summary of my on the road experience....

Firstly no noticeable change down low..... That doesn't mean there is none just didn't notice any.

Mid range- wow!!!!! It's a different animal, pulls like train!!!

Top end - wow. Also seems amazing. Just revs out so much easier.

The car now seems to rev so much easier and keeps pulling. Previously it felt quite flat up top and would run out of steam.

Without meaning to sound strange. It feels more petrol like. Just revs easier and relentlessly. I was hitting 100km very easy. Obviously booting it. As for torque I assume it's increased as to make a 2.7 t vehicle get up and boggy would require a boost in torque.

Unfortunately i didn't get a dyno result. They didn't offer it as part of the service. Apparently in Queensland you do get one... I'm disappointed that was the case but reasonably happy with the result nonetheless.

One of the added bonuses I felt was a slightly smoother more refined revving.. Kind of seems electric in its delivery.....

Please remember this summary is my opinion, I dont claim to be right, there are no measurement before or after, just plain old seat of your pants feel....

Thanks for reading

Which engine do you have again Bill?

Great feedback Bill..

Do you run an EGT gauge?
And did you modify the exhaust in any way?

Does the Roo systems upgrade close the EGR?

Hey chaps.

1. I have the standard spec 3.0 v6 diesel. It's the one with the lower state of tune. the 3.0lt v6 with the 8 speed auto was run across the whole range. Roo claims it's the same engine with a lower state of tune.

Ok the EGR question. Sorry not sure how and if it's affected by the re flash.

I did not change the exhaust as the Roo representative told me that the standard landrover exhaust was pretty decent and only minimal gains would be achieved

As the re flash still uses the typical engine safety parameters it is assumed to be reliable and still within landrover factory warranty. So they tell me.

Further discussion led to the fact that the 3.0 l can pump out almost 300kw safely however they feared the rest of the driveline might suffer. According to the tech the roo parameters are safe and nowhere near the limits of the engine...so they put it down to 240kw at he flywheel off course.

I just came back from a drive with the wife. She was astonished at the power and to be honest so was I. It become even more obvious to me now as I wasn't dizzy from the previous days events( it was a big day)

Sorry bout my lack of technical understanding. In a nutshell they told me it's safe reliable and won't void my warranty as landrover is somehow got a deal going with the chaps at Roo.

I can honestly say it's turned an animal into a wild beast. Yet it has mor finesse than before.

Glenno the head of Roo has that video on you tube. It's pretty interesting. As I said though I didn't get the dyno results. Still I'm happy.

It certainly kept the drive smooth and more powerful.

Happy days.

Please don't take this the wrong way as I'm not having a go at you, but...

I call bull**** on that one. That's something I'd want to see in writing.

Cheers,

Ditto......think about it. Landrover would not have a deal with anyone ....period.

Agreed

After having years of tuning experience in performance cars, I assume the car was individually tuned on the dyno, rather than a generic map being applied for the d4?

A lot of companies use generic maps however in mass produced cars these days the tolerances and power outputs vary considerably, not only from manufacture but how they are run in and their lives to date to the point of tune. I have seen differences of up to 40rwkw in factory cars.

If it has been tuned to the car, most engines these days will cope with a reasonable increase, however you WILL reduce the lifespan of the driveline. The weakest link you will find will be the transmission which will either need strengthening via a valve kit etc at a specialist transmission place, or regular servicing, however this does not guarantee anything. Just remember the increased power needs to go through the driveline components and being 4wd will be soaked up via the transmission or diff, whatever the weaker point.
I know there are differing opinions, and this is mine, purely based on years of experience in this area, many types of tunes even back from piggyback days, to the development of edit tunes on factory ecu's.

Enjoy the car as these tunes also,can iron out small imperfections in the factory tune give smoother power delivery, better fuel economy, tuned to personal needs and obviously more power.

Cheers

No offence taken.

You're probably right. Just probably blowing smoke up my a@;e !!! I can't say either way. Maybe they meant the individual dealers.

I'm just hoping the Disco 4 proves reliable. I never hope to have to test the theory. . Anyway. It's not my claim. It's what they told me.

I also went for a suburban drive today. Averaged 7.6 lts per 100km. Impressive actually. I did about 150km. It was a varied drive ranging from flooring it to grandma style.

The car just seems happier for better use of a word. It hums.

It would be nice to hear what the boys at Roo have to say... I'll ring them and request their comments. Hopefully they have the answers. They certainly have a good product. ( my opinion ) maybe they can post some comments regarding warranty and this so called agreement they have with landrover or the dealers.

As for transmission being the weak point usually. I agree. For the record I got the chip to make overtaking with my camping trailer easier. The other day I was left wanting on an overtaking excersise. The car went ok , but just not as well as I was hoping. That's when I did research to see if anything new had come out. Hence my posts. Hopefully the re flash will be used for economy and safe overtaking and will not prematurely wear the tranny. Thanks everyone for your replies.

Ok take care chaps

Bill

Thanks Captcam,

Basically the tune is dedicated to your vehicle alone, we extract the base fuel map from the ECU, send it away to be modified (to suit your needs), get it back and the upload it into your ECU. That is your tune for life, we cannot use it in a different ECU and we have it on file forever.

In theory this is a lifetime tune and in the case where the dealer does a software update etc we can reinstall the tune for a small labour charge to remove the ecu, flash the tune back in and reinstall it.

It's pretty simple at the end of the day.

Can do them for $1695 inc GST installed.

Sounds like a Bell Auto Services remap - but you can put it on and off as the owner desires and not take it back to the installer. The vehicle owner keeps the map file on their computer or the installing equipment.

The remap direct from BAS is a lot cheaper as well.

So if you are going to compete with places like BAS you may need to have a look at your pricing to be competitive, though your pricing would seem similar to other Chips offered locally.

Can anyone show me a diesel engine anywhere in the world that reliably produces 100kw per litre of displacement?

They did call it a fact right?
