DSE project information

[langley]

Hi,
2000 DSE with EGR etc all standard with 97K miles on the clock.

Car is great and running well now, so im looking to experiment and play with it, damn engineers mind!!!

Wondering if there is anyone out there who i could have a chat with with regard to the following items, dont want a forum war, or to be told im stupid (i already know this) etc jsut so straight info:
- Manual boost adjustment, is there a requirement for a remap as has a MAF/ MAP thingy, what are the working pressures and what is sensible to cause no damage but improve it a bit
- Intercooler sizing, is bigger required for minimal tuning
- Decat and central silencer removal, DIY options

hope someone can help, read loads of threads but no real results posted and cant get hold of a few that have gone way further than i want to go.

thanks peeps

Has anyone here tried this:

Looks to be a clever and safe way in which to experiment within a given parameter. Or potentially incerase performance within the factory boundaries

Just fit a PSI powerbox or get it chipped. Pointless buggering about with boost pressures unless you're thinking of racing it.

And put some cash aside for a new gearbox if it's auto

Not really what im looking to do, but i respect your opinion.

By no means looking to race anything.

Just out of interest really, not looking for huge increases (or much really) just a more driveable car that wont chomp its gearbox as everyone screams with chips and powerboxes.

Purely, this is experimentation. Or curiosity.

Anything that causes it to put out more torque will chomp the gearbox

You can adjust the boost pressure but you need to be able to monitor it. Bigger intercooler expensive waste of time IMO.

Indeed iam worried about the gearbox, hence looking at boost control rather than boost increase. As with the information presented in the articles and a decat central silencer ectomy, it should be possible to increase boost repsonse without increasing or spiking boost.

Maybe im mental, barking up wrong tree. But i dont see the point in trying to "max power" the engine. As thats not what i bought the car for, im just looking to see if i can get a small increase in driveability with a large increase in self satisfaction.

You are not listening, increase in driveability = increase in power/torque mainly at the bottom end = chomped gearbox

There was a massive forum discussion (read argument) about boost pressures, dump valves, intercooler sizes, M51 tuning in general that lead to a conclusion of - pointless on the Rangies M51.....it was an epic thread....

So if y'all don't mind I'll sit here with me op2: and watch 'M51 Diesel Tuning II - The Revenge'

anyone wanna share me op2: ??

Under normal driving conditions a chip or powerbox will not crunch your gearbox unless the box is on it's way home to start with. However doing a lot of towing with one fitted could.

Apologies, i am listening i just think my understanding is missing.

Will the gearbox not handle the torque curve being shifted to the left? As by not increasing boost pressure i didnt think the BHP/ Nm foutput figures would be increasing?

I thought, by increasing the boost response to the prescribed level woudl just enable the current output levels to be achieved at lower revs?

Whatever im missing, could you clarify, as as much as like playing with things. I dont find rebuilding mistakes much fun in general.

Sorry Tony, if you use the power it certainly will, lack of torque reduction on shifts on a gearbox near it's limit as standard is the cause. towing will just hasten matters. Plenty of peeps have suffered the same outcome as mine.

Sorry, wasnt aiming to repeat everything ive read.
I just have seen that there are a hell of alot of knowledgable people on here so thought i would investigate my thoughts.

Shouldn't have bought a Range Rover then (sorry couldn't not do that one )

But you can't fit a dump valve to a P38 Ant.

 

[Datatek]

The EDC calls for a torque reduction on shifting gear, interfere with the torque curve and you affect the torque being applied when shifting, if you increase the low end torque there will be a corresponding increase in the torque during a shift. Work it out.

Okey doke, thanks for that.

 

[langley]

Thanks everyone, will can it there.

Cheers

No need to apologise - and yes Datatek and The Wammer are pure geniuses in their knowledge.....

We all gotta ask question or how else do we learn - it was an epic thread, one trully to behold Wammers and Datatek absolutly tearing this poor guy to shreds, he was obviously googling bits and bobs and then posting on here, Wammers and Datatek just tore his comments apart.....trully a pleasure to watch....

Never said you could - but that donut you were embroiled with thought you could and his mate (who works on engines and was a IC genius apparently) had done many conversions in the past and boosted pressure beyond belief.....!!!
