Anyone chipped a TD5

sqwirral - The thing to do is get them to check the exhaust gas temp after chipping. Some of the chips you can adjust - you need to make sure it isn't frying your engine!

Also make sure you tell your insurance company. You might want to ring first and ask if they will still cover it if you should choose to chip it, because some of the companies won't.

And yes, it will stress the engine - if it didn't stress the engine to a point of potential unreliability then the manufacturers would run those settings as standard. Most people (especially the chip companies) give the excuse that the car manufacturers don't tune the cars for the power the chips give because of the costs involved/emissions tests etc. Bollocks! It is because it stresses the engine more, and it is in manufacturers interests to err on the side of reliability rather than max power output.

Hi Ormus It's not about the speed for me mate my TD5 will happily do a ton as it is now, what i'm trying to cure is a nasty dead spot when you need the power the most i.e when you need to accelarate past a slow moving vehicle or nip into a gap on a motorway to get past a truck or when towing a very large caravan etc if you've ever driven a TD5 you'll know what i'm getting at you need to book a week in advance for the power to come in it can be quiet embarrasing sometimes. As for getting 30mpg mine does it no problem in fact the best was 34mpg. All i'm trying to do is make a great car better.
 
i said that in the first place but someone else said that its not true.

Well you were right, and they were talking bollocks!

I spoke to a guy who used to sell those "Smart" cars a while ago, and he told me that almost everyone who chipped theirs has blown the engine. The owner of the place had blown two engines in his own Smart car after chipping them. OK, maybe the 3-cyl Smart engine isn't the most solid unit around, but I've heard of a few blown LR engines that have been chipped too - including the new TD6's.

it certainly stresses the engine but not neccesarily over stresses it

Yes, not necessarily - it depends on how well it was built, how well it has been looked after etc. If you chip it and run it on full belt all the time I reckon at some point or another you are going to have problems. However, if you chip it and stay sensible then you'll probably be ok! Personally I don't have the money to risk a potential blown engine just for a few extra GG's!

Im not trying to cause friction here BUT if a chip/box is adjustable , its NOT a chip.

It is a box that has got a few cheap components in it to fool the engine in to giving more power. ( I personaly would not have one given UNLESS it was the only option available to make more Torque that most people need.

ive attached a picture of one of the MOST wide brand named COMMON RAIL (tricking) boxes out there , which i care not to mention.


A PROPPER chip in most cases is a phisical remap of the existing software maps inside the ecu, therefore there is no trickery involved.

A "chip swap" is needed on some older versions of cars due to the fact that the ecu has been fitted with a OTP (one time programable chip)
A re-map/re-flash is used on most of the new type ecus which have a Eeporm fitted which can be electronicily errased buy the tools connected to the OBD port.

Please all you you DONT get mixed up between a PROPPER chip/remap and a ADDON tuning box they are TOTALY different and work in different ways

Regards bell

Ps: you can make one of these **** tuning boxes for about £3, so why pay £400 ??

Deep yes but most tuners/power box sellers dont tell the truth about what they selling , nor even understand it , Exept me :)

hi mate,
perhaps speed was the wrong word to use. but if i wanted acceleration
in the 50-70 mph range, (in fact, in ANY range) i wouldnt have bought the disco tdi.
i certainly wouldnt be chipping any car unless i had the money ready for a new engine sometime in the future.
and i wont be driving a few tons of metal at over a 100mph with a 1900 style steering box system.

just my 2 cents.
 
I take your point, but either way it makes no difference to what I was trying to say!

Personally if I was to choose, I'd much perfer a plug-in box, then I can take it with me to a new vehicle - or sell it!

Errr Soooooo Its not a good idea then?

From my point of view it's a necessity, but then I wouldn't be too upset having an engine or gearbox rebuilt in 9 months time. All depends how much you need/want it.
 
So the answer to my question is NO, nobody on here has chipped a TD5, I think I'll leave it for a while till someone else chips one, just for the "knockers" of chips I used to have a chipped up 4 series Scania and put 140000k's on her clock without a murmour, she is still going now running containers out of Seaforth on the same engine/gearbox, Now that just brought back memories of running up "windy hill" flat out at 38 ton :) the look on peoples faces when you told them you where loaded.

Ive chipped about 1000 td5 eus in total also many many other cars , all with good LASTING results just like your scania.

and i chipped a scania 124.420 last week :)

it boils down to is exactley what you are saying , chipping is not for speed its for driveability and torque when needed.
 
Well I'm off to Bell Autos on tuesday for a chip and egr plug on my TD5 so I'll report back soon on performance. Reliability, we'll wait and see...:eek:
 
Let us know l3on how it gets on with the new chip in mate I need positive feedback and not "I think this or I think that" whats the gen with the egr plug, I used to have a pajero and heard about people blanking them off for some reason mine used to run ok without tampering with it.

Something that some people reckon improves the running of the car. In reality it rarely makes any difference, and the ones it does make a difference to is usually because the EGR was not working properly.

Matt.
 
EGR removal or blanking DOES help performance,

When the egr valve opens the air pressure from the exghaust that is spinning the turbo up is lost via the egr valve back in to the inlet side of the engine.
And the turbo looses momentum.

If you keep the egr shut/removed the turbo will always have positive pressure from the exghaust and then keep the impeller spinning in the turbo.And also helps to keep inlet temps down.

Why i choose if possibile remove the egr valve its self is for the reason of free flow, there is a big lump inside the valve tube that if its not used when its blocked off, so you may as well remove the big lump as well and help make the engine breath as well as you can.

Also there is LESS oxygen in pre burned air that is sent back in the engine via the egr so that makes for less performance.

I know a lot of people do this, but personally I can't really see the point, bit like fitting a K&N "cone" filter - under the bonnet! I'd also be concerned about the inherent higher combustion temperature causing problems, not to mention emissions.

I find it hard to believe that the small amount of exhaust gas which is recirculated will cause so much of a drop in pressure on the exhaust that it affects the turbo to the extent that anyone would actually notice, but I guess it is possible. However, as I understand it, when you are accelerating hard the EGR valve closes to allow full fat O2 to enter the combusion chamber (and presumably a likely significant increase in NOx!) Are there any issues regarding emissions once done?

Whilst we are on the subject, does the P38 diesel have EGR?
