It doesn't work like that tbh,I've popped a tuning box in a 2.0VAG and the mpg has improved,albeit by a small amount,but it has gone up.Thats at motorway speeds,around town its worse.

NewLabour

dba you haven't a clue what you are talking about so why not just shut up?

So far you've littered this thread with innacuracies so I think people would be best to ignore you. At least get the facts straight.

No diesel anniversary model? Tuning boxes? You haven't got a ******* clue, now STFU.

Tuning a car does not always make the economy worse (although often it does). If your tuning makes the car more efficient, and you then cruise on a motorway, you would expect consumption to be better.

If, however, you think "wow I've got more power", and then really boot it around you will end up using more fuel. You cannot get power for nothing unfortunately

As for Octavias, nice cars. If I was doing those miles I would have to think very carefully about get a diesel But, I'm just too addicted to the scooby burble. Get an Octavia to burble and I will sign on the dotted line

logiclee

Actually he is correct about the tuning boxes, after the first few weeks of trying them out most owners find an increase in economy.

Diesel Car magazine did a test on the Dragon, Tunit and PSI boxes and all gave 20-30% increase in available power and torque and an increase in economy.

Here's what Dragon say.

Do they make one for Imprezas?

Tuning a diesel? Why on earth would anyone do such a silly thing?

As for them being quicker than a Scoob? Oh no, no way. I personally wouldn't dream of playing against a Scoob in my taxi, why bother?

As for taking it on track as someone suggested, where might one do such a thing? I'd like to do that but I couldn't drive a greased stick up a dogs ****





Oh and tuning boxes are good, if a little limited in their range, and you will see pretty good gains - best bit is they are untraceable from a warranty point of view. Best gains will come from a "proper" remap. Same principles apply to modding a diesel as to a petrol.

logiclee

Hmmmmmmmmmmmmmmm



and one lap later.

I didn't say he was incorrect in claiming that, often tuning a diesel will produce gains MPG wise. However anyone who uses a tuning box is in my opinion an idiot when you can get a remap that works much better.

Thus he's an idiot for using a tuning box and not knowing that there was a diesel PD150 Anniversary MKIV Golf.

My remapped 330D gets better economy than it did before the remap BTW.

logiclee

There is the warranty issue.

A remap will screw your warranty, a tuning box can be removed prior to servicing or warranty work.
It's also the only option for most company car drivers.

Revo SPS1 removes this problem on VAG diesels.

logiclee

Yeh the Revo's excellent but it's bloody expensive unless you get it on a group buy or discount.
Full retail for the software and serial switch is over £750. Compare that to a couple of hundred quid for a tuning box and consider the revo only gives 170bhp which is only 10bhp over a tuning box then it's costing £550 for 10bhp.

The revo is also not available for older VAG Diesels.

If warranty isn't an issue then Jabba's 185bhp remap at £365 is a better bet IMO.

New Labour,

chill out dude,its the internet ffs! Apart from when I've obviously been taking the ****,I haven't posted any innacuracies.As for why I haven't got a remap,its a company car,so a remap is a waste of frigging time.I bought a cheap tuning box on Ebay for a bit of fun.They are good value for what they offer,it cost me 100 quid,and i can unplug the bleeding thing when i hand the car back.

If I wasn't covering 50k a year I would still be in a Scoob,so a tuning box is some small consolation.

You are all losing the point. Thankfully I don't have to argue the toss about which is better/more capable/faster as I have an STi 8 and Mk5 GTTDi on the drive.

Get it into your heads these are different cars built for different things and objectives. Yes the STi is a rally bread, tarmac destroying monster when you unleash all it's all to potent ponies from under your right foot, but costs an arm and a leg, guess at least twice as much as my Golf. Figures as one has 140 and the other 300bhp??

No the Golf is not quicker than a scoobie, you would have to look long and hard to find a VAG that could compete on an A road thrash, but could the scoob return 50mpg? No, but the harsh reality is the Golf would be all of 10% behind!

Different cars!!!!!

dba

I wasn't losing the point,I was winding New Labour up and unfortunately he failed to see the funny side,if indeed there was one.
Diesels are ridiculously easy to tune,and if you live in co car hell a remap or tuning box is useful for a bit of fun,thats just about the only point i was making.And yes NL,the mpg does improve.

chiark

Yes, the two cars are so similar mechanically, it's difficult to tell them apart... Even the wheels are gold, so they must the same underneath!

logiclee

Don't have to look too far there is one on page two of this thread. LOL

Jons Octavia TDi Elegance is far from a standard machine though even if he does like to play it down and fit SDi badges on the back.
Bigger turbo? big FMIC? Injectors? Remaps? Coilovers? Big brake conversion? Slicks for the track?
Nah he's never heard of such things.

i'd go for a alfa 156 2.4, booting it sounds remarkably like the scoob, well from inside anyway, 200bhp not sure about reliability but they dont sound like tractors.

Lee

iTrader: (3)

I'll have to check those out when I start to mature or do lots of miles

It should certainly have soul with it being an Alfa

logiclee

Yep I had one as a loan car when my 156 selespeed was in for a service. They sound and go well but the front end kept bottoming out with the weight of the diesel, the problem happens with the V6 as well.
The sound of the 5 cylinder diesel reminded me off the original Audi Quttro.

If you get one I hope you have better luck with your 156 and Alfa dealers than I did.

Cheers
Lee

NewLabour

You mean apart from the fact that they made a diesel anniversary MKIV Golf?

As for tuning box costing less so does the 'resistor mod' and that's bollocks as well. If you are going to tune a diesel use a proper map not some sh1te tuning box. The difference is really pennies when you consider the cost of the vehicle. Some people are very short sighted.

Agreed jabba are good but not switchable, REVO every time for a VAG car.

I think the 1.9 PD VAG engines are pretty good, but not the smoothest in the world. Have a go at the Merc or BMW diesels. They are very tuneable, but being a 6 pot they sound very nice. As an alternative, a Volvo D5 can see 225hp / 340 lb/ft.

A couple of options there.

BTW. I have raced my friend on a couple of occasions in my standard Fabia vRS. He has a UK scoob classic with turbo back exhaust [no cats] and uprated i/c. He can kick my *** midrange, top end, 0-60 or 40 or 30.....

The most fun i have had is a bug eye WRX [stock car] and i pushed him around some 'twisties'. But those weighty mothers aren't that quick anyway...

logiclee

There is a world of difference between a well proven adjustable digital tuning box and the resistor mod. A digital tuning box can be "mapped" to remove flat spots and increase fueling dependent on air flow, throttle settings, and temperature. They can also be set as to not adjust fueling until the throttle is depressed or the rpm increases, this way you don't get the lumpy idle that you get with the resistor mod.
The resistor mod just increase fueling across the entire rev range as it just sends wrong data back from the fuel temp sensor. Most modern ECU's will log error codes when fitting the resistor mod.

The revo is good if you need switchability but the maps aren't the best and at £750 retail it's more than double the well proven Jabba map that offers more power and torque.

Each to their own.

Cheers
Lee

NewLabour

lol@ the idea of tuning boxes being a viable alternative, they simply aren't as good. Unless of course they've completely changed in the last few months.

As for jabba producing more power maybe, well on Jabbas rollers anyway, they seem to get worse results on a 'proper' RR.

I'd go the REVO route if I had a VAG car, really you are talking pennies in relation to the cost of the car.

Still I suppose if I had a cheap older VAG TD a tuning box might be OK as a 'poverty' mod, saving money on an old banger etc.

Some people like to fit cheap tyres instead of F1's, similar thing with the tuning options IMHO.

logiclee

NL,

You have a very closed mind for such a new bbs member.

Take the company car driver, why spend £750 on a car that you don't own? The Revo is not transferable between cars either without addition payment to revo. If an extra £500 is pennies to you then you should'nt be intersted in diesel.

As I mentioned earlier the latest digital tuning box contain custom software exactly like a remap. Modern diesels run with excess air to meet strict emission targets, a good tuning box can increase fueling to burn with this excess air without extra visible smoke. The trouble is the amount of air is not linear throughout the rev range so a good tuning box map will need to take this into account. Diesel car did a test on the Dragon, Tunit and PSI box on a PD130VAG and all produced above 160bhp and would have passed roadside emission checks. Considering the warranty and company car situation and the fact you can buy them on Ebay for less than £200 they are very good value for money.

The Revo will no doubt give an extra 10-15bhp and an increase in midrange torque over the tuning box but I suggest most owners can spend the extra £550 elsewhere. That's perhaps the reason why tuning boxes sell so well.

And personally I'd go down the remap route but I'm not so blinkered as to not see the benefits of tuning boxes or the reasons why people buy them. I certainly wouldn't class people who buy them as idiots. That would perhaps say more about me than it would say about tuning box owners.

thanks for that lee

On the subject of misinformation I think you'll find thats the air temp sensor (inlet charge temp) not fuel... and also Revo SPS swaps a Revo version of the original map and not the true original.

logiclee

No mate the resistor mod connects to the fuel temperature sensor. On 04 and later models of VAG ECU's the reisistor mod logs a faulty Fuel Temp Sensor error in the ECU.

You are correct about the Revo putting in it's own original map although 99% of dealers won't know any different.
The Revo does check the ECU checksum before uploading so you can't use it to upload software on different cars.

Cheers
Lee

Cupramax

I was under the impression the resistor mod fooled the car into thinking the inlet temp was colder than it actually was and therefore the ECU increased fueling to compensate for it resulting in more power...??
