Thinking of Superchiping my 2.0TDi Eos.:cool:

Any views, opinions and experiences.:D

I can't speak about the TDi, but I can tell you I am very :) with the APR-93 upgrade for the 2.0T; 200 hp goes to 252 hp and 207 lb-ft of torque goes to an awesome, and highly useable 303 :D

It depends what model year your TDI is. ;) I took my '10 model year TDI to get a Bluefin (http://www.mybluefin.co.uk/) unit from Superchips (http://www.superchips.co.uk/) a few months ago to tweak it to 170bhp, but VW (bless 'em) had apparently added some anti-tuning software in the ECU for 2010. :( Because mine was the first '10 model VW TDI of any car they'd seen, and they hadn't met that software before, they weren't willing to risk wrecking my ECU.

(That reminds me, I'll have to e-mail them to see if they've broken the 2010 codes yet. :rolleyes: )

If you do go to them, then I'd recommend the Bluefin rather than them just dropping a new map in. With the Bluefin you can swap between the upgraded and standard map just by plugging into the diagnostic port above the accelerator pedal and reloading the system.

Other friends I know that have had cars done by Superchips have been very pleased with the results - especially those with turbo-diesels. They say the top end hasn't had a massive boost in power, but the mid-range for overtaking has really improved. :)

Something to consider when thinking about uprating TDI engines with PDF filters......

The cost of replacing clogged PDF filters is very expensive [around AUD6000 from some reports] - the main cause of clogging is ash from carry-over engine oil being burnt in the DPF alongside the carbon particulates. The main sources of oil are leakages into the intake system from the turbocharger and crankcase ventilation system together with leakages past the piston rings into the combustion chamber.

I suggest it is not a good idea to be the "guinea-pig" for an up-rated TDI/DPF configuration unless you have a healthy bank balance or you are in a position to get tax benefits from any costs incurred. It is my expectation that an up-rated engine will be accompanied by increased oil consumption over time with consequent reduced DPF life. Your first cost may not be the end cost.

Are you saying that if I Superchipped my TDi engine it would bugger up my particulate filter which would cost a arm and a leg to rectify?:eek::eek::eek:

It is a possibility that you have to consider - uprating the engine places additional stresses on the components which MAY result in increased oil consumption over time. Hard driving may also have the same effect especially when the miles/kilometres incease so a combination of the two will eventually cause premature filter blockage.

The DPF filter is not a "pass-through" design but a barrier filter to catch particulates in the exhaust gas. The carbon particulates from the diesel fuel are burnt off during a regeneration cycle but ash particles from burnt engine oil collect on the filter surface and will eventually clog it. The filter cannot be cleaned and has to be replaced. The other option is to remove the DPF filter completely and kits to do this are starting to appear on the market; removing the DPF presents other problems with insurance and compliance with vehicle standards depending on where you live.

The level that Superchips take the engine to is the same as the standard 170PS TDI engine. :) That basic engine architecture is identical between the 140 and 170 engines (the economies of scale), so the increase will have a minimal effect (if any) on oil consumption and the stresses are those the engine is already designed to take. ;) If it took it to a level in excess of what the engine was designed to take, I'd have my own concerns.

Anyway, it's not as though you'd have you foot welded to the floor taking advantage of all that extra torque and power all the time. For the vast majority of the time you'll be using none of the added capability - as you probably don't use the full capability all the time at the moment, cruising at 70mph will use the same amount of power/torque before and after the change. What it would give is a nice boost for overtaking.

Had the reply from Superchips today. :) It would seem that they've cracked the anti-tuning element and do an upgrade for the '10 Eos 2.0TDI.

We are now able to offer an upgrade for your car, albeit not with bluefin.

It will gain a maximum of approximately 33 bhp and 61 Nm of torque, and in like-for-like use you should see an improvement in economy.

The RRP is £445 including installation and VAT

Shame they don't do it on their Bluefin unit yet. :(

I have the APR chip flash and it is awesome.

I also got the Carbonio air intake system, I have just had the injectors changed and the exhaust manifold polished and the sound and in gear performance is superb.

Had it on the rolling road and its up from stock 197 to 276hp, just awesome.

Decided not to Superchip my TDi EOS.

Missus wants a new washing machine. £445 should be enough.:rolleyes:

Why on earth waste money on a washing machine when you could spend it wisely on a Superchip?!!

Sad I know but clean underwear is more important to me than having more power so that I can go faster between speed limits/cameras/traffic queues.

I reckon it's biggest advantage is for quicker, and so safer, overtaking. :D Clean undercrackers are vastly overrated. :o

The £445 is pretty good value compared to the £800+ difference VW charge between the Jetta 140 and 170 TDI models. :rolleyes:

I sense that overtaking is the new drink driving.

People don't like it.

Some get the hump - flash their lights and blow their horn.

Then, after making an overtake you slow down to observe a justified speed limit they are six inches from your rear bumper.

I see that as well. You do a nice safe overtake, and because the person you overtake haven't the skill or forethought to do it themselves, they get all upset. :rolleyes: They then accelerate from the 40 - 45mph they were pottering aimlessly along at for miles and turn into Stirling Moss behind you. :mad: I guess some consider it an insult to their skill or manhood.

I enquired if Superchips expect to get the Bluefin working with the 2010 model year TDI, this is their response:-

It looks unlilkely that we (or indeed anyone else) will be able to remap cars with this ECU through the diagnostic port, and on that basis it is unlikely that we will be able to offer a bluefin.

I've replied asking them to book my Eos in next month to have the upgrade to 170bhp installed. :)

Will chipping get rid of the lag when taking off? Since the Flap motor was replaced, when taking off at traffic lights, it has a few second delay. The faulty flap motor, the take off was heaps better...

What lag? :confused: My TDI doesn't suffer any lag.

Excuse my ignorance, but I'm only an aircraft techie, what's a flap motor? - to me it's a hydraulic component that lowers and raises the wing flaps. Perhaps in the engine bay of a car it has a different name over here. ;)

You dont get a few seconds lag when you go to take off?
The flap motor is a motor that takes the air into the manifold. When I turned the engine off, a fan noise would keep running for upto 10 mins after the engine was turned off. Apparently mine had oil leaking in it... which is very strange. LOL @ plane wing flaps. If you google VW flap motor, it will give you a whole heap of info. VW have recalled them before.

Interestingly my previous car, an Audi A3 with the same TDi engine and DSG gearbox, had a delay on pulling away. At the lights I would take my take my foot off the brake and onto the throttle on orange knowing I would start to move on green.

With my TDi DSG EOS the response is virtually instant. So much so that too much throttle will spin the wheels. I assumed that VW had updated the box to remove the delay?

You dont get a few seconds lag when you go to take off?

Nope, no lag at all. I just push the accelerator pedal down as I let the clutch pedal up and off I go as I'd expect. :) In that respect I don't find it any different to any other car I've driven.

Ahh, you dont have DSG then? Maybe its a problem with the DSG...

Sounds like it!

I'm a luddite with a manual box. :D I guess it might be a foible of the DSG box rather than a problem. ;) I suppose it takes a moment to react to you applying power before it decides to engage the clutch, where as with a manual car the driver knows he wants drive so can do both at once. :confused:

IIRC, a DSG equipped Passat I drove had that momentary delay after pressing on the accelerator pedal before taking off. :)

No problem here, but mine is normally aspirated - are you sure problem isn't turbo lag?

Tim

Even if I put it in 'Sports' mode, still has the lag in taking off. I might google turbo lag and see what I can trawl up on it. Occasionally the wheels spin, but only in sports mode when the engine decides to kick in.

Even if I put it in 'Sports' mode, still has the lag in taking off.

IMHO and experience in a Passat, the DSG will lag slightly when compared with a manual transmission, but only momentarily as it has to sense that you're doing something before it can react and engage the clutch to get drive - with a manual transmission you're in control of the power take up. ;)

Anyway, back on subject, Chuggaboom is booked in with Superchips in Buckingham on 1st February to have the ECU remapped to make it into a 170. :) I might have to buy a red I to replace the silver I in TDI on the boot lid in-line with VW's labelling policy. :rolleyes:

I'll report back with some before and after comparisons when it's been done. The main one I'm interested in is the approximate 50 - 70 mph acceleration time in 4th gear - the main speed range for overtaking.

Why not go for the 187 bhp that Superchip claim they can achieve. :cool:

Are you going to inform your insurance company? You might have to change companies. :eek:

Even with the upgrade it will still have nowhere near the performance of your VFR.

Hey Ho.

Chuggaboom XI has now become the Eos I would have bought if VW had made it. :D

This morning I visited Superchips at their HQ in Buckingham to have the ECU re-programmed. :)

With the 2010 model year TDI the ECU can't be re-programmed through the diagnostic port using their Bluefin unit as can previous model years, so the ECU had to be removed and opened up. Because of the level the changes take place in the ECU, Superchips claim the re-programming is invisible to the VAG diagnostic computers. They also re-install the ECU plug cover using the new tamper-proof bolts the same design that VW use, so it all looks undisturbed on completion.

Superchips claim an increase of about 33bhp, taking it to about 170 bhp give or take a bit. More importantly for me, they claim a healthy extra 44 lbf.ft of torque taking up to about 280 lbf.ft. That torque compares very nicely with the 207 lbf.ft of the 2.0 TSI and the 258 lbf.ft of the 3.2 V6.

So how does it feel on the road? Initial impressions are very favourable, the response to the throttle is a lot sharper. My rough counting overtaking test from 50 to 70 mph in 4th came out at about 6 seconds before the tweak and just under 5 seconds after the tweak. :cool:

On the pub bragging front, looking at the differing performance figures for other VW models comparing their 140 and 170 TDI models leads me to expect a 0-60 mph time of around 9.3'ish seconds (about 1 second less than standard) and top end of about 137'ish mph (about 9 mph more than standard).

Is it good value? On my first impression I'd say most definitely. The tweak cost me £399, but that was discounted from £445 because I'd been before when they found they couldn't originally do the job - and one of the guys there is a friend of a friend. Given that the price difference between the 140 and 170 TDI Jetta is about £815, I reckon the Superchips route is well worth the money. :D

Just a matter of buying a red "I" to replace the chrome "I" on the boot lid to keep in line with VW's badging policy.

The final part of my 140 TDI becoming a 170 TDI - the badge, or to be more accurate, the red "I". :D

With my TDi DSG EOS the response is virtually instant. So much so that too much throttle will spin the wheels. I assumed that VW had updated the box to remove the delay?

Like wot he said, no lag and wheel spin if you boot it too hard

Like wot he said, no lag and wheel spin if you boot it too hard

convinced that it has something to do with my turbo. Was ment to get looked at 2 weeks ago, long story which I wont go in, but waiting on a call to get it back in to be looked at.

When you turn the engine off, the turbo should stop working yeah? cause when I turn the car off, it sounds like the fans are still running.

The turbo is driven by exhaust gas, and will spin for a short while after the engine stops purely on momentum. The electric cooling fan may continue to run if the engine is hot enough after it is switched off and will cut out after a pre-determined time.

This noise is certainly the electric fans continuing to operate after the engine is switched off. This is normal especially for a turbo-charged engine due to the latent heat that has to be dissipated from the cooling system. If this heat is not removed, localised "hot spots" may occur within the engine that could cause blown gaskets, distorted components or other heat-related problems

I would be VERY concerned if I did not hear the fan operating after switching the engine off after a trip longer than 15 minutes on a typical Australian summer's day. The fan operation is controlled by temperature sensor[s] in the cooling system.

This thread is great, it starts with a question about remapping an ECU and meanders through DSG transmission lag, the original query gets a few answers, then wanders off to cooling via turbos. :rolleyes:

Tangent springs to mind. :D

Do VW know if your car is superchipped when you take it for a service?

Not likely, unless the mechanic gets a surprise when he test drives it! :confused:

If you have Superchip Bluefin you can plug it in before you take it to the dealer and return it to the standard state of tune.

Cool. :cool:
