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.

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.

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.

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

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.

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.

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.

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".

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.

V6 Bandit · 02-08-2010, 01:35 PM

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.

Eosman · 02-09-2010, 08:57 AM

Tangent springs to mind.

louisg · 02-24-2010, 10:22 AM

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

Eosman · 02-24-2010, 11:29 AM

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

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.
