Hi there,
Was wondering if anyone had considered or better yet had installed already an ECU upgrade chip in the 2.0T...??

Am considering it in mine given i am stepping out of a 6.0 V8 and might need some horses under the bonnet to keep me sane...

6.0 V8 to a 2.0T

I can understand you not missing the visits for fuel, but how do you cope with the engine note?

 

[evan]

Yeah, is going to be difficlut... think i'm going to have make the vroom vroom noises myself....

On the fuel side the car is given to me by my company and they pay all costs... i just pick the car i want...

That's funny, I'm also stepping out of a 6.0ltr V8 and into the Q5 (around Jan '10 at last eta) but I've gone for the 3.0TDi. At least that way I'm only dropping from 270KW and 530Nm to 176KW and 500Nm. I think I will miss the instant throttle response, the sound and the fact that wheel spin is only a slight flex of the right foot away.

On the ECU uprgades, I've been reading that on the diesels, you not only get increased PS and torque, but it helps efficiency too.

I have a 2.0 TDI on order, and the prospect of having 200ps and lower consumption is very tempting.
Has anyone taken the plunge?

 

[Guest]

I have "chipped" my 2.0 TDI which was very straightforward and simple to do. Its a bit early (only did it last week) to comment on fuel economy but will keep my eye on it. I think the point is that with the extra torque there are less gear shifts and thus revs. tend to stay lower --hence less fuel used.

 

[stevepen]

which company did you use for the upgrade?

 

[Guest]

it was

http://www.dieseltuner.co.uk/

I fitted it myself. Engine is not on their website but they know all about it if you call them.

 

[Guest]

Thanks, that looks interesting.

I like the idea of a removable model anyway, for servicing etc.
I'll do a little more research on that!

 

[Guest]

I have one of the DTS units on order. It should arrive Thursday this week. I will fit it friday, run it for a couple of weeks and then leave feedback.

 

[stevepen]

Yes, let us know how you get on.

I'm looking at http://www.qstuning.com/

I bought a chip tuning kit from here http://www.chipexpress.com it cost ?395. Arrived the next day, took 15 minutes to install, can be removed for servicing too - so all good.

My car is a TDi s-tronic, with standard settings the power is increased to 200 bhp. Ive only been able to drive it once & it certainly seems more spightly. Sadly the next day i fell over & fractured my right ankle

so no driving for 6 weeks

 

[stevepen]

How easy was it to fit and can it be still used when in for servicing?

 

[Guest]

Finally installed my ECU upgrade from DTS (http://www.dieseltuner.co.uk/)
Very easy to fit, taking about 10 minutes. Most dificult bit was taking off the engine cover and locating the correct plug!! Due to weather I have only driven 10 miles but it definitely appears to have more power, pulling well with really good acceleartaion. I will give it a full test over xmas and report back.

The reason I chose the DTS unit is it is an inline unit encased in a seperate box about the size of a cigarette packet with two leads.To fit simply unplug the existing lead to the ecu connect one end of the new box to the removed plug and the other end to the ECU unit. It is easily removed and DTS will re-program it for free if you change car with a different engine.

Power increase is e 170bhp to 205bhp.
Torque increase is 350Nm to 430 Nm

Just noticed on their website they are doing a special xmas deal of ?70.00 off

Ok, back behind the wheel

. Ive managed about 500 miles since the chip upgrade. Whilst i was laid up i also fitted a K&N air filter. All i can say is WOW! what a difference. The engine runs smoother, has better pick up & doesn't hunt for gears as much. I am also getting better fuel consumption. I managed 44.6 on the journey to work the other morning. Fitted in 10 minutes - just amazing !

Best of all i rang my insurance company (Norwich Union) & for the rest of my current policy - Until May, less than ?12

Hi audiman

Is yours on the standard setting as shipped or the max setting?

 

[Guest]

Just running the standard settings. I've had to take the K & N out because it was confusing the ECU. although quick, at max revs it was not running right . I went back to the standard air cleaner & it runs fine.

I think if you try the max settings it may cause the engine management light to come on. There is a noticeable difference on the standard settings. I think it boosts the power output to about 200 bhp.

 

[DTW]

I used one of those plug in tuning boxes on my old TDi and it worked fine for about 4-6months before it kept going into limp home mode. The inlet manifold got choked up with carbon and it damaged a valve that cost me ?500 to replace. Nasty.

Anyway, I still liked the extra oomph it gave but decided that it wasnt worth being a tight ass with a ?37k vehicle and went for the full remap route this time.
I have 25k miles on my 2.0tdi Q5 with the Superchips Bluefin unit. Well worth it, my colleague with a 2.0T petrol A5 could not get away from me at all. Loads of grunt and economy is unchanged even though I can never resist a bit of turbo torque too often.

Check out the Bluefin, I've been well impressed and they warrant the engine if Audi wont as a result of the remap. You can remove it at any time and when you go on holiday you can lock it down completely.

In the Netherlands you can choose for Abt chiptuning by delivery of your Audi (or VW, Seat or Skoda) or later when you want more power, it's expensive but you'll have the normal guarantee from Audi NL and no problems bij software upgrades. Can you do this also in the UK?

2.0 TFSI to 275HP/390Nm
2.0 TDI to 190HP/390Nm
3.0 TDI to 282HP/560Nm or 310HP/600NM

Plug in boxes are bad news.

They interrupt the signals from the sensors to the ecu, and modify them, this is how they work. Its a bonus because they are so cheap and easy to fit, however the way they work is bad for the engine in the long term and can lead to problems down the line as described above with issues such as engine management lights, and fault codes being recorded from sensors due to the modified signals.

You are far better getting a proper remap either with blufin or similar systems as they will be engine safe in the long term.
