Who is that a reply to.?

No-one, it's a sales pitch

Funny sales pitch When it would not be for a profit !

Hope your not running a company LOL

It would be interesting to see the comparison, preferably backed with full testing.

In the retail trade it would be known as a "loss leader".

Therfore meaning non profit ...

As it's a new model car would it not be a development mule, for further sales.?

 

[GCLTuning]

The vehicle is new ...

However the ECU stems from the PSA group .This would not be a development project we have worked on a few of these vehicles with results second to none ...

I must admit I'm watching this thread with some interest, having has a remapped/chipped car (Subaru) that had no appreciable effect.

I'm also doubtful as to why car makers would not used optimised country-specific mapping, when so much else in a car is, I don't really see Ford, for example letting cars have a worse consumption than they could.

I do, however have an open mind, so am looking forward seeing some real-world results without a financial interest.

I also have a diesel car which provides an appalling consumption!

So, please keep us updated with the results.

Think you have missed the point completely, the object of the exercise is to compare volvos standard mapping of an Eco car, to that when a tuning box is added and then do the job properly by remapping the Volvo.

The guy doing the re map works for Audi Motorsport and has mapped the le mans cars, the Seat Btcc cars and other so I'm pretty sure he knows what he is talking about. It was he that started this experiment saying he could choose a tuning box that would get close to a remap for a fraction of the price, we said NO he couldn't based on the theory of how tuning boxes work so we will see, has he has put his money where his mouth is and the box is on the car. In one months time he will do the full re map.

The car will be dyno'd and dynamically tested after every change.

Can't see the issue everything stated is pure fact as it is happening, me like everyone else in the business is expecting the re map to be miles better, so wheres the problem

Was the Subaru you had a turbo? If so what model because my Impreza race car is remapped and that is a world apart from a standard Sti. Would suggest someone has not done a very good job in that case there are alot of cowboys out there who think they can re map, my Scooby was done at TSL no one better for Subaru other than maybe Prodrive

Correct me if I am wrong.

I spoke to a re-mapper who said that each given manufacturer does indeed configure each car to the exact same spec.

The reason being is that (as well as temperature issuse) the fuel in certain countries is less refined than in others - therefor there is a "safe confiuration" enabling any car they produce, to run safely/efficiently in any country.

Accoring to the re-mapper, this safely enables a remap to be carried out on a vehicle running in an average temperature country and having the benefit of using highly refined fuel, because there is less stress placed upon the car that runs under these conditions, enabling the bar to be raised without any danger.

Exactly as I understand it and exactly as the guy from Audi and countless others have explained it in the past.

He may map btcc & le mans vehicle's then again so do we ...

This is not the point .... the point its not the vehicle it's the ECU and the software that matters .


Ive yet to see a le mans or btcc vehicle with a tuning box !

With regards to economy we have achieved +12 MPG from the 320 CDI ....as far as we know this has not been beaten ..

ECU on my car is a Siemens coupled to a Siemens common rail injection system. Apparently Siemens ECU,s are a little trickier to map than the normal Bosch units. and suffer a dip in output between 2000 - 3000 rpm which appears to be endemic accross the range, a re map will fill this gap in optimising output. The tuning box won't be able to do this.

Not sure if you have got the idea I'm against remapping but if you have youare wrong I am totally supportive of it and have all my cars remapped at some stage.

I totally agree with you, I favour remaps, I'm just facilitating this experiment.

Are you telling me you map Works cars for Le mans or BTCC?

 

[GCLTuning]

The Siemens ECU is no more of a challange then the bosch ....

Slight varyations but nothing major

Well not been funny but some of the top tuners in the Industry beg to differ, they are renowned for comms problems.

 

[GCLTuning]

OK common problem with regards to flash protocolls but by no means with developing software ...

If you have byeshooter tools there was and update for this back is 2006 ...

dont quite know what "TOP Tuners" you have been talking to ... Claerly TOP Tuners Without top Tools

As planned tuning box was fitted at the weekend after first been checked over by Matt to make sure there were no stupid parameters in there. The box has to undergo a period of learning for 500 miles so we won't dyno the car until after this which will probably be this weekend.



Just found this post ....

1.

HOW an earth can you make sure there are no errors with the parameters when its generic even if the we factors you did not like you would not be able to do anything about it ...

2.

A tuning box cant learn a style due to not having any input from anything other than it self .

I think "matt" is not as good as he looks .

But he said it's *not* generic, indeed he said

Its made and designed in the UK, not generic and is fully adjustable

Why not just let the experiment run?

 

[merc07]

With regard to MPG this is shocking we will develop you a file @ Cost price for you to try out and will bet the Gallardo on it ... we will ruin any tuning box on economy and performance ...

Regards Gary @ ***

How do you tune your maps for economy against power/economy. Do you just tune the lower to midrange and leave the top end as standard? Reason I ask is I have a box at the moment with the parameters set for economy and that is how this unit is supposed to work - although just by fuel pressure.
