GIAC DSG Flash for R32

[Big Yellow]

Up or down doesn't matter to me, optimising (for either performance or economy) with the modified engine output would be the key for me to want a DSG reflash.

John if you want to know whats its like go see Arthur at Exoticars and ask for a trial. Make a decision based on what you like about it and what you dont like.

Makes sense to me! Thanks.

Just like an ECU re-flash "optimises" an engine, I would think the re-flash has the scope to improve a DSG.

Saying VW would have done it if it made a big difference seems a bit off the mark to me. By that rationale we should not reflash ECU's because if the engines are capable of running any better VW would have done it already. Clearly that is not the case for engines, so I remain unconvinced that it is the case for DSG's, however I agree that there would be less scope for improvement in a gearbox and the benefits are far more "argueable".

Personal preference would be a large factor.

Why is it a bit off the mark? We're talking about the DSG operation which is a gearbox not the performance of the engine/car.

If changing the shift time from 8ms to 2ms is beneficial because it changes faster and there is less wear on the gearbox wouldn't VW do this because it would lead to a decrease in warranty claims and it would give them bragging rights.

There are probably reasons why they don't change faster which only they know but it could be that the solenoids can't operate that fast and maintain reliability for example.

What I know is that unless the company that develops a DSG reflash shows a decent understanding of the gearbox by being able to change other more complex parameters and it's been used on the track for extended periods that it won't be going near my car given the cost of DSG repair.

An engine tune is a completely different area of tuning and there is plenty of data out there to support it and how it operates whereas the DSG is relatively new with limited data available on it's operation.

Ok so I think I'm getting somehwer here. So G-rig, you got the apr Haldex gen 2 unit? Is that right? Cost of $1950? Can you explain what this has done to the overall drivability? Sorry if you have posted this somehwere else please point me there and I will gladly read up.

Cheers

When Engine tunes were first developed, people were probably skeptical, but it's pretty much been proven by many tuners that they know better than VW (in my opinion of course, as for me, more power and better economy = better engine)

If changing the shift time from 8ms to 2ms is beneficial because it changes faster and there is less wear on the gearbox wouldn't VW do this because it would lead to a decrease in warranty claims and it would give them bragging rights.

Why didn't they give their motors more boost? That would have given more bragging rights, better economy, possibly even more engine life as the engine won't be working as hard.

Totally agree, I wont be rushing for a DSG tune, but I am interested in what it can or could do, and what the side effects are.

At one time engine tunes had little data to support them, people still got them, and many who didn't get them were still interested and closely watching developments.

Your talking sense in advising caution, however the development of this type of tuning interests me, in particular, optimisation of the whole powertrain.

Cheers for the wise words.

Wouldn't it depend how hard you are working it with driving style (in which case it won't be more economical either unless the extra power is created from air)? They seem to be detuned to improve reliabilty in all conditions, but more boost usually means more heat so doubt the engine would last any longer it would be the opposite.

[John Deere]

Agree, many variables including driver....hence the "possibly"

More power and better economy is BS IMO. Manufacturers have always made cars with warranty liability in mind so build cars detuned.

Increased warranty claims, higher fuel consumption, lack of differentiation between specs/models and so forth. All negatives in the opinion of the manufacturer as they won't sell any more cars but be lumped with more warranty costs. They also have to allow for different fuels and stupid drivers.

Side effects are a massive hole in your wallet

An engine is much easier to measure, you can monitor boost, performance, many areas can be observed for wear and tear and you can get a feel if something is wrong.

The DSG on the other hand can't be inspected without pulling it apart and untold damage could be occurring before any obvious signs appear.

Good luck with it you do go ahead!

This has gone wayyy off topic, and it doesn't look like its ever going to come back despite the rather obvious hints I was dropping with the deleted posts, thread closed.
