Been reading another thread which someone says that the VRs has a adaptive learning programme???

Is this true and if so can it be changed just by thrashing or driving the car easily???

You must get the learned values cleared first and then thrash it

Not sure about it, first I've heard about it.

Even if it does have some kind of 'memory' I'm not sure its going cause a vRS to become slower. ?

I am pretty certain the ECU adapts to your own style of driving......over time ...anything up to 2 months....it takes a while to get the best out of a dragon tuning box

that was an april fools you know.

In that case, I'm a fool,

I'll wear the pointy hat and sit in a corner....

The ECU has an area of memory used for fine-tuning the parameters in the ECU. If you want it to learn quickly, you need to clear this memory so that it has nothing to work with.......

Being serious..

How do we do this?

Is it a dealer thing, or does the ecu adapt to your driving style after a matter of time?

I know this happens, but I didn't realise that such lowly cars as the Fabia had this capability, or am I being fooled again??

(serious question)

There is adaptive ecu you can notice it if you drive your car slow for a very long period of time after that you will see that it doesn't pull as it use to. Cure is to drive it briskly often and it will always be at it's best, but it might affect mpg a little.

I also recommend you to drive it briskly cause it's known fact that most problems with tdi engines occure when it's driven like granny and below turbo zone(ofcourse drive it like that when oil and water is properly warmed up and if you realy trash it give it a couple of minutes to idle before you turn off your engine).

The engine ECU will set certain parameters known as Rediness Codes after approx two drive cycles. These are cleared after erasing fault codes or clearing them specifically. They can be set purposefully but should set themselves after the cycles.

More applicable to petrols due to emission controls, but some areas do apply to diesels.

So, do i have to get these cleared at a dealer or can i just thrah the nuts of my Furby and it will "learn" about my new driving style?:confused:

I believe disconnecting the battery for an hour will cause them to be cleared.....

does it clear the security code from the radio too though?

Shouldn't do, the head unit should get this from the ECU anyway...

Rob.

I don't think it does if it's just disconnected for an hour, but my Fabia didn't have the stock H/U so I'm not sure. It will clear you computer settings though and you'll also need to reset your one-touch windows....

Chris

you'll also need to reset your one-touch windows....

:confused:

:confused:

If you press the, eg driver's, window winder and then release it, the window should continue going down. Same with going up - it only needs "1 touch". If it doesn't you can activate them - full details in your handbook

Surely this doesn't affect the turbo boost though - the ECU would only effect the car getting to boost RPM?

As I understand it, the ECU has 2 main areas of memory, the MAP which is where the engine operating parameters, etc are stored (this is what Jabba, etc tweak), and the volatile memory which is where the fine-tuning running parameters and trip computer data are stored.

The car takes the basic MAP and then overlays the fine-tuning parameters on top of them....

Chris

So it's best to take the battery off for an hour, reconnect it. go out and thrash the bóllocks of it and it'll remember your chosen way of driving forever? or will it simply change again after you have driven it slowly on a few occassions and back again when driving spiritadly?

Great, another thing I need to do this weekend

Thanks for the explanation Chris.

I can appreciate why it is setup to learn and balance the ECU accordingly - but surely there must be a safety issue here? Even if you do just potter around (as I do) you will still need to have the power in reserve in an "emergency"? Almost like kickdown on an auto when you floor the accelerator.

Hewesy

I don't think it really affects performance greatly, I think it just adjusts where the powerband may be accordingly to ensure you get a smoother drive

No wonder my car sounds like a bag of bolts when I drive it slowly

Never cleared mine and it works OK it will adapt slowly to your style of driving.....like I said before anything up to two months ......I've done this five times on different cars so I know it works
