275 EU6 engine derating on track ?

Hmmm highly unlikely - on what basis would the car decide to detune... That would be mental to try and code in

More likely - higher temps, higher engine temps, turbo simply not performing as well

Even on a hot day a turbo car can feel sluggish

 

Could happen on any car, if the inlet->intercooler all reach and go beyond their capacity for heat or capacity to exchange heat to the air the performance will degrade along with the ambient temperature having an effect on the base line power like neil says.

The guy has 15 posts and owns a Honda, so.... you know.

 

Standard ECU torque and fuel limiting due to temperature. Not permanent.

 

I have a E6 275 and it indeed cuts turbo pressure when pushed hard. After half a lap on the ring I only have 220hp on the monitor and after a few minutes it comes back alive. Very irritating and hopefully a remap Will resolve it.

Yes there is remap to resolve it.
Should be under warranty .

 

Where did you get that information from?

 

From renault, works there
Will depend on the software already in there.

 

Ah right ok

Do you know how/when we can go about getting the remap done under warranty?

 

Go into the dealership and ask for an software update

 

Not always that straight forward.Some need a code entering, supplied only for certain fault codes.
And it will normally be on a customer complaint of the check injection warning the light on.
No harm in asking them to check though.

 

The info is correct.There is a new software that correct the over sensitive knock sensor. Sensor is calibrated over sensitive that he piks up normal sounds and think that there is a real knock, then the ECu lowers boost, ignition etc.

 

Makes sense.

 

Filled the car up with 102 on the last ring trip and no power loss... So it is the Knock sensor

Mine Will be going to the dealer on the 23rd of august. I called them and they only know if there is an update when the car is there and connected to the computer...

Let us know how you get on

 

Finally had time to pick the car up from the dealer. There was indeed a software update and on the first few runs it seems it sorted the derating. Didn't have the time of the road to test it out to be 100% Sure but I'm pretty Sure it's fixed!

Thanks for the update, I collect mine in a few weeks and I'll insist on an software reflash

Has this update reached the UK yet? Is it a quick/easy job?

 

It's just a software update so it isn't difficult. Don't know how long it takes.

Yes it's in uk, has been for a while.
Normally takes up to half an hour.

 

I can confirm this!

@nickfrog I did also see the Pistonheads thread, and this is also being discussed at other forums across Europe.
UK dealers are aware, and my car (due for delivery) has already been updated.

Not all SW versions need updating and it only seems to be a certain version of the EU6 cars that suffer from power loss due to the mentioned knock sensor mapping.

 

I have the SW version number somewhere. Must be in office, so I'll post it then!

Edit: not sure if my dealer are a RS specific one to be honest...

Edit 2:
Found it.
Apparently you need Software version 4500, calibration 183 (or later).

Renault apparently will only reflash cars were drivers complain about reduced power (boost) in heat, after giving it some stick, or after driving on very bad roads.

Root cause seems to be that the ECU responds far too sensitive on anything the knocking sensor does.

 

Is there any way to find out what software version my car has?

 

Haha!

 

FYI - Driven a March delivered Cup S. Problem was noticeable. Once driven spiritedly, car reduced boost (by feel and according to display), feels like timing is changed too.

Feels like the car looses 30bhp+.
Update time.

 

Derating???

 

De rating is definitely the wrong word. Due to a programming fault (incorrect software) the car (limited series of cars) may have less performance in certain conditions.

 

My Cup-S was delivered last month, software update was done for me before I took delivery.

 

Had another tracksession today and I had no deration what so ever so the update works!

Hi guys,
I am experiencing this issue too,
Rang Renault Nottingham this morning, very unhelpful, apparently they checked and there's no update available for my car?
Bollocks, they won't know until they check software version on Renault Clip, don't really want to take it there now, I know they will fob me off and I don't want to have to take the morning off work for that!
I will double check my software number on my Renault clip, shame it's not connected to their database or I would do it myself!
Thanks

 

Interesting one this chaps. My car went in today to have a rattle sorted and a new seat base for the recaro. I supplied them with the info re- software version 4500 and calibration 183 and it meant nothing to them. Can any of you U.K. Driver's let me know which dealers sorted this for you. I'll put Chris, the service manager, at Holdcroft Hanley in touch with them. Many thanks in advance.

 

Hi JonnyB,
Had the same issue today with Renault, the workshop controller asked me if I could get the details of any dealerships that have done the update on here, so he could speak with them also. I will get the guy I dealt with today to ring Holdcroft Hanley if you like so they can suss it out between themselves?? Haha

 

Mine went to "paesmans Hasselt" in Belgium, maybe your dealer could email them and ask for Tim [emoji6]
