hi,

seen as a few of you have turned up the actuator arm on your megane for more turbo noise and different exhaust sounds has anyone with a dump valve tried this ?
john you did the video with the SQ valve can you another with the acutator wound fully out and mention to peeps on here if the D.Valve noise changes also

cheers

it will change, it will get louder in pitch cos its running slightly more boost meaning more tssssshhhhhhh

 

[meggerman]

i see in the thread above you talked about turning up the actuator arm on the megane for more turbo noise can i do this on mine for more noise and is it easy to do.

sorry if its a thick question but first time i had a turbo and i know nothing under the bonnet

thanks all

Craig when are you at K-tec?
i'm hopefully off down friday am to get an oil change
i can show you what has been done to the actuator

hi mate yes im down there friday i be down there for about 9am is it easy to do and would it take long, just want a bit more noise more grunt sound etc hopefully ktec will be kind and do it for me and put right oil in for me too

To be honest i was chatting with the guy who did the service constantly, so i probably put him off what he was doing!

It just makes more of a whistle through the exhaust, it does make the boost shoot to 0.9/1 bar for about a second or two then settles to 0.8 bar

I'm waiting to hear back from david, butwould be good to get down at the same time!

 

[craigyR27]

cool hope they will do it on mine then and yes hope you can get down there im sure i be around for a while down there

I've left my actuator arm in the normal position, when me and pau were testing out the remaps originally we both found on our cars that even if you wid the arm in the ECU still controls the boost. I fitted a boost guage to mine when I did it and without the map the boost did initially rise up to about 15psi but only once, it was like the ECU "learnt" the new actuator setting. As far as I'm aware the boost is totally ECU controlled, I'm no expert like, if the boost is ECU controlled whats the purpose of the actuator arm? Whatever the actuator arm is there for renault have put anti tamper paint on it so you can see if its been tinkered with (they have also done this with the map sensors)

 

[Jon Seal]

oh ps with the remap the DV is slightly louder but not really that much

 

[phil]

With the arm wound in it should keep the wastegate closed
increasing the boost
It must still open even when fully wound in, but i agree that is one clever ECU!

 

[andy bassett]

but wen you get the remap done can you wind the bar in and make it boost and hold or will it still drop back, surley the remap will allow you to wind the boost all the way and hold it to about 1 bar/ 18psi

 

[meggerman]

??? dunno what the answer is. but as john says antitamper proof paint will that be checked in an insurance claim ? :?

The remap will enable higher boosts so the wastegate will open at a higher boost level 1Bar ish
winding it in as standard doesn't work because it still opens it at a fixed level ie 0.8 bar if you get what i mean

I wouldn't advise going too far to be honest as it does have an electronic valve which is controlled by the ecu and this does pull boost back down to 14psi. It may be possible to bypass the valve but tbh the ECU on this car is a total piece of sh*t!

ok ill leave it were it is :!:

 

[craigyR27]

so should i leave the arm standard or can i give it a few turns just want a bit more noise if possible

 

[asmith225]

No paint on mine :?

DV definetly louder

Actuator Arm

This might sound stupid but were is the actuator arm, how do I get to it if I want to adjust it??? Bit of a turbo virgin I'm afraid. . .
No mods to the car yet so what difference, if any would adjusting it make!
