Drone with DCT M4 MPE+Exhaust Valve controller?

erind · 07-06-2015, 10:25 AM

Hey guys

So I ordered the CG Precision VSC-2 Variable Sound Controller (Exhaust Valve Controller).

I'm curious to know if there is any drone with the DCT gearbox + MPE. Anyone that has similar setup?

Thx

I have a 6MT with the MPE and I'm running w/ the flaps open at ALL times. I get no drone at all at 80MPH at almost 3K RPM. There's just a SUPER SLIGHT hum; but it's a nice hum. The kind of hum that let's you know you have an exhaust.

Nice !
And beyond 80 mph? lets say 100 mph?

Surprisingly I took it to the top of 3rd which is about 100MPH and just placed it in 6th and it got quieter in terms of ENGINE noise but the wind noise started to pick up a bit. The car itself actually runs smooth as BUTTER at high speeds; kind of a bad thing lol.

I would assume you will get some drone..

I don't have MPE but I have DCT and have Valve mod done so they remain open..

Once the car hits 7th gear and anything above 65 I get some drone..

I would imagine if anything it will be a bit louder/deeper drone having MPE..

but with the controller mod if it starts to drone.. just close the valves

Should be good ...

I also have MPE as the other member said above w/ valves open. I have no noticeable drone at 80mph on the HWY.

Yea i can put the valves in oem mode if it gets too loud on long trips

I think the drone is mainly w/ the DCT folk since the car runs at a lower RPM at 80MPH the drone is more apparent. The higher the RPM the less drone.

I think if DCT owners cruised in 6th gear instead of 7th it would go away. But..your MPG would also go away with it lol

6MT here with MPE... No drone
Just lots of music to my ears and occasional backfires

Or drive faster in 7th gear

. We cruise at around 100 mph on the highway anyway so

LOL damn you Euros and basically non-existent speed limits. It's where the fun of the M cars can truly be displayed. Over here we have to do a mad scanning of highway patrol and it kills half the fun.

Possibly.

Funny thing is I barely ever use 6th gear unless I'm on the freeway for an extended period.

Drone range on this car is between 1.8k - 2.1k.
On DCT, that's like cruising around 65-71 mph on 7th gear.
It will also drone at higher speed if you are going uphill.

Hi AM4ZING, do the Manual Transmission M4's Fart (Over run) like the DCT's?

Or is it just a DCT thing?
