Few images of the SJ4000 WiFi dashcam and sample videos in my Duster:








Videos are in 1080p but youtube did some changes (sorry for the wrong dates):

So what is the current power and torque output on your duster? Was it measured on the dyno?

[::CMS::]

Started my DIY attempt for sound proofing my 2012 duster.

Following is my plan:

- Damp the whole car with bitumen sheets (3 layers atleast) including the wheel well plastic guard.
- One layer (2 for the floors and roof) of synthetic wool which is an alternative for fibreglass or rockwool that has good NR values, left over from my listening room acoustic project, may need to order more based on the requirement
- A layer of thin plastic sheet to prevent the synth wool from any liquid spillage eventhough the carpet has the pvc backing.
- EPDM rubber weather strip seals for the doors and engine bay.

I had damped the doors with 3-4 layers of bitumen sheets as part of audio installation. Started doing the floors and completed the front seats and 1/4th of the firewall, could not reach my hands more unless I strip the dashboard. So for the time being its fine. Did the damping inside the hood also.

Following EPDM rubber weather strip seals are ordered online:
- 5Nos x 4M (20M) BigD strip (http://www.ebay.com/itm/321874591022…)
- 1Nos x 4M SmallD strip (http://www.ebay.com/itm/301223943010…)
- 1Nos x 4M ZType strip (http://www.ebay.com/itm/261571804957…)
- 1Nos x 4M PType strip (http://www.ebay.com/itm/361082933601…)

All are with 3M double side adhesive backing. I will be using aluminium rivets for fixing it properly whereever possible, esp in engine bay. I will be getting the rubber chord only if its necessary.

Note: Make sure you disconnect the battery and wait for 1hr to disconnect the airbag module, I didnt want to take any chance for any false triggering. Also while disconnecting and connecting, make sure that the connector is properly inserted, slightly different than normal connectors. Once connected, connect the battery and check the ECU for any error code and make sure the airbag console light is switching off once started. Also did a layer of plastic shield for the module to avoid any bitumen eventhough its waterproof.


Following are the wip pics while damping:

Quick update after ~ 700kms drive after damping.

The tyre and road noise, vibrations, resonance are tremendously reduced. For those who are looking for the price of damping, ~1000/- for the bitumen sheet (20 \ 30m), need a couple of meters more for roof + ~1L fevicol sr glue ~340/- + a lot of elbow grease and effort + patience

How do you damp roofing? Any pics? Were you able to get the factory fit after removing the entire flooring carpet and redoing it? Great job

Yes, only thing you need to follow is to make sure all the lock pins are used and locked properly. Its not a difficult task to retain the factory fit. Roofing is still pending, didnt get time. Also the synth wool layer is also pending.

One more item I missed in the first post is to fill all the resonant cavities in the structure with synthwool is also in the plan.

Wow, excellent effort! I'm halfway through damping my car (doors, hatch, boot done). I've been collecting new weather seals and window beading for my car, but the EPDM seals that you've ordered piqued my interest.

Please let us know on how you're using those seals. I'm still suffering with wind noise in the cabin coming from these leaky seals.

Normal rubber wont withstand the harsh conditions in an automotive environment, EPDM rubber is recommended. It comes with 3M double side tape attached, however I will be using Al rivets to properly secure to the body where ever possible.

Please post few photographs of the doors with the new 3M strips. I want to understand the install a little better.
Is there more resistance when closing the doors?

[::CMS::]

In continuation to the DIY sound proofing, I got the following items from eBay.com

EPDM rubber strips, comes with 3M double sided tape

- 5Nos x 4M (20M) BigD strip : 2199/-
- 1Nos x 4M SmallD strip : 393/-
- 1Nos x 4M ZType strip : 472/-
- 1Nos x 4M PType strip : 678/-
Total : 3742/-.

Imp: The surface should be cleaned thoroughly with a good de-greaser, I used Meguiar's APC and dried before applying.

Results : Transformed to a new car, could reduce the road noise, tyre noise or rumbling sound and other external noise to a great extend (almost nil). I need to test the wind noise on a long drive, however in city I dint notice any.The only sound I can hear is the engine note and the mirror vibration (need to change). Surprised to notice more sound from inside the car.
Really like the solid thud sound while closing the door (damped).


Pending : Engine Bay and hatch door and all doors hinge adjustment to accommodate the extra rubber.

Following are the WIP pictures:

ZType strip

BigD and PType at the bottom. All doors have PType at the bottom.

Hi CMS

I have done a cheaper solution which is quite effective as of now. I bought cushioned tape from Daiso Dubai. 5m roll costed about 100 INR. This is typically used in househould to seal windows. Worked well to insulate from 90% of the wind noise.

Will keep you folks posted on the longevity.

Hi pahwa, this sounds interesting. Could you please share a few pics? The tape seems quite thick and I thought it will interfere with door and window operation.

Thanks

Its a DIY IVI based on android dev board developed by me. So you wont get it outside.

hi C:M:S , I love the way you have accessorized your car. I am looking forward to buy a dashcam and came to know about SJ5000 which is costing around Rs.6000.

I would like to know how effective the dash cam is as compared to other mirror+dashcam products available in aliexpress, where the dashcam is integrated with the mirror and has a provision to connect the rear parking camera.
