You should start to pray that your soundproofing setting will not affecting the car ECU

The stock car had a pre-program system (ECU) to monitor the driving behavior and adjusted the system as and when appropriate. If added soundproofing which interrupted the original setting, the car will not cope with the system and ultimately this FC issue might be happen. Since you all have money to add the soundproofing, why not just upgrade a turbo kit to make it a true racing car. Honda ECU already open the setting for you to proceed with engine modification.

PS: your information are being recorded nicely

That guy is pulling my leg about ECU.. lol~
I did sound proofing for a quite ride

FC? Nope. Not at all.. if you scared then lose some body weight.. good for health too =)

but it did somunds heavier and more rough for me. used for half a year now

Think everyone has this bumper dropping issue, creating a gap between bumper n body. Looks worse than my 10 year old car. Ignoring it since bumper not flying off. Many went to SC and seems there's no solution from them. Bad design bumper clip design, i guess.
