Bubble Tune

[porschedude996]

Wow! My house has a street on the backside which was opened through to connect the north to the south of town. It has a speed limit of 40 mph, but the reality is 55-60-90mph. The traffic has increased in speed and noise far beyond what I would call tolerant. The worst times are the retail rush hour. So get up 15 minutes earlier and drive at a respectable speed. Add it the STUPID BUBBLE TUNE! WTF are these idiots thinking? Somehow they think this sounds like a F1 race car? I guess I was blessed with cars of the 60’s and 70’s. Horsepower is horsepower, Fart-Cans and Bubble Tunes are fake BS.

it's not bubbles...it's burbles.
I belong to the Civic SI forum and hear it mentioned frequently.

I was going to say, "what the hell is bubble tune?"

But that makes sense, burble.

The funny thing is that burbles are natural with a carbed motor. Then modern FI came along, and engineers realized that they could increase efficiency but cutting fuel flow when a car is coasting, so they implemented that.

But folks hear race cars burbling, and want their cars to sound cool like that, so they are pumping fuel into the motor when coasting.

So it's intentional inefficiency for aural aesthetics. It does sound cool, but I wouldn't turn it on unless there was some sort of actual performance reason for it.

BMW pulls away from the morning coffee shop, slowly changes gears at about 15mph and.... Lordy.

If I run my Civic SI up to almost redline and release the throttle....it burbles.

It has to be in sport mode or it won't burble.

Just another way those BMW fools are annoying.

I think Honda put the burble back in yours since it's so desired, but only in sport mode.

Years ago, I discovered that I could get a tiny bit of burble by coasting with the foot barely on the gas. I don't ever do it, but it was interesting to discover.

Did I miss something about how/why "BMW" entered this thread?

Most modern day fart-can cars with burbles would blow the 60-70's car off the road...while getting 30-40 mpg.
But I do appreciate the older cars. My first car was a 66 Chevelle...loud and fun. 15mpg and it rusted out at 100K miles.

Cars tuned in this manner are specifically banned form my area's oldest and largest weekly cars'n'coffee. The volunteer staff that assists with parking and lining up all of the cars (affectionately known as the "thugs") simply turn them away, not even allowing them into the parking lot.

My Duc used to burble due to an inherent lean condition. It was a cool sound but I tuned it to eliminate the downshift snap crackle and pop. Even my Harley runs quietly.

So back to Bosch CIS.

Yes.....I want one.....Coupe, dark silver/gunmetal w/ tan/cocoa interior please.

Honda, BMW, and the odd loud truck. They are the most common near me.

My favorite is the Harley with super-loud open headers, and then the radio is cranked up for the rider. And anyone within 500 feet.

Lots of inconsiderate twaatz out there.

My son got pulled over and 'warned' for a missing muffler (he had an appointment to get it fixed, so they did not ticket him), but these cars are way worse...

I asked a local cop why they never ticket the loud motorcycles, he said 'I have no idea what's legal and what's not'.

A couple years back, I was headed home from the airport around 2am. Almost nobody on the road and I'm doing 85-90 in my Prelude with a Greddy exhaust.
I spotted the cruiser sitting in the median and let off on the gas. He lit up and chased me down.

I lowered the window and said "What's the problem Sir?" He answered "When you saw me and let off on the gas...it sounded like a truck with a jake brake."

We talked for a few minutes and he ended up saying..."see if you can find a quieter muffler"
no ticket.

I still have that one on...it only does the loud noise when lifting from high revs.

Saw a guy on the freeway the other day with a burble tune. He would hit it, then coast, then hit it, then coast...Aarrgghh! So annoying.

Does it sound any worse than when they hit the rev limiter and stay on it?
