lets be responsible guys.
Lots of performance type cars do it right out of the factory. My mini Cooper pops and burbles all the time....on a factory tune. It's not going to hurt anything.

I like the sound....as long as it's pretty mild and burbly. I don't like the crazy loud pops and bangs.....those loud shotgun blasts probably aren't good for the turbos or anything else. But....to each their own.

Please tell all the douchebags with Hondas that live down the street from me.

Burble tunes and gunshot tunes can all die in a fire.

Don't really need more burbles driving around but I want to be able to hear it in park.
You can set it up to have no burbles when in drive, but have burbles when in sport mode and neautral/park. That's how I have mine set up.
If I wanted burbles only in park can I set the sport mode to 0s and the car will behave as if the burbles aren't on? My car gets super hot when I run burbles so I'd rather just have it on when I want to rev it

Yes....pretty sure you can set the duration to 0s and still get burble in neutral.

Why would your car run super hot with the burble activated? Doesn't make any sense.

My car is an 07 and doesn't have an oil cooler and also I'm assuming since it's pumping unburnt fuel into the exhaust manifold to explode it might aid in heating things up. Car doesn't feel right with hard burbles on either. Drone gets a lot worse (I have cutouts)

Mines an 07, no oil code either. I don't have any issues at all. How long do you have the duration set for? I have it on the agressive setting...0.0s during in drive, 0.5s in sport. In sport mode I might get just a little mild pop or two...and that's it. I used to have the duration on 1.5s...and it was annoying. Still not sure why it would make the motor run hot......if anything it might cool the cylinders down since it's dumping all that fuel into them (rich).

You can.

I have burbles disabled in non-sport and burbles set to 0.5s (hard) in sport mode.

Even with burbles disabled, there is a SLIGHT pop on decel. I am assuming its just the stock tune. I'm sure its harder to hear if you have cats or secondary cats. My car is straight pipe.

I have it on 0 for d and 0.1 for m and I consistently hit 255. Installing oil cooler soon which will hopefully fix problem

Still trying to figure out how injecting a little extra fuel into the engine when it's under zero load would ever significantly increase your oil temp. Doesn't make sense at all.

I have no oil cooler....i haven't notice any difference in temp with or without burble tune.

Why don't you use the MHD Coolant target flash? At least for the time being keep it on sport coolant mode.

Didn't see that was even an option. Thank you I'll try it out and report back later

There's a different fuel cut delay based on a speed threshold, if anyone on a custom tune wants to use it I can post the directions.
id be keen on the direction for doing myself via custom map.
and the XDF you refer to also if you didnt mind
