I was wondering why I didn't get any pop and burble from my tune... I never asked lol

I figured it was because i still had both my cat's

Does it use any extra fuel when you add that in?

 

Yes, my custom tune has it, and I love it.

There are many incarnations of the tune though, and from what it sounds like not everyone has it. There is a specific piece of mapping from the JCW Challenge car which allows for the burble. It does nothing for performance, but sounds GREAT.

From what I've seen, by watching AFR's, it merely keeps the injectors open a for a split second longer after throttle lift off. Will not have a noticeable effect on MPG

 

How about a few vids of the pop and burble....

I'm very interested to hear what all the fuss is about so I can determine if it's something I want included with my tune.

 

Mine doesnt have pop OR burble...but I did ask for it...did it just forget to be included in the tune Jan?

 

I think only the JCW exhaust gives the pop and burble. With Jans tune that is, because I dont have it either

 

I'm pretty sure the pop and burble is in the tune. My MCS has the JCW exhaust and has no burble.

 

Hmm, do you only have one cat? like the factory JCW?

Does anyone with a MCS have the pop and burble?

 

+1 p&b?

 

I still have the front cat; thinking of deleting that and putting in a larger resonator (think hacked up custom version of JCW factory front muffler).

 

So after nearly a year w/ Jan's tune (& more recently the updated tune), I just put the 'stock' map back on for a dealer visit... I could not live w/ my Mini like this... I'd grown accustomed to the increased throttle response, the extra growl from the exhaust, the torque steer, it's all gone. Once the other issues are sorted out at the dealer, I'll be putting the tune back on, and having Jan add the pop & burble next, will certainly be the cherry on top.
For anyone running the 'old' (last summers) tune, the updated version adds a lot of polish.

I did notice some torque related faults in the stability control system, eg. PT_CAN_TORQUE D365, D366, & D367 and a couple shadow faults in the ECM 2D52 & 2DCB (these were pulled with the Bavarian Tech tool, not a regular code reader which showed nothing).

 

Jan told me that he didn't add the pop and burble to the version he sent to the group buy just to make sure everything went okay with the basic tune. Sounds like he will be adding it soon along with some other upgrades.

 

I also did not get the bov flutter as some mentioned that is now there.

 

The BOV flutter is only on factory JCWs. It comes from the MINI Challenge car maps.

 

Jan sent me a test tune with it for my S, but the car went into limp mode after it was installed. Still waiting for an updated tune.

 

Posted it before in a couple places...

Here's mine...its not from a true video camera, so good set of speakers will help it sound more accurate

 

Wow that sounds awesome

 

Any other reason for the pop burble besides the sound? Why did mini put that in the challange series?

 

In rally racing it is/was common to inject fuel directly into the turbine housing to keep the turbo spooled up at low throttle. The fuel ignites, creates heat and keeps it spinning fast at low rpms. It works great...instant boost at all times. The sound is awesome. It also eats up turbine blades so fast the turbo is toast by the end of the race, that is if the engineers got it just right. This is not what we are getting but the sound is similar without harm to the turbine blades.

 

Can someone post a video/audio of what the BOV flutter sounds like?

 

Mini didn't add it to the Challenge series, it's just amplified due to the larger/open'r exhaust. It was only removed from the North American R56 MCS to placate some old ladies that complained about the noise (on the late R53's), rest of the world still has it from the factory. It's a classic british 4cyl sound, harking back to the days of carburetors.

 

Posted elsewhere on NAM but here ya go... enjoy.

 

Mine does not have the flutter....

I really can't help but say.....it sounds like compressor surge....

 

I hear it in other turbo cars all the time. The noise isn't always a smooth sound. So if other bov's are any indication, its normal?

 

Makes sense. Old ladies wrecking havoc on our mini enjoyment .
