Looking like it will be a flash-time option in MHD

Jake, for those of us wanting a more aggressive burbble / gurggle than the option that will be provided by you via mhd, could a custom tuner fill the gaps?

I am going to talk with Martial on how to best implement this in MHD. If the flash-time option is not aggressive enough for you, I can custom tune it and make it as crazy as you like.

I have sent a map to a friend with a loud exhaust and go-pro, once it stops raining he will have a great video I will share.

Is it messing with a table that affects performance jyamona ? So it could be a trade off for a little more cool exhaust noises for a few less trq/hp?

Will people on stock downpipes and exhaust still get the sound or is it strictly for catless dps?

No, it will not hinder performance. These are OFF THROTTLE noises we all seek Watch jaguar F type videos of it's exhaust.

Yes, but will not be as loud. See N55 ppk videos.

I'd be happy with n55 ppk sound although I think it will be less on the n54 since it has 4 cats and resonator (pre-Lci e90)

Maybe we could have a slider option under MHD settings, similar to the rattle-fix but only named exhaust-fix with varying degrees of burbles

That is a good idea. Some might want more or less depending on their exhaust configuration.

Curious to see when this will be implemented in the next update. Any set ETA you can give us? Can't wait to try this out.

I think what also adds to the allure of the jag is that cracking sound ON throttle. Reminds me of the NA amg cars.

Not sure if fuel cutoff can do that or if it's just a v8 thing.

Admittedly I get a lot of "gurgle" and sometimes pops while off throttle with FUD98 (jb4 rattle alternative). What we all want is that thunderous cracking sound

That would be epic. MHD Tuning I just wonder if Marshall would have to set it up in a way as a numeric value rather than a slider. I figured this might be awhile before we see it in MHD since I think he's been working on getting anti-lag into MHD, start up needle sweep, etc... Things JB4 can do that MHD can't yet.

Good luck. I've sent Jake an email at motive about tuning my car. I want to see what his price is compared to Ken. I haven't heard back from Jake yet. I think he's a pretty busy dude.

Would this be separate from the JB4 BEFs? Or could it be incorporate when we flash the BEF?

Martial will implement it in MHD however I advise is best. This has yet to be determined.

Flash-time options can be added on top of JB4 BEF, so you are good.

Yes, Wastegate fully open at 0-x% throttle

It's the only thing that got rid of my downshift rattle

Getting excited for this option however am curious as to what would be the trade off would be for ticking this option.

All I can think of is slightly increase fuel consumption and possibly more wear on the injectors?

for sure you would have to dump fuel for the pops...

i think it's changing the fuel cut delay during overrun and ignition timing?

might affect engine braking?
