curious to hear more about people with MPE and LCI..
i have a 2016 but have the newest DME update and i just got the MPE installed this week... i DONT HAVE ANY pops or bangs, i tried reving to 4500-4800 in 2nd gear and letting off and get nothing, i was previously having issues with my car so i am not sure if the no pops are due to past issues or is it just the new programming? i do hear some burbles at times but it is barely noticable can someone with MPE and LCI please confirm that they are getting pops? thanks |

I have a 16 and it sounded great, then I took it in for a software update and now they are almost gone. Pisses me off. My car used to sound great now not so much. I have a HFC and res delete with stock muffler.

my initial thought was that my stock cat was messed up, but i see you have a high flow cat so i am 95% certain the issue is engine management related anyone else in this boat? wait until the car is warmed up ...rev to 4K in second gear and let off...if you hear a muffled choke sound welcome to the club |

Ooof, that's the one to avoid then. I'm On F020-17-07-504. Did you make sure car is warm, and you wait to drive a bit regularly before switching onto sport or sport+? Note that if the IAT's or EGT's are too high the car won't burble as much.

I have stock on my M2 LCI and its loud, plenty of pops and gargles, still has a nice tone when in comfort mode, put on sport and really comes alive. I test drove car with M-Performance exhaust, naturally illegal to use here on roads here in the UK. When i fire it up on the morning my missus can hear the car from the underground garage and can hear me when I pull in as well so no complaints from me.

i just checked and my dealer says they gave me the F020-17-07-504 update, which is the same as the others who don't have the same issue so it looks like our problem is something else

Yes me, as I've written before my early my'17 EU spec makes less pops and bangs after the update with the latest ISTEP version. But it runs better now.

Wish I heard a pre lci model... My LCI does all the burbles when letting off, but I've never heard loud pops and bangs. MDM mode is the loudest /most sounds. Sport /sport+ has a little but can barely hear it with windows up

when functioning properly my 2016 had nice burbles but not loud pops and bangs.. i think that would be more for people with an aftermarket downpipe or exhaust
