I assume these controllers will not void warranty right?

I've been really considering the fuse based golf tee mod but remembered how embarassed my wife was when dropping our kid off at the Montessori in my car. I switched it to all to comfort and turned of M sound and instantly, she felt better. I might hold off on this for now

Today I did the fuse pull trick, that keeps the flaps 80% open in any driving mode. No error codes, and the sound is perfect.
After driving around a bit, I then did the mod where you open it 100% and keep it in place with a wire. Honestly cant hear a difference. If anyone else want to do this, rather just pull the fuse. Must say, with the wire mod done, I now have a wooshing sound from the turbos that sounds cool. I think those valves move constantly when stock standard, depending on throttle position. It will open and close as you drive even in Sport+ mode. That is my take on it. |

I recently began offering this product as an option for opening the exhaust flaps. It provides a way to get the additional sound from opening the exhaust flaps and does not require any cutting/modification to the electrical or exhaust system. It’s completely removable/reversible in case you decide to return the OEM functionality. I am a forum sponsor and recently posted an intro in the sponsor classifieds.

Supposedly the valves are only 80% open when controlled by the car so if you open them and pull the fuse they'll stay 80% open. If you physically open them you can open them 100%.

if you want the valves to always be open, doing it manually makes the most sense. Cold start with the valves open might be too loud for many, also daily driving as not everyone prefers driving with the maximum volume all the time. This is why controllers like the SST are so popular, offering the flexibility of opening and closing the vales, + fully opening the valves to 100%, compared to the 70% offered by the default settings.

I have valves open at all times. I had my tuner turn off the cold start as it was extremely loud (even with valves closed), and was setting off car alarms in the parking garage at my work. With the tune highflow Evolution downpipes and Valvetroniccatback, the natural burbles and pops with valves open can be reeeeally loud, especially at higher rpms. I wouldn't want to hear it with catless downpipes. |

Looked at my exhaust flaps after pulling the fuse. The driver's side appears to be open 100% (or close to, can't see any of the flap), but the passenger side is only open about 15-20%. Is that normal? I closed them, re-opened them several times with the same result.

Anyone have experience with the AWRON CAN BMW flap control PnP on G87. No need to cut and solder wires and keeps functionality of all OEM valve control switches. Open and close the exhaust flap at any time. One press of the exhaust valve button and the flap is operated independently of the sports mode.
Looking for a writeup on the install on M2 if anyone has done this. I have seen install on M3...wondering if similar. |

Got my AA equal length installed yesterday. I was surprised how loud cold start was even with the valves closed this morning. Now I’m scared my neighbors will murder me if I add an axle back lol. No way I could get away with disabling the valves to stay open.

I find it still pretty quiet other than the slight valve rattle when they're closed during cold start with the AA EL. Pop them open and it's a different story. But I am also coming from a v8 Mustang with long tubes and full exhaust so maybe it's just relative. I always park backed in and start with the garage door shut from when I had that car which helped some so with the g87 there is 0 worry doing the same.

Is there a controller that works like stock but just opens to 100% in M1/2? I like having the valves. I find a wireless controller kind of janky and want it to be closed always on startup unless I hit M1/2, but I figured someone had to have come up with some type of in-the-middle override module thingy?

https://g80.bimmerpost.com/forums/sh....php?t=1991762 I use the SST as well. It’s exactly what he doesn’t want because of the remote. And I understand him. If the AWRON was cheaper, it’s what I would’ve gone with. But these flap controllers don’t make much sense at a higher price given the little difference they make. |

So after watching some videos, seems like it really functions the same as the SST just uses the exhaust button on the center console - seems like going with the garage button would be cheaper and not much different.
Just talking out my A$$ but I'm familiar with controls for HVAC and such, lot of our actuators use a 0-10v ... 0 being closed for example and 5 being fully open. I figured maybe the signal to the valves is the same.. So if sport is 4 or sport+ is 7 it would just take that 4 or 7 and have it a 10... that way you get 100% open while still maintaining comfort mode and without hitting any extra buttons.

Awron specializes in CAN/LIN technology, as their main focus is data acquisition and controls modules/harnesses/displays for BMW racing engine swaps. Awron operates as a gateway device for the controller, intercepting commands, taking into effect engine parameters, and outputting a custom command/operation. EVC signals are intercepted and are controlled via factory CAN commands with additional safeties programmed in place to prevent issues (like valves not opening at all) from happening when you are using a 3rd party controller. The vehicle still does the work, still monitors, and still error checks if something is wrong. Circuit boards are professionally made in house (they have their own pick & place machine) and harnesses are professionally built with BMW/AMP connectors and harnesses matching factory wiring. You couldn't get a better kit if it wasn't offered by BMW themselves, which is a bit ironic to say as Awron was contracted to build the information displays for Alpina. For Awron engineers, an EVC controller is a walk in the park in the overall scope for their daily tasks.
