Installation manual for the extended sports-exhaust flap-control-system made by insidePerformance for BMW M5 and M6 (F10 / F12 / F13).
This flap-control-unit (FCU) allows you to control (open and close) the exhaust flaps whenever you want. This can be done my using the OEM M1-button on the steering wheel (on all M-Models).
That works idependant from your selection and configuration within the M-Menu (iDrive).
On non-M-models, the flaps are opened when driving in SPORT or SPORT+ driving-mode.
This FCU works with all flap controlled exhausts - independant of the manuvacturer / vendor / brand: it works with the original OEM exhaust system, the BMW Performance exhaust system, Akrapovic exhausts and all others. And of course with the
insidePerformance BMW M5 flap controlled Sports-Exhaust.
Even on cold-startup of the engine, the flaps can me opened.
A detailed product description and product ordering can be found
here.
Example video X6M:
First the trunk-floor has to be removed (2 nuts):
Then the platic part at the trunk border must be removed. This part is attached with some expanding rivets on the inner side.
There might be a 12V plug in this part - just jemove the plug bevore you remove the whole part (M5).
On M6 or M6 Convertible there might be 2 more silver plugs that are screwed. Use a tong to screw it out:
Now the lower trunk compartment can be removed:
On the left side of the trunk, remove 2 rivets and fold the paneling aside (or remove all rivets on that part, if you wish).
On M6 / Convertible there is an additional plug with a rope that has to be disconnected:
Behind that panel you will find the unit controlling the exhaust flaps by vacuum. There we will connect one harness of the insideperformance FCU later on:
Now remove / fold aside the right trunk panel by removing 3 rivets and one screw that fixes a trunk loop:
Now remove the compartment at the right side (rivets):
==================
Case A:
right above that, you will see another control unit (for the fuel pump).
[ on M6 / M6 Convertible this unit might not exist. In that case seel below Case B ]Remove the plug of this unit (press the plug-nose to remove ist):
On this plug, there are small flaps on both sides of this plug that hold / secure the inner pins in that plug. Carefully open both flaps:
===============
Case B:
If this unit does not exist, just use the following unit which is mounted in front of the battery at the cars back wall:
After opening and removing the plug you can remove the back-cover of the plug:
There is also a blue plastic part in the side of the plug that fixes all pins - remove that blue retainer.
You can remove the pins that are listed below by putting a BMW special tool (or a paperclip) into the hole next to the hole of the pin itself. There is a small spring that need to be pushed down trough that hole so the pin can be removed. That is a bit tricky - if you feel unconfortable with that, ask a specialist - they have special tools for that!
===============
Now 3 pins of this plug have to be removed and replaced by the pins attached to the insideperformance FCU.
===============
Case A:
M5 / Fuel pum unit:
Pin 9 (blue-red wire)
Pin 16 (red wire)
Pin 13 (green-red wire)
the numper of the first an last pin in each row are written at the plug. Just count the pins to figure out the numers in between. Pin 9 and pin 16 should be the last in each row. Pin 13 is 4 pins before pin 16.
To remove the pins, a small spring at the side of each pin has to be pressed through a small opening at the side of the blug. Best is to use a paperclip to press it down while pulling the pin out.
===============
Case B:
M6 / Convertible - Unit in front of the battery:
Pin 12 (blue-red wire) - CanBus
Pin 13 (red wire) - CanBus
Pin 1 (green-red wire) - WakeUp
the number of the first an last pin in each row are written at the plug. Just count the pins to figure out the numers in between.
===============
Make sure to put the new pins (with the same wire color) of the FCU deep into the plug! Compare the pin position with other pins in the plug to make sure they are latched correctly.
Indepentant of Case A or Case B (plugs might look different), the mentioned Pins have to be replaces by the Pins of the FlapControlUnit - each Pin with the Pin of the same wire color:
The removed pins must be interted into the supplied green small plug and the side-plap of that plug has to be closed after all pins are inserted.
The pins have to be inserted in that way, that the wire-color matched the opposide wire-color of the other matching plug at the FCU harness:
At the right trunk corner the lug of the black FCU ground cable has to be screwed to one of the existing ground cable points at the trunk wall:
on the left wall the flug of the existing vacuum control unit has to be removed by pressing the buckle. The removed plug is connected to the matching plug at the FCU harness. And the other plug of the FCU harness is plugged into the vacuum unit. So we create a kind of Y-connection:
Nof the main FCU module can be attached somewhere - i.e. at the right wall next to (and in front of) the battery. Use the supplied glue pad. Clean both sides before you attache the glue pad.
Be carefull to leave enough room so the trunk compartment still fits in. Attach all FCU harnesses somewhere - best at existing oem harnesses. Use the supplied laces:
Now we are ready! Plug the fuel-contol-unit plug back into the unit and start to test if everything works.
If everything is fine, assemble all parts back into the trunk as you have removed them.
The flap now ALLWAYS opens, if you press the M1 button on the steering wheel and if the M1 symbol is shown at the dashboard.
If the M1 button is not active, flaps should be closed. There are some exeptions, where the flaps still can be opened - these exeptions are coursed by the engine ECU and are for engine protection. So we do not overwrite these protection settings. That might be the case after a hard drive if the engine is hot - than the engine ECU might want the flaps to be opened for cooling (independant of your selection). Or if RPM rises above about 4000RPM - that the flaps are are also opened independant of your selection.
