I think it would be cool if I could program the f55 switch to control the exhaust!! Anyone have any luck with this??

studiovette

You mean work work as both the f55 and also open and close flaps?

MikeyTX

That would take a multi-position rotary switch which in itself would be an electrical nightmare.

forg0tmypen

It's got to be possible! What is a multi position rotary switch?

jschindler

It's likely pretty easily done with a relay. You just have to find a wire that flows current in only one of the positions from the F55 dial. Use a relay that "opens" a circuit when it has power to it. Use that in line with a wire that runs to one side of the fuse for the NPP...well, you get the idea.

I have the same question - do you have F55 (I don't think you do). If not, I assume you are thinking of buying the dial just for that purpose. If someone wants to donate a dial and send it to me, I'll figure out how to wire it. Or someone with a schematic of the electrical system of the car can figure it out.

One caveat - todays electronics in cars often work in funny ways because most of them deal in "signals" sent to the BCM - but I still think it's likely doable.

Your question is confusing, to say the least. The F55 switch has just two positions. How would you want to assign "Sport" / "Touring" and exhaust open / closed to those two positions?

MikeyTX

That's why I suggested a rotary switch. O/p would still have to go through the positions to use it.

Sorry for the confsion. I don't have f55 on my car so the sport and tour mode are both available to be programed. This has to happen because I just bought a new console and f55 switch. I want to make it functional, it's got to be possible.

Jschindler: if I can't figure it out here, and you are confident you can wire it up correctly, I'll send it to you I already bought it off eBay for $55.

It's labeled correctly: "sport" mode is exhaust flaps open, "tour" mode is exhaust flaps closed for those long touring hwy trips! It's perfect! Lol

Sunset Orange Creations offers their DASH exhaust controller which has a single wire into your reset switch on the dash. I suspect you could wire it to any switch you want. Give them a call. Could be that simple. I have one and it works great.

Just find someone who knows how to use and ohm meter and understands basic electricity - or do a little googling to figure out how to use it. Heck, if I can do it just about anyone can. All you are trying to do is find two wires that have continuity ONLY when the **** is turned to the touring mode and not the sport mode.

I'm not sure when I'll have time - but I can write up a crude wiring diagram for the rest of the circuit to control the exhaust. I wired mine myself without using the M2W or anything like that. Just bought a switch and figured out how to accomplish the same thing.

forg0tmypen

Oh that's fine Jim. I've wired my own m2w switch before, I guess my query was: can I use the F55 switch for this purpose? I'd also like it to light up too if possible lol

jschindler

I'd like to have a switch to play with. Maybe if I can find one cheap I'll buy one and figure it out. Let me know if you have a link to one I can buy. Heck, I'll try to make one for my car too if it's not too expensive to risk it not working for some reason. With today's electronics I just can't be sure what goes on in the switch.

The other thing is I guess you'd really need the new console piece to mount the switch properly. Might get a little pricing for my blood.

Once you have a method for switchable power to the exhaust fuse you just will need to wire it's control to the console F55 switch.

The F55 switch is just like any other switch.

The terminal connections are as follows:

P1 NC
P2 NC
P3 NC
P4 NC
P5 12V power for the lamps on the switch
P6 Ground for the lamps
P7 Turns on Tour mode
P8 NC
P9 NC
P10 Turns on Sport mode
P11 NC
P12 B+

You will need to get your signal from pin 12 and on to either pin 7 (if you want your exhaust to operate with the switch on tour mode) or pin 10 (if you want your exhaust to operate with the switch on sport mode).

If you want your lights on the switch to light up with the dash lights for example, you will need to get light power to the lamps via pin 5 and grounded via pin 6.

studiovette

Whatever he said.

jschindler

Paul, thanks for doing the homework on that.

To clarify my earlier post, I don't know what current the F55 controller can handle, so I'd use power from it to control a relay. Also, don't forget that you are trying to interrupt power for the exhaust to open, not add power. So you need to use a relay that when it sees current it opens the circuit.

Do you agree with me on this Paul? It's been three years since I've wired mine and I don't want to miss state it.

MikeyTX

This should be a slam dunk as the o/p doesn't actually have the F55 option on his (her ?) car. The objective is simply to use the F55 button in the console that was bought second hand to provide an on off function for the solenoid controlling the NPP.

talon90

In the case of the switch, the B+ line to pin 12 is fused at 25 amps and the switch operates in a 12v circuit from the BCM. The way I'd go about this is to start as if you were following one of the DIY threads to add your own mechanical switch to control the exhaust and instead of wiring in the actual switch, wire it to the terminals on the F55 switch so that when it was intended to be closed you would bridge which ever two terminals you wanted as l listed above and when you wanted it to be open, just wire one side to one of the NC connections as listed above which aren't used in the operation of the F55 switch.

jschindler

Thanks Paul.

Guys I need this in English!! That's good that it's possible. When I get the switch, I'll look at the pin connectors and that might make things make more sense to me.

As for making the lights work, I just need to provide power by tapping into pins 5 and 6?
