Experience with ASR CB2 Valve Controller?
#1
![Default](/forum/images/icons/icon1.gif)
Hello,
Does anyone have experience with the ASR CB2 exhaust valve control unit?
If you do, did you have any issues? does it work seamlessly through the Jag's active exhaust button and driving profiles as advertised?
https://asr-component.de/gb/flap-con...ntrol-cb2.html
I will be picking up my new 2024 F Type R in few weeks and am shopping for some little improvements to really get an R-rated experience from get go.
One of the first items on my list is to get exhaust to sound like its meant to be at all rpm's.
However, I would like to have that glorious exhaust on demand (can switch to quiet) and in a neat package, preferably one that is integrated with already available Jag controls.
I want it all, and i am willing to pay a significantly higher price (~600$) then with other known solutions if this unit really works.
Especially if the same controller unit also remembers to automatically disable pesky start/stop!
PS.
I am aware of the following other solutions:
- "permanently open valve" solution like pull a fuse
- "remote relay with fob controller" like the clever "claws out mod" and cc charger
Thanks you!

Got the controller ordered since it works well for main purpose: control valves.
Strange that you mention it doesn't disable Start-Stop for you. The guy in a video on ASR website shows controller automatically turning start-stop off upon start of the car (memory function).Anyway, will share the results on my once I receive and install it.

Mate, no need to worry, it's only for the V8 and even then only the late model P450 and R, us measly V6 owners can continue to bask in ignorance.

On the linked web page they say:
To me this means that whatever setting the start-stop system was in when you last ran the car, ie either on or off, is retained when you next start the car up.
Rather than the annoying stock system where the car defaults to "SS on" every time you start it.
Which means that once you turn the SS off it stays off indefinitely unless or until you hit the button to turn it back on, sounds like a good system to me!
Of course this is irrelevant to me as this system is available only for the late/current model V8 and I have an older V6, and I have permanently disabled the SS system anyway!

Yes, possible to disengage start/stop through wiring disconnections. Though I would not let children play with the wiring on my jag
![Smile](https://www.jaguarforums.com/forum/images/smilies/smile.gif)
On older F-type vehicles can disconnect a secondary battery and then your battery management system doesn't know what state it is, which leads to it disabling start/stop.
On new F type new vehicles can disconnect electric plug from voltage module to disable start/stop. I believe this action sets off a fault code. Though you wont see a fault code but your dealer will see it, maybe even attempt to repair it....
The above options are functional and do disable start/stop. However, they don't appeal to me due to my engineering background, I do not want to disconnect any modules on the car if at all possible.
Would rather have a logic control unit installed that allows to disable a start stop function until further notice - something i believe the ASR unit does based on the advertised "memory" function.
By the way, many other brands have such functionality added and designed in by default. Jag doesn't for some reason, guess trying to keep our memory or electrician skills sharp.
Anyway, I understand my approach is preference-based that will cost me the 600euro (hopefully not more) and may not be what others preffer. I am ok with that

The new F Type have rev limit on when valves open, at above 3500 rpm. Pressing the active exhaust button doesnt help, at below 3500 rpm valves dont open

The European regulations on noise led to this outcome.

Yes, 6 month in and its a success, am very happy with it.
The exhaust button works as it should, can open the exhaust at any rpm and don't have to be in sports mode.
The autostart is defeated and not coming back each time I start the car, don't have to remember to press that A button.
Installation was relatively easy.
You do need to get out the bottom and side trunk cover panels in order to get to the wire harness and crimp splice the controller in.
Took me probably couple hours and most of that me being extra careful and gentle with detaching/reattaching cover panels in the trunk of my brand new jag.

Good job! I will get this ASR module myself then. The only thing I'm not clear or concerned is forgetting the valves are closed and stepping on the gas. That's because the F-Type manual warns the valves should not be closed under hard acceleration because "things" can get damaged. Something like that if I remember correctly. How does ASR module work? Is it possible to keep the valves closed throughout the rev range and risk the damage? Or is there a safety programmed in that will force open the valves over 3500 rpm no matter what button/mode is selected by the user?
EDIT: It's the ASR website itself that warns that the valves shouldn't be closed under acceleration:
"When driving at full throttle, the flaps should not be completely closed"

That is the exhaust valves are closed at rpm below 3500 and automatically open at above 3500+ rpm.

so there is safety built in after all... wonder why did ASR put out this warning then...

And did you give it full throttle with valves closed, did you notice anything strange?

I got a small handheld transmitter that looks like a garage door opener with 3 buttons. I've never given full throttle when I've manually closed the flaps. I either drive this part in OEM mode, or generally open the flaps! I also have the feeling that the system is louder in open mode than in OEM open mode! I can't explain it, but that's what it sounds like.
