No key fob needed or supplied with the module I got, ASR CB2.
Valves are operated through the factory original exhaust valve button on the console.
I can hear the valve open up as they should at high rpm when exhaust valve button on the console isn't activated.

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?

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!

I think, in the stock mode, the valves do not open 100% in the dynamic mode, sometimes 50 or 75%, perhaps under fullpower 90%, but when you use the mode with RX1 "open", the valves are all times 100% open :-)it is louder as the OEM Mode Dynamic :-)
that is what I can say after installing the RX1 !

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.

There is a safety on the CB2 which doesn’t have a remote, it overrides your exhaust button. So you can have it quiet or valves open by pressing the button. The RX1 comes with a remote. You can have the quiet (stock) version, press your factory exhaust button and get some more noise or turn press the button and turn the ASR module on to have 100% open valves. The RX1 doesn’t come with the built in safety if you close the valves, you have full control. CB2 is never closed, it’s stock or 100% open, no ability to close.

Definitely looks intriguing if it works, but the Claws Out mod (especially if you program a Homelink button to activate) combined with the active exhaust button and standard/dynamic mode button gives you every possible combination this box could give you, for less than $30 US.
