    Hi everyone,

    I just got my 488 spider and I really love it ! BUT :

    I like LOUD cars !!! ... I noticed that the valve open at 3/3,5 rpm in sport mode (i live in Paris so race mode is not the way to go everyday with the ****ty weather... even in race mode is not that good as the gearbox hurry to be at 7th gear) and after forum diggin I found that there are many mods to open/close the valve on demande despite the rpm/speed.

    Did some of you try this mods ? Are they safe for the car engine (no engine warnings led) ? There is a noticeable difference in sound at low rpm (specially in sport mode) ? Which one do you advice (forza, Capristo...) ?

    Thank you so much for your help

    I'm using the Forza B2A. The valve open mode can be handy when driving around slow if you want that extra noise. I had my dealer install mine - no big deal they said. The head Tech also said there was no harm to the engine or warranty using the controller however did say that the engine would perform at its best in the stock mode during sporty driving. Sport mode is where I mostly leave mine although depending on road surface I will use the bumpy road shock setting in sport mode.
    I found the service and advice from Steve excellent and would highly recommend. steve.bisel@forzacomponenti.com

    Agree-have used Steve's unit on my 458 Aperta, F12 and F12TDF. Have just ordered again for my 812 and is being installed next week. Very reliable, easily installed and would not even think of having a F car without this.

    You've got a nice line up of F cars going on there carlom001! And agree a Forza unit is the best way to solve any noise issues without screwing up the cars warranty.

    Depends on the dealer. My local dealer absolutely will not install a valve controller. Furthermore, they told me that they will void the warranty if a controller gets installed. Bummer as I would love to be able to control the valves.
    It seems that dealers have different views so, if the car still under warranty, it might be a good idea to check with your local guys before proceeding.

    I also had Steve’s Forza unit installed in my 488 by my dealer. He recommended it to me so no warranty issues here.
    Highly recommended

    Thank you All for your replies.

    So i guess the Forza Model B2 is the way to go...

    My dealer tell me that in some case installing this kind of module can light up the Engine warning led in the car dashboard ?! Did some of you experience this issue or do i need to do something during the module installation to avoid this issue ?

    thx

    I contacted Steve and he was very helpful answering my questions.

    About engine fault question, Steve said “ The controller module has a circuit inside it that emulates a closed circuit when in fact you have opened the circuit to make the valves go to open condition. This emulation circuit makes the car’s ECU believe that the circuit is complete to avoid the engine fault light.‘


    I just have one specific 488 question, where do you secure the module (from the heat...) ? Do you have it installed in an accessible place (let’s say to pair another remote controller by your self to avoid going back to the dealer)? Can you send picture of the module placement please ?

    Thank you

    Dealer opted to mount on left hand side behind the rear behind wheel. They had fitted these units before to other customers cars and felt that was the better position away from any heat. The rear bumper was also removed at that stage to install the My-Ricambi carbon tail light satellites but may not require removal for the unit.

    As shown in pics the inner splash guards were removed and the unit affixed to the rear of the wheel-well accordingly. I recall buying the longer cable although you will see a section of cable bunched up and cable tied off onto the unit so I'm not sure if the short cable would be long enough. Steve may be of more help there.

    Does this throw an engine fault if you unplug these?
