GTS valve controller

2 Ferrari dealers said they would not fit one, even though they did my superfast and F12.
They said it was not compatible with the GPF on the GTS.

 

My Ferrari dealer refused to fit Forza but they were fine with installing the Capristo one

 

Thanks for the heads up, appreciate it.

 

My 812GTS hasn't arrived but I talked to service in advance and they said the same thing. They did say they had the Capristo in stock so perhaps that was the reason

 

Does your car have GPF?

 

That must be it. Doesn’t make any sense. All,these controllers do is either pin the valves closed, pin open or leave in.normal mode. We don’t install new butterfly valves it’s purely a controller. Maybe someone much smarter here can explain why a manufacturer would make a difference, with the obvious fact that dealers sell C products and not F. Head scratcher for me

 

It's already been explained earlier in the thread. The Forza controller is potentially damaging because it's possible to close the exhaust valves at all RPM. This will create a large amount of back pressure at high RPM which is bad for the engine.

In contrast (and contrary to your statement above), the Capristo has no 'always closed' setting so this is why Capristo is safe and Forza is not.

 

… or you could just do a muffler delete and get rid of the valves and mufflers and vastly improve the sound … without new hardware or a CEL …

 

This is correct. Also all 2020+ Superfasts

 

Spoke to Capristo dealer In the UK, he said no problem, so booking in for a couple of weeks time.
How much difference does it make for those that have fitted one?

 

My bad. Thought someone recently stated they could w c. With that said, as long as you don’t do it it I should be fine. My only use is open all the time or regular. So the C has the ability to close but at a certain rpm it will override and open up?

and I m referencing a GTS so no turbos. Car has been serviced w no mention but may switch it to C to make life easier

 

Another one. Looking at their site capristo doesn’t list the controller for the GTS, just SF. Anyone know if they are interchangeable?

 

I clearly have the forza but shouldn’t matter when valves are open. It’s pretty significant. Much more bass and when slowing and downshifting you get more pops and gargles….I like it and I like to be able to turn back to stock when needed. Super easy and pretty inexpensive upgrade for what you get

 

I have installed the Forza controller on both a superfast and now on my GTS. They are exactly the same.

I am going to order the Capristo, I had it on my F12 and it worked pretty well.

 

Some USA MY2020 Superfast do not have GPF. Cant speak about other markets

From Capristo:

"Unfortunately the GTS our controller doesn’t work. The ECU constantly scans for valve position and we haven’t done a redesign on the module at this time."

 

I have the Forza controller on my 22 GTS and it works great!

Funny that Steve/Forza told me he wasn't sure if it would work.

 

Well it does work!

That’s strange! I have a capristo controller on my 812 GTS and it works perfectly fine. No ECU alerts!
