Today I took my F12 wich was parked for 2 weeks and only ran approx. 10 miles to meet a friend. Almost arrived I pressed a bit the pedal to enjoy the V12 sound and In despite the water and oil temps seemed ok at the dashboard the car didn't want to exceed 5000rpm? AT was 25°C. 1 hour after I came back home and tried again after a few miles: same result!? No cell, nothing at the dasboard. I had no time enough to run longer the car and test more. I assume it is the engine protection which doesn't allow the V12 to exceed 5000rpm until all is hot enough? By comparison I do not remember the FF needs so much time to warm. Thoughs?
Indeed, its an engine protection system. I would imagine that after 10 miles in normal ambient temps the engine would be warm enough. I'd have the dealer look at it.
That's odd. The engine should be at base running temp after 10 miles. What was the temps when you tried to rev it? It's been a while since I was in an F12, but both the Lusso and 812 revs freely after the cold start cycle has finished. Somethings off. Sent from my SM-G930F using FerrariChat.com mobile app
Thanks for input 360 and A. I do not remember where I heard/read about this 5000rpm limit until hot, so not sure... Yes that's odd, the both temps were about 70°C if I'm right. I was in race mode/manual shifting and the car was like getting in limp mode above 5krpm and shifting to the next gear in auto mode at 5k, very frustating. The car just reached 5000km and was serviced last month by Ferrari who gave it their 24 months warranty so I'm not very anxious... I ran it about 1300km in 3 days before drive it home when bought it last month, all was perfect but it had much time to warm up. Whatever the car I take I drive it gently with no load until at least 15 minutes, I love the mechanic, nevertheless I never noticed this with the FF.
Try this as it is pretty cheap to do. Get a CTek 7 Ah charger. Use the battery quick disconnect and disconnect the battery. Clamp on the CTek and let it charge overnight with the battery disconnected. This will serve two things. It will assure that the battery is fully charged. It will give the car a hard reset. Next day when the charger reads fully charged, reconnect the battery and do the battery connect procedure with the windows etc. Then go for a drive and see if it persists. It could be a battery issue. 70 degrees is definitely up to temp, so that is definitely not the issue. Just curious but what kind of voltage does the car read if you turn it on without starting it? Of course without the trickle charger connected. Sent from my SM-G930F using FerrariChat.com mobile app
I can do that Anders, but in the deal I asked the dealer for a non FIAMM new battery; they bolt a brand new Odyssey one wich is always on the tender when the car is parked. At least it will reset. I wonder if I can find a tool like my Durametric but for the Fcars? If the weather permits I will go for a longer run tomorrow to see how much it needs to reach all the temperatures ok.
This happened to me after changing the battery. They didn’t reset to factory settings after the change. Manually switch off the battery, wait 10 mm, manually reconnect the battery. Turn the key to position 2 without starting or touching an electrical component, wait 5 mm, start the engine and let it run 10 mm slowly without touching anything. The problem is therefore solved.
I'm not sure the F12 has a limiter when it’s cold, I know the Superfast does as I got quite a surprise when it would not rev. when cold, but after 3 miles it was fine and this was in spring. Can anyone confirm their F12 has this feature? If not I will try mine this week weather permitting.
Ok my battery is wired off for now, I will reconnect in a few minutes and hope the weather will allow me to test. Will share...
Ok guys, Battery reconnected. I fired on simultaneously the FF and the F12 and tested in the garage, both weren't fired since yesterday: -the FF revs freely since 70°C water and 50°C oil (didn't tried colder, and didn't over 6000 anyway) -the F12 revs freely since 90°C water and 85°C oil, not 50, not 60, not 70, not 80°C! I don't think the battery job had any influence.
Update: 30 minutes later engines off, I fire on the F12 and test again: the engines revs freely with the oil at 70°C...
just took my early 2016 F12 out, just as oil temp reached 60 I dropped down a few gears and went straight up to 8000rpm. if your car is newer it might be different, they had software change at some point in 2016. Mine is UK car.
Btw, when the both cars were reving side by side we could notice the FF sound was "deeper" vs the F12 sound (FF is 43000km and F12 is 5000km). On the other hand the F12 engine is a bit more "light" to rev vs the FF.
There is a few reasons why the F12 sounds different and revs faster. The sound difference is because of two things. The F12 has equal length headers with 6-1 merge collectors. The FF has headers that are 6-2-1 without merge collectors. The F12 engine also has higher compression which changes the sound. The F12 has a lighter flywheel as the car is lighter. This obviously means that the engine revs easier. However, the higher compression also makes an engine more responsive. Sent from my SM-G930F using FerrariChat.com mobile app
I take it you have plenty of fuel in the car? The F12 will restrict the power if you get low on fuel.
Fuel ain't the issue. But seeing that it now revs at 70 instead of 85, it might be fixing itself. The reset might have done it. See if it gets better. It should be able to do it from 60. One thing you should do which relates to how the engine senses oil pressure is this. Wipe your dip stick and go for a drive. Then stop the engine when hot and pull the dipstick again. See if the oil on the stick is foaming. If it is, the issue could be that the engine senses a low oil pressure somewhere. The engine has more than one oil pressure sensor from what I recall, so a low pressure due to aereation might not show on the display. If the oil is aerated have it changed. It is unfortunately an issue with some of the OE oils Ferrari uses. Luckily Ferrari allows you to run the oil of your choice as long as it is the right weight etc. I personally prefer Royal Purple performance oils. Just something to consider. At any rate, the car needs to go in if the problem persists. It might be as simple as a bad sensor. Sent from my SM-G930F using FerrariChat.com mobile app
The engine still reved at 70° once warmed to 85° from dead cold, not sure next time it will rev as soon; I may try today when the road is dry... The car is freshly serviced (oil, belts etc...) and checked for the 24 months factory warranty, it should be perfect!? I can check for foam in the oil of course.
In warm weather just let the F12 idle and go through its warmup cycle. Once the oil and water gauges start moving they will move quickly and the idle will rest below 1K rpm. Then just drive on Sport for maybe 10 miles and flip to Race or above and manual mode. Keep below 4K rpm for a while and then you can start pushing it. You will be road limited very quickly in that car. If your F12 fails to rev using this procedure then take advantage of that 2-year warranty.
I had the same experience with the F12 and now the 812... but the restriction only last for a couple of mins after I started the car and step on the gas.
