Easy Fix to "Abrupt Shifting" 458 DCT

I have to say my 2014 458 spider felt this way will get it checked!

 

Thanks for the info!

All the more reason to get a lightweight Lithium Ion battery..

 

Periodically check the quick release clamp on the battery terminal. If the connector is not pushed all the way down tight before clamping, the connector can eventually vibrate loose and move slightly up the conical shaped terminal post. If this happens, the connector is held in place only by gravity. It will slip when you push on it and may even lift off with finger pressure. A loose connection means trouble for the sensitive electronics in these cars.

 

Sounds as if we should think of a new battery as part of every biannual major maintenance....what is one installed, $400 or so?

 

I started a thread in January entitled "The best $1500 I ever spent." In it, I spoke about replacing the battery. For the reasons you site and the electronics sensitivity in the dash and elsewhere, a perfectly functioning battery is a must.
Additionally, I would argue that because these cars are so computer dependent that going to your dealer - if convenient - to just clear error codes probably helps performance. View it like a computer at home that slows due to cookies etc. building up. Have them just hook up OBD and clear the codes. Takes minutes. Wouldn't be surprised if this helps drivability.

Lithium ion batteries can overheat and catch fire. I'd rather get a good AGM replacement like an Interstate MP-7/48.

 

To Melvok, grazie mille for posting my thread.
In regards to Interstate battery, much less than 50 lbs.
In regards to lithium battery, I cannot justify unknowns with fire risk, etc. Additionally, as I do not track car where any weight savings might help, it loses another of its benefits for me. Net, given all the above and the cost which I believe is > 1K (based on another thread here a few weeks back) I just don't see the benefit.
Rick, good luck with code reader -hope all is well - and good luck with the Li battery.

Sounds like Dale, a man who really knows these cars....

 

If I am not mistaken, Porsche now has Li battery option. If Ferrari had one as factory option I would feel better using one. NOT that I trust Ferrari implicitly. Lord knows the poorly engineered things they have done over the years. Rather, with the complicated electrical systems these cars now have, I am afraid to mess with any part of their manufactured equations.
Keep us posted.

I have to say the electrical system clicks and knocks when you are stop and go in traffic, have you heard that in your 458s?

Reducing the weight of the battery will definitely change the weight balance of your car and may adversely affect traction and handling. People put rear wings on race cars to increase pressure on the drive wheels, to improve traction, especially when cornering. Reducing weight on your rear wheels can make the car less stable in the corners.

I am also not sure the 458's charging circuitry will work on a lithium battery. Even the AGM battery has a different charging voltage level requirement from the standard starter battery and will not work 100% unless that is sorted.

You need to be very careful substituting a battery different from the OE unit.

No. He's completely wrong. Why would car manufacturers provide a charger that only maintains whatever charge the battery has discharged to - makes no sense at all?

The regular 458 battery tender is simply very weak when it comes to recharging the battery. It can recharge the battery so long as it is not already discharged beyond 50% capacity or so. But it will take more than a day to do so. However, if you buy a proper battery tender like the CTEK 7002 or 25000, they will can very quickly recharge your battery even if it's discharged past 50%.

 

My OEM tender says "charger" right on it.

Here you go Rick:

I have the 48cx in my Italia now for about 2 months and love it

I can get the same battery for around $1400 from my source, shoot me a pm
if interested, best

 

Anyone have suggestions for aftermarket batteries vs the OE one? I've heard Odyssey and interstate. Anyone know the model numbers?
Thanks

 

Great point! I think everyone with these cars would be best served by keeping the included tender packed away and using the 7002.

And here is a solution for connecting to the factory connector:

Just another quick question. I currently use a battery tender charger for all my other cars. It hooks directly to the positive and negative posts of the battery.
Would that be a better option than the factory included charger?

 

It's not about how it's connected to the car, it's about what it can actually do. The better CTEK models can and will maintain the health of a battery, whereas a cheap battery charger (the one shipped with the cars) can't. Get a better CTEK charger, pay for an adapter dongle because Ferrari cheeky, and enjoy a battery that will last much longer.
