EDiff overide by Scud Ing Swiss

I really doubt ferrari developed this system to make performance worse, if you deactivate this im sure there is a host of other things you could also do without.

I vote to keep it in tip top shape instead

 

Easy install (maybe 15 mins tops) & car feels more fluid. Maybe all in my head. I don’t have spacers.

Ray has driven his more, I’m guessing he’ll be along to comment soon.

I bought and installed for peace of mind, and because I once drove around (by accident) on ‘snow’ setting and could feel the additional ’help’ at the rear…..didn’t like it.

Removing a (potential) point of failure was my motivation.

In full disclosure, I have the F1 relay too and am a fan of Stef’s products. No other affliction.

PM if you’d like more details.

It's mismatched wheel sizes front to rear that cause E-diff problems, not wheel spacers.

I installed the SEB on my 430. A simple limited-slip differential would suffice. Why they choose to go with a failure prone electronically-controlled valved differential is a mystery.

You can always reactivate the E-diff with the supplied remote.

I have almost all of the Scud-Ing products for my 430. They enhance the usefulness, safety, and reliability of the vehicle.

Can’t recall the date, but as soon as he started shipping. No issues from me, gives me peace of mind.

I would take some of the claims around the benefits of the ediff blocker with a pinch of salt. If you like how it drives (with an open diff) with the ediff inactive, then go for it. I think it mostly serves the needs of enthusiastic owners with a desire to tinker.

its really hard to keep the e-diff healthy without big bucks.
I encounter one of 430s around me that had the cover cylinder (whatever that is, its difficult to describe in words) worn and leaking red fluid.
Ferrari doesn't list that as a stand alone part, so, you figured.

 

So is the ediff OPEN most of the time. For example if someone is driving around town just scootin along normal driving it is open correct?

 

Interesting will have to wait and here more first hand experience. I have the really and have no complaints, great product.

yup.

 

I'm not doing the usual patronizing 'try using search' but simply sharing another thread that has a few other opinions in it.

Enjoy.

 

Almost every manufacturer has gone with a variable electronic diff on their performance cars. It does have a performance benefit, and that's what the manufacturers are after. The cost to maintain is generally not a concern.

The race cars don't have an e-diff because the wear rate from slicks would cause reliability issues. Porsche even recommends not fitting slicks to PDK box GT3s, as the e-diff can't cope with the increased grip levels long term.

The only reason to buy and install this override is because you don't want to spend the money to maintain your car, which feels silly. There are so many ways to reduce cost of ownership (if that is a concern) that could be undertaken before disabling a performance benefitting system. If you are taking your car to a dealer (or even an indy) for annual services, brake jobs, etc. there is a ton of money to be saved. Do those things before installing a part that objectively makes the car worse.

 

Yes, as it is with all types of differentials. This (relay) is a solution for a problem that simply does not exist. A variable differential that reads all the forces of gravity that are occurring in performance driving is nothing but a good thing for a non-pro driver...To circumvent the system to save operating costs is simply another way of saying I can't afford the car....There's always the Manetto to turn the diff function off for those "cost conscious" drivers.

 

Does the off function on the manettino turn off the e-diff as well, or is it just all the other nannies?

 

The 430 models they build for the track do not use an E-diff, just a simple Limited Slip Differential.

I do all the work on my car myself. I probably maintain my car far better than you do. My F430 is in better shape now than when Ferrari assembled it.

I can't afford to maintain the car at the prices the Somali Pirates charge for parts and labor here. There, are you happy?

I'm a retired working class guy who owns a Ferrari. I didn't rob old ladies retirement funds to buy it. I used some of my 401k plan to pay for it in cash.

Anyone who doesn't work on their own car is a dilettante. A dilettante with money, but still a dilettante.

I have put over 2,000 miles on the car since installing the SEB ... no problems, better handling.

Ray

 

Without the SEB installed and activated the computer controls application of the E-Diff clutches. Depending on the data it receives from various sensors, e.g. steering angle, vehicle speed, lateral acceleration, et al, it will apply pressure to the clutches. With the SEB activated it becomes an "open" differential although Stef states that there is a minor amount of clutch engagement. See his explanation for further details.

When you go to Cars and Coffee no one knows your E-Diff is disabled, just as they don't know that you never turn the radio on.

I've had my SEB installed since February around 1500 mi and think the car is more nimble flexible what have you. I did track it once with it on and off and couldn't tell much if any difference. Considering that the E-diff is a failure prone system with great expense and downtime potential, and one where my meager driving skills are unable to discern any distinct performance enhancements, I chose to install it. I had an indy mechanic go over the car prior to a low grade tracking event, and they were ok with it and approved it for my uses and abilities. I have had no problems with it whatsoever and think that it quiets down the whine a bit at 80mph in 6th gear, I don't think it is an insult to a Ferrari design, my competence or to my maintenance choices of expenditures. It is an improvement IMHO. YMMV. Your call. Opinions are cheap. Everyone's got one. I, for one think that Stef Van has improved the safety and driveability of the car immensely and have not seen such high quality in electronic aftermarket devices anywhere.

 

But all F1 cars since Schumacher helped develop it, use it. It allows you to go faster, safer.
I thought that boat anchor would be gone by now?

 

How many threads have there been about e-diff failures? I can recall a few about a relay, or something. School me about these extreme, expensive failures that I need to avoid.
Again does the e-diff turn off on the manettino?

 

When the E-Diff fails you are, if you're lucky, in limp home mode.

The E-Diff Solenoid valve sells for $882.00. The E-diff pressure sensor sells for $544.33. Both at a Ferrari dealer on the east cost where I buy parts that Ricambi does not stock. I never buy parts from a California Ferrari dealer.

Ricambi sells the solenoid valve for $603.09, and the pressure sensor for $328.21.

The labor rates to install these parts are staggering.

Failure of either basically immobilizes the car. The AAA limit for covered towing is 100 miles, so if you are further than 100 miles from a Ferrari dealer you pay additionally for towing. This basically limits the range of a drive to under 100 miles. I drove brand new Corvette C5 and C6 Z06 cars on trips of well over 5,000 miles, to Banff in Alberta, Canada. I would never do that with a 430 with the E-Diff enabled.

The SEB simply makes the 430 more reliable.

For those of you unconvinced, by all means, do not buy a SEB.

What measurement did u use to determine better handling?

 

The challenge cars do use a traditional LSD - viscous IIRC. If disabling the E-Diff then personally I'd rather that it was replaced by another type of LSD, but I do see the benefit of having another option available to keep running costs down.
