Hi everyone,

We now have the option to buy and install an Active LSD Controller on certain cars.
Could anyone tell me what are the pros and cons to having an electronically controlled diff?
I searched a bit on the topic but haven't found any stuff that made sense to my profane a¥¥.

Any help appreciated,
cheers
 
An eLSD will allow each wheel to receive the amount of torque it needs, and the control unit for the diff will change settings automatically to accomplish this. There aren't really any cons to this aside from complexity. As far as the game goes, I haven't used a car that can equip one of these, so I haven't seen if it offers any improvements or additional tuning settings, but if I find one, I'll follow up.
 
Driving a car with eLSD IRL I can say it’s nice, but then again I don’t have proper LSD experience to compare it with.

Gamewise, idk.

Of the cars I've owned thus far, none of them can even equip an eLSD. Can anyone give a few examples of a car that can? I'd love to see for myself what difference it makes, thanks.
 
I'm sure the few cars that can equip it, there's a performance issue in that car that would explain the need.
Snuggle mentioned the Berlinetta for example, that car is an absolute mess. 5000lbs of dynamite on a chassis that can't handle any of it (and thats just talking about STOCK lol). In order for it to handle the power it comes with it needs to be heavier, as it's just an overpower extreme. Adding more weight in addition to over power creates the worst gas hog and tire wear vehicle possible.
But anyway.
So it could be that these few cars actually need something special just to make them drivable.
Just thinking out loud, lol.

GT-R Nismo (the road car, not LM longboi) can also fit it.

I tested stock LSD vs Full Custom LSD vs Active LSD at Maggiore. All other parts & settings are stock.

Active LSD cannot change Initial setting (locked at 50 50), so I changed the FC LSD numbers to match it.

In terms of putting power down, FC LSD is the best, followed by Active then stock. Stock/Active just has a bit of unpredictableness to it (not aided by the oversteery GT7 physics).

I'm betting PD's e-diff simulations are probably pretty basic to begin with, and installing an Active LSD to tinker with some parts of it even further is just going to make it even messier. I'd rather stick with the FC LSD's fixed numbers. At least you know what you're getting at all times. But then again I'm not an expert tuner like @praiano63 and I didn't spend a lot of time with it to make it work.

Nah, that's the problem with GT physics. If the real car is like that Ferrari would have lawsuits all over the place from rich dudes crashing it every time they roll down the street.

I drove the 812 Superfast in Assetto (even more power than the F12) and it's a joy to drive. Not intimidating at all as long as you keep TC on. Same with the LaFerrari and other high end supercars.

GT has never been accurate in simulating these modern machines because they came with all sorts of electronic chassis control systems that isn't simulated properly in the game. And the lack of rear tyre grip in GT7 just makes these problems worse.

The Ford GT '08 has the option for an active LSD. I've not played with it heavily yet, but even on default settings (50/10/70 from memory), it felt a lot more nimble than the stock LSD.

I would have thought driving with a 50 initial torque, on a usual FC LSD, would be severely understeering mid corner, but this wasn't really the case with the active diff. I'm therefore wondering if the settings for active LSD and FC LSD aren't directly comparable. The range of numbers is a bit different. A bit like the Nissan factory viscous LSDs have numbers of 50/80 in GT7, and some of the Quaife/Torsen/Helical LSD in real life cars have a GT7 initial torque of 3 (whereas FC only goes as low as 5). It could be a different chunk of code for the various LSD types. A shame PD didn't let us fit a viscous diff as a tuning option.

I shall have to play with the FC Vs active LSD on this car. Stock, it's a handful in corners.
 
Adding to this thread as I've only just discovered it and used it based on someones tune of the F1 '94. Active LSD has helped me to better control this car at it's max power limits. It's still a little twitchy when putting all the power down, but I can control it more predictably and more easily than with FC LSD. Def feels like a game changer for me anyway.
 
Has anyone compared the same car with other diffs and found to see if there are definable differences or advantages is using an active LSD.

IIRC, I installed both on a GT-R R35 Nismo. What I can clearly remember is that the Fully Customisable LSD has more options to tune it, I mean, you have a bigger span of values when it comes to tune it than the eLSD.
