When accelerating though a corner what I noticed was the car pulled though the corner, opposed to just going though the corner. I also installed a LSD on my svt track car that had been sc before I installed the diff. I didnít have the same night and day reaction when I did the installation one that car but it could be due to the stiffer suspension and stickier tires. However it did really help with inside tire spin on tight corners.
There are several benefits to a diff, one the power the st has it really does not get out of the corners as quickly as it could. When I tracked mine last October the car was fighting for traction one of several tight corners. I know with a diff I would have picked up 5mph up the hill if I could have put the power down. Everyday benefit, traction, my 07 ST has a turbo and make 230 to the wheels it my dally driver, rain snow mud whatever. And the diff make a world of difference, I have a set of show tires on it and have never felt uneasy about driving that car in any winter condition. Even with the turbo if I brake the wheels loose it both wheels and very construable, it put that car against any 4wd car in bad weather.
As for you question regarding the ECU Iím not positive however my thought is it probably not going to have any real adverse affect on the car. The computer is most likely detecting the difference in wheel speed and then applying the brakes, the tq vectoring is detecting the car torque steering and correcting for that. The Diff will reduce both situation there for the computer needing less impute to correct. And if the ECU does go nuts Iím sure it could be adjusted or turned off in a tune.
Thanks for the examples and the explanation. I have read several different web sites regarding the LSD and how it works. I watched a really cool video that actually explained visually how the limited slip works and compared it to an open differential and even toyotas brake differential system.
I figured that the ECU would just see less difference between the wheels in turns and would just compensate less. So this makes me feel a little better! Not that I felt bad before hahaha
