I've done both upgrades ('12 IS-F Steering ECU & OS Giken LSD) on my IS350. Here are my posts with the changes I've noticed for both performance mods:

thanks for the input on the 2011-2012 steering ecu. i think this has been discuss on the isf section already. what we still need is more information on what is the difference between '11-'12 and '13-'14 ecu or if there is any at all to justify the $200 increase from the '11-'12 model. lucky you have the lsd...i am looking at that next as well.
