Upgraded Steering ECU: Does it really make a difference?

My IG: https://www.instagram.com/youtube_for... Early model 2nd gen GS300's and all GS400's allegedly have an "inferior" steering ECU installed from the factory, at least in comparison to the GS430 which, some argue, is the same ECU as the expensive L-Tuned version from back in the day. That said, the purpose of this video is to determine if the GS430 steering ECU makes a noticeable difference when installed into early model GS300's and 400's. INFO 1998 - 2001 (?)
