I know that L-Tuned has a steering ECU for the Series II cars. Does anyone know if that is available for anyone to buy? A second thing is, what does it do for you? The only thing I can think of it that it removes a little more of the power steering, but you can't go much further. The steering is almost perfect in my mind.

Has anyone tried it?

Steering ECU? what is that? i have the L-tuned series II and i do not know what that does!

Maybe I'm mistaken, and the ECU is only for the GS, but I was fairly sure that when I was at the Lexus dealer, they told me that there was one, but I wasn't allowed to buy it for my car. You had to get it with the car.

I have no idea, I cant see why somone would havea steering ecu... but you might wanna contact steve ganz and ask him...

I think the steering ECU is only for the GS.

I wasn't sure that is why I was asking.

i know theres one for the GS...and i've seen it on the TRD parts list for the IS300

Yeah, that is what I saw
