I just installed the L-Tuned Steering ECU on my GS400. Thanks, to Carson Toyota for great price and you guys for info on the installation. It took me 15 mins to install it, while spending 7 mins to look for all the extensions.
Comparing to original there is noticeable difference. Before, the steering was heavy when driving slowly, for example while parking the car, and it got lighter with speed. What is up with that? After L-Tuned installation, the steering is slightly lighter at slow speeds and it gets heavier with speed , the way it should be.
Also, as we speak, I'm getting the TRD says installed, and I will report tomorrow about my findings.

 

ChrisK: You are going to love the sways, especially coupled with the steering ECU. Congrats!

 

Thanks Mr. Johnson.

My goal is to install L-Tuned suspension this spring as well. I imagine I will be a happy camper after that. On of my friends owns 2000 540 with the sport suspension, and my goal is to run against his car when is nice and worm (summer time).

 

with the trd sways and shocks/springs, you will have a good run with me

it's sad when you don't even have the money for an ecu

 

This from the guy who recently purchased 19" Volks, Tein HA's and a big brake upgrade.

 

no, i am talking about myself no money even to get the ecu

 

rominl,

Sorry for misunderstanding.

 

I just had a chance to test the TRD sways. Let me tell you from the beginning. First I had 2003 ES300 as a loaner. When I picked up my car and drove it home, it felt very stiff and harsh, to the point that I actually had doubts about sways. When I got home, I took SC400 for a quick spin for comparison purposes. So, I drove SC400 and paid the attention to how it behaves on the road and taking turns. Then I took GS400 on the same route. Man, did this car felt sweet now. It wasn't bouncy, little harsh but not in a bad way anymore, turns were fun for a change. It is a new car and I'm happy. It actually started to feel as small as IS300. Can not wait to put L-Tuned springs and shocks on as the next mode.

Mr. Johnson,
You were right, the L-Tuned steering ECU and the TRD sways go together very nicely.

 

yeah, that's why some people say that the trd is too stiff and daizen is better. i have trd only so i can't say too much about that.

but yes, now your car is rock solid on the gnd
