correct me if im wrong but ISNT the SD ecu the EXACT same as the now gs430 steering ecu? when i bought my car i started looking for one and chased down some info on them and apparently the 2001 gs430 uses or is the same steering ecu as the sportdesign ecu was so i stopped looking for one since i already had it essentially

I have no idea what the exact or true differences are. I just know that the SD's have different suspension parts to give it a slightly more sporty feel. I noticed that the ECU was a different part # as well so I gave it a shot. It wasnt a huge difference but it was noticeable. Sorry I dont have more info for you.

it's not bad when you're moving but when you're trying to park...it sucks! I had to drive around downtown and parallel park a few times and whatnot but I really missed my power steering. Now that I got a taste of what the L-Tuned ECU can do, I might have to invest in one...

Either way, the ultimate would be to either use the L-Tuned ECU, but that supposed to be the same as the one we have in the GS430 anyway, or ad the resistance in line to the solenoid so the parking entire Speed Sensitive Steering system still operates just at a lower value, or simply ad a speed sensitive cut off relay that enables the steering ECU at 5-10MPH and cuts it off anything higher than that. Since I've been driving around like this for a while I literally forget that its even disconnected. Now days the only reason why I'm conscious of it is because we are talking about it here. Other wise I've gotten so used to it that even the low speed parking doesn't bother me. That is why I haven't gotten around to adding the resisters or engage/disengage relay yet which was my original intention.

I just plugged my ECU back. Man is the steering much lighter.
I put it back because with the ECU off, the steering weight is random at low speed. Sometimes its heavy, and sometimes it's just a tad bit. Then the weight varies as I turn the steering (heavy, light, heavy light, etc). So now with the ECU plugged back in, the steering is smoother, but its light. I'll have to find a different way to make the steering heavier (

After it is all said and done, that is probably what I'm going to do myself and what I was planning on doing in the first place. Only reason why I haven't done it so far is because mine happens to be working just fine as is. Still though, eventually it is best to do it right.
