Fully adjustable steering feel! A comprehensive HOW TO vid.

- Every 2GS steering ECU has a resistor that helps control steering feel. Lower resistance = firmer steering. Higher resistance = less firm/feedback from the system. Thus far we have confirmed the resistor values on the 2GS as follows:
98-00 2GS: 4K ohms (numb)
01+ 2GS: 1.1K ohms (good feel)
GS430, L-Tuned, Sport Design: all measure the SAME!
If you're interested in just going with a lower resistance steering ECU, such as the one out of the 2GS/430 (1.1K ohms), I made a vid on it back in the day.

However, if you want full adjustability within the confines of the physical system, a potentiometer mod is your ticket and you should continue watching this video.

YES !!!! ANOTHER LEXUS GS VIDEO FROM THE LEGEND!😊
Great video! Nice that you documented the resistance of the resistor that was removed and did the same for the later model PCBs for comparison. 👍
Found out about your channel through a friend that has a gs400 and started watching your build from the beginning…and I have an LS430 lol, just love the amazing content and information. Please continue to document your builds!
Thanks for reminding me of this mod. A member from the JZXProject forums did this to his Cressida over a decade ago and we kind of forgot about this mod. If I remember correctly, I think he said it was overheating until he disconnected the ecu from the speedometer since it was speed sensitive.
Bro you come up with the coolest ideas lol..love the vids, my sport design 2002, tightens up a lot after 60. Or maybe it’s just my grip 😂 anyway keep up the good work
I wish I came up with this! 😎 I’m just passing along cool stuff that really works. I believe the chip/logic increases feel as RPM/speed goes up, but I don’t know that for a fact. What you said about your SD would corroborate that, so it makes sense. Thanks for commenting!
@@ForwardMomentum the thing is that the steering pump has a valve (or valves) that controls the "firmness". Aristo got it controlled by a vacuum (higher RPM - stiffer the wheel). early UZ engines are also using vacuum line, GS400 and GS430 are using 2 valves: 1 vacuum and 1 electronic valve. This small PCB is responsible for controlling the electric valve on a pump but not directly - it sends the signal to ECU that checks the speed and also changes the signal to valve on a pump. There are many many ways of tricking and adjusting firmness of steering on early toyotas but this one is the easiest and most "effective" one))
@@ForwardMomentum Yes, they refer to it as PPS (progressive power steering) in all service manuals
Thanks for posting.
I wonder if an online vendor sells these already modded.
No one does. Probably because modding one takes about an hour. Then you have the whole core return process, etc. In the end, charging $75 and $125 (no core) would be the price. I really don’t think people are willing to pay that.
Do you have a video on replacing the valves to fix the hot/cold air in the dash. Love all the vids you put out just wish i hadthe v8
I’m sorry, I don’t have one yet on the air mix servo / blend door. Thanks for watching!
What gauge wire did you use?
Update: I did one last week. Just put it in today. Definitely works. I think I just had a higher expectation of how I would feel, or maybe how extreme the difference would be. Absolutely works though. Cool mod. Total cost, about $25.
I believe it was 14, but it doesn’t matter much. 14-18 should work well (it’s mostly a constraint on spacing vs performance).
@@ForwardMomentum any idea how much the resistance from the wire size plays into the way it performs? I'm going to LKQ first thing in the morning to hit all the GS'! Thanks for another banger of a video!
I’m sorry, I didn’t test that. I cannot imagine any measurable performance difference in the 14-18 ga realm at these levels, using a 10K POT. I’m no EE, but I really don’t think it would be a significant factor at all.
@@ForwardMomentum hey....I'll take your word for it. Thanks again!

Is the resistance still speed sensitive with this mod?
All other functions of the ECU remain. So it functions like the stock ECU, but more firm in the same conditions if that makes sense.
Hello I have a question for you I have a 06 gs430 and it just started doing this when I drove it yesterday and went to slow down and stop it started jerking what could that be thanks
Check for codes. Could be TPS related.
Just bought a 2001 gs300 turbo, I believe it’s the same color as your G. Cinnabar pearl?
Yes, code 3N1, Cinnabar Red Pearl. Congrats on your turbo 300!
@@ForwardMomentum love all the gs300 content you’re putting out for the community. Stay awesome!
Any reason to not get a 5k or lower rated potentiometer instead of the 10k mentioned? since even 5k ohms it is more numb than early models.
Good question. My answer is that 10K gives you a lot more flexibility. Want to turn it to super easy? Take the dial to the 9.5K ohms max (as shown using DMM). Also, some guys that drift have indicated they wanted the steering feel to be super light to help them drift. A 10K would give you all of the above. In the end, 5K would also work for most people though. 👍
Did you dyno after the supercharger?
No. My friend did (same car and very similar mods) and was about 325whp. I figure I’m about 315whp (stock is 235whp).
