Saw how easy it was to install steer ecu so ordered one. Went to pull up instructions on how to open trim under steering wheel and it is no longer avail. on upgraded forum. Help, can we re-post this. I'm afraid I'm going to break some trim!
Location was listed as; BLEXUS.COM/ECU 101PHP

 

I have my ECU install.. with the instruction ... fairly easy... It took approx 40 minutes... However, like you said.. I could not find the link any more.. if you want.. I could fax the instruction that I pull off from the ECU 101..

 

Would love a copy of the directions, if you can e-mail them to Paulzjoh@mtnhome.com

If you only have fax send them to 870-449-5415, and send when you hear the prompt on the message machine.

thanks again!!

 

I will fax you the information tomorrow .. . utilize.. office fax....

 

www.super-lexus.com go to how-to section, i put up a copy on my site hope it helps u out!

 

The steering ECU is put out by the L-Tuned group of Lexus(http://www.ltuned.com). It is for the second generation GSs ('98 on) and effects the boost and feel of the power steering at various speeds. Sorry, it won't fit your car.

 

You da man, Sasha! I'm going over to Marty's to do his install tomorrow (Sunday) and needed a refresher before going over .

 

haha no prob dude

good luck with the installl today!

 

Hey, Sahsa thanks man. Nice to know bit and I will have an idea what we're doing today. I figured when he offered to help he knew what he was doing.

Now he's looking for the instructions!!!! I feel really secure having him pull apart my dash.

j/k

 

following instructions (thanks again,Shinchan)
I took out 5 bolts, and had one left over. Yes, I looked all over and could not figure out where the extra one belonged. No rattles after test drive, so what can I say.

Removing ECU, don't see how anyone could do it with a deep socet, I used a 12" extention to get it out, really high up on left hand side. For sure, you need a flashlight to see bolt holes and do not know how I could have ever found it with out a copy of instructions and photos.

Effect: I have a '99 Gs4, I've driven 2 days on the full L-Tuned pkg, springs, shocks and F&R sways. The hard parts made a great difference in the handling, just firm enough for increased cornering and not so hard as to upset the wife.

The L-tuned ECU has the same Denso part number moulded into it as the OE part that I removed. So I have to rely on L-Tuned honesty to make sure I got an "improved" part.
With that, I think there is a very slight increase in steering response, but after driving with just the hard parts for two days, can not really recommend this part. For $125.00 can not say the marginal improvement is worth the cost. Steering does not seem any quicker, seems to be a slight increase in stability as you don't seem to be making as many minor corrections while driving, either on straight or in curves.
