Will post a review once I have installed it.

I bought a second ECU, just in case I screw this one up.

You in a gs3 or gs4?

I got a 99 GS3.

Yeah you can find them cheaper in the UK or Germany.

Before installing, I adjusted the potmeter:


3.2 kOhm, instead of 4.62 kOhm (stock, 560 ECU)

I wonder if someone with the L-Tuned ECU can shoot a picture of the internals. Like a really high res shot. Maybe we can compare the different resistor values inside the boards. I can snap some pix of mine from my 2002 SportDesign and the 2005 GS300. Then we can compare it to the L-Tuned. If it's just a simple resistor difference, then we can just all drop in the resistor value of the L-Tuned ECU.

i probably can.....i just bought a L-TUNED steering ecu and allegedly the GS430 steering ecu is the same but it may not be

Just for your info, 3.2 ohm is too low. Steering is underpowered and needs quite some effort. Need to tweak the adjustment a bit.

any update on this?

let's get the color codes of the resistors in the l-tuned and the 2 that jeff had and figure this one out. the steering ecu looks like a pretty simple design actually, and probably want to change out the 2 electrolytic caps while we're at it since they might have drifted in value over the years.

bump...

sakataj: did you get a chance to shoot pics of the internals of the l-tuned ecu?
