I know a guy who makes them himself and has sold over 12,000 of them at $34.99. Alotta cash for a resistor and some wires.

thats almost half a mill

p.s. okay, i don't know much about the sc400, but isn't the 1st gen SC400 and the 1LS use the same ecu?? i went on lextreme and check the spec, and they apperantly are the same. so i assume if they make aftermarket ecu, or mod ecu, wouldn't it work on our 1LS???

yea, but SC400 aftermarket ecu's arent easy to find...
and you will have to modify it, the harnesses between SC and LS are different.

Oh thats interesting, Can someone confirm that a soarer ecu can be used on a ls with a simple play with the wiring.

This guy makes Soarer ECU mines style in australia. But they are not cheap. Probley same price as a mines, But this one you select different tunes and set a 8000rpm rev limit (dammmm) haha.

Very good for me

I love it how my celsior breaks out and looses traction when stomping it from 50km/h

That made me laugh!

For those that don't think ECU tuning does anything.... has clearly never experienced it. No, it's not like adding a turbo to your car. But it does add power, but more importantly makes a significant difference in drive ability as well as improve gas mileage (typically, not in every case).

Well I had my Lincoln LSV8 for the longest time and had it chipped. I know what you mean...it made the shift time alot quicker, reved higher and added a little more power. The response of the throttle was almost instant too, so yes the ECU makes a total difference in driving a car. The main difference in an upgraded ECU is basically ridding itself of alot of its restrictions - hence the added power and higher shift points.

But I mean its not much to brag about peeling from 50kmh...(thats 30MPH) when you have sedans out there that will burn through 2nd gear and bark 3rd.

That's a slightly different subject though. Ok, a lot different.

Why because it's a comparison to other vehicles?

Yep! Interesting, but no point. An LS400 (or LS460 for all that matter) will never come close to an M5 or a E63 AMG. How the tuning affects the individual car is the only critical item, at least not for our purposes.
