At http://l-tunedparts.com/product/?id=2925 I found:


The new Toms Linear Throttle Control System is designed to help your vehicle achive much crisper and direct throttle response. As is common in many electronically controlled throttle systems, you don't always get the best throttle responce from the vehicle. The Toms control unit fixes that.

However, this controller is not working on a LS600:



I found another one and like to install in the ash tray later:

At the filling station and after a race on the highway a Corvette owner visited the LS and was surprised that it is not the Mercedes AMG he expected. The Corvette with 500hp only won the race as the LS600 is simply too heavy and limited at app 165 mph (on 22's).

Does this increase 0-60 time or what? Im confused on what this exactly does but I am very curious if someone can clarify

I have heard of this device but on my 600 in PWR mode..there is no issue whatsoever when I hit the throttle..its very responsive

On the 460s, it helps reduce or eliminate lag time when hitting the gas..especially going WOT from a dead stop..I think its equivalent to when we put our 600 in PWR mode setting is what they experience in the 460..no delay..instant response. Doesn't make car faster

When there is time I can measure the acceleration. The controller makes the LS600 much more responsive also compared to the PWD mode. Btw. I never used another mode as it is the hybrid mode adding the power of both engines.

Normally the LS can remember how fast the driver pushed the pedal down and adapts the response. With the controller, this seems to be off. The difference is really noticeable. No doubt whether it is needed for a limousine.

And right, it doesn't add any HP but takes all what is available. If my calculation is correct the LS600 has 618 HP assuming the battery can deliver enough.

For sure a linear throttle controller is not recommended for grandpa's in their comfortable chair or countries where the speed is limited, LOL.

Would putting a 460 in power mode using the toggle switch (Power/Snow) on center console result in the throttle being more responsive?

@whitetooth, just curious how did you come up with 618hp for the 600?

CJITTY

Published LS600 HP is 438 but Whitetooth is in Germany and they have a different horsepower measurement which is where he is probably getting that number from. Or he is adding up the HP from the gas and electric motors but the work in conjunction with each other..doesn't really pile on horsepower..more of a blending if that makes sense

From Wikipedia: The*Pferdestärke*PS (German translation of horsepower) is a name for a group of similar power measurements used in Germany around the end of the 19th century, all of about one metric horsepower in size

We disucsed this at a mee about three weeks ago when member 'Ronshaft' told us about Pedalbox and Sprnt Booster ($289) that will do the exact thing theTom's product does.

I saw Ron this past Sun he bought the Sprint Booster, I'm looking to hear his thoughts. I also want to see drive it myself and he has the Joe Z exhaust so should make a great combo!

CJITTY

I can't imagine my repsonse being better than it is in PWR mode..with that CVT transmission we have in oir 600s...the car just pulls like hell in that mode. .plus quick taps on the accelerator puts you back in your seat

I had a sprint booster on a 911. It went out on top of a bridge on a two lane highway. I had to open the door crawl under the dash, remove it (five minutes) with traffic whizzing by to get home. They did offer to SELL me another one. Pass.

Oh hell naw..wow

Thansk CJITTY, I never really put it in PWR mode until I saw your post and tried it yesterday. Surprised how much of a difference I felt. I also feel that when I let off the gas I feel the regenerative braking more as well. Have you noticed this or am I just imagining things?
