Maybe you're expecting way too much from the grounding kit?

Everyone should understand that the ground potential of a car chassis is different at different locations of the car. Not all ground locations are ideal or optimized, clean or not.
Some factory ground areas are weaker than others. Anyone who is experienced with noise and power issues for high power car audio will tell you that a power amp needs to be grounded to a "good" ground location, not just any ground. Why? Well the amp will still work no matter where you ground it, but it may not operate at it's fullest potential if the ground is weak, plus this becomes a cause of audible noise in the system, in some instances identified as alternaor whine. Can the sound quality improve if an amp is grounded properly. ? Yes. So isn't it reasonable to say that the performance of other electronics in a car could be improved through better grounding, such as the ignition and tranny ECU???
The grounding kit "TIES" in all the factory grounding spots so that they all become "good" locations. In addition it ties in other locations where no good ground connection may have previously existed. There is a REAL improvent in electrical connectivity by doing this.
My only point here is to say it is "Possible" for a grounding kit to yield performance improvements in a car, however every car, model and type are different, so "Your actual results may vary". I won't elaborate as to what electrical part of a Lexus can benefit from better grounding, but if something runs better after installing this kit, then I just explained the reason why.

So you pulled it all the way to the stock tranny ground? I had to put my longest wire to the back of the intake mani since my battery is on the otherside.
I put mine on the chassis, intake manni, & Thermostat housing. I would love to ground one near he 02 sensors but that will require some welding to make a place to tap to.

mikal: I wasn't really expecting a really big gain, actually I was very skeptical and got what I expected.... pretty much no gain... I just really wanted to make sure I didn't do it wrong, or ground it in place that was obviously wrong... I will keep it on though, I am sure I am benefiting from it some how...
I will try moving the grounds around, maybe get under the car and try the tranny ground...
Or maybe be bold and do what the directions say and put one of them on the alternator ground...
maybe next time I am at LMS, I will have them do those two grounds and see what happens.
thanks for the info

The analogy is the same when listening to High End Audio (Car or Home). Many people report they can't tell the difference or hear improvements when they make an upgade, but after their ears acquire a sense for the nuances of sound quality, they can easily tell a downgrade in performance when they revert back to the original set up.
Food for thought.

RMMGS4:
I read your post before I bought the grounding kit and it made complete sense, I was actually going to try that...
I wanted to make sure if there was a consensus on where the best grounds were for starting the controlled baseline test.... then disconnecting them later to test for degredation...
thanks

Hmmmm....bringing this thread back to life....LOL.
I just installed mines....grounded to the alternator, tranny, and body. I have the Versa Cruise one with the muffler ground....which I attached to the header....connects to the exhaust.
Seems to idle better, but not sure about the other claims yet....time will tell.

sorry to bring this back from the dead, but...... i just got the H.V.S. Cyber Speed Version Voltage system and grounding wires. my question is what are the 3 best locations to mount them? i am thinking alt, chassis and block. any input would be helpful, but intall pics would be better. thanks
