ok so I bought this ground kit off ebay for my 08...but no instructions were included. Anyone ever install one of these?

Thanks

It basically will attach at various grounding points around the engine bay. Doesnt really matter though. It wont improve anything at all.

 

yea. Pretty useless actually. Unless ur building an hardcore system.

 

I have been reading that it gets rid of the throttle lag in the tc...doesn't add any hp, just a smoother exceleration...any ideas on this?

 

There are a lot of grounding kit haters on this forum. Not sure why. I read some good things about it and decided to buy one myself about 6 months ago, and it does help. I don't care what the haters say, because I have direct experience. Well, I am not guaranteeing that an eBay kit will work, but I got a Ground Fusion kit and noticed a good difference. The throttle lag was reduced, the engine instantly idled 200RPM lower and has stayed that low ever since, and the best part for me was much smoother shifting of the automatic transmission. So you will definitely see a bigger difference if you have an auto, but it still helps with the idle and throttle if you have a manual.

The electrical guys will come in here with their ohmmeters and tell you that the grounding kit only produces a microscopic improvement in numbers, but I have experienced a very noticable difference first-hand. The lower and smoother engine idle can't just be down to coincidence, nor the smoother acceleration and shifting. The kit works.

 

look, the reason why they come in with the ohmmeters and such is because that is an actual repeatible, precise measurement of what the part is allegedly supposed to do.

your "oh, the car had less lag, and accelerated and shifted smoother" is not a quantifiable measurement, it is a qualitative measurement subject to a wide variety of perceptual errors.

as for idling 200 rpms lower, gotta call bs on that, what was your car idling at before? where is it now?

look, if a cheap-___ part like that really could do all those things that you alledge, and makes the car so much better, why wouldn't toyota put it on there stock? a cheap set of wires that makes the car idle lower, acclerate and shift smoother, and reduce throttle lag?

 

My tC would always idle around 700RPM before and it idles at 500RPM now. The idle as also much smoother and more consistent. No jumping around by itself, no rough idling. The idle also got noticably quieter. That was the most immediate difference I noticed after the install, even before taking it for a test drive. And it has remained that way for months.

Another cool thing is that headlights no longer get dimmer when I operate the windows and stereo.

 

From working in and around a shop growing up, along with my electronics background, I can tell you they DONT help the car run any better, period. If a ground kit made your car run better, you had a poor ground somewhere to start with. Fixing it would have had the same result. Cars come into shops all the time with issue regarding grounding (even brand new cars). Rather than slap on a pile of ground wires everywhere, the cure is to find and correct the faulty ground.

 

And idling lower is not necessariily a good thing. The car is set to idle in a specific range (and it will start at high idle and drop as the car warms up).

 

It really doesn't matter to me what you claim to have seen throughout your years of automotive and electronics experience. I bought the kit because I read enough positive comments to know that the positive effect was not just BS or a placebo effect. No one forced me to do it. I installed the kit and the difference could be seen instantly. You can try to explain this by saying my brand new car already had an electrical problem if you want, but either way, I "fixed" the "problem" for much less than the dealership would have charged. I didn't even complain of a problem to begin with, but the result was positive.

 

i have to be with engifineer...
I opted for one for my civic because i read the same reviews on them being positive for the electrical system... I started finding out that the same thing could be done by redoing the grounds for the vehicle... I broke apart the grounding kit, and used those larger gauge wire for my grounds... ironically, it did even better replacing and making better grounds than the ground wire kit itself...

 

Which is exactly what the grounding kit does in the first place, just with less effort.

 

and having a cluttered engine bay... doesnt look good... there is a reason why you can do a search for wire tucks and its tucking all the wires away... we already have some what of a cluttered bay (personally) why add even more wires?

 

I actually think it makes the engine bay look better. The Ground Fusion kit looks clean and professionally made, not like some of the eBay kits. The wires are thick and solid and wrapped in plastic in your choice of color. You can get it to match the color theme of your engine bay.

 

care to share a pic?

I can't get you a pic of mine right at this minute, but here's a yellow kit installed (found through Google):

 

Nevermind, I just found a pic from a few months ago. This is mine...

 

maybe a bigger pic?
