DIY: Groundwire Kit - Page 5 - Toyota Yaris Forums

I was wondering about that. I don't want to sound like an idiot but I don't see how it can increase your hp. Would you just get a better spark?

On a new car it won't do much if anything.
However better grounding can allow engine sensors to work more efficeintly becaise of equalized resistance.
Overtime ground points and connections can become corroded and rusted and poor ground can result in higher and lower resistance, poor ignition or false/poor sensor readings.

I have seen cars like my own Laser that did have several rusted and corroded connections after 10~15 years of driving. Components like the throttle body bolts and studs were really corroded badly and add to that a gasket between that and the head there is a possibility for a very poor ground. And adding a ground kit as well as cleaning up the original equipment grounds will help restore proper grounding and lost power. In my case I went through 3 alternators in a couple months and finally talked to a Mitsu mechanic for a rally team and he told me to clean up the OE grounds and add a few more to or close to the most important components to equilize the resistance. I did that and never had any more chrarging problems and a better steady idle. But that's it on a 12+ year old car, driven daily with 300,000k.

With gold terminals you don't have as much or any corrosion so over time you maintain the same performance.

I've heard almost every possible "felt difference" from other members from other boards about adding a grounding kit.
things like
faster 1/4 mile
Lower rpms at cruise speeds
Faster warm ups
Better throttle responce
Quieter engine
Fact is 99% of so called felt gains are bullshit. People get it in their heads it's going to help increase power and will swear it did. a basic Placebo...
Companies will tell you what you want to hear to sell you a product but for the most part these kits don't do any of these.

It's another marketing point for ground wire/voltage stabilizer manufacturers when they sell these types of products.

My goal is to strengthen the ground connections of the vehicle to reduce fluctuations in voltage, and hopefully reduce this sort of fluctuation on electronic components.

well said

Hey itsmydaily,everything fits fine with the Tanabe strut bar installed,just make sure they dont toch,i got some sparks,but thats because I installed the kit after the bar,alot harder.I only have the alternator and the intake hooled up at the moment,I also have my voltage stabalizer installed,I deffinitly notice the car is smoother,and when I start the car,it starts quicker,and the starter sounds stronger.

Katana · 11-11-2006, 09:02 AM

Guys do I need to buy a complete kit, like the one the guys above bought from ebay?

I have a custom one, but there are only 6 grounding points.

hasher22 · 11-11-2006, 09:04 AM

You ground what u wanna ground.

vodkalush · 11-11-2006, 09:06 AM

I made mine. Easy as crap.

thankx, thats good to know. looks like I'll be getting the strut bar then

Got any pics? I'm curious to see where you mounted the voltage stabilizer.

eco · 11-11-2006, 11:44 AM

Ok,Ill take some pics today.But if your curious and cant wait,I mouted it between my battery and fuse box.

hasher22 · 11-11-2006, 10:28 PM

My curiosity on this grounding kit

http://cgi.ebay.com.au/New-JDM-Groun...QQcmdZViewItem

hmmmmm should i? its just looooooksss soooo pretttyyyy......

the_saint · 11-11-2006, 11:18 PM

For $85....I'd pass.

wow never seen one like that before, good find, but not worth the price.

eco · 11-12-2006, 12:01 AM

It looks like that stabilizes voltage aswell,but I think youll have a very hard time mounting that,you may,but you will not be able to see that voltage meter.Ill post the pictures of my partial install tomorrow morning.

Yes but do I need more grounding points?

You don't need to have more. six is enough and even five would be enough. Only put more if you want to add more grounding points. Otherwise six is plenty.

hasher22 · 11-12-2006, 03:54 PM

I believe there are 6 main points to ground. Though from what i heard/seen u can have 13 grounding points......correct me if im wrong...

nsmitchell · 11-12-2006, 06:35 PM

Well here are the results from my grounding kit:

W/O GROUNDING KIT
---------------------OHMS----VOLTS
Alternator----------- 0.6-------0.02
ECU-------------------1.7-------0.005
Throttle Body------- 1.2-------0.011
Transmission-------- 0.6-------0.016
Head------------------0.7-------0.016

WITH GROUNDING KIT
---------------------OHMS-----VOLTS
Alternator------------0.6--------0.011
ECU-------------------0.6--------0.008
Throttle Body-------0.3--------0.001
Transmission--------0.1--------0.009
Head------------------0.5--------0.009

The Ohms were read while the engine was off, volts while engine was on. The readings were taken using a Fluke 87 Ohmmeter. The leads were placed, red on the bolt being tested, black on the negative terminal on the battery. The volts were a good indicator of how the resistance was reduced, since the more voltage flowing through the grounding wire, the less voltage drop across the voltmeter. If you wish, I can tell you exactly which bolts I used for my hookups/readings.

I will tell you this, I can detect a small difference in the pull of my engine at higher speeds. It feels a little more willing at higher RPMs. Nothing major though. Idle doesn't really feel any smoother. I'll let you know about any MPG changes, if there are any.
