I dont understand grounding?????

[biglu187]

I was checking out these grounding kits but I don't understand how upgrading the grounding of the car makes it run better. I work in the electronics field, so I know what grounding is but not how it works on cars. I have ran this by some of my engineering bussies and they don't know either. Can someone give me an explanation?:ermm:

Well, there are many many electronic sensors and devices in your car. Typically, the stock grounding is pretty poor, just a thin little wires that joins one part of your car to another. You could have a couple dozen electronic components running off one tiny wire. So you put some lower gauge wire in place (or added to) of the pathetic thin ones so there's never any doubt that everything is getting all the grounding they need. Since your ECU relies heavily on the readings from the zillions of sensors in your car, and sensors need a reliable and consistent electricity to give good readings, that is why people install grounding kits.

Do you notice a difference? Well, out of all the grounding kits I've installed for people, nobody said it made a noticable difference in performance, but some have reported a slightly smoother idle. Also, some have said their display on their headunit doesn't dim anymore when the signal light flashes or when the sub hits hard. Pretty minor. I've never installed one on one of my cars, but if I ran into a kit for really cheap I'd throw it in anyways...

I have the apexi ground stabalizer and I did notice a difference. The engine no longer seems to bog down between shifts for one. So, there is a slight difference in acceleration. However, the Apexi kit is kind of costly and if I didn't get it for free, I probably would not have bought it.

I was checking out that apexi one on the web. I think I will wait. That $200 will be better spent toward exhaust or body kit.

What's bs is those people who claim they can feel a power increase with a grounding kit.:dead:
