Does anyone know anything about them? Nissan offers a very intricate earthing cable system for the 350Z. It connects a common ground to about 6 different points on the engine. Here is a single earthing cable done on Foe's S2000. I wonder if this helps with the spark ignition?

Can anyone shed anymore light?

 

I wouldn't think it would need another ground but maybe they know something we don't.

I also have been curious about this. A shop i work with has been trying to push one onto me as well. They are relatively cheap and not too difficult to get running. Its suppossed to help if you have an upgraded stereo and help with headlights that dim, anything else?

 

HKS do a very good system called "Circle Earth" which is gold plated for better contact, look's very nice to.

If this is one of those "active grond" systems, you're wasting your money. Not much point in even getting into a discussion, this crap is like the tornadoe intakes sold on TV....they're designed to do one thing, and one thing only...remove money from your wallet. Buy a thicker ground cable and be done with it.

You can certainly improve on the grounding system in most vehicles since mfrs. attempt to get away with the minimum wire footage and minimum gauges they can. I have seen grounding/wiring systems for headlights that DID improve performance.

That being said, I think it will only offer an improvement to high-load electrical items. Items like sensors and spark aren't going to gain, and as such, you will gain 0HP from any of these systems.

 

Hi. Just want to share my experience, not trying to convince those earthing wires work.

I've installed an Apexi RSM for one year and it has a function to measure the approximate horse power. Normally it will record around 200ps max at around 8k rpm.

I bought one of those earth wire several months ago, though with all the electronic or electrical knowledge I got, I believe it SHOULDN'T help horse power... it should help old cars in some way but not for my s2k... why I bought it is because of the recommendation of a Japanese S2k guy.

However, after installing the earth wire, I got 221ps at the first test! Ambient temperature and everything stayed almost the identical.

Anyway, it could be because of the effect of reseting ECU or something, but I do feel a better pull after having that installed. Not bad for the relatively cheap price of them and I'm quite happy to keep it there.

But there are many friends found nothing difference after installing to Civic or so.

 

Peter,

No way in HELL that thing gave you 21 hp, and I would bet my next paycheck on that (which is amusing considering I'm out of a job at the moment....OK, I'll buy all contributers to this thread a beer).

I would want to see "back-to-back" dynos on the same machine, and after you've let the ECU relearn. Killing power to the ECU and then rerunning a dyno is definitely going to give skewed results, unless you pulled it fresh both before and after.

These systems are no different than using electric shock to lose weight, or drinking rhinocerus tusk to make your hair grow back in....flim flam artists, plain and simple.

 

It's a miracle marketing breakthrough!
