i have seen the posts about ground wire swaps i was wondering what everyone thought of this. i would spend that much in wire anywayshttp://cgi.ebay.com/ebaymotors...QrdZ1

For 25$ why not.... grounding DOES HELP A LOT, the factory uses just what it takes to get by... and if you un-bolt the factory grounds it's likely that there painted under, so only the bolt itself it making contact... If you have a system you should consider this as well.... although some of those wires could be beefed up as well.... Being that the kit is 25$ total, i would be concerned that the terminals wouldn't be soldered to the wire... if they are bonus, if not, it's just asking for corrosion...They can be easily made as well....

Oh, and a quick note, your not swapping ground wires, your adding to... the more the better..

looks like there is shrink wrap on the ends so i shouldn't have to worry bout corrosion.

From personal experience, I must comment that groundwires offer little effect, if any, to the performance of your vehicle. See my How-To post and follow-ups:http://forums.genvibe.com/zerothread?id=19541

If your crafty you could solder them yourself if need be... just go get some replacement heat shrink and well, you have to use a torch to solder those end but as long as you heat the terminal and not the insulation, you won't melt things to bad...

See my How-To post and follow-ups:http://forums.genvibe.com/zerothread?id=19541I see what you are saying, but, at the same time, you DID show improvement, i didn't read anywhere that you re-set the ECU by disconnecting and draining the memory caps and then running a "learn" program..(although the install would suggest it).. so it in fact took some time for the car to "learn" the change that you had made. Using increase in mileage to determin the effect of a mod like this is VERY subjective in nature... i mean it's only wire your adding, but the normal stress on the electrical system has been greatly reduced, even if it doesn't show up in milage. It's not the type of mod that net you any REAL gains (well on subarus it can, different story though) more of peice of mind type of mod that things simply arent stressing like they had... Where this mod REALLY shines though, is in stereo installations... Thanks for the info though, this is a HUGE deal in the audio forums over on my Subaru site...

Yes, I did show improvement, but then, I'd also added a CAI and dropped the vehicle in the timeframe of the later followup test and they may have contributed to better performance as well.My install was done with the battery disconnected until the final connection (more than a couple of hours), so I figure the ECU was effectively reset. And, what do you mean by "draining the memory caps"?? I've never heard of that before.Also, regarding Suburu's and GW's, here's an interesting thread at the NA Subaru Impreza Owners Club.

With that being said, you can't tell WHAT gave to the improvement, really, can you? If you did the CAI at the same time, there could have easily been gain or loss from tat as well... But likw i said, it's just wire and some cars electrical systems are built much better than others, so who knows for sure... Quote »what do you mean by "draining the memory caps"?? I've never heard of that before. The ECU has a series (or single) capasitor that acts as a battery, it keeps the ECUs memory functioning when the battery is dissconected for a short time, usually about 1/2 to 1 hour or so.... By dissconnecting the batt and leither letting it sit or hitting the brake pedal for a seccond, you drain that cap and clear the memory on the car.... Then when you start the car again, it goes into "learn" mode and samples more to "learn" all the various parameters of the engine again...you already did it when you reconnected the battery, but the proper proceedure would have been clear the ECU, start the car and drive long enough for the cooling fan to come on, meaninig that you were up to proper opperating temp. then when you shut the car back down, the "learn" function ends and your car has effectively learned any new mods done.... It's a good way to clear CEL codes to...

Grounding wires won't get you crap, except $25 poorer. (Certainly on the Vibe, anyway) Send me $25 and I'll pray for your engine. It'd probably give you a better return on your investment than ground wires.

All of you make good points. On the one hand, if you are installing a large stereo, the extra grounding should help in that aspect. A better ground is a better ground, however running wire all over the place just wastes wire if it doesn't improve anything. On the flip side of the coin, if you are looking for performance gains by adding more grounding (on the vibe at least) you probably wont see much improvement. just my two cents.

[satur9]

those are the wires i have.i have crazy electronics in he car so extra grounding helps.power wise idont know. i will say that if you put a gound wire on the exhaust header heat shield bolts. your exhaust note will be deeper. i noticed it adding the wires. and now i miss it cause i took off the heatshields for my header.

I did a large stereo install and have TRD ground wires and I noticed nothing. The lights still dimmed and the battery couldn't keep up until I installed the cap now everything is running great. I think the cap did way more then adding the extra wires save your money.
