thanks for ur input!

 

show me the proof that it changes the transmission shifting..they is no way putting a grounding kit on a car is going to make it shift any faster its impossible!!! you need to get in to the ECU and program it...

 

Your referring to the ECU which sends a signal through a bunch of wires down through the transmission which then sends a return signal up a bunch of wires and back to the ECU right?

OK, so if I sent you to the grocery store in a bunch of traffic and then a day with no traffic, which day would be faster? No traffic? Thought so.

Better grounds can clean up electrical interference = traffic.

Same timed signal from the ECU, but getting there and back quicker because of a "cleaner" route.

Pretty simple. If you can't at bare minimum accept the idea as plausible then your retarded.

 

wow now we resort to name calling huh Grow Up really...SHOW ME PROOF simple as that you cant and never will be able to you know why they are grounding wires understand that concept!!

I don't know why this is such a hard concept. The existing ground system in a properly working car has a resistance of almost zero ohms. Very little battery voltage is dropped across the ground system. By installing more grounding wires in parallel with the existing wiring, the resistance is reduced even closer to zero ohms. Consequently, whatever miniscule voltage was 'wasted' across the ground system, is now reduced even further. Per Ohm's law, the higher the current draw by the load, the more voltage will be dropped across the ground, all else being equal. That's why a good ground is essential for high amperage stereo systems and lights. However, other electrical and electronics systems typically don't care if they have 12.6 or 11.6 volts, and a good ground may make a difference of a few millivolts (1/1000 of a volt). A good ground DOES apply the full battery voltage to the load, and reduces wasted power, but it will NOT reduce the load on the battery. You will not notice the difference, and your car won't idle better, the tranny won't shift quicker, nor will the car make more power. If you like the looks, go for it. If you think it helped your car, get two of them.<!-- google_ad_section_end -->
can you understand that..it will no way shape or from control the ecu to tell the transmisson to shift any faster..why is this hard to understand!!!

 

chuckie311, I think more of what happens with the grounding kit install is it's "fixing" an inherent issue with the car in regards to proper grounds, which does have an impact on the performance of the automatic transmission.

It's been noted by many owners after grounding kit installations that the transmission response and shift times are improved.

It will also aide in an aging vehicle to keep ground connections in tact, and ensure efficiency within the electrical system. Dirt and grime over years can have an impact on performance, this is an easy step to remove that concern.

 

I did not say it will control or change the ECU. I was giving an example that the ECU is not changed or reprogrammed,etc. rather that the possibility of the "faster shifts" is the result of a cleaner, or faster transfer of the signal due to less interference or stray voltage. Some grounds are from one 14ga+ wire to another, and so on and can add up to a decent distance before they are actually grounded to the chassis. The grounding wires help to shorten the path and load. I agree that most grounding kits are well beyond what everyone will ever need (4 ga.) but I'm sure that is the aesthetics part of it and for the few with crazy audio systems.

I don't know why your so closed minded about the subject. I will tell you I don't even have a grounding kit, but grasp the concept and you can't ignore the 100s of reviews that all believe the shifting is improved. I also am realistic and agree that a lot of the other claims are unlikely, probably imagined due to hype, and some others are results of ECU resets due to the battery being disconnected. BUT the constant here are the transmission improvements on ATs - with some of the reviews coming from knowledgeable full out car guys, not teenage tuner punks.

For scientific sake, I would LOVE to see someone do some sort of dyno, or way to get precise info on the transmission shifts on back to back runs with and without the grounding kit.

 

Can we please not get into a debate on this DIY thread I created? If you think grounding kits are crap, cool, then don't make or install one. If you want one, now you have the steps to make and install it. Simple as that.

 

Thanks for this thread.

Although I am not fabricating my own (I purchased the BB pre-made set), the off-topic dialog confirmed that, for shifts alone this would be a valid install.

Nicely explained and compiled for those who have the inclination.

thanks!

So does it, or does it not reduce the high pitched whine that comes through the speakers when the stereo is off? If yes, can I just change that one wire? If so, which wire is it. I'm not much of a music person, so I listen to the engine alot, but that noise coming through the speakers pisses me off! Thanx
I have an '08 G37S coupe

 

PM replied ^^^^

 

Thanks for the great write-up. In the end, I changed a few contact locations with this and ended up making an extra 1ft single wire just for the drivers TB. I guess I kinda combined this write-up with Black Betty's to get the best of both worlds.

Your directions were very easy to follow....and i was truly skeptical about the results of this mod until I tried it and FELT how much smoother the car shifts and how much faster the triptronic response is.

Thanks again for a great write-up.

 

Thank you very much! I've been waiting for someone to post the proper/required lengths. Such an easy, inexpensive project!

 

No problem guys!

 

Have you even tried out the Grounding kit? If not then how can you say it doesn't work?


Exactly what he said. My friend had a 08 g37s 5AT and when I first drove the car it did not have any grounding wires (aka kit) and saw a lot of lag between the shifting of gears but when she got the black betty ground kit it made a lot of difference. I saw the throttle response was a lot better.

Also many people didn't know that it also helps with 6mt also. If you haven't noticed 6mt have a slight lag to them also and tested out the grounding wires and I am going to get one for the 6mt.

To bad black betty doesn't sell them anymore =(.

 

About how much does this end up costing? I have no idea what the price on the wire is
