I'm in the process of making a ground kit for my 2G and am wondering if there are any points I can include so the ECU is grounded better. Any ideas?

If you don't know where to ground it to improve the ECU ground, what makes you think it needs improving?

Uhhhm. . . . if I *KNEW* where to ground it . . . don't you think this thread wouldn't exist?

So you were able to read the first half of my question, VERY GOOD! Now go back and read the second half, where I said "what makes you think it needs improving?"

If you want to make the ECU grounds as strong as possible, cut a hole in your firewall, and run a 0 gauge cable from the battery, to the ECU. Thats the location you are asking about, but what makes you think you need this?

Brad

Yeah the ECU shouldn't need a better ground. If Mitsubishi thought it needed it, they would have invented it. Just grounding engine components should be enough. AC generator, clutch housing, engine block, and fuel rail should be a few things. It doesn't really need it but I guess its been proven to help like 5hp maybe. Butt dyno cant pick it up, but that isn't very accurate either. I grounded my engine a bit more, but I also have my battery in my trunk.

so aside from what's in here . . . http://www.dsmtuners.com/forums/showthread.php?s=&threadid=75889

pretty much the only other thing I should consider grounding would be the fuel rail?

Yep, if you don't ground the fuel rail properly, the fuel gets ionized the wrong way, which drastically hurt combustion efficiency. I recommend ground straps at both ends, AND magnets as well, to keep fuel ionization to a minimum. This makes the fuel burn that much cleaner and quicker.

You mean those fuel line magnets 'as seen on tv' ?

Define "this"? If you mean this whole thread, yes it got turned into a joke when people ignore common sense, can't answer simple questions like "what makes you think the grounds need improving?", state that its been "proven to help like 5hp maybe", talk about grounding the fuel rail, and ask questions like this even though there are tons of other threads on ground wires out there. The magnets are just my attempt at fitting in with the brain dead posters here

Probably because he saw a few articles in the mags showing how you can get 5-10hp from adding all sorts of different grounds.

I do not know what to think of that entire things. It appears to be more of a hype... But some people are getting “some” improvements...

I would like to see one of the DSM shops do a similar test. Look at it this way: how many people loose one (or more) different ground point while modifying their cars? Almost all of us have taken off the down pipe ground... So maybe returning it to sock might yeild couple of hp.

Or, how many of you guys drove around with ECU laying on the passenger carpet, not grounded at all? I know I have many times, and I have never noticed any ill effects...

I couldn’t even begin to answer this question, nor am I sure that there is a proper answer to this question.

Just because some people are showing some improvements on a dyno, doesn't mean a thing. I see that all the time. Its called the "I bought a $20k dyno, but didn't learn how to use it to get repeatable results" syndrome.

I know what to think of the entire thing. I cornered the people who make/sell the most popular brand of ground wires at SEMA. I asked them several basic questions. Things you should know if you make ground wires. Even their Japanese "engineer" could not tell me the resistance of their ground wires. How can you tell me that these wires are going to be better than stock, if you don't even know the resistance??? It would take a lot more than knowing that to convince me it was better. But at the very least a real engineer would know the resistance of the wires as the VERY first thing.

That IS an issue. People should try to make sure their ground points are clean and all there. But thats should be a separate issue, and much cheaper to fix, since you just have to bolt things together right. If you aren't competent enough to put the stock grounds back, how can you be sure you won't do the same with the aftermarket grounds?

You make 2 wrong assumptions there:

1) That because the ECU case isn't bolted down, the rest of the ECU isn't grounded. There are several ground wires in the harness to the ECU. This ground is used for all of the components inside the ECU. So the ECU is still grounded properly, even though its not bolted down.

2) That the ECU case isn't grounded at all, just because its not bolted down. The case ground is run through a small capacitor to the main ground in the ECU. This is pretty standard in isolating ground planes. This is the way it is on 2Gs, and I'd bet its similar on a 1G.

This grounding kit is a huge gimmick. I have yet to ever see any amount of proof saying they do a thing. Only claims and bad opinions.

Only thing they do is correct for stock failing wiring. If your stock wiring is fine, there is no need for this dumb mod.

Sure import tuners did a dyno test on it, yap yap. Remeber, the car they dyno tuned also caught fire just previous to the dyno runs. Makes you wonder about that wiring huh.

When people say "it improves spark", i just want to jump through the monitor and kick the person. I mean, come on. When someone puts a MSD ignition on a mildly tuned car (most these grounding kits are falling on mildly modded cars), no real power is gained. At least not enough to speak about. Perhaps like 4 hp or something dumb.

I donno, im just lost for words now, i just have too many comments on this topic. Basically ill try to leave it at this: dont say they do anything unless you have proof. proof isnt from a vendor or manufactuer dynoing of course. If you say something like "but i definatly noticed a difference", ill just forward you to a google site about figments of imaginations.

Lata.
