When I did it, I originally grounded to the chassis where the battery ground leads to... after about a week my battery bursted with battery acid everywhere.


I thus re-wired it to the negative battery terminal. Then I noticed that my a/c light flickers and wanes in and out at times and sometimes turns off by itself... I did notice a difference when I first put it on, but the symptoms I get may not be worth it for me. I've had it on for over a year now.

Either you did something wrong (cant imagine how, worlds easiest mod) or you're having completely unrelated things go wrong out of pure coincidence.
Connecting your TB to your chassis CANNOT cause any of the things you're describing.

I did the advanced timing mod, it was a huge difference, but not necessarily for the better. Yes, the revs were noticeably snappier/more responsive/faster, but at the cost of torque... let me explain, normally when going up a hill I can steadily hold my foot on the pedal and I'll maintain my speed.. but after doing it, I noticeably was loosing speed on my same routes... so I would have to floor it to maintain my speed... weird phenomenon, but logical... as it advances your firing(not complete combustion.... My gas mileage after a few months was noticeably worse(a lot worse actually, I could not get more than 29-30mpg on the same routes I've been taking for years) and I just got annoyed so about a year ago I moved it back, but slightly more than stock... gas mileage has noticeably improved(33-34 on the same routes).

Yeah I tried the advanced timing mod recently and switched it back after about a week. The car seemed to run like crap with it (and 91 octane), even after an ECU reset and 75 miles. The engine just didn't seem to be happy. The power was lurchy and not noticeably increased outside of those lurches, and my gas mileage was horrible (15-16 MPG).

I'd love to know how people are getting such great gas mileage in general compared to me though. I'm averaging anywhere from 22-26 MPG with 60-70% highway driving, and this is with a 2.0 (ATX). Granted, I do have a lead foot...

That's really low man. My wife's 2.0 atx makes at least 30 or better on the highway. I'm seeing 31-33 on the highway with my 2.3L manual. Call me surprised after my 2.3 Auto used to make 29 mpg highway.

Thanks man, I'll get it checked out by my mechanic I guess.

You shouldn't be surprised by better gas mileage in a manual though, they're supposed to get better gas mileage. :grin:

From 28-29 to 31-33, I didn't expect that much difference.

so annoying

Alright, I'm new to the whole DIY car mod world, so I thought I'd start with something easy, which apparently this is. However, I can't even get the nuts loose to view my battery, let alone attach wires to anything. Everything seems to require heavy duty tools. How is everyone else doing this so easily?! :huh:

 

[ultimica06]

Update on my car after doing this..

I felt a difference right after I did it....After a while it went back to how it was before...SO longevity of this Mod doesnt work.

What year is your car? You don't need any tools to get to the battery. What is your definition of a heavy duty tool?

 

[nathan_reznor]

I have a 2006. I tried a bunch of wrenches, but they all just slip off and strip the nut because I have to turn them with so much force.

All you need is a 8mm and 10mm socket to do this. You might need an extension for the throttle body bolt too. Also you should use a 6 point socket to avoid rounding off the bolts.

Thank you. I'll try to find some metric tools.

stupid question I did this to my mz3 and felt a noticeable differents when shifting. well now my girl friend is wondering if i can do it to here mz2 which is an automatic... so basically my question is can this be done to an automatic and will it even do anything.

Thanks guys

 

[Cab0oze]

It probably does more for an auto than a manual so yes. As far as doing it on a mazda2, well I haven't checked out the engine bay to see how well it is grounded as is. Either way though, can't hurt to try. Worst case is it does nothing.

 

[Chaury08]

Thank you cab0oze. I'm new to all of this still. But I will try it out.

 

[ultimica06]

Still doesnt do nothing.....I was sad.

 

[itstillruns]

for what its worth grounding the tb did nothing for me but using a buddy club condenser made a difference

 

[Cab0oze]

Buddy club condenser is overpriced. For what it does, it should be worth 30 bucks tops.

 

[ibob991]

I used the grounding kit found at flex innovations on a ATX 2006 mazda3 I and what a difference in the throttle response!

I followed their diagram props to them and used up my old sub wires I think it's placebo effect bro. But more grounding as long as it's done right can't hurt. I think it may help as the ITB is plastic and there has to be a static charge built up through that *THING*

 

[leshan]

I just checked resistance between throttle body and grounding on the car with a multimeter. It's about 7k Ohm. Should I order a cable to ground it.?

Thanks.
