Throttle Body Ground (by loudboxer)

I've been following this thread.. I have a mazda5
one weekend I had some time and did some testing.

1. Tools used. Synchro scope. I wanted to 'probe' what is
in that electrically floating 'Throttle body assembly. With Engine Idling.

2. Here is the waveform I got on the Throttle body.
Notice the 'cyclic' glitch or spike. very low about -10mv.. only.

3. Then I decided to connect the throttle body to ground.
and the waveform I got is.

I think they build the cars as it is and then
adjust the programming to tolerate these spikes.

As for the 'effect' of throttle body grounding..
-- before the throttlebody was grounded, the gas pedal is a bit 'loose'.
You can press a little bit and have to wait a while then the car goes.
It will 'slingshot' the car forward.

-- After the throttle is grounded, the feeling is like having your foot
against a wall, you push and the car moves. Just like the ordinary
cars.

I'm still not decided which one I prefer. I sort of like the
original feel.. that is without the grounding.

Sweet, thanks for testing that. Good to visually see a difference and not just a butt dyno "I think i feel a difference".

That is actually quite interesting, and isn't science fun? Thanks sky hawk!

ok, the ground kit works, however, on MZ3 and MS3 I would suggest use 5 grounding points, detail on this link:http://www.flex-innovations.com/mz3_instruct.htm

I am not trying to sell anything here, I did my own grounding kit, with 8AWG wires, it works, and I Used that guide to make my own, just make sure the wire can resist heat

 

[ericrapp]

After reading many conflicting reports in regard to the tb ground and just having read the link you provided, i was wondering. What advantage specifically do these popular kits provide? It does appear to be a quality manufacture with good detail. Thanks

Hopefully this thread is still alive. I'm kinda getting interested in this mod...

1. Is there a significant improvement using the 5-wire kit than the single wire thebeansoldier did?

2. for the single wire ground, how long does the wire have to be installed clean?

thanks

I just did the mod on my 3 (2007, AT, 5 door). I'm not convinced there's an impact. The only thing I noticed was that downshifts from 5th to 2nd are instantaneous when I bury the pedal. I THINK this is a change (improvement), but I'm not convinced.

Anyone else done this mod recently?

cheers,

If this mod is done at the same time as the tinfoil hat mod you get incredible improvement, make sure to use 8 guage wire and 6 guage tinfoil.

Do you have a link for the tin foil hat mod?

From what we have read it may not be worth the effort in this application. But that is just an opinion.

After driving around a few days with the mod, I can state with confidence that there is no discernable difference in engine or transmission performance.

I hereby debunk the efficacy of the TB ground mod for the 2007 Mazda3 AT 2.3 liter engine.

well depends if any corrosion
has a cured on the engine so i would say case by case may be no diff on some car's but ive seen tuns of vehicles that had lost ground due to the elements and causes all sorts of problems

 

[05maz3subd]

you guys should do an entire ground instead of just one wire i just did it this weekend and i can feel the amount of change. I did the 5 wire grounding and it give me response alot better, i can actually accelerate in 4th and 5th gear, without going 80+ mph. I also used 10 awg instead of 8 cuz no automotive stores carry any more then black, so i used orange wiring to match the engine bay and body color.

 

[georgecastaneda]

hey guys will that work on my 2000 protrege ES?

thanks

Where do you buy the parts for
10gauge 1/4" ring terminals
and 10gauge wire

and approximate cost?

let me know, thanks

QUOTE=thebeansoldier;2413770]All it does is decrease the throttle tip-in delay, provide a more linear acceleration give you smoother shifts. ATX owners report the most "gains".[/QUOTE]

 

[1nmhbacky]

If you have an ETB, you can do it.

what is ETB
sorry noob question

 

[Jdm_Mica]

electronic throttle body

most cars prior to 2000? were drive by wire throttle

 

[1nmhbacky]

I just did this with 10awg cables from Home Depot and 1/4" covers

I guess on my ATX mazda 3, the acceleration is a bit smoother
if i tap the gas a bit, while coasting on 4, it drops down to gear 2 faster than before.

very small change. It very could be snake oil. LOL

(drunk)

you mean, the opposite?
Or by "Drive by wire" you mean cable driven!
