Mazda 3 THROTTLE BODY Ground! | EASY Throttle Response MOD 🔥 

Nice!

What? 😂

bro?? lmfao

Last post this guy ever made

Thank you, I am looking forward to re-making a few! On the other hand, when I get an actual stereo then I will be doing a rear view install :)

😊

Yes sir!

It's a crimper. Dudes just using it properly. And not using 10 cent connectors.

Glad it worked!

Hey I have a 2009 Mazda 5 and I've been on the forums searching for some other things (motor mounts, sway bar links, etc) and came across someone mentioning a throttle body mod but couldn't find anything specific to the Mazda 5. Any chance you have any links to any forums about this specifically for the 5??

@@jonathangaliano2617 It's the same process as it's the same engine.

Cheers

Soldered?

Assaulted?

Glad to hear!

I’ve got an 09 3 too does this help with the massive delay when flooring it? (I’m assuming it does but wanted to ask someone w same car)

Glad it worked for you!

@@ColtonRichter did you connect it to the positive or negative

@@NWA8000 negative don’t do positive 😂

Glad it worked!

Hwy Shane, How noticeable of an improvement do you find this to be, have a 2006 Mazda3 2.0 sport, 👌

@@phil3038 It’s not a power mod by any means, but the throttle response is very quick compared to the stock feel. It’s pretty snappy off of stop lights

@@shanepressley831 thanks for the reply, sounds well worth it, 👍

Glad it worked!

i mean you realize what a hog those vehicle have become safety this safety that I think some of the new camaros tip the scales around 4 thousand pounds that is almost the weight of my yukon

@@D3AThCAl2DS yup your right 4000 Camaro wow now wonder she look like a big girl 😂😂😂😂

@@D3AThCAl2DS I was wondering why my Mazda 3 six speed had a awfull take off. 🤦‍♂️

I did it,I think I felt a difference on response I’ll see on tomorrow’s ride.

I just did this to my Mazda 5, and it really helped with throttle response to the point that shifting is much faster and smoother and starting from a stop is a lot more easy and consistent. I'm used to driving cars that have cables run directly to the throttle body (and apparently cars that just do DBW right). It doesn't make the car any faster though outside of that. What kind of slow ass Camaros and Mustangs are you racing? Were they actually trying? I know my 5 will still not hold a candle to my 4G Eclipse GT and there are a lot faster cars out there than that.

what did you notice ?

Hey bro I definitely noticed a difference in throttle response it seemed a fraction of a second faster a bit snappier on the shift points

Now time to try this on my 3.0 mazda6 s

Good luck

I got a Mazda 3 2015 2.0 isport, did yours work?

Yes sir!

I just did this to my 5 yesterday. I used a 6 gauge ground cable that was probably meant for a lawnmower. $8 at Fleet Farm. A tiny bit long, but not by a lot. It definitely made the throttle response almost indistinguishable from a car with a cable instead of DBW. I used to think the trash throttle response was the clutch just being totally worn out or excessive carbon buildup, etc. With a stick shift, it is so much faster and smoother to start in 1st and shift between gears. Probably putting a lot less wear on the clutch now. If you have not already, do it.

Thank you my friend, glad you had good results! It's something to do with ohms & all that jazz, not being grounded out completely or something... doesn't make sense but there is a logical theory to how it works!

@@ColtonRichter the gasket prevents the TB mating surface from complete contact with the engine for grounding, so the electrical pixies can’t move as easily as they do with this mod, so the motor controlling the throttle plate doesn’t work like it should. I bet this mod makes the throttle body motor actuator last longer.

Cause DC flows from - to +, since the whole body of a car is -, so it acts a bit like a resistor, it takes few ms to flow the electrons, if you use a direct connection, the electrons have less resistance to "fight"so that's why the electronic switches or reacts faster, according to the comments it does make a noticable difference..

@@duc696monster6 nailed it.

Assuming it works the way it's described in the video (I don't have a Mazda myself so can't speak from any first-hand with-or-without testing), it sounds like Mazda engineers didn't allow a strong enough ground path in the design for the throttle body's electrical circuit. Toyota was notorious for also under-sizing wires in the electrical for their vehicles in the late 80s and well into the 90s. From watching the video, what I gather is that the positive lead to the throttle body is sufficient, but due to an undersized (or poor connection design) ground lead, too much resistance is introduced into the circuit and not allowing enough current to actuate the butterfly valve as quickly as it could be. Adding the secondary ground is providing enough of a ground path to allow enough current through the entire circuit to more quickly actuate the valve. With electrical systems, the point of the highest electrical resistance is what dictates how much power can travel through the circuit. Much the same was as a chain is only as strong as its weakest link. I'm curious to see now if the issue is the same in the Mazda 6 with the V6, since my GF has one. I've been planning to do the "big 3" electrical upgrade on it that I do on all my vehicles, and will likely do this as well.

Nice!

According to the previous owner, it's been on for about 3 years. Bank 1 o2 sensor is toast haha

@@ColtonRichter oh gotcha! Nothing I know how to fix then haha. But honestly if it doesn't stop you from driving it, it's not worth fixing lol.

I notice its impact and i'll replace it one day, just not a worry on my mind right now!

@@ColtonRichter thats funny my check engine light just started to light up for the exact same reason

It's common!

Great to hear!

Not sure man, doesn't hurt to potentially try?

Because it doesn't do anything..placebo

Most definitely.

What makes sense to me about this mod- is adding the extra ground wire to Batt. negative or alternator case, is creating a parallel circuit to the factory harness ground. So, even if zero Ohms are measured from TB to batt. negative terminal, this reinforces the grounding, and might even create Negative resistance. Good grounds are Uber important!!

The things he puts on the end of the wire are called terminals, of which there are many types. The type he used is one of the most common types. The size needs to be appropriate. The wire size is given as 8 gauge. Gauge is a wire measurement based on the thickness. Higher numbers are thinner, lower is thicker. 8 gauge wire is pretty thick. Thicker wires can carry more electric current, in general.

Not sure, wouldn't hurt to try!

I haven't painted my glove box handle

Awesome, glad it worked out for you!

It would most likely, 2nd gen platform between 2.3 and 2.5 is pretty much the same, 2L and under wouldn't be the same only difference is whats in your engine bay

Sub wire can come in 8 gauge, so make sure it's 8 gauge. Try it though, doesn't hurt!

Thanks guys 👍🏼🤙🏼

Doesn''t hurt to try, as long as it isn't cable fed

Automatic works yes, I prefer the battery but fender should work too?

It shouldn't matter, it just looks cleaner and we have proof of that specific one working

I've only ever seen people do it to the one I did, better safe then sorry!

@@ColtonRichter the upper right one?

@@not-AI Correct

Does this work on a 2014 manual 3 gt?

Yes

@@ColtonRichter sounds good and appreciate it so much for the car content 🤙🏽

Definitely not related to this unless you seriously wired something wrong lol

Yep!

Wouldn't do anything more

Good tip!

Haha nice bro!

I do not believe so, however... 04-06 throttle body's are bigger then 07-09!

It takes 5 minutes so why not

no it does not, k&n makes one and they are a quality brand but check out redline360.com

Go to CarID.com and see what fits your car.

@@ColtonRichter facts

The main battery :)

@@ColtonRichter Thanks, it works.

@@dejankrstin2019 hi please confirm if yours is the 2.0 litre version. My car has two batteries too

Any luck? Mine is a 2013 CX5 2.0 and the sluggishness is making me replace all kinds of parts. Im going insane

I believe so yes!

No

Local hardware store :)

Should be avail. At home depots, rona, lowes.

I've heard 10AWG works, 12 might be to thin.

Unattach battery, hold horn to drain, re-attach terminal to battery, start car and let idle for 10 minutes.

@@ColtonRichter Really thats it?

Yes sir!

Still doable with an intake. Deadass go to your generic hardware store and look or ask for 8AWG wire.

@@ColtonRichter what size are the wire connectors ?

Same size as the wires

Tried & proven with battery, i'll stick with that.

Yes.

Yeah!

I heard Speed's already have this done in the harness, I could be wrong. Update when you done!

@@ColtonRichter yes I really didn't feel much difference. Owell pretty easy lol

Not sure, it might already be done from factory.
