throttle body grounding mod
has anyone tried this yet? i have a friend with a mazda3 and lancer and did this mod to both of them. unfortunately its much easier to do if the battery isnt in the trunk, but im thinking maybe you can get the same effect using the jumper short cut battery under our hood.

i dont see how this could do anything, with my bit of electrical knowledge.
just ground it to the body or somthing, its the same exact thing
dont waste the wire goin all the way to the trunk

I'll probably either ground it at the engine block, or ground it where my nitrous solenoids are at.
The TB is grounded with a 16+ gauge wire, the point is to give it a larger ground
quoted from mazda site.
"All it does is decrease the throttle tip-in delay, provide a more linear acceleration give you smoother shifts."
definitely something that's worth a try.
but yeah it would be a bitch bringing that wire all the way to the trunk.

If anyone wanted, test it by doing immediate before-after, just disconnect the ground at the TB, try the car, then connect it and try it, see what you feel.
Also, I imagine it would do more on the 2.2/2.4, the SS/SC goes onto an all metal setup, there isn't a giant plastic manifold to insulate it. LSJ's are probably better grounded already. I might have to break out the OHM tester.

Same ****. Just compare your car to an SS/SC, from say the head to the TB. Your car should be open, SS/SC should be nice and low.
Then check for ground from the TB to the frame or something, same spot on both cars. Should be the same result from what I can think of.

Kay, I'll do the TB to the head, then from the TB to the Driver side strut tower bolt
First I'll do OHMs with the car off, then with the car running, then while the car is idling, I'll check voltage to see if there is any static charge at idle.
BRB with results.
on a side note i have had to ground monitors in cars because of the electric current they pickup through the other equipment, and shows up in the screen as waves. But thats not a static build issue...
hell try it would be interesting to see what happens. Although the basis of this theory is static effecting a servo...
Okay, this is interesting.
The casing of the throttlebody is not grounded at all.
I triple checked this.
And heres another weird but interesting thing, i checked the voltage difference from the throttlebody to the chassis in four different places and came up with a 0.3v (+/- .05v) difference in voltage
