Tried the "Mazda" 2.3 TB grounding mod tonight...

Many Mazda 3 owners (as well as some others with drive-by-wire throttle controls) have been running an electrical wire from their throttle body to the negative terminal of the battery. This mod is quite popular amongst the 2.3 Mazda crowd - claims of smoother power delivery are everywhere. Well, I tried it tonight and it made absolutely no difference in my car. I really didn't expect it to, but it is a 2 mintute mod so I thought I would give it a whirl. But my throttle response is almost instantaneous now since I am SCT tuned, so perhaps it might make a difference on a stock car. At any rate, it seems that the Mazda folks with the 2.3 have had some problems with their ECU calibrations and this mod helps in some cases.

how has this worked out? i wanna try it on my 4-cyl auto
i did the mod on my 4-cyl auto and call me mental, but i feel like the gears shift smoother and the response when i push the pedal is quicker. especially when i'm doing about 25-30 and i stomp the pedal, i don't get that kick when the car revs high. nice and smooth. maybe it's just me...
yeah, when you hit the pedal, i guess the car downshifts and revs up. i used to get a little jolt when it would do that. just a kick.
