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.
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...
