not even worth making

 

I heard they run alot smoother with those grounding kits?

 

Did you hear it from the guy whos selling em?

 

if your car has grounding issues, it might make a difference. some swear by them, others despise them and anyone related to them.

i havent thought about it for the STi, but Do know that if you wanna try it, make sure to fully understand what grounds to use, and where.

ese

 

i know when i put a grounding kit on the wrx it helped, but on evan's old sti it did nothing.

so i dont know what it would do on your car john you have wrx grounds on an sti turbo set up.

 

definately not worth paying for. i made one at work one day when i was bored and it was free. it didnt do anything.

 

FUtec2k said it made a difference for his Sti when he constructed one here:

The usefulness of grounding kits will vary depending on who you ask. It seems to vary on the car, and the sensitivity of your butt dyno. Naysayers will claim that the act of resetting the ECU by having the battery unhooked contributes to the effect of the car running smoother. Proponents will say it improves sensor readings, among other benefits. The theory makes sense to me, I'd more lean towards seeing a benefit from doing it, but again, it depends on the car. I'm going to do it to mine eventually because I suspect I have some possibly grounding issues I've noticed in my gauges recently (most notably the EGT gauge likes to fluctuate if I have the stereo up).

My advice: If you want to do it, buy the wire from a local stereo shoppe and build one yourself. Probably $20 in parts will do the same thing as a $100 kit bought from somewhere. Heck, Franklin might be able to get you the hook up at teh Circuit City.

BTW, that "voltage regulator" is probably just a big capacitor inside a case. Same difference.
