You only need to do this mod if your measuring more than .009mv on the ground wire if you dont have more than that you won't see any improvemt.

Yes ur correct basically the more voltage you got the worse it is, you probably wont see a huge difference unless the voltage is a substancial amount like like atleast aorund ~.03mv most tcars I have regrounded that were bad had around ~.04mv

Yeah, after my swap, my car has been very jittery when accelerating.

I remember someone talking about a good spot to ground the wire besides where he grounded his...anybody remember?

I did this mod 8 years ago. Gotta check and see if my ground is still good. My MAF keeps going bad!

Ok, I just ended up wiring in a whole new connector due to loose pin tension, I added on an extra ground going to the intake manifold, soldered and heat shrinked all connections, and when i plugged it in and turned the key on I get 1.3 volts to eh power wire, 0 to the signal, the signal has .2 ohms to ground, the ground has the same, and the power wire has 2.5k to ground, and it doesnt run, so since I had another ecu laying around, I cut the power wire and took off the extra ground just to be safe, and now I have battery voltage to the power wire, but I havent hooked it all back up yet fearing that I will fry an ecu, could that sheilding have anything to do with it, or did i screw up in another way? I checked the wires to and they are wired in right, im so lost on this, any help please

So did you slide both male connectors into the single female connector? I'm going to pick up the stuff in a little bit. Just curious. I take it you don't need the stock ground unless you are worried, correct?

I would guess that the reason is because the MAF measurements may not be accurate with a bad ground. If this happens, the A/F mixture may not be calculated correctly by the ECM.

The reason for the two female connectors was just incase nothing worked out you could just re attach like as if it was stock. Just incase say..... you fray the inside of the wireing hose or something of that sort. Just a fail safe that's all. Not really nesscery but did it just for this fact.

See post #38. More or less the exact reason. Connections will corrode and amps will fade. This is pretty much a better way to keep a good/better currect.
