VSA Bypass resisors?
Anyone know how to bypass VSA using resistors? I have seen the post before, but I can't find it through the search button. VSA is really starting to annoy me, since I modded the egr pcv systems.

youll make three wires come to gether in the center like the end of a fork with the center being a plain wire ... one resistor will be 3K ohm the 8K if i remember...ill search my PM's and emails to make sure

You need a 8K resistor and a 2K resistor. The 8K resistor goes between the center pin and gnd. The 2K resistor goes between the center pin and VCC. This is on the sensor.
On the motor-side, just put a 10W 3-ohm resistor between the two pins.
Now... if you do plan on racing... turn the VSA off by pushing the button because I am not sure what happens if the VSA tries to do its thing!

Would this be dangerous while under boost to loose fuel?

You could use the 9K and 1K. Essentially that puts the sensor voltage to be 4.5V. The sensor expects ~3.7V... the 8K-2K combo achieves 4V. 4.5V is okay.

[QUOTE=typeR...another easy way to do this is just leave the VSA body in the engine bay still connected to its harness...[/QUOTE]
That's a good idea. Would cut back on some resistance to air flow too.

guys, this might sound noob but when taking off the vsa throttle body, what do i do with the two hoses connected to it? I'm pretty sure I can't just leave them hanging there correct? Thanks guys

On a similar note, what if I just removed the VSA unit, I assume the light would stay on but would this cause the same reaction as if the VSA button was not turned off and the unit was removed and resistors were in place? Or would it just act as if the VSA was turned off and cause me to almost die when I burnout? I definitely do not mind the light being on if that was the case and not have to worry about turning it off and on all the time.

you will need to use the resistors or else your car will all but stall.
as for the coolant lines. i'm just going to put a hose from the 2 points on the block that they go to. after looking at it more and more, i feel the vsa is a major source of restriction. not only is it blocking flow, but those coolant lines can get pretty hot and heat up the IAT. i have a pre-dyno and will be doing a post dyno as soon as comptech gets me the stuff.

I noticed the same exact thing. Hope the dyno shows something!

FYI
I removed the VSA unit tonight and put a 8" x 3" hose in the gap. I did NOT put the resistors on yet and the car runs OK but not perfect. The VSA and ! lights were both on. I caused wheel spin and it worked OK (held the burnout) again, but not it's usual self. The car feels like the PCV hose is pinched. Just a little sluggish all around. Another thing I noticed was that my fuel pressure was a few PSI lower than usual. Normal is like 37-39 PSI or so, but after doing this, it was all the way down to 34-35 at idle.
Does this give anyone enough information now to explain what the ECU does when the VSA is not connected and resistors not soldered in?

Where exactly are you placing the resistors? a bit confused on how to wire them, also does this need to be done using a soldering iron? the links to radioshack show a different resistor than you mentioned.
