IAT Sensor - Resistor Mod

[SilverBullet75]

Hi,

I heard about some little black box that you can buy from Ebay for about $20 that increases HP and gas mileage, etc... A local VX owner (not a member) said he has it and it works. I'm thinking BS...
So I start researching this thing and found out that it's just a project box with wires coming out that go to a resistor inside. Clever.

Then, I found a site (below) that describes how to do it on a '99 LS1.

All it does is bypass the Intake Air Temperature sensor and tricks the computer into thinking that the intake air is 57 degrees. This causes the computer to change it's parameters, advancing timing, etc.

So, I went to Radio Shack yesterday and bought the resistor (pack of 6, I think, for less than $2.).
Installed it in about 60 seconds.

Prior to installing, I've been having sluggish performance due to 100+ degree temps outside.
I drove it around the block, and had NOTICEABLE performance gains... but, with great power comes great responsibility... LOL
I did hear what sounded like light pinging from the advanced timing.

This morning's trip to work was great though (at 80 degrees). Strong performance.

I will be tracking this very closely on my way home tonight, at 4pm, during the hottest time of day.

NOTE: Las Vegas is at about 105 degrees these days. This mod works for hotter temp regions... colder, not so much.

Before anyone says... "there's a reason why the computer retards the timing in hotter temps"... I know this. That's not the point... I'm testing the "myth" of the Resistor Trick on the VX.

Hoping for the best!
JIM
