It's probably just a resistor you add to the intake air temp signal to fool the ECU into seeing a certain value.

I wouldn't try it .

The idea does have some merit, but it would be a pretty big project to find the right value for optimum power and safety, and it's probably relatively easy to pop a motor messing with it.

Regardless, it's probably 30 cents of electronics - most likely a resistor you crimp onto the intake air temp wire with a ground lead or something similar.

Thats exactly what it is, supposedly it tricks the ECU into thinking that there is COLD air coming in, so it advances the timing...I could do that my damn self by manually advancing.

I was just poking around Ebay, and wondered if anyone had any pros/cons to this. 20hps for $1.50 is an amazing mod, if its as good as they say it is. But it sounds too good to be true.

Anyone else mess with this?

Skip this. You can do the same mod without any installation. Just go out and adjust the CAS timing. Set the timing to 6-8 degrees of advance.

On an 88 NA, 8 degrees of advance showed a 6 RWHP gain on the dyno. This is about a 5% gain in HP at the flywheel.

Thats what I figured, I was just wondering if anyone bit on this little gimmick...Looks like everyone is a little smarter then that.

They probably send you a screwdriver to open up the CAS...

It's ebay, just look at that turbo-charger boat exhaust fan I posted previously, obviously they exagerate numbers a little bit TOO much, not to mention will say anything to sell something that cost $.25 to make

i remember a post on here a while back, you can go to radio shack and buy like a 1.00$ resistor and put it on the Air temp sensor line and it makes the ECU think the temp is 25 degrees cooler

Ive tried that. It doesnt make the car run better. In addition to advancing the timing, it adds more fuel too. So you end up running even more rich than before. Dont do it, youre wasting time and gas. Just get the 10 mm socket out, loosen up the CAS, and turn it some to advance the timing.

I cant believe anyone here still thinks they can actually get HP stuff off of ebay.
