Default Ultimate tuning and performance
hahahahaha
Egay is a joke


Guy talked my buddy into buying one these things off ebay.

Name: 17d98ee2.jpg Views: 1380 Size: 88.5 KB



So he buys it and puts it on. I get a text message yesterday and he says his truck wont idle good.
So he rides down and hooked my laptop to it.

He tells me about this lil contraption so i took it off and truck still dont wanna idle right.

Got my meter out and tested it, haha yea, talk about a rip. $30 down the drain.
Opened it up and this is what i find.

Its a a 16 pin Dip. 39K ohms Resistor. Wires soldered to pins 1 and 16. cant find a value for what it should be. kinda curious as to what his rip off is suppose to read and trick the PCM into what IAT reading.

i tried testing it and it read 35 ohms one time but couldnt get a reading again.
So basically $30 got him a cool lil black box with 2 wires, and a DIP resistor in epoxy with awesome sticker..



2 minutes of looking online and what do ya know!!!!

I called Bourns since they are the Manufacture of the DIP..

39 ohms is what it should read. Anybody know what Temperature that should be on our IATs?

Do you mean 39 ohms or 39000 ohms as originally stated? Makes more sense being 39K as it would trick the PCM into thinking it's constantly around -12 or so. Still utterly useless in the grand scheme but a great way to scam people out of money, lol.

would have been better off with just a potentiometer and 5 feet of wire.

Woops. Yea i meant 39k. Kinda forgot to put the k.

I unplugged the IAT out of my manifold and put the wires in the connector. It read -14*. Looks like it would Add 4* timing?

It would add 4* of timing, pour in the fuel and then set a rich code on down the line.
