performance chip installation?

Hi all, just got a nifty little 92 wrangler with a 2.5 engine. Runs great but could use about 10 more horses. Saw an ad for throttlemax performance chips on ebay that claimed hooking this up to your maf/iat sensor would do the trick. Hey, for less than 25 bucks, it might be a bargain. (or might be 25 bucks pissed away) Anyhoo, I bought one and it arrived yesterday. It's only about a couple of inches square and maybe 3/8" thick with two black wires coming from it, and an instruction manual that was about as vague as you can get.

My maf/iat has a 4 wire connector. Any ideas on which 2 wires the new chip should splice into? Also anybody have any experience, (or luck), with these gadgets?

Any help would be appreciated, and I'll be sure to post an update on ímproved performace". Thanks, g.

You can go to radio shack and purchase a resistor for 99 cents and hook it into your iat wiring and achieve the same result. Except for the 10 horsepower part... There is no majic computer chip that can give you any significant horsepower gains.

Bought a similar chip... Splices onto the IAT sensor. I have yet to find the one on my 2002 wrangler 4.0... Maybe, with some help, I could put it on my Jeep, and I can report back on if it actually does help at all?

The air temp sensor on my 92 is located on the left, (driver's side) of the engine and is connected to or adjacent to the ais motor at the intake manifold. The sensor has 2 wires: pin A brown w red stripe, and pin B tan with a blue stripe. Colors for your 2002 may be different. The instructions note not to cut the wires leading to the sensor, just splice into them.

Good luck and keep us posted, g

You will get less gas mileage, and gain no horsepower whatsoever. That's really all those chips do. It's a resistor that changes the signal output from the sensor to trick the computer into sending more gas into the engine.

Computer chips honestly only work on newer vehicles that have a very integrated computer system that controls every aspect of the engine.
