15+ hp for only $5.99???

Hey everyone, came across this on ebay:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2962619311&category=1469

Supposidly this mod-chip tells the jeeps computer its recieving colder air which modifies the air/fuel ratio....sounds promising...but its really really cheap.....anyone think this thing would actually give you 15 extra horsepower without affecting your mpg's?

"Instead of replacing your computer or a chip in your computer our mod replaces a sensor that tells your computer you car or truck is taking in colder air. This in turn adjust your air/fuel ratio slightly and frees up HP ."

what "sensor" are they referring to? i dont know about replacing a sensor for no reason?!

it is a rip off ithey simply send you a resistor from radio shack .15 cents

If it seems to good to be true it most likely is! tug

Pretty fishy to begin with since there is no pic of the item for sale, unless they are selling that streetrod for that price :shock:

I think the resistor was placed on the MAP sensor, but I'm not sure. I remember seeing this scam in the past.

www.madxj.com has a write up on the adjustable MAP sensor, have also heard tell of a resistor (100 ohm) in the engine temp. sensor. Both richen up the motor a bit (more gas). If your looking for power, the high flow intake and a bored out throttle body seem to be the largest HP gains , that won´t mess with your mileage, as long as you keep your foot out of the pedal. The throttle body on the Renix XJ´s and some of the mid series XJ´s (91-95) have a restrictor cone built (casted) into the throttle body, that´s pretty easy to bore out and opening/grinding out the inlet for the intake manifold a bit. It´s been said, boring out the throttle body/intake has actually increased mileage a bit, in conjunction with a high flow air filter. Could mess with low end torque a bit, but the 4.0 has low end troque to spare anyway.

Check his feedback! he is making some money on this!

HERE'S some more light reading on this scam.

Actually the sensor it "replaces" is most likely the MAT (Mass Air Temperature) Sensor.

I too believe this won't do any good. You can't screw with a sensor and expect the Jeep to run correctly after wards.

Besides, they don't even show a picture of the "modification" they're selling you :shock:
