All vehicles have an Electronic Control Unit (ECU)-a computer chip that electronically manages and monitors your car's performance-that is made according to government regulations. That means that your car could be going a lot faster and getting more power if you replace the ECU. That could cost up to 2000 dollars. This mod will modify your stock ECU with a Zoom performance chip. This mod connects to the car's ECU by replacing the Intake Airflow Temperature (IAT) Sensor. Once the module is installed, the ECU will read that the air coming in through the intake is cold air; think of it as a "default" setting on the ECU. When the ECU reads this, it leans out the air/fuel mixture-in other words, it will take in more air, and then add more fuel to compensate for the extra air coming in, thus, producing more power and advancing timing 1 to 2 degrees. Because the engine is creating more power, give your Car or Truck up to 20 More Horsepower!
This performance chip will work with all models of the vechicle in the title as long as the vechicle is fuel injected

All that sounds like is a resistor that you put in the IAT sensor to make the sensor read wrong???

Right, think it's like 1 kohm? A $1.99 radio shack part.. Shy away from it..

No, no, no, no, no.....Only a ricer would fall for that one. Any reputable tuner will tell you that there is little to be gained from "tricking" the ECU with these little gizmos and others like them...and may even harm the engine.

At certain part-throttle/cruise conditions and low load conditions, your engine is normally supposed to run at an air/fuel ratio that may be 15:1 or higher...all while being having the total timing approaching 40* or more. Basically, it's on the edge of spark knock. So, you put one of these things on...and guess what? Our ECU's have adaptive control...in other words, it will modify the fuel and timing curves to maintain the proper A/F ratio. Basically, cancelling out the effect of your little "mod". That's why adjustable fuel pressure regulators don't work over the long term...adaptive control...it just leans it out after a few hundred miles, or so.

At WOT, your car normally runs rich...like 12:1 in some cases. Those injectors are wide open. Nothing to be gained by such devices. Better off setting your initial timing up a few degrees and call it a day.

wut about that throttle postion chip that jegs sells for like 90 bucks is that any good does anyone have it

Looking for cheap horsepower, huh?

The only thing I can honestly recommend in the way of ECU performance upgrade is a dyno tune and ECU recalibration. Or, if you have the proper data logging and AFR monitoring equipment....a TwEECer, PMS, or the like. I don't know of any serious performance enthusiast or racer that is using these little gizmos...which says a lot...they probably don't work in the long run...ECU adaptive control. Save your money and do it the right way.
