has anyone tried the next level racing g-box performance module? i just ordered one today for my 96 gl . check em out.... www.nextlevelracing.com
Granted the MAF and the O2 sensors determine the air:fuel mix.Originally posted by silvapain@Jan 5 2004, 06:22 PM
Plus, the O2 sensors have the final say in what the air/fuel mixture is, and will readjust if they sense a rich condition. the resistor won't do anything at all. Iv'e tried it on my own car.

the MAF sends an analog DC voltage to the computer of 0.5 - 5V depending on air flow the O2 sensors send a voltage of 0-1.1V where <.4V is lean and >.6V is rich.
Now if lets say i give the computer 5v dc as the MAF input i think that will give 100% duty cycle for the injectors and ofcourse make it extremely rich (on a prettty much stock setup). I dont know what will happen when the O2 sensor notices thate its rich, if it does have higher priority then the MAF input then it will componsate.
Now what is to stop me from giving the computer a 1V for O2 sensor input and a 5V for the MAF input? This should therefore make the car rich constantly. Yes terrible milalge will result and carbon deposits become a problem. But if one wanted to control the fuel to air mixture of the car manualy then it can be accomplished this way.
Right?
Thought? Comments?
Actually to not take away from this thread i will start a new one discussing this scenerio, please reply to this post in that thread. [/b]
