With an electronic throttle body, the percentage you push the pedal is not a 1:1 relationship (or at least, more than likely is not) with the percentage the TB opens.My question about the unit is what can it Really do? The throttle pedal is connected to a potentiometer which can only be read by the ECU as a analog value. So what values does the thing send to improve throttle response? A full throttle signal at half depression? Half throttle when the pedal is just touched? Someone should hook one up to a meter and see.
This basically hijacks the TPS voltage and manipulates it to a different value on the applied pedal position table. Basically if the car associated 10% throttle pedal applied with .5 volts, with this installed the computer would instead see .7 volts and the computer would tink you're actually pushing the pedal down 15%, 20%... Its a piggyback.
