I hate to, but I have been toiling in front of this computer searching for the last hour and I have gotten no where. I have installed my a/f controller and wish to use the pressure sensor wire instead of tps. So, as one may have guessed; I have an s4 non-turbo and I would like any help- preferably a diagram or sketch cause I'm an idiot- on locating the pressure sensor wire at the ecu. Thanx a buch

 

Don't use the stock boost sensor.

Get a GM style MAP sensor and use it instead. Pressure vs. voltage curves for these sensors is all over the 'Net.
