vehicle speed sensor
hello, I'm doing experiment with my audi a4 '96 1.9tdi car.
I want to cut line of vehicle speed that is sending info to ECU from VSS(vehicle speed sensor), but save speed line in my speedo, to see, the speed i'm driving.
If I'm not mistaking, signal from VSS in a4 is going firstly to speedo - to show speed and calculate miles, and than to ECU- for fuel correction.
I dont want fuel correction, and want to cut this line, before signal reach ECU, so maybe anybody have some advice, if there're risk of driving without VSS, and have some schemas, and can help me to know, which cabel i need to cut p.s. and if there're influence to klimatronic, if i cut speed signal.
