VSS1 = VSS2 up to 77kph

[Wolf_Tm]

Hello,
I just noticed that VSS2 (relay on rear wheel ABS sensor wires) shows values equal to VSS1 (gearbox output) only if speed is less than 77kph.
Over 77kph VSS2 values start to decrease more the more the speed.
Is that a smoothing lag factor (50) issue, a frequency limitation or a relay issue?
Customer is 1000 miles away, so I can't personally test on the car...
Thanks

I used a 48t abs ring it used to drop out at about 75-80mph changed to use pt4 as the input as it can handle higher frequencys

Sorry, but isn't the PT4 a logic output? Thx

5v logic input or output.
