E38 ECU J1/X1 Pin 48 Tach Signal readable for Racepak IQ3S Dash?
Dear all,
I already read all threads about the way to setup the ECU for the output of the tach signal by using Pin 48 from connector J1/X1, like this: https://forum.hptuners.com/showthrea...ch-(autometer)
I have a Racepak IQ3S Dash and I'm looking for an answer if I also need the pullup resistor or if I don't, because it's a digital dash and not a analog tach.
I also have a MSD RMP window switch, here I will be able to use the digital tach ouput signal to activate the window switch for my air shifter.
I'm not able to test, because I'm doing a complete rewiring with a racing loom.
Thank you in advance, best regards and stay healthy and safe
