bmw e36 tacho

 

this is a 1995 car

1-infinity 6. using lso5 setup as tacho. I see the output from the inf matching duty on my meter. Im setting the ls5 calibration array values by hand to test a response. the tacho does not respond. is the tacho input to the cluster supposed to be a ls signal based on duty? I give it values from 10 to 100 with no change.

2-the wheel speed sensors are the magnetic style sensors right? do they get assigned to the driven on non driven wheel inputs or are they hz or vr?

The tach works by receiving a

The tach works by receiving a fixed duty, variable frequency signal.  You would just set the duty to 50% everywhere and then use the LS5 Frequency table to output the correct frequency for each rpm.

Unfortunately we don't know what the wheel speed sensors are but the front would obviously be the non-driven input and the rear would be the driven.  If hall effect they'd go to Digital 3, 4 or 6 (C1-28/29/31); if VR they'd go to VR 2 or 3 (C1-54-57).  Then setup the sensor assignment in the wizard in Input Function Assignments.

worked like a charm for the tacho. wheel speed is VR just need to test it. its wired. even created a virtual channel for the flex fuel sensor temperature that seems to have good values.
