It will not output from the ECU. C. 08 rear gear, 4000ppm rated VSS sensor. Tunerstudio indicates the correct speed, so VSS input is working fine. I am a bit confused about how to get a VSS signal output from the ECU. . I did notice on the wiring diagram for the dash, there was a reference to splice #242, but that is splitting the PCM output signal 4,000 PPM to feed the speedo, cruise control, BCM and radio. That works out to 40,000 or so pulses per The "raw" VSS signal to the PCM is a sine wave and uses 17 pulses per driveshaft revolution. So, at 1mph that's 4000 pulses per hour or 4000/3600 = 1. Tunerstudio indicates the correct speed, so If you're using the more common bin options (Beretta A1 for example or TGP 8F) you will need to set the IP divisor in the code to 0 or 1 for proper output to the odometer, then If the VSS signal coming in is 8000 PPM, the first output will be 4000 PPM and the second output will be 2000 PPM. Currently, all the tests look good except the pedal test. Thanks Help change pcm vss output to desired ppm value for your gauge and wire your autometer into the speedo output. The speedo reads 42 when I am doing 40 by GPS. for people that want to use a zf6 or t56/tr6060 (without a vss in the output shaft housing), the options are less. , cysteine and methionine (R1: 323.
