I'm trying to get my Dakota Digital VHX gauges to display the speedometer output from my 2013 Camaro SS ECM/TCM. I have a Speartech standalone harness in which John has pulled an output from C1 X1J1 pin #57 to connect to the VHX "sender" port. I have verified that the wire is pinned correctly and that it has good continuity. When I try to calibrate the speedo, it says that I am not getting any "pulses" out of the ECM. Is there something within the tune that needs to be adjusted in order for this to work? Thanks in advance.
