Lt-1 Tach Filter
This topic has been on before, but I have a question as the the "electrical" location of the tack filter on a 95 LT-1. The factory manual shows wires from the coil to the ignition coil module and from the module to the PCM. The PCM provides a tach output (pin 13) that goes to the tach. It looks like the only place the filter could be would be on the tach output from the PCM. So, the tach gets it's input from the PCM and not from the coil, like on the L98 and others. Is this correct?? Thanks. Sid.
