Running a 16197427 PCM with TunerPro RT. Set the base timing by disconnecting wire from Distributor to PCM. Set with timing light on balancer to zero degrees. Reconnected wire from distributor. Timing as seen on the TunerPro screen is something totally different from that read off the balancer with timing light. Should I disconnect the knock sensor and insert a 1Kohm resistor in place of the knock sensor then adjust the timing tables in TunerPro?
