Finally got the L67 PCM running on my engine swap and hooked up to an Autometer electronic speedometer. I get the correct speed in the VCM scanner but the Autometer is displaying ~1/2 speed. I wired it into the VSS out from the PCM, is there anyway to edit the output parameters so the speedometer runs at full speed or am I going to need to recalibrate it manually to match the output?
