I bought an older Autometer model 3967 playback tach from a gentlemen that used it on a 4 cylinder car. Trying to reconfigure it for a V8 and cannot get the 4 pulses per revolution to save. I press the record button to save the setting Per Autometer instructions but the tach always returns to the 4 cylinder setting. Anyone out there know of a possible different procedure other than what is published by Autometer?

And as aside, Autometer is not taking tech phone calls, not using their online chat feature, and have not answered my email.

Appreciate any help you guys could provide.
