Trivia Question........anyone know what this Vette Doctors Black Box is? - ZR-1 Net Registry Forums

Found this black box on my car recently and not sure what it is. I'm going to call Vette Doctors this week as I'm sure they know. The builder, Clint Hooper thinks it is to adjust the speedometer when the rear gears were changed. It appears to be spliced into the ECM wiring as well.

Any input is appreciated!
