Not sure how easy that would be without some other method of differentiating the noises. I would be interested in one too. Perhaps, AndyF or Rich from Fast EFI will chime in? 1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

Will actually pull timing out of individual cylinders if it hears a knock. Last edited by MarkZ; 11/29/20 05:48 PM. 1987 Fifth Avenue - 512/518/D60
