Thread: Holley stand-alone Digital Dash Questions

    Default Holley stand-alone Digital Dash Questions

    I’m at the point in my project where I’m ready to order gauges and came across the Holley 553-109 stand-alone Digital Dash, and figured it would be easier and about the same price as ordering all Auto Meter gauges along with a datalogger. I’ve been doing some research on the forums and found a few people having tach signal problems, even with the tach output conditioner. My question is, has Holley fixed those problems since then? The most recent thread I found on the stand-alone dash was from 2017. I would like to know before I spend $1100+. The car is carbureted with a MSD 6530 box. Any info is appreciated, thanks.

    I don't think that application had tachometer problems. I've never had tach input problems with my Digital Dash.
