Review on ⚙️ Digital Throttle Body Sync Tool - Digi Sync 4-Channel, Digital Carb Sync Tool, Vacuum Gauge (Digital Peaking Manometer) DS3 Model - Excludes Motion Pro Syncpro or Alpha Moto by Rusty Calcara

I bought this as I didn't like the idea of using mercury, it got 5 stars in addition to its small size. Easy to use, just turn it on, POST (Power On Self Test) and calibration takes about 18 seconds for software version 2.2. No storage case or magnet is included, so they are optional. The kit does not include a 4-in-1 manifold to test each of the digital gauges on the same vacuum source to determine if bias voltages need to be applied. Finally, the instruction manual isn't detailed and the label doesn't show the 0.113 to Hg conversion required for the values to ensure the vacuum is where it should be. All in all a great instrument, replacing my old gauges and mercury gauges.
