What makes our Digital Carb Sync Tool the Best?
Long Answer: See Below...
Old-School analog mechanical and liquid column (manometer) vacuum gauges are very rough measurement tools. It is similar to using a 100-lb torque wrench to tighten a tiny screw. You can use it and it'll get you in the ballpark, but you will never get it dead-on accurate.
This image shows vacuum cycles from a running engine with the intake stroke circled for reference.
This pulsing signal is what drives mechanical and fluid vacuum gauges crazy!
Each intake stroke causes a rise in engine vacuum. After each intake stroke, the vacuum slowly drops during compression, power, and exhaust (3 strokes).
Mechanical and fluid gauges incorrectly average this entire signal which provides a misleading false-average.
ONLY the intake stroke should be considered when synchronizing carburetors or throttle bodies!
Our digital carb sync tool uses sophisticated algorithms to analyze & measure only the intake stroke. This makes our device true "Digital Peaking Manometer".
As a bonus, the software can also count the pulses to calculate a precise RPM making The Digi Sync a highly accurate Digital Tachometer.
Please Note: This feature is designed for engines with only one carburetor (or throttle body) per cylinder. If more than one piston is connected to the same carb, the RPM displayed must be interpreted differently.
A common myth is that carburetor synchronization only affects the engine at idle with Constant Velocity (CV) carbs because they sync themselves. This is very misleading!
The truth is that CV carbs sync themselves only at Wide-Open-Throttle. I know you like to claim that's how you ride all the time, but is it really..?
Synchronization on CV carbs has a significant impact while cruising between 0 and 70 mph.
We've used our highly accurate digital carb sync tool to prove it! The results are shown on these two graphs.
The high-end industrial grade digital sensors used in The Digi Sync are highly accurate within 0.1 inHg (3.8 mBar) which significantly exceeds the specs listed in your repair manual!!
Simply put, The Digi Sync™ redefines engine Carb Sync Tools and vacuum gauges AND IS THE NEW STANDARD FOR CARB Sychronizers and throttle body balancers!
