Our customers LOVE The Digi Sync™! Here are just a few of our many testimonials:

I always thought I would leave the job of a carb sync up to my mechanic but The Digi Sync made it very easy for me.

I’ve tried several other sync tools and they always left me with an "I guess it's close-ish" level of confidence. The Digi Sync Digital Carb Sync Tool had my carbs sync’d in no time flat and I’m very happy and confident in the results!


WOW! Amazingly easy to use and spot on accurate!!!! Far better than any other mercury tube or manometer based sync tool.

Jana Schutt

The Digi Sync is easy to use and very accurate. I will never go back to the old carb sync methods.

Kurt Anderson

A bike synced with The Digi Sync runs much better and gets better gas mileage than one not using the Digi.
Cracker Jack

The best out there! None better IMO. I was using a Twin Max electronic balancer which was documented to be comparable to BMW shop $6+k unit by Motorcycle Consumer News. The Digi-Sync is much, much better, the latest technology. I love using it so much, I used it on my DR200 Thumper just to watch the numbers move.


Accurate and you’ll have those carbs sync’d in minutes! The Digi Sync uses short-term averages and shows you a number rather than forcing you to interpret a bouncing analog device.
If you find yourself working long enough at synchronizing the carbs to burn all the fuel in the carb bowls you're definitely NOT using The Digi Sync.


Amazingly accurate, simple to use, and easy to store. After years of using mercury tube and then viscous liquid synchronizers, I discovered this. With my 4 channel I can do any engine from 2 to 4 carburetor/throttlebody’s. No need to plug the unused ports as it self adjusts. No need to throttle down vacuum tubes to keep the gauges from bouncing. It also accurately reports RPM. On top of all that the customer service is fantastic!

The Digi Sync is an easy setup with the screw on hoses and internal battery! On start up it Calibrates which takes maybe 5-8 seconds then you are good to go! It is easy to read and Great that it has your Idle RPM too! No playing with fluids or needing a 12 volt source with this setup! Thanks for offering such a great tuning tool and setup! Great safe riding! p.s. I only need 4 channels, but bought the 6 channel unit and love having the option to do a friends six cylinder too!

One reason I went with the Digi-Sync is the fact that it shows RPM's which is great if you only have a speedometer. 
The most missed step after a carb rebuild is the Idle Drop Procedure. This is where you set your air/fuel mixture screw to optimum settings.
You adjust the mixture screw to reach the highest RPM's (where the engine operates the best).

I usually use an old mercury manometer to set the throttle bodies and/or carbs. I hooked this new fangled gadget up and was expecting to see my throttle bodies well out of sync. They were within 3 values of what this device shows. I thought "Great I just spent a bunch of money when my old gauge was setting them just fine". I went ahead and adjusted until they were only 1 number max apart and put everything back together thinking I bought something I really didn't need. I took the bike out (FJR 2008 140,000 miles) and immediately noticed that the bike was running smoother. On the highway acceleration was about 5-10% better. Never been this quick. This is a good investment to keep this old bike running like new, and a new bike running better than factory specs!

It unlocks ALL the horsepower available as it wuz MEANT to be.  Having been around tools and gauges most of my life The Digi Sync Looks like it should cost way more than it does.
