When To Sync Your Throttle Bodies / Carbs
Preparation for a Track Day or Performance Ride
Ensuring your engine is running perfectly before a high-performance event or ride.
Misfiring or Backfiring
Inconsistent firing or backfiring during acceleration or deceleration can be caused by out-of-sync throttle bodies or carbs.
Recent Maintenance or Modifications
After installing new parts, adjusting valves, or performing significant engine work, syncing is often needed to ensure everything runs smoothly.
Engine Tuning
For those looking to get the most performance out of their engine, syncing the carbs or throttle bodies is a crucial step.
Rough Idling
If the engine is idling unevenly or stalling, it could indicate that the throttle bodies or carburetors are out of sync.
Poor Throttle Response
If the throttle feels sluggish or the engine hesitates during acceleration, syncing might be necessary.
Vibration Issues
Increased vibration, especially at certain RPMs, can be a sign that the engine’s carbs or throttle bodies are out of sync.
Fuel Inefficiency
If you notice a drop in fuel efficiency or the engine is running rich or lean, syncing can help restore optimal fuel-air mixture.

Product Description
- 6-Channel Version: Ideal for complex, multi-cylinder engines that have up to six throttle bodies or carburetors. This version is perfect for professionals or enthusiasts working on high-performance engines, where precise synchronization across multiple channels is critical for optimal performance.
- 4-Channel Version: Suitable for engines with up to four throttle bodies or carburetors. This version strikes a balance between capability and cost, making it a great choice for those working on standard four-cylinder motorcycles or performance engines that require reliable synchronization.
- 2-Channel Version: Designed for simpler engines with one or two throttle bodies or carburetors. This version is perfect for DIY enthusiasts and those working on smaller or less complex engines, providing an affordable yet accurate solution for maintaining engine performance.
*The 6-channel and 4-channel versions can also be used on engines with fewer channels—just leave the extra hoses unattached when calibrating for precise results.
Can I Use The Digi Sync To Replace My Traditional Vacuum Gauge?
Absolutely! This would give you two tools in one.
A traditional vacuum gauge can be helpful in any repair shop for diagnosing a large variety of automotive issues.
To do this, connect one of the hoses and ignore the others to get a highly accurate vacuum reading.
Will The Digi Sync Work On My Vehicle?
Generally, the answer is YES if you have a performance vehicle.
Our product works on any carburetor or throttle body that has a vacuum port where you can connect our hoses. Some older styles, such as Bing CV and Holley carburetors (found on many muscle cars), do not have this port and must be measured from the mouth of the carburetor, requiring a different style tool.
The Digi Sync would not be used for synchronization on any vehicle with a single carburetor or throttle body. Generally speaking, these are non-performance vehicles. This includes most Harley Davidson’s and basic automobiles.
What numbers should I use for synchronization?
Many people try to overcomplicate this. Even your shop manual likely explains dialing your numbers into a specific range. In reality, the actual value isn’t important. What is important is getting all the numbers to match (be “synchronized” with one another) at the desired RPM (typically idle).
It’s really that simple! Doing this will ensure your engine runs optimally.
Will I be able to get all the numbers to match perfectly?
Some engines, particularly older engines, simply won’t allow for a precise synchronization. The Digi Sync simply lets you get these numbers to match as closely as your machine will allow.
In general, values within 1-2 kPa of each other are considered VERY good. However, even values differing by as much as 8 kPa can still lead to acceptable results.
Will the numbers bounce around, like on my analog gauges?
Typically, the values shown on The Digi Sync are stable within a couple of digits, but they can bounce around for the following reasons:
- You have an air leak with your tool installation. Push the hoses tightly into the unit. Make sure they don’t pop off the unit with a light tug. Also, make sure the hoses are securely connected to your machine. Use clamps, or temporary zip ties, if necessary.
- You have an air leak on your machine. Check for air leaks on the entire intake system.
- This highly accurate instrument is indicating there is another issue with your vehicle. An example of this would be burnt fuel valves.
The units displayed are kPa. Can I change this?
Yes, press and hold the power button to cycle through the following units:
- kPa (default at every power-up)
- mBar
- InHg (x10)
- mmHg
- PSI (x10)
- DigiSync Ver<3.1 (these values correlate with older Digi Sync units)

Haven't been able to use it yet.
US6 channel
I ordered and received my 6-channel Digisync quickly. I am impressed with the storage case to keep it from getting damaged and the ease of use. I followed the instructions to check my V4 and it was a breeze. This unit is a major step up from the old liquid style sync tools I have used in the past. It’s a bit more costly but well worth the extra money due to the accuracy and simplicity. Thanks Digisync!
United StatesExcellent product!
I use the Digi Sync on the bikes I restored and maintain. So very easy to use and accurate. One of my favorite pieces of equipment when it comes to tuning my bike!
USSimple & smart
Very user friendly and comes with accessories and a case for protection.
USWorks great and good CS
Got one to keep my carburators balanced. Super easy to use and works great. Mine arrived missing a screw for the back cover and they sent one out right away. Had no impact on the function so I was able to use it in the interim. Great experience and a great product.
