6-Channel - The Digi Sync (Model DS3+) Throttle Body & Digital Carb Sync Tool | Carburetor Synchronizer | Balancer | Vacuum Gauge | Peaking Manometer Tune | NOT carbtune Motion pro syncpro Alpha Moto

Balances 2 to 6 carbs. 👍

I bought it to get my BMW R80/7 carbs sorted out, with the digital display showing vacuum levels and engine revs it takes out a lot of the guesswork when you're adjusting,the mixture and idle screws, so you can see at a glimpse what's going on. If you find yourself struggling with adjustment it's well worth checking the volts on the PP3 battery which may not be a particularly good one, I fitted a Varta PP3 and that sorted it. It's well worth the money and I highly recommend it.

I was looking for a digital balancer with its own power supply to balance carbs on aircraft. This balancer is very easy to use and set up and does a fantastic job and is powered by its own battery. It is good value for money. My only slight criticism is does look a bit like a toy rather than a tool but works perfectly.

Purchased this in April 2021. Shortly afterwards I put all my tools into storage as I replaced my workshop. This has probably been used between 2 and 5 times. Yesterday display went all strange and then went off. Sometimes the backlight came on and sometimes not. Battery appeared to be getting hot. Messaged The Digi Sync and they replied really quickly. Sorry not in warranty but sometimes if you re-solder the pins to the LCD that can solve issues was the gist of the reply. Also offered 50% discount on a new one. Thanked them for their quick response and generosity.I found that under the main PCB is a large magnet and this had fallen off and was shorting across the pins under the PCB. So yes this is easy to use and does appear accurate but I do now have concerns on build quality. Another reviewer said it feels a bit like a toy and that is probably true. As it is working again thanks to some superglue I shall persevere but expected something designed for the workshop to be a bit more robust rather than internal bits falling off.

Very easy to use and will have your carbs or TBs balanced in a few minutes, almost takes the fun out of it... almost...

Easy to use and not a lot to get wrong to be quite honest…. Minimal instructions butNice easy scales and simple to read… happy with purchase..

This item is very good can tune the throttle body's very nice easy to use. Have been using it for a while now the only thing I would say is the magnet in side it if its anywhere near the chip it gose off so just be careful with it.

This is great, easy to read and even has the RPM on it.

The media could not be loaded.  As some other people commented, this carb tuner has totally been a great purchase to bring my bike from a hit or miss carb tune up to 100 percent tuned! Before this I used to rely on overall feel or ear to how my carbs should sound. My older 1984 VT750C Shadow was hesitant to start and idle felt like the front cylinder had issues.After plugging this tuner in I had my bike in sync in a minute! Wow, now that's something to be said how this simply works! It's super easy to use also, just unscrew the vacuum screws on your engine, screw in one of the included brass screws and attach the hose to it and the tuner then turn your adjustment sync screw for your carbs and that's it!I will add this to future users, do not screw the brass screw that's included with a socket or wrench! As I found out by slightly tightening it the brass screw sheared off with a piece stuck in my cylinder. I easily removed the part luckily. My advice is finger tighten the brass screws in and attached the vacuum hose.I reached out to support and within minutes I was given details how to purchase more screws at a very reasonable price and shipping to Canada even!

It is expensive for sure, but holy smokes did it make carb syncing so much easier and faster. I have (which wont be for much longer now!) a Motion Pro manometer that I could never get to work properly because one cylinder would always shoot through the roof for some reason.With this Digisync, I spent more time getting the engine up to temperature to do the sync than it took to do the actual sync. Seriously, it took less than 5 minutes from turning on the device (to do the self-calibration), to me having all the carbs dialed in.I just checked and noticed that the Motion Pro is over $150, and when compared to this device, which I paid about $260, which is more than it is listed for now that I am checking again (annoying), but it is still totally worth the extra! The self-calibration is totally worth it, so is the tank mount and not trying to hang a tool off a handlebar and trying to read the pulses in fluid.The only thing I had trouble with was figuring out how to turn it off. You have to hold down the power button for about 1/2 a second. Shorter and it wont register the shut down request, any longer and it will change some settings (auto off, and units).

I bought a 97 Honda Valkyrie last year and while it's ran great, there's always been a small miss and a scent of gas that's stronger than I felt it should have been.Learned about how a carb could be out of "sync" and that one or more of the cylinders could be running lean.Did some research and everything I'm seeing about the process is, for me, nightmare fuel. Gauges that need calibration and tubes of liquid?Called 2 local Honda dealers to me and asked if they could sync the carbs. One of them only had a setup for 4 cylinders and the other was so wildly doom and gloom about the entire process and made it sound wildly expensive.Found out about the Digisync through a Valkyrie forum. Reviews were high and I did as much research as I could online and youtube on the step by step process for syncing as there were some videos, but they kind of brushed over some details I didn't understand and another videos was incredibly detailed and educational, but was for bench syncing.My Clymer's manual was zero help as well.Ultimately, what I learned was that all the carbs run off of one main/consistent carb. Which is the carb that you can adjust the idle on.So, hook up the machine, use the idle knob to set RPM where they should be, then match the other carbs to that one using the adjustment screws.This machine made that process shockingly simple. Once you figure out which tubes need to be pulled AND which carb is taking in the gas from the tank (and needs to be done last), it really was just a process of unhooking and rehooking lines.I was stunned to find that the tach on my bike was wrong. I'd set it to roughly 900 rpm according to the tach. Well, the Digisync showed me that I was over 1000 rpms.I dialed the rpms down to about 940 and was stunned to see that the 4 other carbs were almost perfectly in sync. I was actually disappointed.Then I disconnected the gas line from the last carb, hooked up the last hose from the digisync and started it again.BAM! My problem carb! I had to work quick as the bike is running only on the gas left in the carbs, but I was able to adjust that carb and get it to match the others.Turned off the bike, unplugged the Digisync hoses and plugged everything back in.The small miss on my bike is now gone and the smell of gas is reduced by a not insignificant amount.I'm wildly pleased with this product and will sing its praises to anyone with carb motors!!!!Thanks for an amazing product (that even included the 9V battery!) at a fraction of the price I'd have to have forked over to a shop that probably had no chance of being as accurate as the Digisync!

Calibrates on every start up. Switching hoses shows same readings and I checked against my best mechanical and it was dang close! I am loving the Digi-Sync!
