    I did some research before I bought this distributor but really couldnt find any information so I decided to review to help anyone needing a new dist. This distributor is well thought out and fairly easy to figure out after a little playing around with the timing maps. I bought the big cap hei version because they showed on their video that itll have spark well over whatever rpm I would rev my 455 to. It a built in rev limiter as well, you basically install it like any other dist and hook up the power and tach wires. Make sure you supply 12v switched power and not the standard resistor wire.

    Then you leave key on and use bluetooth from your phone app to access your dist. Then go to generate a timing table and itll ask you what maximum timing you want at any given rpm, after you input this it will generate a timing table to run your engine. I had a problem at first where I clicked keep timing at 12 and it started glowing the headers at 2k rpms. Once I figured it out and unclicked that box the car ran good and the timing seemed spot on. One thing about this dist is it works off of full manifold vacuum so if its in a high vacuum situation like an idle it has lower timing, but if you have a big cam or put it in drive it senses lower vacuum and adds timing to help the engine idle or help it overcome a larger cam. This is also editable in the timing map to add or subtract timing in any given idle or full power situation. Anyone on the fence about whether to get this dist I would encourage you to try it, I havent driven the car yet but so far with breaking the cam in and dialing the carb in for idle and response I havent found a better substitute yet. I am including a timing map I made, the bottom white scale is rpms and the left white scale is vacuum with the upper part of the scale being hightest vacuum.

    Pretty cool, is this a new to the aftermarket distributor?
    Any pics of it?

    After going to their site and watching the videos, I'm impressed. Would this be the proper thread to ask if any others have tried this distributor? How about any engine builders? Might be a good dyno tuning tool?

    Looks like a great product, it is nice to see the price for Buick is close to the same as Chevy.

    I can't wait to see the drive ability of it but from just running in im thinking it will be a joy to drive with the adjustable timing

    "Bluetooth from your phone app to access the distributor" I had to read that twice....amazing

    It would also provide the ability to retard timing at higher rpm like the old Stinger S4. And no separate boxes to hide/mount. I’m all ears.

    I like the theft prevention feature, but I'm a bit intimidated about setting the timing tables without any sensors to monitor.

    It would be interesting to see how it holds up to the heat cycles, from cold to hot to cold, which could be several times a week, maybe even a day with street driven cars. I like the concept, just don't lose your phone while in the theft prevention mode!

    Very true!
    Im all for new tech/ideas, but I think it goes too far when you can use your phone nowadays for near everything, I'd hate to rely on my phone for my car to start, hell, I butt dial people enough as it is:mad:

    I'll wait until they come out with a point replacement ignition module. I don't need or want to replace my entire distributor.

    I do like the capabilities of this system. Being able to set your ignition curve from your phone via Bluetooth is fascinating, long overdue IMO. I especially like the "kill switch" function.

    I've been eyeballing these for a while. Glad to see you've liked it so far, let us know how it holds up! I like that they are making them for a wide array of different, and sometimes odd engines. They have them for our 231, 215-350, nailheads, and 400-455's. That's points in my book. I will likely try one on the new motor when it's done and in the car. Dad is doing a carbureted ls in his c10 because he understands carburetors basically. I was blown away at what all the msd box for that setup could do, and then these guys came out doing nearly everyrhing the msd can.

    I wonder if there would be an advantage to this over the "Dual Sync" distributor Holley makes that couples with the Sniper EFI (for people with the Sniper). I am fully planning on getting the Sniper with the Dual Sync and the Holley ignition module all together, but this may be an interesting alternative.

    The Dual Sync also offers timing control, and what I'm interested in specifically is the timing retard per boost feature.

    Not understanding those vacuum numbers on your table.....

    Is see that too vac numbers on left are not normal numbers, sounds like a cool system.

    I didnt understand them at first and still dont completely do but I will say that the higher numbers on the left correspond to higher vacuum numbers
    with the engine running. I think they have to use this particular formula because its how the new engines read boost and vacuum. The only problem I
    have with the system is they really dont explain how and why they do this and you have to figure some of it out for yourself. Other than that the system
    is great and very, very tunable. I really liked the ability to add timing under a load idle like when you put it in gear so itll help overcome a large cam by adding
    timing to the scale and also being able to do it with the engine running and seeing the immediate results.

    They seem to correspond to highest vacuum the higher on the scale you go, it also depends on load on where it is on the scale. I added timing when you put it in gear from 12 to 16 and it allowed it to idle smoother so it didnt die. It has a 310 hydraulic from ta and their info shows a fair idle which is a bit choppy

    The vacuum numbers might be in kPa (kilopascals)

    That makes sense I thought there would be a conversion chart for the vac reading.

    I have what is called Garman Mechanic that hooks up to my GPS in the car. I have it in a Toyota Corolla XRS, it has a high revving motor (8 grand). I noticed at cruise the timing will read at 30* advance but the moment I stomp on the gas the timing drops to 22* and stays close to there most of the way thru the rpm range. The engine has variable cam timing and hard to see what that timing is at 7500 rpm need to shift after that but I will try to look and see what it really says at the top of a gear.

    I would like to know where this distributor can be checked out at and the name of it.
    Thanks, Guy
