Superjet CDI Differences

[John_Ciocca]

I have a burning question that nobody (I have spoken with) has a quality answer to...maybe you guys can help:

I called Advent to see about getting an Advent CDI and they told me that this product is only for 1996 and up Superjets because their Advent ignition needs the 62T flywheel and stator. They said the product will not work on 61x motors (1994 and 1995 Superjets) due to the different stator and flywheel.

Okay I can buy that story.....when I look at the Pro-Tec website I see they offer two different modified stock CDIs. One for the 62T and one for the 61x...it makes it seem as if there really is a difference between the 61X and 62T ignition, flywheel and stator combination when working with the CDI.

If this is true then why does MSD only offer one CDI for All years 650, 701 (61x and 62T). How come MSD does not offer different CDIs for the 94-95 and 96+ Superjets?...Their one product works in everthing no matter what flywheel and stator is installed...but the Advent is dependant on the stator and flywheel? Help me understand this difference.

The only difference between the 61x CDI and the 62T CDI in stock form and CDIs modified by Pro-Tec is with the connector style on one wire. On the 61x (and 6m6 CDIs for that matter) there is one connector that is male and on the 62T CDI it is female (or vice versa, can't remember which one is which right now).

You should be able to run an advent ignition on a 61X motor, as long as on that motor you are using a 62T flywheel and matching stator.

Don't quote me on all this, but I am pretty sure that is the way it works.

Here we go again....nobody ever seems to to get the jist of my question......let me be direct and to the point....here is my question:

1) Why does the Advent need the 62T stator and flywheel to work when the MSD does not? Why??

I don't know why the advent is dependent on the 62T setup... I was just clearing up the contradictory information you were getting between MSD and Pro-Tec.

I guess I'm sorry I even attempted to help b/c I did answer one of your questions, as in bold above in my previous post.

I have heard that the 62t style flywheel & stator create a better pulse waveform at high RPM thus giving better engine performance. Maybe the Advent circuitry is more sensitive to noise and requires the cleaner pulses. Someone would have to mock up both setups side by side in a test jig and do an analysis of the waveforms from the stators throughout the RPM range and log the differences. I am not sure of the stator coils value differences between the 61x and 62t, but if the impedance differences are critical to the Advents operation this could also be an explanation. I would think that only Advent could answer this question.

I know that the 62t flywheels are heavier than their 61x counterparts. For this reason I run the 61x setup with a MSD enhancer and lightened stock flywheel.

ease up buddy. he was just trying to help you.:irked:

If I were you I would PM Chuckie from Team Scream (Supertune). He knows a lot about the Advent Ignitions and I'm sure can tell you exactly why you need 62t electrics with the advent.

Hey guys...sorry if that last post of mine seemed like I was angry...I assure you it just came across wrong. Sorry for that Oxnard111. I will contact Team Scream on this but just for the record I asked the people at Advent and believe it or not they could not answer the question.

Keefer is correct, on why you need the 62T stator and flywheel with the Advent CDI, a better signal on the pulser (trigger) coil. One of the main reason the differences with the msd enhancer it uses source coil on the stator to generate the power for the CDI just like stock Yamaha cdi. :frown:
The stock Superjet system is a true magneto ignition and charging, the only reason you need a battery is for the electric starter, if yamaha wanted to... it could be fitted with a pull start The Advent runs in total loss and does not use the source coil for its power to generate spark, instead the Advent uses 12v battery power.
Because you are not disposing or disconnecting the stock charging system and remains functional so you still have a charging system.
Advents will make Horsepower, but must be used in the correct manor.
Msd enhancer timing curves (not much of one) are no match for what's available with the programmable Advent CDI. As far as flywheel weight differences, 62T is a little heavier, But I can overcome that with my engine set-up/tuned package and be way ahead of an MSD enhancer package.
If your really serious you need to use MSD dual channel TL...fresh or salt water riding, you have use more care in set-up but there's nothing better on the market now and really never has been for a Superjet ignition.:brap:
P.S. Well back in the day, Vilders did help a lot, but were way too much $$ ($750) not available anymore...

the advent , basically, can use a pulse signal , and fire the coil more accurately than the 6m6/61x pulser coil can.

the 62t stuff is a stronger more accurate pulse, the advent , I assume is designed around this accurate of a timing situation.

its all about how much you want to tinker, how much you want to ride, and WHO or what you can afford to have done for you.

to me, light flywheel, msd enhancer, and stator timing advance is pretty cool.

 

[keefer]

Thats all this po boy Tennessee redneck can run right now. I would love a fully programmable high energy light flywheel ignition but don't want to spend $1300 or so to make it happen. I kind of like the reliability of the stock stator with static advance and an enhancer for now. Pretty good brap for low $$$. BTW my stator/flywheel is 13 years old and the enhancer is 10+ years old and still making spark every time I fire it up.

I also thought the Advent can only use the stock flywheel, and doesn't work with the aluminum Rad flywheel for some reason.
