Benifits of a dual coil MSD TL System

[Freestyleriverrat]

I see the MSD TL w/ single and dual coils. Do they make the single coil systems for the superjets any more or are they all duals now. Is there something wrong with the single coil systems (pro digital), it seem like it would preform just the same? Does the single coil system have less draw off the battery?

Individual coil systems came about with the triple cylinder engines, and stayed. You can set the timing for each cylinder separately to compensate for crank twist on the big engines, but it's kind of pointless on a freestyle twin cylinder.

This was the progression for MSD:
single coil analog - used plug in chips to set retard rate, start retard rpm, and rev limit
single coil digital - more programmable with dip switches on the brain
dual coil digital - same as single, except 1 pickup per cylinder

The dual coil digital is all that is sold nowadays, so if you want something else you're buying used, very used normally. Performance is pretty much identical, though probably a tad more voltage out of the individual coils.

I'll agree with that! I do think that the dual coil uses a bit less in power and is always a plus to be able to adjust timing to each cylinder especialy with the newer dry pipes out there now!!

When you got a coil failure, it's a bit cheaper to fix. Whatever that's worth.

With a single, you can install 2 pickups on the stator plate and if one fails, just plug the other in. I had more trigger problems than anything with my system.

 

[Matt_E]

Yeah, I agree with you. However, the trigger problem can be easily fixed.
It's the way MSD manufacturers them and makes you install them.
Once the triggers break, they, too, can be relatively easily fixed.
I have three backup triggers laying around, but I am still running my two fixed "Ghetto" triggers. They work like a charm.

I did just recently have a single tower coil break. The tower itself broke off.

Cool, thanks guys! Good info

Is the MSD "better" than the Wax ignition for freestyle? More power, reliability, cost?

 

[Matt_E]

A new MSD Total Loss costs 1200 dollars.
And it needs some work before it's reliable.

I think I got a good deal on the system I picked up. It is a single coil Pro Digital unit that has very light use for $500 and everything works :fingersx: I will do a couple things to it like move the brain away from the coil, but it looks like it is good to go. I also want to get rid of the plastic wire looms as those can hold moisture. A plastic wrap is a little better or even just small zip ties.

 

[Matt_E]

Holy crap...I wouldn't call that a good deal. Perhaps with today's Ebay prices, it is.
I paid 375 for my dual channel TL.
I paid 175 for a complete analog, and 275 for another complete analog

I sold one of them for 230, and another for 300 or so.

 

[Freestyleriverrat]

SOB :banghead: :haha: That is nuts that they go for almost 1200 new and like 300 used. The guy said he has only had it a couple of months, no corossion anywhere in and everything is like new condition.

I bought mine off ebay this past winter just like yours and paid $405.00. I was glad to pay that verses the $1200.00. Point to know. I can only use about 2 and half tanks of gas before the battery needs recharging. Normally not a problem. Last week I took the kid to a lake futher away than normal and to save gas we just stayed the night at the lake. Went to ride the next day and only got about an hour of riding in before we were stranded in the middle of the lake. Had to come home early. Lesson learned is to take a battery charge with you when staying over night.

I think you got an ok deal compared to the price of new. MSD raised there prices some time early summer last year (05). They were around $800 so used ones were getting less. Why pay $500 when a new would only be 300 more. It is different today.

Considering it had only a few hours of use, that's better, but still.
Maybe I'm just a tightwad.

Lakeman....buy an extra battery. I just did that, for the same reason.

My main deal was I was not really in the market for one but just kept my eye out for a total system. I have seen several guys post on here looking for a setup and they did not get 1 response. I figured since it has light use, everything works, and it is a single coil set up it was not a bad deal. Although it is a little more than I would have liked to pay I really have not seen to many whole systems for sale lately and there is no way I was going to pay 1200+ for a new system.

We will see how my batteries hold up, I have 2 lead acid batteries. I typically only ride for about an hour at a time so they should be fine.

[Matt_E]

And speaking of being a tightwad....I just picked up a mint Riva girdled head with all hardware and Orings, and dual 48mm Novi Maxiflows on an R&D manifold for a very decent price.

what a tool :dunno: Wait that was me :biggrin: Still this system has very light use and was probably say $900-1200 new. But considering what everyone else finds them for I think I paid to much. We will see..........but the LED still works

 

[SuperJETT]

I paid $150 for my single coil digital setup that I ran for a year or so. I sold it for close to that, just a little more but that was with the custom plate geek made me and some other nice things I had done to it.
