Does MSD make Ignition boxes that fit rotary engines, cuz I can't seem to find them anywhere?

 

Most people use jacobs FC1000. I am using FC4000, they sent me the 4000 in the 1000 box, free $200 upgrade

 

Yeah, just run the 6A or 6AL. Only on gain on the leading coil. Don't mess with the trailing stuff. stephen.

 

I somehow highly doubt that.
I think the MSD 6A / 6AL or Crane Cams HI-6 are more popular.

Any of you guys ever hear of the MSD6-BTM or Crane hi-6 w/TRC-2 being used with any success for the turbo boost timing retard on our 7's? Don't know how this would work especially w/ our trailing spark but I've always wondered.

 

Cant use the retard unless you have 3 boxes, even then i wouldnt trust all the boxes to be in sync.

A regular hi-6 works awesome.

 

Are you talking about running it on a stock Turbo II or on some kinda turbo'd NA?
You really shouldn't be using those blasted things on a stock Turbo II.
They are really touchy for a turbo'd NA.
We tried messing with a BTM on a SC'd Honda, and it was a royal pain in the ***.
Adjusting the **** would induce too much retard or too little.
In the end, going full stand-alone EMS is really the proper thing to do in terms of ignition control.

would it be best to run 3 boxes on a TII also is there a link or tread to wire them up

 

Why is that?? A 6a or 6al on the trailing would give even better total combustion.

 

I've seen a few MSD boxes for sale recently in the f/s section, actually.

 

I Agree

 

Explain?

 

Search?
This has been covered many times before in prior threads.

I did, but still not convinced. I've been using MSD products for about 6 years now on different cars, i'm planning on a custom setup on my 13b FC engine and doing some research here. I wanted to run 2 msd 6al units and 2 motorcycle coils. I'll search some more and ask MSD tech again what the best options are.

 

The leadings fire twice in each ignition cycle.
Each rotor face effectively sees 3 sparks - first leading, trailing, wastespark leading.
The leading spark is the primary ignition spark for each ignition cycle.
The trailing spark cleans up the combustion, and it's used primarily for emissions.
The trailing maybe contributes about 10% to the total power output - from SAE paper written by Mazda R&D.
Thus, using the CDI on the leadings will give you the most significant gains.
It's also easier to install a single-channel CDI box on the leadings.

best ignition box is the HKS Twin Power:

but, and this is just my opinion, ignition amplifiers should only be really used after you have identified you have ignition issues. happens in some high-boost applications, or high-rpm applications. if you need it for a stock car you have some other issues to work out...

 

I disagree.
I think the Autronic 500R or the MoTeC CDI 4-channel boxes beats it hands down.


-Ted

 

mmmm.... MoTeC.....

 

i forgot that Motec had that. yes, you are probably right.
i have not heard of the autronic unit.

but, can the Motec be used with a stock ECU? i thought you needed the Motec ECU to use it? i don't really know much about that.
also, i think the HKS might be the only unit to provide both CDI and Transistor Ignition, but i don't know how much that is really worth...

 

That's a good clear explanation thanks alot. If i where to install a box for the Trailing it wouldn't harm things right?? By the looks of what you say it's probably overkill to use an extra box on the trailing.

Thanks again ted

 

i am using 6al but can not find out how to make the trailing work

 

You can't make the trailing work, without additional CDI units

 

^^that might be why I can't make my E-manage run my ignition......****** greddy junk.....

time to dust off the Haltech box in the bedroom........

on topic:

Is the Twin power just a re-strike system? or is it capacative discharge?

 

Try and do a search for "autronic 500R" on this forum, and you should get a lot of good hits and info.


Either the Autronic or the MoTeC unit are "dumb" units.
This means you just need to fire a signal into the 4-channel (max) box, and it'll spit whatever back out.
