... Capacitive discharge with a controller uses the trigger from the distributor as a reference signal, the coil is what is discharged in order to create the spark at the plug and the controller is what dictates when the coil will do that... if I'm understanding correctly as to how the system works

I'm not sure what the failsafe is on them. But in reality , a piece of dirt in a carb needle and seat can burn up a motor. A fuel pump failure can burn up a motor. Moisture in a distributor cap causing crossfiring can burn up a motor. A thousand things can fail and take out a motor.

Its like asking , what happens if my lifter wheel falls off on my roller lifters ? Ehh, I'm gonna stick with flat tappet because no roller wheel to break.

These boxes do sort of the same thing an ecm does on a fuel injected car or boat. If they were to fail internally , or not do what they are supposed to you can have issues.

Maybe that's a question for the guys who designed these boxes as far as what can fail in them and what are the effects of it failing.

Does the daytona sensors box have options for knock sensors ?

The "trigger" is usually inside the distributor but sometimes a crank trigger is used. When the magnet passes the pickup a signal is sent to the ignition to discharge the coil and send that charge to whatever spark plug the distributor dictates.
The "box" is where the signal is processed and any delay is introduced in a locked distributor application.

I think you have it right in your mind.

so after further research on the Daytona system it clearly states in the installation/programming download that the reference timing is the max timing set by the triggering device weather it be crank trigger, distributor, etc etc... but even so, in a boosted application, being able to 3D map a timing table to Vac and RPM would be of a great advantage in tuning for idle stability... again just my $.002

we should just go back to the old days lol and stick a Vac Advance system on the stupid thing and call it a day!!!

I don't believe there is a dedicated input for a knock senator.
There are three I/O's on the box and two are dedicated to data logging. The third is programmable. You could use it to switch a nitrous system or to collect MAP.

Give them a shout. The guy was gracious in answering all my rookie questions.

Ok I got a stupid question, I have preloaded maps in my Marine Crane boxes...
These are Mercury timing tables , no good?

I think the problem you'll find with those maps is no timing at idle doesn't work well with your high falootin cams, big blowers, and 1050 carbs.

I'll take a stab at it.......
It's not that the merc timing table is "bad".
It's that the Daytona table (or any real time data referencing table) is constantly manipulating the timing based on rpm and MAP if you program it to do so.

and there it is!!! Joe you da man!! big azz cams, blowers and big carbs need timing at idle... I'm thinkin an ECU and 8 coils is gonna be the real answer
