Coil questions

[richardpr]

Received this question and turned to you guys for help

Hi,I was unable to find reliable information on your coil, so its hard for me to say. If you wanted to use the factory coil, you will need to find out if your coil requires a 5v logic level input, or a high current ignition input. Do you know if your coils fire wasted spark, and if your engine is even fire?*

This is too confusing

I'm just a shade tree mechanic, as are most of us, if I suspect a bad coil I'll either try a new one or a known good used one, troubleshooting 101.

As above... it's confusing.

BUT......


From your wording... whoever was talking/asking... only knows about automotive type ignitions. You have a normal, high voltage CDI system. SO... the coil takes HV. Assuming its your ski listed... then the CDI is what charges, and fires the coil.

I was checking for a programable ecu and was asked that. Just looking around

What kind of machine are you talking about ? Is it the rfi ?

The carbed two srtrokes are wasted spark. (both fire at the same time) not sure abouy the rfi though.

As for the rest you could use a 5v logic if the cdi likes that. It wouldn't require high current that way. All your doint is hooking up the ecu between the pickup and cdi but there is no guarantee that you would be able to control ignition timing with it that way.
Although best thing to do is go with high current and not use the cdi and coil.
If your going directly to the coil then you need another type of coil that one can be fired with 12v.

In that case.... it's TOTALLY irrelevant. You will strip off all the Seadoo controls, and replace all of it with whatever the new ECU wants.

The part about an odd fire ignition is an old "Ford" thing.


If you are looking at a MegaSquirt, or something like that... you will need to install a pickup wheel, and coil.... install a regular 12v ignition coil... and do all your own tuning.

I know about most aftermarket units... but helping tune an engine from this far away will be too hard. AND, just be aware, that the process of tuning can leave you with a roasted engine. (if you don't know how)

I am aware. I worked at a dyno and saw some gnarly stuff
