inition amplifier

[a.tapos]

Hello

 

I am after running a bmw 328I as wasted spark using 3 ign drivers and either a 6 post smart coil(or 3 x2 posts)

 

OR

 

Using a ignition amp with 6 stock bmw dumb coils to run wasted spark

 

I am guessing a 3 channel amp would do this(I believe link sell one)

 

What are peoples experience's with this and am

 

Thanks

Hi Andy

 

You need one igniter channel per coil.

So if you kept the stock coils you would need two of the three channel igniters.

If you pair coils on the output it halves the available current and you end up with a very weak spark.

 

The 3 dual post coils are a good option and if you get smart coils saves on an igniter. Note if you go with dual post coils you must run resistive spark plugs.

Thanks for the quick response

 

that's what I was leaning towards.

 

so really either 2 ignition amps or 3 duel post coils are the best way to do it.

 

would a 6 post say ford v6 coil work on stock link drivers or would that need an amp?

 

thanks again for your response

Vectra coil 3 channels and wasted spark

 

should work better then buying ignitors?

 

thanks

That would be a good coil pack but I suspect it will still require an external 3 channel igniter as it only has a 4 pin plug.

This would be a 12V in and the 3 signals from the igniter.
