my friend told me you cant hook up 2 msds on a gsl-se. Why is that. he said only 1.

 

You could, but it'd be pointless. The reason why is the trailing ignition circuit won't improve engine power with an MSD hooked to it. Only the leading is necessary.

 

i thought it was one to leading and two for trailing.

 

but isnt the spark the same for both leading and trailing, and if why 2 msds for just trailing

 

You can run 1 MSD in direct fire mode which does fire both leading plugs at the same time in wasted spark mode. You'd then have to hook up a 2nd MSD and run it through the distributer to fire the 2 trailing plugs.

The standard way to do it is to use 1 MSD and run through the distributer to fire all the plugs. However this is not getting nearly as much power as the wasted spark mode since the spark has to jump a larger gap in the dist. cap and then the 2nd gap at the plug. In wasted spark mode, it fires over a longer duration and with more intensity. You don't need a 2nd MSD to fire the trailing plugs though. You really won't get any more usable power out of it or at least not enogh to feel.

 

my friend told me it has something to do with the fuel pump if im correct on that. and can u have 2 msds for just leading would that help me for my gsl-se

 

I don't see anyway that the fuel pump could be a variable.

There really isn't an advantage to using 2 on the leading plugs. You just don't need it. I suppose you can but you aren't going to feel anything different. Just hook it up as a direct fire system with one MSD. You'll be totally happy with it.

 

Use a DIS coil.
