I have installed a full MSD Ignition system on my car and have ran into a problem with break up. I am using an MSD DIS 2, an MSD 6AL for the Leading. I have three trigger wires running from the Haltech E6K (Blue= T1, White with Black line = T2, Green = Leading) then from the ignition boxes i run to 3 MSD coils. (2 MSD coils one for each trailing and one dual tower coil for the leading) My problem is for some reason the egt readings are running higher than before and on idle the car feels lazier and and takes longer to start. it would be awsome if i could speak with someone who had done this sort of setup already or that may shed some light on this problem.

Thanks

This is a very easy and straight forward setup, but, i advise against using different MSD boxes for leading and trailing.

The way this is connected, for better results, is like this:

Leading timing (to dual post coil, Ign.Out) to MSD 6A's white wire, with the Light Green wire.

Trailing 1, from White/Black (DigitalOut1) wire, to Channel1 on MSD DIS2.

Trailing 2, from Blue wire (DigitalOut2), to Channel2 of DIS2.

Set the Spark Output type to rising edge, Constant Duty, 40% period, and spark mode to Direct Fire.

If you do it like this you will be fine. Also, dont forget to zero in your timing. If you want/need to call me feel free to do so.

 

It sounds like you didn't change the spark to RISING.

Always gun your timing when changing ignition components!
I bet you're running everything 20 degree retarded...

they have to be different...what do you advise otherwise? Do they make a dual post blaster?

 

3 X 6AL'S on this particular setup.

BTW. Rob solved his ignition porblems. The trailings were inversed.

 

^gotcha...I was thinking boxes = coil
