can I hook up a dis-4 (4 input trigger points) two lt10s with the x4 box. Thanks

 

Can't be done. The DIS-4 is not a true 4 channel amp. It only uses two capacitors. There needs to be about a 20* minimum spread between each channel for the capacitor to recharge between ignition events.

If you want to go MSD two DIS-2 boxes would do what you're asking. But at that point you've sank enough money into it that you would be close to a true 4 channel box from M&W or Autronic.

 

Just to ammend that...it's not just the capacitors. The processor of the DIS-4 also needs 20* crank travel for switching. It's just not fast enough to control the unique needs of a rotary.
