ah ok, makes sense

if you can still get them the J&S vampire/knock detection/prevention system would be an issue if you cant get the MSD to work. You can wire in a switch to the system and retard 2-4 degrees without changing the tune itself

7) If you are using nitrous oxide, connect the J&S “Aux” wire to the nitrous switch. When you hit the nitrous switch, the unit will retard either 2° (S5 down) or 4° (S5 up). You could also wire pin 2 to a toggle switch, and use it to retard 2° or 4° when you fill up with low octane fuel.

this system listens to the factory knock sensors, I did the MSD 2 step harness install so as not to splice into anything. It's basically running the coil signal through this unit so it can delay the signal. If it detects knock/detonation it will pull timing before that cylinder fires again. I also run the better gauge that will tell you which cylinder(s) detected knock
