torynich Posted July 22, 2012 Share Posted July 22, 2012 This is just a why question. I have the crane fireball xr3000 with a seemingly generic chrome coil on my 72 240z. Everything is working just fine on it but i have a msd blaster 2 coil laying around that i thought i would try out. When i hooked it up my tach stopped working properly it would just randomly jump around and the car ran like poopie. Any ideas why? Quote Link to comment Share on other sites More sharing options...
