MS2 and LS2 coils
#43
I have the Sequencer ground from all four coils going back to the megasquirt and I have .001 uf caps on the stock miata brown and brown with yellow that are connected to the signal ground. "caps are going from brw and brw yellow to signal ground"
For some reason the car is only firing on cylinder 2 and 3.
1 and 4 are getting 12 volts power and when I hook up my volt meter it reads 12 volts from both signal ground and my head ground. I also get 12 volts out of the signal on all four.
I believe the wiring is correct but it is only firing on 2 and 3. Not sure what I have done wrong.
Does anyone have a detailed wiring diagram?
Currnetly I have
12v to all all the 12v red wires on ls2 coils
Ground going to head from all black ground wires on ls2 coils
Signal Ground going from all brown ls2 coils back to pin 15 on mspnp2 "signal ground"
Brown wire from miata harness going to the signal wire for ls2 coils on 2 and 3
Brown and yellow from miata harness going to the signal wire on ls2 coils for 1 and 4.
I have tried swapping coils and have no luck, 1 and 4 just wont fire.
it does fire 1 and 4 with my stock coils and harness
Thanks for any help.
