miss fire after fitting megasquirt.
 

finally got my car running on the mspnp2 however the car has a really bad miss fire. I pulled the plugs. 1 and 4 were covered in black carbon. 2 and 3 were wet with fuel. any ideas?

Please post a copy of your tune file and a data log of trying to get it to run - this will give everyone more to go on.
