Its hard to say, because we only got the engine running through my distributor, not using the CAS/coil combo. By the time we got it running, it was pissing down and we werent in any mood to completely replace the ignition
But the injectors are definitely working perfectly, so thats a plus, and now Ill be using COP's, once hes sent up a new Megasquirt with 4 spark outputs.
He reckons it was probably a dodgy coil, but I had 4 to choose from, and no combination seemed to work right..
