    Yes, make sure the coil wires are connected correctly, and then make sure the spark wires are correct on the pack. I have my coil turned so the harness connector as at the top making it CBA instead of ABC as every single picture you see has it (with the harness connector at the bottom!). This is what screwed me and it did run, but it sounded like it had one hell of cams in it and it was a stroker. It smoked and ran like crap but once fixed it fired to life and ran smooth.

    I'm not sure about the VE table, I don't see how it would need much or if any adjustment after changing cycle but I could be wrong. I'd suggest changing it to simultaneous and seeing what it does and then worry about the table and everything else. You will want to get it to idle first and then mess around with everything else. I'll check the rest of your tune in a bit, warm up enrichment might also be another area to visit.

    If you have a wasted spark compatible timing light you'll be fine. I don't even know what kind of light I have since it's like 15 years old but it still works with wasted spark. All you do is put the clamp around #1 wire and pull the trigger. If you have the setup manual for ms3, refer to page 53. You disable the fuel, set your timing to 0 degrees (Ignition Settings -> Ignition Options / Wheel Decoder -> Cranking Advance), put your timing light on and with someone cranking see how far off, if at all, your timing it and then adjust it.

    EDIT: Your youtube post doesn't seem to be working.
