Finally after changing everything, talking to a lot of people. Well my mechanic which since installed said the new flywheel was the issue he was somewhat correct. The reluctor ring is just a tiny bit larger in diamater than a uuc and factory which are the same size. The cns
flywheel reluctor ring was just a little larger so when you reved up or heat got into unit it just barely hit the bmw sensor. The smart mechanic Viteks auto (cALGARY ALTA) will finish putting car together tomorrow and i will get car back. I hope this helps everyone else that runs into this 1356 misfire. Yeah now i get car back, lets see what it can do at the track in a week or so have to break in new clutch...

No wonder that was so hard to resolve! Congrats and best wishes with your new clutch.
