67 twin turbo dart

Well just checked as far as software or version goes mines up to date with the 3.1.08. Now when looking at the programming that was set up before I haven't touched, on the trigger wheel, with having the 36-1 and a can sensor(from a Jeep) would that could as a dual toothed with missing one tooth, or would it be better to change it to one wheel with missing tooth? If its searching for a dual missing tooth type set up and ones not there could that cause cylinders to not function properly?? Just spit balling to greater minds.
