The code can pretty much cope with any angle, but they want you to do it kind of like they do on an EDIS Ford V8. So you'd shoot for the missing tooth approximately 5 teeth (50 deg) in front of the crank sensor when the crank is at TDC. They cover how to measure it directly. I think mine ended up being something dumb like 63 degrees or whatever. Just as long as you now what it is, you just put that number in the computer (IIRC you set the engine on the missing tooth and read the balancer). It coped fine. Then, I put it in fixed timing mode and checked the actual timing with a light...at which case you can make adjustments to get it right on, and then forget about using a timing light ever again unless you disturb the crank pulley.
