Since no one has been able to give you a specific answer in nearly a week I'll offer the following.

When I was a grad student at the U. of Wisconsin Engine Research center back in the late sixties I had a 283 Chevy V-8 on a dyno that I was using for emission related research.

The setup had a magnetic pickup that detected a TDC signal as the timing notch on the crankshaft torsional damper passed by the pickup. It was a short, sharp voltage spike that was displayed on an oscilloscope along with differential pressure data across the air and fuel flow paths from low response time pressure differential transducers.

So, if you have a scope with an inductive pickup that you can connect across the TDC signal wire to the EZL you might be able to characterize the wave form of the M103 TDC signal.
