Kevin you're the first person I've ever talked to who already knows what a split pulse header is.
Nice to talk to people who actually ... know stuff ... now and again.
Ever read some of the PhD dissertations from Linkoping University on Ionization Gap sensing? You can calculate everything from MBT, to EGT, to Torque from the ionization trace. And all Trionic Saabs already use the system to detect knock. The guys at Linkoping actually use a Saab engine as a testbed.
