I popped open my 165 ECM the other day ('89 TPI 350) to check this out,
and though it has a left bank / right bank wiring, the traces are
soldered together on the ECM board. So, in the case of the Chevy TPI
8-cylinder motor, they all fire together. :) (IIRC, only has one
injector driver inside the ECM too.)
