Other challenges of reverse engineering a '0411 / TBI system include:
Low impedance injectors (TBI) vs. high impedance injectors (native to the '0411).
Injector firing, TBI injectors are firing every Distributor Reference Pulse (DRP) vs. '0411 firing injectors sequentially using the cam position sensor to signal when #1 cylinder is at TDC.
The '0411 Spark Tables (low octane / high octane / optimal) bases timing on grams per second flow (from the MAF sensor) vs. RPM. The TBI spark table timing is Kpa (MAP Sensor) vs. RPM's.

I'm not against the R&D developing an '0411 / TBI system. I'm challenged with the effort vs. net gain?

I wonder about the possibilities using an '411 with the 8 injectors and dual trigger distributor, see pic below.
