Verified using engine simulator connected to FOME ATLAS ecu that when the FOME ECU is setup for a 10 cylinder engine in a wasted spark configuration, so using 5 ignition outputs, that the firmware is not responding to the cylinder offset settings.

When firmware is setup for individual coil packs (so 10 ignition outputs) it does respond to the cylinder offset settings correctly when tested and verified. However it appears when the ignition coil output is shared with cylinders with different offsets, like 0 degrees and -18 degrees in this example, the firmware does not respond to the change in the cylinder offsets inputs in tuner studio when setup for wasted spark.

Research direction

No source files or tests are named. Reproduce the report with the engine simulator and FOME ATLAS ECU using a 10-cylinder wasted-spark setup, then compare ignition scheduling with the individual-coil configuration. Done means cylinder offset changes are honored when ignition outputs are shared by cylinders with different offsets.
