rusEFI would have to bring along TWO DIFFERENT WIDEBAND FIRMWARE IMAGES, one for f0 and one for f1.
Is there a chance to make a universal f0+f1 firmware image? Just an early chip detection (using an external mcu pin tired to gnd or something?) and two branches of code to configure the hardware.

Re: Hellen 128 Mercedes

The primary ignition coil resistance may vary greatly: from 0.2 to 3 ohms. Usually it's about 2 ohms, i.e. the average current is 7A. The dwell duration in running mode is usually 2-4 ms, and for cranking it may be increased up to 10 ms or more.

Most of the MS2 derivatives use just the same BIPs as the Prometheus does and you can just solder B to C and use the signal, but a buffer of driver IC would be the most elegant method I think.
