[Bosch BIP373 igniter driver]

Thanks Rod, The 373 is a basic chip where a J131 may have other supporting circuitry required for its operation hidden inside. Its this additional circuitry that is of interest. The BIP373 pdf indicates only a resistor though this may depend on the link ECU ignition drive signal. Voltage/ max current etc Hopefully the Link guys can give some pointers

[Bosch BIP373 igniter driver]

HI, Is it possible to use a Bosch BIP737 igniter driver with Links G4 ignition drivers directly? Ie ign output via suitable resistor (1k?) to base, collector to coil, emitter to ground? Thanks Matt
