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
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
