Yes on both, for most Speeduino boards. The Denso 129700-4571 coils are passive ("dumb") without built-in coil driver, so you can add any of many drivers such as the Bosch 0 127 100 200 "200" or "BIM200" dual-channel driver modules for two coils. Speeduino IGN1 and IGN2 outputs go directly to the BIM200 signal inputs as below.

This thread almost answers a very similar question that I have about igniter and dumb motorcycle ignition coils. I have two single output ignition coils on a bike I'm converting to Speeduino. Each coil has a primary resistance of ~4 ohms. Try as I might I cannot find any information relating to suitable primary resistance ignition coils and coil igniters compatibility.

So my question is, do the typical Bosch two channel igniters suggested here have a range of acceptable coil primary resistance? And does around 4 ohms sound like it's compatible with the Bosch igniters? I just don't want to hook stuff up and though ignorance blow something up before I even get started. Thanks for the help.

Coil driver (igniter/ignitor) info is limited for factory modules, as they only expect it to be used in their systems and with their specific components. What I usually assume, is the voltage and current for the dwell period it was originally employed to handle is a reasonable limit.

A 4-ohm coil is relatively high resistance for coils, with lower amperage involved, and would indicate a lower driver load than the factory originally intended. The perspective is that the (watts * dwell = load) should be as-reliable if it does not exceed the same load as the original application. Again, these are assumptions, and not far from a wild guess. ;)

For aftermarket components (e.g., ISL9V3040)the issue is much clearer, with component specifications readily available.

Thank you PSIG, that's clearly why I can't find the information regarding the Bosch coil driver. I will look at the aftermarket item that you mentioned. That will make things clearer for me.
