Inductive smart coil wiring

How do I wire the AEM High Output IGBT inductive smart coil if I am upgrading the ignition coil? Do I wire it from the plug &play jumper box or from the Infinity 8?

Good question. The smart

Good question. The smart coils work with a 0-5V signal (0V when resting and a brief 5V pulse that signals to charge the coil),  which is different than the OEM BMW E46 coils. Wire the smart coils directly to the Coil output pins on the Infinity ECU.

 

For reference, the adapter harness coil output pins send a different signal to the OEM BMW coils, it will be 12V when resting and a brief 0V pulse to charge the coil. This is sometimes referred to as a 'dumb coil'  or 'direct fire' setup.

Thanks for the reply.... I have a couple of other questions on the Infinity in terms of wiring, config and tuning. Do I email EMSTechnical or just PM here?

I would recommend to email

I would recommend to email emstech@aempower.com .  I think it's difficult to find PM's on this forum.
