ICM and ECM
Thanks. Bought a new ICM today and plan to install this evening. The last post, however, has me puzzled. I have read so many post overs the last two days about coils, distributors, ICMs, and ECMs, SSIs, and MPUs. If the ICM is the part below the coolant reservoir that "controls" spark even after a Nutter bypass, then I assume the ECU is the part on the passenger side above the heater that no longer has any purpose. It is unlikely I will take time to remove it but it would be nice to know whether I need to even think about it in the future if I have another problem. Thanks for the help.
