Injecting with IDC vs MAP signal

[crum86]

Just wondering if there was any difference using idc or map as the trigger source? Does either have a bigger advantage over the other at all?

I've currently got my HFS3 wired into idc on my Haltech PS2000 and found the system wasn't activating. The system was working fine with the previous EMS ecu. Would there be a difference in idc signal between different ecu's? The alternator was also having issues at the time so I'm unsure if this was contributing.
