Just a thought and I don't know if it is relevant. But prior to installing the
larger injectors I was providing a PWM signal that mimiced IDC from an aux
output on my ECU. I changed this to a direct IDC pickup from an injector
negative because I needed the aux output for another purpose.

Thus there will now be a back EMF spike reaching the HFS-3 controller that
was not present previously. Could this cause the light to flicker before IDC
reaches the trigger point for W/M injection ??
