no performance difference (and there shouldn't be) I'll run it like that
and see if it resolves the flickering light issue.
EDIT: Made a couple of logs today and after looking at them I am of
the opinion that the flickering does correspond to the pump "simmering"
due to the pump relay being intermittently triggered. And as I have a
spare non-PWM AUX output I think I shall try using that to trigger the
pump relay e.g. turn the pump ON @ 18% and OFF @ 14% IDC. This
will ensure that the pump turns ON without simmering.
The blue light and the transistor in the HSF-3 that turns on the relay
will still be twitching, but I don't think that will cause any harm ??
The only unknown and possible flaw with this plan is that the HSV may
still be twitching, and that may not be good ??
The reason for changing plans is that I only recently finished rewiring
the ignition setup for individual coils and sequential firing. I would prefer
to keep that setup if this new plan can protect the pump and relay from
the intermittent triggering.
