FICM Voltage question

[Woodsracer]

I went a did a couple of WOT runs for a few seconds to check FICM voltage. The lowest I saw when WOT was 47.5 V... after I got out of throttle I saw 47 for a split second then went back to 48V... Normal??

Yup, you're good.

46-44v is when u need to worry.

my php tuned ficm hoovers at 49-49.5v on my edge cts insight

What is the advantage to the FICMs that you can buy that run at 58 volts.

More volts to the injector coils to make the injectors spool valves move faster.

more important than WOT, is cold startups

check when engine oil temp is 40F and under, thats when the FICM is in inductive heat strategy and will draw monster amounts of current. once EOT is at or above 130F the FICM only draws minimal current.

Mine was fine once warmed up but dipped in the upper 30's on cold start ups.

Went out this morning.. Temps probably in 50's already, started cold and FICM V only dropped to 47.5V.... Hope not to have to worry about that part of the 6.0 saga...

your good just keep an eye on it because it is not a matter if it will go its when
