Dashboss installed...do I have a FICM problem?

I finally got my Dashboss last night and it's awesome. I sat out in my truck in 14 degree weather just tweaking the gauges, etc. It was freezing but worth it. Anyway, I saved a log file of probably less than a minute, but during some testing before that, I noticed my FICM would briefly drop in the 45 range. However, during the time I did record, it never went below 46.5. Do I need a new FICM? The truck was running during this test.

Dropping to 45v right after a cold 14* temp start up, while glow plugs are running could be batteries on the weaker side.

I would get the batteries load tested first to see if they are in good condition first. Most chain stores provide this service free. If the batteries test out good, might want to check into a new or repaired FICM.

I'd be monitoring the FICM but at those extreme temps I wouldn't freak

most FICM's seem to start to fail with a low output when cold then eventually climb after a while

Ok, I never did move off the spot, so I thought I'd try to monitor it while driving to see if it made a difference. At least it's not hovering at 42v or something constantly. I'll keep an eye on it. Thanks for the input. I've heard of Swamps and Ed at FICMrepair.com. Would those be the guys everyone recommends?

I should add that all last weekend, I let the batteries sit on the trickle charger and I had the block heater plugged in for 6 hours before I fired the truck up. I had the whole log file added, but it was so much text and I hated to be a tool about it, but there is nowhere to attach a .csv file and I don't feel like uploading a pic of the spreadsheet log file.

mine was hovering around 42 for the first 20 minutes so I went with the bullet proof 6 phase

the repairs are ok but it still can fail again so I went with the improved version since I keep my stuff for a long time

LOL!! I still haven't figured out how to attach PDF files to a post, or even figure out how to convert the CSV files to PDF!
