Hey how did you make out with this? Is it a pain in the ass? Which ones did you go with?
I didn't, I just deal with the noise. Occasionally add lithium grease and go about my day. [emoji1745] I'll probably have it fixed when it gets inspected in March

LED conversion. Switch backs, euro yellow fogs, 194 corners front and back, reverse, tail/brake/turn and license plate. Dropped the extra dough on the LASFIT canbus. I got super excited as I was testing with hazards and no hyper flash. Went for a drive aannndd hyper flash after 3 blinks.
I don't really want to add a resister but damn $195 for a BCM flash.

I will have to watch it. I guess I can pull the top plug on the T-Case and see how much is there.
After a bit of driving yesterday I noter the trans temp only got to 100 or so because the ambient was -3. So I am betting when I checked it the other day it wasn’t much warmer. It might have been a little low. Now, at 100F it is just at the bottom of the hot hatch marks. It’s fine.

I added resistors and more resistors on my 08 Silverado and never solved the hyper flash. I could get it to stop when the headlights were off, or when they were on, or when the brake lights were on, or when they were off, but never all at the same time. Maybe it’s because it has 2 turn signals bulbs in the headlights or maybe it was the aftermarket tails but I tried different resistances in different configurations and still failed. The damn bcm outsmarted me every time. I bought the bcm tune from BT Dieselworks and used my Autocal to flash it. It was driving me crazy. There’s a few mods available too when you do it. If you go that route, be aware he doesn’t really have any customer service so you have to be patient.

I put lasfit bulbs all over too and it hyperflashes. Couldn’t get an answer about the bcm tune but I believe it’s more than 200.
