2024 Plat BC 1.4 Upgrade

Yea, but it's not the same ABG. Notice on the Mach E it starts with a T which is a 2026 part number. The both firmwares may end with ABG, but they are very VERY different.

Yep, was more of a trivia than anything

My 100A charger should arrive tomorrow... I might pull the trigger on updating the mache. Most updates seem to be lightweight except for that driver camera something something that took 1h+ on my F150.

Interestingly, there are 4 separate door modules on that one (vs only 2 in 150). Her previous mache (2024) spent 2 months in the shop due to issues with door handle, so I might want to keep those ones up to date.

CMR will most likely take 45-60 minutes on the Mach E too. I've done a CMR update on a Mach E with my 20amp power supply and it was fine, but to future proof yourself whenever an IPMA update comes out, I would just go with the bigger one.

Got the 100A charger with 8AWG cables, will start with smaller upgrades first to make sure they don't get too hot.

It seems I'll need to remove the 2 frunk panels to get to 12V. I'm connecting to those exposed posts and not the battery directly, right?

Oh no. The EV's have a tiny 12v battery. You need 40amp or bigger for those, so might as well get the bigger one which will work for both. Many people on the Mach E and Lightning forums have used this one with success:

You will just need a set of jumper cable to cut the ends off and adapt it to the power supply so you can connect it to the battery.

Used one like that, worked perfectly and also works for my 911 gt3 if I’m doing any coding

Got the mache upgraded, no issues except for the "Stop safely now" popping up on the dashboard... All DTCs are gone, every module showing green, and yet still this message won't go away. Not sure what to do with it.

You'll want to connect the negative to the BMS sensor

Message me the VIN and I'll check it out tomorrow.

I did message you, however after keeping the car off for 30 minutes, the error went away. Fingers crossed it stays that way.

UPDATE: Drove it around this morning and so far so good
