New MM3 Installed - Couple Of Questions

[Jake Z.]

So, this weekend I installed my newly acquired MM3 as supplied by @DRD.

When first powering up the unit, I was expecting a firmware update (per other threads and videos I've seen), but I don't think that happened.

I'm presuming that the update was done prior to me receiving?

There was some sort of "Uxxxx" error at first, but I was able to continue on, agree to terms, use the VIN, etc.

Then, I retrieved the stock file which was so fast I almost wondered if it was even retrieved. I have since copied the file (approx 284b, I think) to my PC. So, I guess that's right?

After retrieving the stock file, I then loaded the custom tune, and all has been well during the 4-5 times I've driven the truck.

If all seems OK now, and I'm not getting any errors, should I just not even worry about that initial error? I seem to have the latest firmware with the "switch" function, etc...

Lastly, now that I can see the ECM voltage from start-up, is it normal for the voltage to hover around 12 volts for maybe 10-15 seconds and then jump to 14ish volts for the rest of the trip?

Just curious as to why it's not 14 from the start - does it take the ECM that long to verify proper voltage before applying or something?

No worries about the error.

The voltages you are seeing are normal.

If you want to make sure you have the latest firmware update:

Download the MM3 autoagent on your laptop (windows) and connect your SD card to the laptop using the adapter.

The autoagent will take care of the rest of the updating.
