I've done a search for this and am now more confused than before. I am not new to flashing ECU's as I am a tech that's been doing it for some time. Using OE tools, as well as J-2534 boxes, I have never had a failure outside a few ford 6.0 FCIMs being bad out of the box. This is however my first attempt at tuning, not doing anyting crazy, just cags delete and whatnot on my personal vette.
My concerns are these:
1. It seems with the MPVi2 it is not recommended to have the laptop plugged in to a good wall outlet, yet it is also recommended. Is there a clear concise answer to this?
2. Using a battery charger hooked up to the battery while installing tune, good idea or bad?
When flashing modules on vehicles with OE/J-2534 stuff, I have always used a battery charger, a good one of course with a flash program function to provide steady voltages. Most service manuals actually instruct to use them.
Honestly do not want to brick any modules, especially not due to low voltage. Any info on experiences and/or recommendations would be most helpful. Thanks in advance!
