ECU module programming guide using FDRS

yeah I wouldn't do anything less 75amps since the battery is tiny and those updates can draw 60amps+ for several hours. Some have piggy backed two PL2320s and still had the update crap out. You "might" get away with it by making sure the 12v is fully charged and you're only doing one non-usb update but not sure I'd chance it for a few hundred dollars. I used a Powermax PMBC-75 (~$300) when I did my 6hr+ marathon. The 100 amp options range from a little over $400 for the clore pl6100 to $500+ for the shumacher INC100.

There are cheaper options out there that work. Maybe someone else can chine in with what they used; or check the FDRS thread on the Mach E forum for other options. I know @Mike G used two Clore PL2320's at the same time for a while with success.

I believe You can piggyback the Clores. Several on Mach E Forum have reported this with success.
