I’m thinking about buying an external power supply for flashing ECUs. I have found many expensive and one in lower price.

Will this one be ok for the job?

Hi,

For an off-the-shelf solution, this looks very capable. I would certainly trust that to deliver the needed power for any modern car, given it has a 100A rating.

Another option, if you are handy with electronics would be to re-purpose an old server PSU and configure it to run at a little more than the usual 12 volts. These can be had very cleaply on ebay ($20) but would be a bit of work to configure appropriately. I'll likely be doing this fairly soon, and will do a write up of the build, if people are interested?

Cheers
