FoxFlash Voltage is Unstable Solution

Problem:

I am having an issue. Just got the foxflash unit. Trying to read an ecm.

It starts out with 12.3volts, I get the leave power on message and connect to internet message then 30 seconds later I get the error message.

About 20 secs in to it the voltage drops down to 7.7volts, after I get the error message the voltage goes back to 12.3

Is the equipment no good?

CP18 ecu needs power at least 13-14v due to large power capacitors.

You will need to invest in bench variable power supply like most tuners use, this tool also require 24V for some Argri + truck etc.

Power supply must be rated for voltage, you can find bench 0-24v 5amp quite cheaply like amazon.

For example in foxflash bench box we connect 24v here.

Customer’s feedback:

OK….Update…. I put the 14v in fox flash. Hooked up a bench power supply, and set at 14v. Worked perfect! Thanks!
