Help with holley terminator x max Hey guys, I was trying to update the firmware in the handheld and ECU yesterday and now the ECU has lost power and none of the lights come on. The handheld still has power but says it can't locate the ECU. Has anyone experienced this or any guidance as to what it could be?

I'm having trouble with the same.
initial power up (term.x max) still need to load base tune (input basic motor info).
I have power to the handheld, but the handheld says it's searching for the ECU.
I connected the handheld is directly to the ECU (I removed the dakota gauge splitter).
So, the ECU is connected directly to the battery and the powered up handheld is connected directly to the to the ECU, but it still says that it's searching for ECU (wtf?)
I know I've gotta be like one wire away from hearing it run...
Thanks in advance for any help

Also No lights On on the ecu itself.
rechecked power sources/connections, re-inserted handheld connection (unplugged/replugged) still by itself in plug, just rechecking All.
The handheld was just replaced (by holley) as it was defective out of box (making me wonder if ecu itself is bad out of box too).
S happens :-/

You may have a bad ECU. It's not super common, but it does happen.
