    Default $0101 code when flashing

    I am new to using efilive but have read through alot of threads and have not really found the answer im looking for. Ive been trying to flash my truck with some ppei tunes and kept coming up with $0101. on one attempt it started to flash and activated vin license got to erase and then threw the $0101. Ppei had then sent me a stock tune file to try and same thing. then i took a spare ecu i had and tried flashing it with same end result. would take vin license say erasing then stop with $0101. im brand new to this so learning as I go but im trying to see if theres any hope if i put these ecus on a bench harness that they will hopefully flash without issue? mostly looking for input or advice from others if they have had this same thing happen.

    Ended up getting bench harness and was able to flash without issue.
