	ECU has a piggybacked chip already? cant write to ECU « on: February 25, 2020, 04:23:47 AM »

Hey guys, i just purchased a spare ecu from someone and on the back in marker writing it says soldered chip zeus tune. He accidently sent it thinking it was a stock ecu for my 01 s4 tip car. I cannot flash a new tune to it, I even tried to read it and capture the bin file so i could it run it through tunerpro to see the parameters and find out if it was a Stage 1 or 2 tune but keep getting an error. Whats the deal with this ecu?

ok, so your saying a stock ecu should have no problem being flashed but if it has a piggyback like this one does then that must be the reason?
