Ok - but it doesn't matter what is currently on the chip, I'll still be able to flash over it? Thanks again

Yes.

Ok, finally pulled the ECU. The ECU has been socketed, and the chip that it is there has a paper tag on the top with some handwriting on it. I still can't flash over the tune that's in there, but I can read the file perfectly fine. What's the easiest way to get around this at this point?

Obviously the ECU got chipped with aftermaket rom. It is probably not writable but I might be wrong. Any chance you can get socket version of whatever eprom chip you are supposed to be in there and just plug it in and then flash it?

AFAIK you can remove and plug new eprom in after the ECU boots itself up and the flash the new virgin chip via obd.

Yeah I was wondering if I could just source a stock/blank chip to pop in and flash.

If I buy this, then pop it in the socket, I should be good to go to flash it, correct?

Hello! I have the same problem. It fails at the same stage pf writing. I opened the ecu up, but didnt find any aftermarket chips. I have a 2001 S4 with m box. What could this be?
