I bought a 424 ecu from ebay and it has a BFPL memcal in it that does not apear to be tampered with (black base knock filter board and sticker still on eprom)so I read the bin and used the id tool and it is not recognised then compared it to the bfpl bin in the id tool data and it is totaly different
can some one shed some light on what the bin actually is

bad read by the looks of it 1 or more pins not connecting

read it again and all good How did you know it was a bad read?

Recuring strange data over and over again when viewed in hex editor

thanks
