hey calum, got the bin you sent me this morning, it was 24kb in my email and when i saved it to hardrive it is now 32 kb? just wondering what the file size should be, last time i ended up having a corrupt file and was the whole reason i couldnt tune i just cant remember how big the BIN is supposed to be, thanks man!

As long as it is for an OBD1 car you should be fine.
