I have a .bin file that has the incorrect gear ratio and I don't have LT1 edit to change it. If I send you the Bin file can someone change the gear ration to 3:42 and also disable the pass key secuity system? I have the flash program and can upload the bin file once its correct. Thank you

 

what year is it? if it is a 94 or 95 lt1 send it to me and i can set it for 3.42's, and no VATS. anything else?
