This might seem very elementary but how can you tell if an ecu is chipped? I have a OBD1 ls ecu, code is 37820-P75-A51. I thought it was stock, until i opened it up and it has a sticky label on the external rom chip that reads 274TB0.85K
Any ideas? TIA, josh
 
Looks chipped to me man. If you wan't to unchip it, go to PGMFI.org

You clip a jumper and it's back to stock. ;)

Cut the J1 jumper to revert back to stock.
