Default Odometer ???

I have a '91 ZR1, very low mi. 11,300. The car is clean, but not that clean. It appears to have a junkyard ecm, decals are unreadable. The Carfax is clean. Is it possible to clock these cars ? Where is the mileage stored, in the dash or in the ecm ?? Someone out there must know !

Ecm And Pcm.

Yes You Can Clock Them If You Change Out Cluster And Ecm.

Be Afraid

Mileage is stored in the CCM, which has a VIN lable attached. If you're really ambitious you can pull the CCM and see if the VIN matches.
