I want to replace the ecm in my 1998 corvette with a backup ecm I have
from a 1997 corvette both are licensed through hptuners. I will flash the custom tune I have on my 98 ecm on to the 97 ecm but what about the vin? Does that need to be changed? I switched them out but there was no power at the ob2 port? Could it be because the vin # does not match? Thanks
