Sort of non-EFI, but it is '727 controlled.... Friend of mine has a '91 Grand Prix, just got theft recovered missing about 90% of interior. Installed a new dash but the mileage doesn't match, duh. (reads 170k, was 90k). Any easy way to correct this? I assume the mileage is stored in either eeprom or flash in the dash itself, since I know the '727 can't. -> Bob Valentine -> bob@tecmark.com
