Charlie Mornmot's `73 Corvette is not stock, featuring a complete '02 Corvette LS1 drivetrain. For all intent and purpose, this Corvetteis an '02 with all the standard computer hardware as well.

Our test installation took place onCharlie Mornmot's highly modified `73Corvette from Bismarck, Illinois, featuringa stock '02 LS1 engine and 4L60Etransmission.

The FAST-FLASH computer programmer hooks up to the standardCorvette computer diagnostic plug, which in the case ofCharlie's Corvette was hidden on the right side of the dashboard.Most OE plugs are located on the lower driver side ofthe dash like this one.

The FAST-FLASH is preprogrammedwith two basic tuning calibrationfiles: performance mode and economymode, which you can use to modifyyour personal computer preferences.
