If you want to use your BURN1/F2A combo to read the binaries off your stock EEC Computer, then this is the hot item! Allows you to power the EEC Computer on the bench via the USB port through the BURN1/F2A! No external power needed. Might even work in the car, haven't tested that out yet. Lets you read a full 4-bank EEC-V in less than 10 seconds. Item is shown in top picture. Bottom picture shows it in use with an F2A and BURN1 hooked up to a 2-bank EEC-V.
