**NEW BATCH/VERSION v1.3**

This works in any obd0/obd1 or other ECU application where 28 pin 27SF256 or 27SF512 chips are used.

The old-style SST chips are no longer made, resulting in a lot of Chinese knock offs that don't work, or are only writable once. These new chips are a different format that we had to adapt to the board that lets it plug in the normal socket, in addition, we decided to make it a 2-timer as well because the chip has twice the storage of the old-style chips and can store 2 separate tunes on one chip.

Simply use the jumper on the board to change tunes, or hook a wire to the center pin to a switch on your dash, and the other side of the switch to ground and you can change tunes at the flip of a switch!

COMES WITH A BUILT-IN CHIP. THIS Replaces the old style chips and is direct plug-in compatible

Instructions: (MORE DETAILED INSTRUCTIONS CAN BE FOUND HERE)

Place jumper on pins #2 & #3, which is Tune position #1 it will read from the normal part of the chip.

Place jumper on pins #1 & #2, which is the extra portion of the chip, it will read the second tune.

Instead of using the jumper on board, you can use a switch wired up to the center #2 pin, wire the other side of the switch to ground. Anytime you toggle the switch it will change to the second tune, (Off position on switch reads the normal tune)

NOTE: PLACE IN THE ECU WITH THE NOTCHED SIDE OF BOARD FACING ECU PLUGS.
