If you have Revo software you can use this to enable/disable performance mode, select fuel grade, enable/disable anti-theft mode, etc for your Revo flashed ECU.

I bought this only a few months ago for my Revo'd S4 but have since moved to K04s and GIAC. It is in like new condition with original box, manual, etc.

Price includes shipping as long as your are in continental US.

Note: This will do *nothing* for youif you don't already have Revo software flashed on your ECU!
