Adding a "black Box" or "Gizmo" is very different (and much easier) than reprogramming the ECU... I have been listening to this "program the ECU" for over 3 years now...I have to say nobody I know has really cracked a BRP ecu that has really made any performance gains..if they say they have, I for one don't believe it and two would like to see the proof. Adding the Gizmo takes 10 seconds (once the Gizmo is programed with your VIN by BRP) and so getting one has become pretty difficult since BRP cut off Adam at Airdam Clutches unless you are a BRP authorized racer. BTW, a black box doesn't add any performance.. is just removes the Shaft saver function, speed limiter...and reduces a number of the safety factors built into the BRP programing like allowing the vehicle to run outside of the standard BRP parameters before sending into Limp Mode, and a few other things which I have provided more detail in the past on the Commander forums. The BRP program for the Maverick is more more performance oriented than the Commanders...but many have tried to crack that code...but its pretty evasive, even for the very best...I know some are getting closer but BRP is holding tight reigns on the code.
