Just received and fitted a new Nitro X Fuel Commander today from Ebay for my Z750 (delivered from Athens Greece of all places!) this thing ROCKS!!!!!! It does everything it says it does on the site. I just switched the dip switches to 100% and held on! the front just wanted to go skyward. there are 15 different programs you can use but i don't know why you'd bother with the other 14 coz the main reason for getting this is to squeeze as much power out of the Z as possible.... anyway check out the website (ebay online shop) and see for yourself. it only cost $69, a bloody bargain if you ask me. and no mucking around with laptops and dynos all day trying to set it up right. it just connects with 2 wires to the 2 airbox sensor wires...thats it! and you dont plug the sensor back in..
good luck.
