You can now get a performance ECU for about half the price of a Ducati Performance ECU plus you have the flexibility to change your map whenever you need - with out sending your ECU to someone. This unit allows reprogramming of the Magneti Marelli 5AM & 59M units, Siemens, and the Mitsubishi/melco ecu's. The Rexxer can allow for removal of the exhaust control valve, O2 Sensors and on some bikes add cruise control. It also allows you check, read, and clear the check engine light and service indicator from your Ducati. Since the original map is stored on the rexxer, the maps can be switch back to stock. Once a remap module has been downloaded onto an ECU unit, data can only be transferred from this particular ECU unit. If you want to upgrade the map later because you have further modified or changed your Ducati you can do this by sending us the Rexxer unit for a new map. The ECU does not have to be sent in to us.

Sell your bike or want to return it to stock? Your original map is stored on the rexxer module (Magnetti only). Just plug it back into your ECU and swap maps. You can then install the Rexxer map on another bike, or change the map for use with a different model. Not planning to re-map another bike with it?
You can sell it loaded with a performance map to get back most of your original investment.
