ECU Information

The Super X uses the Sagem MC1000 ECU. The tune information is held in a non volatile flash memory chip. When you download a tune you are "reflashing" the memory. There are several parameters also held in non-volatile memory which do not change when a tune is downloaded. They are Leakage (long term fuel trim), Closed throttle trim, and IACV stepper trim. These values can be updated using the "Real Time Monitor" within SuperXtune.
