5 COMMON QUESTIONS

"When I connect the tuner to the vehicle, it doesn't power on."
Check for blown fuses for OBDII/Cigarette Lighter.
"Does the tuner have to stay plugged in to keep the vehicle tune?"
No, after tuning, you can disconnect the programmer.
"Can I stack/combine the SCT programmer with another chip or module?"
No, all Chips/Tuning Products must be removed before tuning with SCT.
"Can I tune more than one vehicle with this programmer?"
Yes, you may return to stock and tune another vehicle up to 5 times. However, only one
vehicle can be tuned at a time.
"Can the vehicle be tuned while the engine is running?"
No, this can cause severe damage to the vehicle and PCM.
"Should I return to stock before taking my vehicle to the dealer?"
Yes, this prevents the X4 from becoming locked if the dealer updates the PCM.
"Can I use a lower octane fuel than the tune file lists?"
No, you must use the same octane fuel that the vehicle is tuned for. Failure to use the
proper octane can result in severe engine damage.
"I have a supercharger / nitrous oxide on my vehicle, can I use a pre-loaded tune
on my X4?"
No, the pre-loaded tune files within the X4 are designed for minor performance
modifications such as cold air kits, high flow exhaust systems and other basic
modifications. For high horsepower modifications such as superchargers, nitrous oxide or
turbo systems, you will need to have your vehicle tuned by an SCT Custom Tuning dealer.
