in the programmer and reinstalled into the vehicle’s computer. This process returns the computer to factory
stock and resets the programmer to allow the user to reprogram the vehicle AFTER repairs or service.
Why Is It Necessary To Return To The Stock Tuning?
The reason that this should be done is because the factory diagnostic equipment will only recognize factory
calibration information. If that information is not stored it will automatically update the vehicle’s computer to
the original calibrations or to the most recent updated version, erasing the optimized tuning and other adjustable
features that were installed by the programmer.
Reprogramming The Vehicle After Service Or Repair
After the vehicle has been serviced or repaired, you may retune your vehicle. If the factory has reprogrammed
the vehicle with a calibration that is new and not recognized by the programmer, the programmer will display a
“Update Required” message. If this occurs, the user will be instructed on how to update the programmer. This is
a safety feature of the programmer. We do not want to rewrite any information if it is different from the
calibrations currently stored in the vehicle. Following the instructions will allow the vehicle to have the latest
and most current performance calibration that will match the updated factory version. Call the tech service line
that appears on the screen for instructions on how to update the programmer. Due to the factory update of the
computer, the programmer will have to be upgraded to match the new calibrations that have been installed in
the vehicle’s computer. There is no charge for calibration updates.

VEHICLE NOT SUPPORTED
The following message is displayed when the programmer does not recognize the vehicle, along with an error
code:
“THIS VEHICLE IS NOT SUPPORTED FOR PROGRAMMING; CALL HYPERTECH AT [phone]”; Code
0137, Code 027B, Code 0300
Verify that the vehicle year/make/model/engine shows to be supported with the programmer part number. The
part number is located on the label on the back of the programmer, and on the end of the box. If the vehicle is
supported, the programmer may need to be updated to the latest revision to work on your vehicle. See Section 5
for instructions on how to update your tuner.
LOSS OF COMMUNICATION
The following message will appear if the programmer is unable to communicate with the vehicle’s computer.
“AN ERROR OCCURRED DURING VEHICLE PROGRAMMING; CALL HYPERTECH (800) 532-335”
Take these steps to correct the problem:
1. Make sure that the ignition key is in the RUN position and that the engine is not running.
2. Make sure that both ends of the cable are securely attached.
3. Wait at least five (5) minutes for the programmer to re-establish communication before restarting the
programming process.
4. If the three (3) steps above do not correct the problem, call Hypertech tech service line on the phone
number that appears on the programmer screen.
CABLE REMOVED WHILE PROGRAMMING
The programmer will lose power during programming if the cable is removed for any reason. If this happens,
simply reconnect the cable, and follow the messages on the programmer.
