ATTEMPTING TO PROGRAM A DIFFERENT VEHICLE

Code 0125: VIN Mismatch will appear if attempting to program the computer in another vehicle without first

programming the last vehicle it was used on back to stock. Return the previous vehicle back to stock, following

the Back To Stock procedure in Section 2.

UPDATE REQUIRED

There are several instances where an update may be required to use the programmer. The following codes

require an update. The programmer will display a message that it needs to be updated. The programmer can be

updated via the internet using the Hypertech Tuner Update Software, and the supplied USB cable. See Section 5

for instructions on how to update your tuner.

Code 01C8: Stock calibrations not supported in programmer

Code 0128: Needs preloaded tune (2011- up GM Duramax diesels)

BLANK SCREEN

If the programmer does not power up, make sure that both ends of the cable are fully inserted. If the

programmer still does not turn on, check for a blown fuse in the vehicle fuse panel for either the cigarette lighter

or the accessory circuit. Replace with the proper amperage fuse.

3-3: Tuning Features & Options

GAS ENGINE TUNING

This option installs the Hypertech Power Tuning, based on the octane of fuel your vehicle is using. Hypertech

Power Tuning is a rigorous procedure that maximizes performance by optimizing the engine’s air/fuel ratio and

spark timing. Hypertech Power Tuning doesn’t just focus on the power you’ll gain at wide-open throttle. The

engine performance under normal driving is also optimized. This means that there is no need to switch between

a performance, economy, or tow tune.

OCTANE LEVELS

Regular Fuel = 87 octane minimum

Premium Fuel = 91 octane minimum

PERFORMANCE

Hypertech’s full spectrum tuning optimizes the power curve point-by-point, at all RPM’s and throttle

positions. This tuning method takes hundreds of dyno pulls for each vehicle and further testing is done at

the track and on the street to ensure maximum horsepower, torque, and throttle response for just off idle

to wide-open throttle, while maintaining safe engine and drivetrain parameters.

Higher compression ratio engines and engines with superchargers or turbo chargers were designed to use

only premium octane, so only one (1) Power Tuning program for premium octane is provided for most

vehicles. But, if your car or truck came from the factory capable of using more economical regular

octane, then two (2) optimized tuning programs are provided: one for premium, and the other for

regular. In most cases, Hypertech’s exclusive Power Tuning for regular octane provides excellent power

gains, almost as much power as premium octane. If you are using premium octane, and you want all-out,

maximum power, then select premium octane Power Tuning.

Some vehicles come with the option for (2) premium tunes, one for 91 octane, and one for 93 octane. On

these particular vehicles, there was enough measurable gain from 91 to 93 to offer both options.

FUEL ECONOMY

Hypertech engine tuning is more efficient, and the added torque during normal driving gives an even

better throttle response. With the engine creating more torque, you use less throttle to maintain cruising
