Corvette Predator Programmer

The C6 Corvette DiabloSport Predator Programmer is a state-of-the art, high performance tuning flash programmer in a sleek handheld design. Once connected to your C6, Z06, or Grand Sport Corvette, the Predators internal computer recognizes the PCM and automatically picks the proper tuning files designed specifically for that PCM. Inside the Predator’s memory are the actual tuning files that optimize spark timing and air/fuel ratio curves. Unlike other “tuners”, the DiabloSport Predator programming is performed in very small increments throughout the entire RPM range, for a smoother, wider and more predictable power delivery. DiabloSport engineers spend many hours on the dyno, street, and track to ensure the tunes provided with the Predator are the best they can possibly be for your Corvette.

Installing a DiabloSport tune on your Corvette using the Predator Programmer is simple and only takes a few minutes. You should know that the very first time the predator is used on your Corvette it will automatically create a backup of the original factory tune. If your Corvette has previously been tuned you should proceed with caution as serious engine damage can occur if the Predator tune is installed over a non-factory or aftermarket tune. We recommend having a Chevrolet dealer reflash your Corvettes ECU (Engine Control Unit) to its original settings so there will be no possibility of damage to your Corvette.

Before starting to install the tune be sure that your Corvette is parked and the engine is off. All doors must be closed and all electrical accessories must remain off. To install the tune, plug the Predator into the diagnostic port. The predator will recognize the vehicle and then give the options of performance tune, diagnostics, or options; select performance tune by pressing the continue key. After reading the disclaimer you can now turn the ignition on being sure not to start the vehicle. Next highlight the type of tune you would like to install and follow all prompts to turn the ignition on and off. While the tune is being written, be sure not to interrupt the process or ECM damage can occur. Once completed, you simply unplug the Predator and cycle the key to start your Corvette’s engine. The predator also contains several DiabloSport tunes that have been tested and approved by their engineers. You can install your choice tune as is or you may customize the tune to meet your wants and needs.

If you are planning on having your Corvette serviced it is recommended that you restore your Corvette back to the stock tune. This can be done at any time using the restore feature on the Predator. No need to worry if you have customized the tune as it will be saved for future use.

Today’s Corvette technical question comes from Jim, who owns a 1990 Corvette:

I have a 1990 Corvette convertible with 350 and 6-speed that I can only drive when the weather is cool because I cannot get the cooling fan to run. The fan motor is good (works when voltage is applied) and I have replaced all of the temperature sensors and the cooling fan relay, but still no fan operation. What else could be preventing the fan from running?

Answer: Your Corvette’s main cooling fan is controlled by the PCM. The PCM sends a ground signal to the fan relay when it sees the desired temperature to run the fan has been met. You need to check the relay and make sure you are getting your battery 12V and ignition 12V when the key is on. With the key on, jump the ground wire in the relay. If the fan turns on, you have an issue in the PCM and it may be time for a rebuild. If it does not turn on, then your problem lies in the fan circuit between the relay and the fans.
