When engines started to become complex and computer controlled, a lot of guys thought it was the end of working on your own truck. From now on, they figured, it was a dealer job and all they would be doing is changing the oil, if that. Boy, were they wrong! The neat thing about computers controlling everything from ignition curves to fuel injection and sensors all over telling the computer exactly what was happening at every moment, is it’s easy to find out if the changes you just made were for the better.
Remember the old days? You buy some headers for the engine or a new carb, bolt them on and you believe you added horsepower, but did you? How would you know? Unless you have a drag strip handy to compare before and after timeslips or a chassis dyno to measure output, you’re just guessing. You might have lightened your wallet and slowed down your truck, not such a hot combination. Computers change all of that. At least they can, but you have to be able to see what they see and make adjustments, otherwise it’s a black box under the hood and you’re not allowed in.
Hypertech started back in the ’80s with replacement chips for onboard computers. They did all of the reprogramming and you bought a chip to swap out. It did the job and everyone was amazed at how well they worked. In the ’90s they they came out with a Power Programmer which has been the best thing you could use to instantly add power because you did the reprogramming yourself by pushing a few buttons. Now comes the
HyperPac Performance Computer. This does everything the Power Programmer did plus adds that dragstrip and dyno you didn’t have and it can diagnose troubles, too. Cool.
The Hyperpac is a small electronic box with a 3″ by 4″ touch screen with very easy to follow menus for performance tuning, monitoring your engine, running down a virtual dragstrip, checking power on a virtual dynamometer or running engine diagnostics. It straps to your visor with elastic straps or mounts to your dash with a cellphone mount. To connect it, you plug it into the engine diagnostic port under the dash, that’s it! It can’t be any easier. If your late model truck has one of those OBD (onboard diagnostic) plugs, you’re probably all set.
If you always dreamed of having a complete shop where you could tune your truck for ultimate performance and see the results at the strip and on the dyno, now you can and the whole thing fits in your hand! Very, very cool.
