Hypertech HyperPac Review
It's Saturday morning.
The new performance parts you bought are sitting on the shop bench. You can't wait to get to the garage to install them and go for a ride. You're eager to see the power gains and feel how much more performance they'll produce. So you do the installation, jump in, fire up the engine and head down the street. The road's clear, you stab the throttle and...yep! There it is! You can feel the difference, and the engine even sounds more powerful! But wouldn't it have been great if you could have put it on a dynamometer, base-lined the horsepower and torque before installing the new parts and then tested it again to actually measure the power and torque gains? And wouldn't it also have been great if you could've gone straight to a drag strip, right then, and not wait 'til the weekend, or next year, to see how much quicker and faster your pride and joy had become? In fact, don't you really wish you owned your own dyno and drag strip?
Well, now you can...the HYPERpac is here! Kept under wraps until November 2, 2004, Hypertech introduced the HYPERpac (Hypertech Performance Automotive Computer) in Las Vegas at the SEMA show. An instant success, the HYPERpac won awards for the "Best Engineered New Product" and the "Best Performance-Street Product"... the first time in SEMA show history that a single new product had won two awards. Plus, all the 30-minute performance automotive television shows were there, waiting in line to video and learn about the HYPERpac for their shows. For virtually everyone in the industry, including the SEMA judges, the warehouse distributors and the media, the HYPERpac was the talk of the show.
Why all the excitement? Simply put, it's this: The HYPERpac is an actual computer, designed with tremendously useful and fun programs already loaded...with more programs coming. Of course, the HYPERpac contains optimized engine tuning programs as Hypertech Power Programmers have for years.
But what was really new, created all the buzz and led to winning both awards were the Dynamometer, Drag Strip, Engine Monitor and Diagnostics programs... all bundled together and available at the push of a button from the HYPERpac's Main Menu touch screen.
Plus, the simplicity and ease with which the programs can be used, in combination with the accuracy of results, impressed everyone who spent time working with the demonstration units.
Revolutionizing The Way Automotive Enthusiasts Will Evaluate Vehicle Performance
Packed with five distinct programs, the HYPERpac brings a fresh, simple and precise collection of methods to evaluate engine and vehicle performance. Based on years of dynamometer and dragstrip testing experience, the HYPERpac is so easy to operate that no instruction book is really needed. Simply make a run and the unit automatically records, calculates and displays the performance data every enthusiast wants and needs to know. The touch screen shows only the buttons that apply to the screen being viewed, eliminating cumbersome button combinations and multiple operations to navigate the programs. A Smart Keyboard™ or number pad screen appears automatically but only when needed to enter notes or other information.
Basic installation of the HYPERpac is easy. Just slip the straps through the HYPERpac case's back plate (provided) and over the sun visor, connect the cable to the vehicle's diagnostic port (DLC), press the "power on" button and select a program from the Main Menu. That's all there is to it! (If desired, the HYPERpac can be mounted on the dash with most universal cell phone mounts.) So... let's take a virtual tour of the HYPERpac, and its many features. You'll be astounded by what it can do!
At a touch of the HYPERpac screen, Performance Tuning provides all the features of Hypertech's legendary Power Programmer, including the most powerful, 50-states street-legal Power Tuning available, and two fuel programs; one for regular and one for premium. Diesel owners can switch between any of three different horsepower levels. And for all trucks, Hypertech Power Tuning is developed for the maximum towing weights allowed by the manufacturer. The Performance Tuning program also allows adjustments to the following:
The HYPERpac also allows a complete review of all performance selections on a single screen, before re-programming the vehicle, or to review currently programmed selections.
Select Drag Strip from the main menu and a screen appears displaying a Christmas tree. To the left, Engine Monitor appears showing various engine conditions in real time. You can preset the functions you wish to monitor as you make a run: air/fuel ratio, coolant temperature, spark advance, and engine knock would be good choices.
Engine Monitor also allows you to watch the variables that you need to control to make consistent runs, especially coolant temperature and RPM, vitally important when testing before and after modifications have been made.
On any safe and legal piece of asphalt long enough to make a run and slow down safely, you stop the car. Once you achieve the right coolant temperature and bring up the RPM, press the Start Tree button on the lower right. One second later the tree will start down, in half-second intervals, just like at the track. Leave the line when the last yellow comes on, as a first guess, and start the run. At the end of the run, an audible "beep" will be heard, and the Hyperpac screen will flash "END RUN". That's it.
Now a whole bunch of good stuff has happened, but you will have to stop the vehicle before you can see the results. The Hyperpac will not display test results while you are in motion...the temptation to check out the results while barreling down the road is just too great. After slowing to a stop, your "time slip" will appear. Press Road Test on the touch screen, and a table showing the zero-to-whatever speeds appears. Press Drive Wheel Horsepower (Yes, it also works on front wheel drives.) and a table of Horsepower verses M.P.H. is displayed.
Since the Hyperpac knows the ambient temperatures and pressures, the values displayed are almost exactly correct. Almost, because humidity is not measured by on-board computers, at this time. You can measure the humidity and enter it for perfect results, but the default position stored is 50%, a reasonable number for most locations.
Want to see the graph, just touch View Graph below the data table. And finally, touch Data Acquisition to see the stored variables, just like on expensive engine dynos, and unavailable on chassis dynos.
Suppose that you thought you heard engine knock during the run. Look down the Knock column and determine exactly the rpm, air/fuel ratio, and the spark advance at the moment of knock. Knock shows how much spark retard was needed to relieve the knock. Check the air/fuel ratio to make sure the engine wasn't running lean, and look at spark advance to see if it is reasonable.
Another unique feature of the HYPERpac is that everything you just saw, every screen, has been automatically saved! Later (if you choose) you can transfer all the runs and data (which are dated and time-stamped automatically for you) to your personal computer to compare tests, or to print color printouts of dyno curves and tables of power and torque values, along with ambient conditions and any notes that you made for that test...exactly what you could previously only get from a professional engine dyno facility. And all you did was start the tree and make a run. Now you can stage the car, touch Start Tree, and do it all again.
There are times when a standing-start-quarter-mile run is not possible. No problem... Dynamometer allows testing "on the fly". That also means that you donít have to go very fast, just whatever speed corresponds to maximum RPM for the test in 2nd gear, giving you more safe options on when and where you can test.
Although you can test in any gear you choose, 1st gear will show less power and torque than higher gears. Think about it this way. If you are in neutral at idle, and whack the throttle, letting off at the RPM red-line, how much power did the engine deliver to the driving wheels in that half-second or so? None! It took every bit of the power produced, from idle to valve float (if you're not careful), just to accelerate the crank assembly and flywheel (or converter for automatics) from low to high RPM.
Ideally, you would like to test in the highest possible gear, but that would mean outrageous speeds and only at the Mid-Ohio test track could that be done safely. So, use 2nd gear for all testing, and you can do it almost anywhere, safely and without exceeding the speed limits. To run a test, place the shifter in 2nd gear, and slow down to the RPM from which you want to begin your test. Touch Start Dyno, and then stab the throttle, accelerating all the way to the maximum RPM that you choose. Touch Stop Dyno, slow the vehicle to a stop, and review the results. Touch Engine Horsepower to view horsepower and torque as a function of engine RPM. Touch View Dyno Graph to see that same data as smooth plotted curves. Touch Drive Wheel Horsepower and view the power at the driving wheels. And finally, view engine and ambient conditions by touching Data Acquisition.
The Engine Monitor displays real-time engine operation conditions, like air fuel ratio, ignition knock, spark advance, R.P.M., oil pressure, engine coolant temperature, and much more, all user selectable from the menu.
To record displayed data, at the track or just driving down the street, touch Start Recording and when ready, touch Stop Recording. All data is automatically saved for later review. Engine Monitor allows you to see virtually everything that is going on in the engine, displayed in digital format, or as analog gauges, best for RPM and other rapidly changing variables.
Diagnostics gives the user the ability to properly diagnose a problem without owning expensive shop tools and service manuals. The program not only displays any Diagnostic Trouble Codes (DTCs) that the vehicle computer is reporting, but unlike most aftermarket diagnostic tools, the HYPERpac gives the user a complete description in plain language of what the codes mean. After making the necessary repairs you can clear the codes from the vehicle's computer to turn off that check engine light.
Some Concluding Thoughts: So now you know why the HYPERpac won "Best Engineered" and "Best Performance-Street" Awards at the 2004 SEMA show and why we've gone to so much trouble to introduce this hot new product to you ó the midnight oil was burning from Tennessee to California. What is so amazing about this device is that you can pump up your engine's power with Hypertech Power Tuning, and use the HYPERpac's Dyno and Drag Strip programs to test and measure power and performance gains. Plus, you can store and print all the results. And all the while, you can monitor the engine's vital information and diagnose and clear any trouble codes that may appear.
