Currently available tachs are just that, tachs. Some have the ability to replay a small RPM sequence, some can have an additional drive-shaft rpm signal, but that’s about it.

On the other hand there are currently available data-acquisition systems. Most of them require you to be an engineer to set up. Generally these are boxes, with no design whatsoever, that are preferably put somewhere where they can’t be seen. We have used data-acquisition systems in car-racing and have always felt that they have a fundamental flaw. The problem is that generally you don’t have access to the data when you need it most which is when it’s still fresh in your mind. It’s sort of like having a land phone and needing a cell phone.

Unless you have deep, sponsorship fed pockets and telemetry systems generally speaking your racing weekend will look like something like this:

Inevitably you’re still wrenching at 10 PM the night before. Finally you get to the track, the adrenaline being the prevailing force you somehow don’t feel all that tired. So you go out and do a couple of practice sessions (or passes) and gather some data. The only way to see this data is to hook-up a laptop. This means you need some form of power since the laptop batteries are only good for a couple of hours, that’s if you remembered to charge them. But the problems keep compounding, your laptop is really not meant to be used in a harsh environment like a race car, oily fingers, rough surfaces etc. Another huge problem is that most laptop screens can’t be seen in daylight which is a very annoying thing in itself. So finally you decide that it’s best to look at the data when you get home. Now the problem is that you can no longer relate the data to the actual events taking place with your car, like that noise it’s making or the reasons why it’s running hot etc. Unless you have a super-wife and she is baking in the sun and taking notes, (man that’s love) your data will have limited value. This is because by the time you get home the entire weekend will become a “memory medley” filled with emotional highs and lows, technical issues, racing mishaps, varying weather & track conditions and more. It will be nice to look at the graphs on the big monitor but in actuality it will be of little use.

Being frustrated with this Gtech decided to bridge the gap between a gauge and a data –acquisition system. Hence, the EGS was born. With the ability to replay any recorded data instantly, with a touch of one button, EGS opens up a new chapter in the world of gauges. It’s designed to break the entry barrier and allow regular car enthusiasts the benefits of modern technology without breaking the bank in the process.

Behind this familiar looking tach shape is a very powerful yet extremely simple data-acquisition system that allows you to expand it as you go by the way of “Plug’n play” modules.

With all you data available immediately EGS really is like having a cell phone while most other data-logging systems are like having an old-fashioned land phone.

Physical features
EGS is a non-standard 4” gauge. We have chosen this size for several reasons. In one hand big 5” gauges are difficult to install in smaller cars in the other hand 3 3/8” size is too small to have a meaningful LCD display like the EGS has.

EGS is designed for severe vibrations and harsh environment. The entire construction of the EGS has no hard-mount points internally. All internal components are floating in this rubber-like advanced material called Santoprene. This material is designed to withstand temperatures in excess of 350 degrees Fahrenheit. The rest of the construction is in anodized aluminum insuring longevity, light-weight and great looks.

Shiftlight Module and Control Module (switches) can be mounted remotely allowing the driver to use the EGS comfortably even when strapped in a 5 point safety harness.

Adaptive Alarms
Besides having the ability to instantly replay data in real-time (yes, it’s like watching a movie of what you just did) the EGS has Adaptive Alarms. This is a very powerful feature by itself. It’s like having a guardian angel by your side giving you a peace of mind at all times. Simply tell the EGS what to look for, temperature above 200 degrees, lean condition, too much advance, low oil pressure or anything else. Regardless of what is being displayed at the time when the EGS senses that any of these conditions is taking place it will alarm you and give you a chance to remedy the situation before it’s too late. Adaptive Alarms could save you an engine or two. This feature alone is worth the price of the EGS.

Expansion Modules
What really sets the EGS apart from any other gauge is the “Plug’n play” expandability. Literally, you just plug the modules in the back of the EGS, that’s it. The modules are automatically recognized and made available for Displaying, Logging or for Adaptive Alarms. There is a whole series of modules allowing you to build a very powerful system and really get that power out of your EGS. Best of all, you won’t need a whole slew of gauges. EGS is the only one you’ll ever need.

Sequential Shiftlight
F1 style Sequential Shiftlight is designed to improve your reaction times. It allowes you to anticipate when to shift by preparing you with a sequence of lights prior to the shift point. This also makes it very easy to short-shift. Short-shifting is an endurance racing technique used when it’s necessary to prolong the life of the drivetrain.
There are three yellow LEDs that are activated in sequence starting 500 RPM before the shift point. Shiftlight is automatically recognized by the EGS and can be mounted remotely. Shiftlight Module can be rotated anywhere around the gauge making it easy to match the position with the redline point on the gauge dial.

Wideband Module
This module brings you into the world of professional tuning. Super-fast and super-accurate Air/Fuel ratio is a necessity in modern-day tuning regardless if you’re running carbureted or injected. Developed in cooperation with Innovate Motorsports the Wideband module will get you inside the combustion chamber so you can find ways to get that extra few horses out of your engine.
Multiple modules (up to are automatically recognized by the EGS system. If you are currently running Innovate Wideband you are in luck because you can simply plug it in the back of your new EGS and it will work seamlessly.

OBDII Module
On Board Diagnostics is quickly becoming a popular way to get information from your car that’s not readily available in the instrument cluster. This is good news for tuners because now you can get valuable measurements like ignition timing, throttle position, intake pressure, water temperature and much more. EGS OBDII module works with all five current OBDII protocols including the super-fast CAN protocol. This module works on cars that are 1996 and newer.
All standard trouble codes are displayed in plain English like “cylinder no. 6 misfire” and so on. So you can be prepared for that visit to the mechanic. You can even clear trouble codes yourself.
Another cool feature of the new EGS OBDII module is that it will tell you if your car is ready to be smogged or not. This can save you time and money by preventing you from needlessly going to the smog station.

Accelerometer Module
Accelerometers (G sensors) is how we got our name. Over the last 15 years our G-TECH/Pro Performance Meters have become a household name for car enthusiasts all over the world. Accelerometer module measures forward (longitudinal) acceleration. This is a best way to estimate power gains and losses during tuning. Using G’s to measure power eliminates variables like wind resistance, rolling resistance and makes it easy to determine if your modifications are helping or not. This module plugs in the back of the EGS or can be remotely mounted with an extension cord.

Memory Module
Memory module will significantly increase the recording capability of the EGS. In fact, depending on how many parameters you choose to log the recording can be a couple of hours long. The number of possible recordings goes from 8 to 24. Additional memory module will allow you to hang on to your recordings longer and have more flexibility in storing your data.

8 Channel Input Module
This module makes your EGS a powerful and adaptive data-acquisition system with the ability to accept virtually any sensor, analog or digital. Input voltage is 0-5V. The super-easy user interface allows you to set up any sensor right there at your fingertips. It only takes a couple of minutes and your EGS will be able to interpret virtually any sensor and display the value in the units you choose. The scaling is automatic and even the non-linear sensors are taken care of. Now you can monitor things like tire temperatures, driveshaft RPM, diff. temperature, Exhaust Gas Temperature or anything else you can think of. There is even an extension cable and a screw terminal board included for easy hook-up to the sensors. Finally, data-acquisition the easy way!

TRIVAC Mounting System
So you don’t really feel like drilling mounting holes on your nice dash-board. No problem, TRIVAC mounting system really makes it a snap to install your EGS. Three powerful suction cups make the installation solid as a rock. Aluminum construction makes it durable and long lasting. TRIVAC has been tested to withstand 300lb of weight when used on a clean glass surface.
With TRIVAC you will be able to take your EGS from one car to another. We recommend getting another set of installation cables when doing this so that taking your EGS from one car to another really is a matter of seconds.
