Hole Shot

The Hole Shot™ server processes data using the DAC32’s 32-bit, 80 MHz microcontroller with 512 kb of FLASH program memory and its 128 kb of static RAM. The system is capable of greater than 1 kHz loop controls and communications. The controller has 16 digital inputs, 16 digital outputs, 16 analog inputs, 8 analog outputs, 4 frequency inputs and high speed ethernet based communications. The DAC32 is responsible for all dynamometer control and data collection while leaving vehicle data collection to optional USB, Bluetooth or wi-fi based modules. The server connects to the dynamometer’s torque and speed sensors as well as the lift control solenoids via a multi-pin harness. The eddy current brake(s) is controlled via an AC/DC controller mounted in a sturdy wall mounted NEMA cabinet.

The Local Web Service

The dynamometer web-based user service can be launched from any modern electronic device equipped with a compatible web browser. Hole Shot is not reliant on an outside internet connection to function but does use your internet connection for obtaining updates as well as data back-up. If your internet goes down your system still functions as it should. The system architecture does not rely on a dedicated Windows PC to function – your software runs on a server that uses a Linux Umbuntu OS and your software is coded using modern Angular4 coding methods. Commonly used devices include personal electronic devices like tablets or phones, laptop computers, Apple products, desktop computers and all-in-one style devices. Common Operating Systems on compatible devices includes Windows, Android and iOS. Firefox, Safari and Chrome have shown to be reliable browsers for Hole Shot. The user will connect to the wireless Hole Shot network and type in their IP address in the browser’s address bar to launch the Hole Shot local web interface. You can access your dynamometer as long as you are within range of the server’s wireless service which varies depending on the layout of your shop. In most cases you will be able to reach the network up to 100-ft away. You can use an ethernet cable to extend the network’s range to all areas of your shop or business.

Clients

Once loaded, the user will enter their personal ID and password to launch the program. Up to 30 clients can be logged into the system at once allowing multiple users to have access to data at one time. One user is the primary user and has access to the actual testing areas of the program while other clients will be limited to capabilities related to viewing live data, review of past runs, entering of new customers and personal settings. Hole Shot comes with a webcam which can be used to stream video during testing. Pulls are automatically recorded so data and video results can be shared with customers. User’s can customize their experience using a variety of settings. Live Displays, graphed results and correction factors can be set by the user to suit their liking. Large smart displays can be set up near the dyno to enhance the tuner’s ability to access the data they need while they keep their primary device’s display simple and focused at the task at hand. Dashboards can be created using a built-in utility that offers various circular gauges, bar gauges, video, drag tree and other controls and data displays.

 

Testing

Hole Shot lets you run power pulls, tune cars at a constant speed, perform quarter mile passes and 0-60-mph runs. It also has a road test feature that lets you adjust road grade or pull a trailer. Starting tests is easy with Hole Shot as the system is optimized for touch as well as keyboard control. Hole Shot offers the user the option to slow down the rollers after a test and provides plenty of different options for measuring power. Load can be controlled to simulate on-highway driving or it can be adjusted to match a user’s selected acceleration rate or % load. Runs can be defined as being between two speed or the user can opt to only select the start speed and Hole Shot will know when you get out of the throttle and clip the data for you saving you the hassle of having to predict end speeds in advance. Hole Shot even comes with a virtual drag strip which can be set up on any Windows driven display. Simply open DragSim and the track will automatically appear when you perform a ¼ mile pass! Or, purchase Mustang’s optional drag tree and have racing events to promote your Hole Shot Dynamometer System!

 

Results Analysis

Hole Shot lets you view your data in tabular or graphical formats. You can print your run tables with data arranged steps of 50 or 100 RPM or choose to list data second by second. You can decide for yourself how you want channels to appear by choosing default scaling, colors and smoothing. You can clip data after runs are completed to rid them of unnecessary data at the end or beginning of runs making sure pulls are as clean and presentable as possible for your customers. View data between different cars or compare one run on your car then another after you’ve made changes. Tag runs as baselines and make comments for each to track progress. Final runs can be tagged and printed using one of several PDF formats available. You can plot power at the wheels or calculated crank power. Choose your correction factor and scientific units – imperial or metric. Everything you need is at your fingertips, literally, as Hole Shot graphing utility is touch friendly so you only need a tablet. No more cumbersome laptop or wireless hand held – just grab a cupholder tablet mount, mount your tablet and now you have hands free access to your dynamometer!

 

The Jbox is the primary vehicle data collection device. We’ve consolidated all of the system’s mission-critical data inputs into one robust, portable device. Power is provided by a DC power cord which connects to your vehicle’s DC power supply. An optional 110-220 AC/DC power adaptor can be added for obtaining power from a standard wall outlet. Communication is made available to the server via a 15-ft USB communications cable. Longer cables are available that are powered making 30-ft cables possible. The Jbox accommodates two (2) wide-range in-line AFR controllers with their 4.9 LSU Bosch sensors. These convenient AFR set-ups can be paired with 15-ft extensions as needed. The Jbox has a primary engine tachometer input that accepts several optional RPM probes. RPM and AFR inputs use high quality M12 connections to make sure they do not pull out and signals are clean and noise free. The Jbox also offers two (2) K-type mini-jack inputs which can be configured for any temperature reading. Boost and Vacuum measurement is made available via a built in MAP sensor and two TTL inputs are available for measuring frequency signals from compatible sensors. Six (6) 0-5VDC analog inputs are available with 5-volts for power. Each analog input is configurable. A Bosch brand weather station is housed inside of the Jbox making conditions compensation easy and convenient. The system comes with a sturdy handle and rubber feet to prevent damage to surfaces. Place the Jbox on a small cart or on the cowl area and make your sensor connections. When connected to the server the system will automatically sense the presence of the Jbox and connection will be made. For details on the sensors available for the Jbox please see our Hardware & Accessories page.
