The features of Delta Dash have been split into these categories:

Delta Dash is currently available for most modern Subaru vehicles. See Supported Vehicles list.

Live Data Display and Graphing

There are two formats available for viewing, Data Display and Graph

Data Display

Analogue live data in real numbers (ignition timing (degrees), injector pulse width (ms), knock correction (degrees) with max and minimum numbers displayed during sampling as well as current values. Up to 77 channels of live analogue data can be selected. (Number varies with ECU).

Digital live data shows the position of ECU switches such as relays and connectors. Up to 53 channels of live digital data can be selected. (Number varies with ECU).

The current version of Delta Dash can read up to 77 analogue and 53 digital channels of data.

Delta Dash features include:

  • Live capture frequency adjustment from 1 per minute to faster than 200ms.
  • Variable selection of data display items
  • Pausing data during capture

 

Graphing

Live data scrolling graphs can be selected with up 4 graphs displayed on screen. These can be selected from the full analogue list supported by your ECU. Features include:

Data Logging

Live data analysis is an excellent tool in itself however when combined with powerful data logging software this makes DeltaDash truly invaluable. During live data capture 4 selectable graphs can be displayed. However all analogue input channels can be logged for later analysis.

There is no need to set up log file names. The file is generated within your specified directory. One click and you are logging as many channels as you like. A typical log file lasting 5 minutes and capturing 8 channels of data is only 150 KB. A very fast log of 3 channels lasting 30 seconds (1 power run) will create a dated and timed file of less than 20 KB .

Having created the log file, this can be imported back into the DELTA DASH and viewed as graphs or real data. Within the graphing option we allow zooming of any area on any channel allowing detailed analysis of sections of the graph down to less than 0.01 sec. The data option allows you to look at each channel. These channel outputs are displayed as real numbers (ms, degrees, km/h etc). The logged data file is created as a .csv file which can be accessed and edited within any spreadsheet program.

Custom Graphing

There is a further development tool in the DELTA LOG which allows further astonishing analysis.

The example below shows a car with a hesitancy as it comes on to boost. The car was driven once only through the area that this fault occurs. The data was logged, generating a log file. Opening this file within DELTA DASH allows detailed analysis to find the fault.

With the custom graphing option enabled we generate a graph of RPM against ignition timing. Looking at 1400 to 2300 rpm we can see nothing strange happening with the ignition.

We assumed that this was not an ignition based fault. Then plotting RPM against lambda to see if it was a fuel based hesitancy. The lambda drops lean between 1400 and 2300rpm.

This is also shown beautifully when comparing output voltage from the mass air-flow sensor plotted against lambda.

This astonishing software is like turning on a light in a tunnel. One power run on a chassis dyno or a blast up the road and in less than one minute have a look at what you can see.

The list just goes on. Think of a problem and DELTA DASH can help you find the answer.

But Delta Dash is not just a data display and logging program...

Diagnostics

ECU Reset
Erase the stored memory to enable analysis of the effect of fuel changes for instance. No more leaving the battery disconnected at night to reset the ECU.

ECU Trouble Codes
Retrieve all of the fault codes that the factory diagnostic tools can. Up to 88 codes displayed for early model year vehicles, and up to 268 codes displayed for later model years, with full descriptions of each problem for a 10th of the price of factory equipment. Both current and historic faults may be viewed. Check the ECUs historic fault log to find out what caused that cough the car had last week. DeltaDash will allow you to diagnose many faults with your car, saving you costly trips to the garage/dealer. Fix the fault and erase the historic code using the ECU reset.

ECU Live Adjustments
Another extremely useful function is the ability to alter idle speeds and ignition timing live on the ECU. If the idle is a little too fast with the air con working or you have picked up some poor quality fuel and you are logging too much knock correction, then slow the idle down or add some retard across the ignition map. When the fuel has cleared, reduce the retard. 2 minutes work.

The package includes all software, hardware and cables to link a laptop to your car.

The product is licensed on a 'per car', or 'all car' basis. This is intended to appeal to enthusiasts and dealers respectively. Product updates for individual cars will be available from the web site. When purchasing the 'all car' license, you will be entitled to all product updates, plus any new car models added to the product within a year of purchase. Note that in this context, 'all cars' means all Subaru vehicles that adhere to the currently employed diagnostic protocol. Cars from other manufacturers will be licensed separately.

If you buy a license for a single car model, and come to sell your car, don't worry, we'll change your license to your new car model. E.g. You might sell your 99MY UK Turbo and buy a 2002MY STI - no problem !

See the FAQs section for system requirements.

Compatibility

Please visit the list of supported vehicles

Every (turbo, non turbo, 4 and 6 cylinder!) 99MY onwards Subaru car that we have tested has worked perfectly with DeltaDash. If your car is not listed, it only means that it hasn't been tested yet. If you buy DeltaDash, and are the first customer to discover an new car which we haven't seen before, we'll give add support for that model to your DeltaDash as a 'thank you' for you efforts. And if you aren't entirely satisfied, we offer a full money back guarantee.

The package includes all software, hardware and cables to link a laptop to your car. Just make sure that you have both a serial port and a parallel port built in to your laptop.

Licensing Options

The product is licensed on a professional user or enthusiast basis. This is intended to appeal to Subaru dealers/tuners and enthusiasts respectively, the enthusiast version being available at a substantial discount to non-profit making users.

Enthusiast Licensing
DeltaDash is available to car enthusiast to use to test and diagnose their own car. The software will work with up to three ECU versions. This allows use on, for example, two cars owned by the enthusiast, plus one car owned by a friend. The software will remember the first 3 cars with which it has been used, and this will form the 3 car license for the product. All software feature updates and enhancements will be available free of charge as a download from the EcuTeK web site.

Professional Licensing
This allows access to every ECU type that DeltaDash supports - this means all Subaru vehicles EcuTeK have analysed that adhere to the currently employed diagnostic protocol. When purchasing the professional license, you will be entitled to all feature updates and enhancements free of charge from the EcuTeK web site. You will also be able to access any new car models added to the product within a year of purchase.

 

DeltaDash Live User Tuning

Live user tuning allows the enthusiast to tailor the operation of their car's ECU to the circumstances in which it is used. This allows optimum use of race fuels and adjustment of the car's performance in several ways.

Please refer to this spreadsheet for availability

This is an extremely powerful feature and is recommended for experienced tuners and enthusiasts only.

How it Works

The EcuTeK Live User Tuning feature consists of several components:

EcuTeK have customised the function of the software in the ECU to allow live adjustment of several engine parameters. These adjustments may be made through the cars diagnostic socket via DeltaDash or via the In Car Dash Kit (see below).

To use this feature you need DeltaDash or the in car kit and must have your ECU reprogrammed for User Tuning by an EcuTeK Dealer. If you already have DeltaDash, you can download an update from the web site for free. Then simply get your ECU updated by an EcuTeK partner.

Adjustable Parameters


Live User Tuning Window in DeltaDash

The screen shot above shows the live user tuning window of DeltaDash. From here, you can alter various engine parameters in real time - that's while the engine is running ! These features are for the knowledgeable enthusiast and allow accurate adjustment of engine operation for special situations. A few examples of when these features might be used are listed below:

When using the live user tuning feature, useful engine parameters related to ignition, boost and fuelling are displayed in real time so that you can see the effect that the adjustments you make are having. Note that the EcuTeK partner who calibrates your ECU may select which features are available from DeltaDash. I.e. If you only want to be able to adjust boost parameters and would rather not have access to ignition and fuelling parameters, then this may be discussed with your tuner.

Because these parameters are not permanently stored in the ECU, there is no limit to the number of times that the parameters may be altered. However the adjustments are permanent, until the ECU is unplugged or an ECU reset is performed. This is in contrast to reprogramming the ECU, which can only be done whilst the engine is switched off, and a maximum of 100 times before the ECU flash memory is worn out.

How to get it

In order to use live user tuning, you must purchase DeltaDash and download the latest version from the web site. You must then have your car's ECU reprogrammed by an EcuTeK partner. Specify that you require the live user tuning option.

An ECU reprogrammed for by an EcuTeK partner, in combination with user tune DeltaDash is truly the ultimate solution for driveability and customisation.
