Street Dyno, Road Dyno

[9ummi]

hi guys, i came across this on the net and found it quite interesting, the thread seems old and outdated but according to the theory and the technology implemented, these devices are another option to tuning our cars. Im not saying this will produce accurate results, obviously a Real Dyno will be a greater tuning tool, this would be a great diagnostic feature. basically you input various data including engine size, rpm limit, car weight, gear ratios, ambient air temp etc very similar to what the GTECH does. i think it would be a great idea to implement a code or a separate program which will run off the megasquirt sensors to perform these tasks.


DeltaDash On-Road Dyno Testing
EcuTeK DeltaDash Road Dyno feature

DDRD measures engine speed reported by the ECU, many times per second. Based on this, and additional data about the car, such as tyre, gearbox, drag and weight, DDRD can calculate many statistics about the vehicle's performance, based on a simple full throttle in gear test of the engine on the road surface of choice.
Statistics

DDRD will calculate the following statistics:

* Wheel power and torque. Peak figures are displayed, plus graphs.
* In gear acceleration times e.g. 30-50, 50-70, 70-90mph.
* Vehicle acceleration in graphical form.
* See best gear shift points. By plotting vehicle acceleration against vehicle speed for a number of gears, you can see the ideal speed at which to change gear.
* Terminal velocity due to power developed. A vehicle stops accelerating at the point where the power produced by the engine equals the power consumed by the drag on the car. This useful feature calculates the maximum achievable vehicle speed, assuming ideal gearing,
* DDRD will also compare up to 4 tests simultaneously, which allows comparison of the performance of different gears, cars and states of modification.

Using DeltaDash Road Dyno

Setup
Use of DDRD is very simple. Before driving the car, the software must be setup with various physical characteristics of the vehicle in question, such as tyre size, gearbox type, rev limit, mass and drag data. These vehicle characteristics may be selected simply from lists of available options for the various car models. As long as you know the model of car you are driving, this is very simple to do.

Once this data has been entered, DDRD will display a graph showing the vehicle speeds achievable in each gear. This is as much as DDRD can tell you about your car until you perform an in gear test of the engine - see below.

i believe megalogviewer does that also.
i used streetdyno before, it's amazingly accurate. the actual figure might be off, but on the same car (different setups) it's very accurate between runs.

Do you where can I find a version of StreetDyno that may work with Windows Vista? Or, can you send me the one you are using?
