ODB-II - DashCommand iPhone App

[carlclarke]

I purchased a WiFi OBD-II reader and installed the DashCommand iPhone app. For anyone who doesn't know about it - the app gives a display of quite a lot of information based on calculations from the OBD-II values. It is not as responsive as a dedicated gauge but it does have a customisable display that can show many gauges. For example I get:

RPM, Speed, Acceleration, Power, Torque, Vacuum, MPG (Instantaneous and averaged over 3 hours), Fuel Flow, Timing, Coolant Temp, Intake Temp, MAF, Fuel Trims, Load, Lambda, Fuel Pressure, Gear Change etc.

To be honest, I am only learning what some of these things mean, I am not an expert. Anyway to help to make the calculations more accurate there is a configuration screen where some values can be entered. I have had a go at this by reading on here and some other sources. My current configuration has a few gaps and of course I could have entered incorrect values as well. So I was thinking, with all of the knowledge on the forum, perhaps some of you could check my values and point me in the right direction for the missing ones. So far I have:

What hardware did you use to connect the obd2 socket to your iPhone

[roger]

I have a Bluetooth odbll transmitter to my Android which has program called Torque on it. Very similar, o guess.

[stewart@boro]

Please can you let me know the make of the device etc
There are quite a few that mention android compatibility but the only iPhone ones I have found are on American sites and cost over 100 dollars

Sorry, on holiday in other car. But basically it was a cheap eBay from China. Less than £20 IIRC .

Thanks
I'll keep looking

Revival!!

Has anybody managed to get the complete set of settings for DashCmd?

I've been using DashCmd for a while on other cars, love it.

I made 2 skin optimized for MR-S: 5 speed and 6 speed :

5 speed and 6 speed

Is it possible to download directly in app  s;) s;)

Just got this and used the settings on the page. Thanks!! Looks good. Will give it a try tomorrow

Dont forget the ratios are different between the MR-S and UK spec cars so the calculated gear number might need some tweaking.

Ah...good to know.

Hello  s:) s:)

Has anyone manage to get a definitive list together of the values like Volumetric Efficiency, etc for an app like Torque?

Interesting, I was wondering if this displayed mpg and it does. I might consider investing in one now. Thanks for the info guys.
