iPhone OBD-II app

Rev by DevToaster is an application for the iPhone and iPod Touch that allows real-time monitoring of vehicle ECU data from the OBD-II port. Rev interfaces with a WiFi OBD-II dongle.

If your check engine light is on or flashing, REV is able to check the engine code, list all of the engine codes stored in the vehicle, and reset the stored codes or check engine light.

Rev is able to monitor real-time; vehicle speed, RPM, fuel consumption, engine coolant temp, fuel pressure, calculated engine load, throttle position, intake manifold pressure, air intake temp, timing advance, mass air flow, fuel level, barometric pressure, EVAP system vapor pressure, and fuel trim.

A brief video of REV in action is after the break.

How much lag is there between the ODB-II and the iPhone/iPod touch? Many PC-based, directly connected, ODB-II programs still have some slight lag. Is the lag with this app really noticeable?

Posted at 6:27 pm on Sep 27th, 2008 by Matthew

With the required adapter (OBD-II -> WLAN) You could easily do this with other equipment, such as the Nokia N810 or PSP.

Interesting project. Definitely trumps the ODB-II monitor plugins available, since you have a more complex system which allows for more available data (though granted, the lag may be up to a second, at the worst.)

ive seen this on a few sites now, and it looks sweet. but, as on all the other sites, here, the “rev” website and the internet in general there is no mention of where or how to get a hold of an obdii->wlan adapter. i dont think they exist.

Not sure about Wifi, but I know there are bluetooth OBD-II readers available. Though the company that developed this software is “working on” a wifi OBD-II.

Not sure how much freedom there is in the software configuration, but they also make USB OBD-II readers, so maybe that would work. Or if you really wanted to go wireless (but can read from a USB OBD-II reader and price isn’t a factor) you could get the USB one, hook it up to a wireless USB hub like http://catalog.belkin.com/IWCatProductPage.process?Product_Id=356042 , and plug the wireless USB dongle into the phone. Extreme overkill.

wow, really hoping someone ports/rewrites this so it runs on a (modded) psp, i already have one of those (posting from it now in fact, this took about two minutes to write)

Posted at 10:40 pm on Sep 27th, 2008 by ritsuki

It would have to be a wifi odbii adapter that can accept ad-hoc connections or else you’re going to need a separate wifi network.

Why not just use the built in serial port on a jailbroken phone?

@craig and m
I work as an autotech and when i was going to college for it we had a scan tool at school that had wifi and blue tooth that could send the info to a computer/portable device in ‘real time’(there was a little bit of lag but it was reasonable) it wasn’t a cheap one tho prolly a $4-5000 scan tool, you can get obd2-usb adapters for under $100 tho im not sure what the iphone/itouch have for ports but you might be able to rig it up to the mini usb port on a nokia n series or to a psp, or maybe use some type of arm board with wifi and plug it into the usb to send the data…you might be able to get away with something like that for under $250 …heres one i found w/ google http://www.obd-ii.de/news.html

Cool. Nice apps coming out for the iPhone. !

Posted at 12:25 am on Sep 28th, 2008 by Jash Sayani

You could get a bluetooth OBD II scantool hardware for $ 170.00 from here http://www.obdpros.com which would allow it to work with the iphone.

Get back to me when there is a version of this for WM6.

The iPhone is a piece of iCrap.
Seriously, who would buy it?

@tubbo

The only crap I see is your blog page design : )

Posted at 8:21 am on Sep 28th, 2008 by chris

Hey now, this isn’t digg, everyone be nice.

But I do agree, the iPhone is rather not worth the hype or money. It can be useful, but having used the non-3G version why the hell didn’t they put GPS in it? Then you could have an OBDII monitor, GPS Nav, Phone, Ipod, and anything else you can think up in one device. Also, doesn’t the iPhone have accelerometers in it? Couldn’t you do something like a 1/4mile time meter and torque meter purely from the Accels?

Posted at 8:59 am on Sep 28th, 2008 by M4CGYV3R

This would be cooler if it had nothing to do with the iPhone.

Posted at 2:05 pm on Sep 28th, 2008 by Skitchin

Does this have the ability to display and update more than just one metric at a time? My Scangauge II can as well as plenty of other things only for 169.00. You could also use the iPhone’s built in accellerometer with a program like Dynolicious which is currently on sale for 12.99 on iTunes.

Hi.. really wonderful model with updated technology.

Why not post details on the PCB for building this yourself, “hacking” I believe we used to call it.

Posted at 12:30 am on Sep 29th, 2008 by nubie

Perhaps someone from HackADay could work on creating one of these cheap-to-produce OBDII-WLan adapters?

straight from the rev site, the reason they haven’t gone bluetooth is because the bluetooth API is locked-down for app-store applications, same for USB.

“@”Chris

Didn’t leave a link to your own page design I see. What does that tell us?

Posted at 3:59 pm on Sep 29th, 2008 by Tubbo & Dubba Tubba

It’s not open as far as i can tell.

Anyway, is anyone out there tinkering with VPW? I’ve managed to get the PCM, BDM, and ICP for my car. I was tinkering with them on the bench and found some very interesting oversites regarding the break symbol and how each module handles loss of communication due to extended break symbol.

I also grabbed a few packets and tossed together a spread sheet to help tear it down.

I added the URL to a related automotive project. It deals with the 7.3L Ford power stroke electronics. Injector Driver Module(IDM) reverse engineering.

Ok, i thought i added a link.

Just incase it doesnt show up again

Hardware is coming soon: http://wrxfanatics.com/blog/2008/10/update-devtoaster-rev-hardware-coming-in-november/

The developers at Devtoaster have given us another tid-pit of information regarding their upcoming REV software. They are expecting their OBD-II WiFi hardware sometime in November. As soon as we know a more exact ship date and price we will fill you in!

Posted at 9:00 am on Oct 15th, 2008 by Eric

The hardware is out for this finally, worth a look: http://wrxfanatics.com/blog/2008/11/devtoaster-rev-update-hardware-time/

Posted at 5:12 pm on Nov 17th, 2008 by Eric

The Bluetooth OBD unit from OBDKey (www.obdkey.com) is a good option for Windows Mobile. It looks like there may be an OBDKey for WiFi in the pipeline too….

Sweet use of an iPhone. I want it!

After a long search through all the “waste of space” blogs, I finally find yours and am happy! Thanks for the informative read, and I look forward to more!

I’m waiting for full diagnostic functions with iPhone, it would be so grate :D

Posted at 2:13 am on Jun 4th, 2009 by Enigma

Anyone know of a cable that would connect OBDII to ipod’s sync jack? I’d rather hard wire than fiddle with wifi.

Posted at 6:18 am on Jun 8th, 2009 by CABNY

iPhone 3G S is gonna rock the smartphone market :D Can’t wait for it to come out.

Hi
Can i use a Bluetooth ODB-dongle with this and my iphone 3g?
Or is it only the wifi that works?

Posted at 5:12 pm on Jul 14th, 2009 by husa550

My REV + Kiwi WIFI also makes all the metrics sit on 33 or 33.3.

I damn hope it can read check codes after forking out hundreds of dollars.

I’ll be trying it on some newer cars than my 2002 VX-II LS1 commodore before I see if it’s buggered.

Posted at 1:55 am on Jul 15th, 2009 by Chris

Ok got the answer for the ‘33.3 issue’ from a utube video comment.

Buy the app! ..you won’t be sorry :-)

And don’t leave the Kiwi Wifi dongle connected for more than a couple of days. I almost drained my large battery after having it connected 2 days with the car parked in the garage.

Posted at 6:29 am on Jul 17th, 2009 by Chris

Yes i remeber dranning by battery the first week and fail after a month, I did not know you could leave it plug in 24/7 …

had to learn the hardway :(

thanks
