RomRaider

You are so out of touch with current technology

Oh...

What STI Robot wrote about wifi being overkill sounded dead accurate to me. How is it wrong?

I've got an RCM4400W laying around somewhere I know I have a RCM4000 for sure. I'll see if I can whip something up tonight or tomorrow even if its wired ethernet for now. I even think there is example code in DynC for something close to this so there won't be a ton of writing. Might take a few hours over the weekend, worst case...

I'm telling you, unless you have your head in the sand, integrating Wi-Fi/ethernet is simple as long as you don't try to get fancy and put in webservers and html/cgi based configuration interfaces. Not that those are unachievably hard, they just present the most development time to get right and bug free (and secure). (with the lantronix stuff they come with all that done for you)

Neither solution (ethernet or bluetooth) would be good for flashing; Too much risk.

Don't throw an idea away just because you can't understand it.

Thanks for that insightful reply. All to often we get our panties in a wad when someone thinks differently. If this were nasioc I'd take that first post as Trolling, but here people generally know what they are talking about.

I only suggested bluetooth because the hardware is already there. With one of the off the shelf bluetooth setups you'd only have to write code on the phone to communicate with the module (jailbroken phone of course). With the wifi connection you have to do some hardware work to go from OBD II to something that transmits wifi and then write the software on the phone.

I'd really like to see if you could make something like this work. I googled the microcontroller modules you mentioned. I've looked at the rabbit stuff before but never got into it because of the expense. My major project right now (shameless plug: robotmeter.com) uses much lower power stuff (an arduino/atmega168). I'm mainly a software and interface dork so the easy c/c++ programming worked for me .

GL And I really really want to see someone take off with this.

I'm toying with an arduino (diecimila) in a pinball machine retrofit, neat little micro for cheap.

I did something like what you're working on back in my autocross days on a Rabbit 3000. Had a 240x64 serial graphic display integrated into the factory guage pod housing. But I was mainly after suspension data and used some rigged up 6" swing linear position sensors (1Mohm pots basically) clamped onto the springs of my Cusco Z2's.

I added a Memsic 2125 accel and some fancy code to make these pseudo contact patches on the display. (read: ovals that changed shape/size with load) Later on I used one of the serial ports on the Rabbit to display stuff from the logger output of the UTEC with it.

I had all kinds of stuff wired to the car Now its down to 5 temp sensors, a tiny 1.5" serial OLED display, and 2 NKK smartswitches.

I've never attempted to connect to the OBD port though. Know a link to a primer on subaru's protocol before I start looking for it myself? Its just serial so its not going to be hard to get bits in/out and to an iPod, deciphering the data on the iPod is where I might need the extra few days

Awesome. I also happen to be a bit of a suspension nerd myself. I'd love to see pictures, specs, etc. of that former project.

As for Subaru Select primers I know of the following:
This is the primer from the tari guy: http://tari.co.za/downloads/documentation/ssm.pdf
These guys put wrx engines in vanagons and have some info that might be useful: http://www.vwrx.com/index.php?pg=selectmonitor
Jdash is open source and uses it so you can look at his code: http://jdash.ludicrous-speed.com/wiki/i ... =Main_Page

Found I used the 4400W already.

So... since the X is going to be smoother and cheaper than another RCM4400W, I've ordered that. But with just the out of the box serial redirector example on the RCM4000 I can sort of access the SSM stuff now, I just have to bit bash it manually. That SSM.pdf was most helpful.

How far along are the hardware api's in the jailbroken iphones/ipods?

BTW the connector on the bottom has a basic serial line...not sure if they have programmatic access to it though.

Hardware side works like a charm. I can use Wi-Fi to log on my laptop. Not very good range though, only about 30 feet from the car so no hopes of a cheap remote telemetry system But for $91 after shipping and support components I'm not going to complain more than that.

Still figuring out all the iPod crap. I've only toyed with it until now. But its easier than I thought. Apple really did one heck of a fine job with Xcode. They had to have stole it from someone else

wait so this is actually possible...? i think it would be awesome to be able to tune the car from an iPhone. i would even settle for only being able to switch maps on the fly or logging.

Yeah, sure, of course it's doable, it'll just take time, dedication, and developers. Physically and in the software all the basic functionality to do this is there.

I don't have the guts, balls, huevos, whatever your slang is, to even attempt to do a reflash over wireless when people seem to even shy away from doing it with even a USB hub attached.

Right now its just ECU->Wi-Fi->PC->RomRaider as far as logging.

I've only got a very basic 'viewer' on the touch working (sort of). I see RPMs, Load, timing (total, advance, IAM), and boost. All text, nothing fancy.

Still figuring out how to deal with two devices trying to connect and access serial data at once. Right now if I'm using the PC and try to connect with the touch, the hardware gets funky and needs a reset.

^ You rock.

I want a video It'll get other devs interested.

I didn't even know you could take screenshots on the touch without extra software... 2.0 is really cool..

Video eventually

Edit:

Issues (hopefully all repairable):

Takes about 5 seconds to connect to the ECU on the touch.
I put in a memory leak somewhere so after about an hour, it crashes.
Sucky to look at while your trying to drive (will need a stand or cradle unles you have 3 arms).
Definitely need to get more into quartz and get some kind of graphics going.
