Okay, I have been searching high and low for the past few hours and alot last night be cant find exactly what I am looking for. <p>I am trying to find an OBDII Port reader for a 2005 Volvo that can support both ISO and CAN networks. Now I have found a few that support this format and can read codes and some sensors in the car but what I need is something that can also flash/burn the ECU with new software. <p>Ideally I would like to download the current specs of the ECU for a backup copy in case something goes wrong. Then either tweak, alter or design all new ECU software that I could load into the ECU and then Dyno it to see what exactly the modifications have done (then retweak......etc...till I get an acceptable software load on there). So what is out there that I can play with that will be able to flash/burn the ECU with new data? Tom, im looking your way <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0">

Bwahhhhhhahahahahahaha ! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"> <p>Oh - sorry - forgot myself for a minute. Short answer - no such thing. If you develop one, you'd have a nice business opportunity.<p>Note, you do not need ISO for the S40/V50 models. They are CAN-only.<p>Tom.

Re: OBDII Port Reader for ISO and CAN networks (tmtalpey)

TOM!!!!!! arrrrrrgh, why must you crush my dreams! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/mad.gif" BORDER="0"> <p>But seriously, how does the PPC do it then? Clearly there is someway to flash/burn the ECU...its just a matter of finding the right communications medium. <p>Is there a way to advance the timing, increase boost, etc... through some of the disgnostic programs out there? Obviously if we can get a flash device then that would be one good use for it. Hmmmmm, the search continues.

Re: OBDII Port Reader for ISO and CAN networks (Tarheelvolvo)

Oh, it's quite a bit more than just comms. Frankly, even if I knew I wouldn't tell you. Well, maybe I would. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"> <p>There isn't a way to advance the timing, increase boost, etc without understanding the contents of the ECU, physically changing them and restoring its integrity check. There are a few tuners who can do this, and as you see they typically get several hundred bux a pop for their services. It is anything but trivial.<p>Tom.

Done some research myself and spoke with the people at Euro Scan. They said that Volvo is very proprietary with their ECU. Most codes and programs are downloaded from a dealership per satelite and whatever. The guy at Euro Scan said that Volvo is very hard to work with and very difficult. So good luck and post if you find any helpful information.<p>Also, the euro scan tool is $3900 ouch! ouch!<p>

Re: OBDII Port Reader for ISO and CAN networks (IwantaS60R)

Thanks for the info guys. <p>Okay, then let me ask you this. If these devices are so expensive, do they work for multiple cars (ie: all cars with the Bosch Motronic ME7 or ME9 systems?) because I might be able to convince my local shop to get one if I help diffuse the cost. Who knows, maybe I can also get some of the profits then, haha! <p>The development of the code I can do myself....I mean thats what I do for my job so it shouldnt be to far off the mark. Plus im in no <I>real</I> hurry to mess around with the ECU, its just nice to be able to specifically tune the thing to what I have in my car. How does Marco from MTE/TME do it then? Hmmmmmm, and again my question about the BSR PPC flash device. There has to be a way to do this! Or are both these guys/devices using what your talking about IwantaS60R and just have their respective companies buy them and regain the cost through charging for the device? <p>I guess the quote of the day for me is "In order to gain the right answer, you must ask the right question." I just dont know what the question is yet! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/tongue.gif" BORDER="0"> <p><I>edit:</I> Whoa, I just looked through those links you posted and thats TOTALLY what I need <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"> Now, to just get them to let an independant shop (ie: me) purchase one and start reprogramming the ECU! Whoo Hoo. Oh, and small p.s. if you guys help me with this and I actually get it working then ill totally let you have any software I develop for free <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> Im for the community (that and I do just fine on the $ front with my current job).<BR><BR>

Re: OBDII Port Reader for ISO and CAN networks (tmtalpey)

Sent them all emails so we will see what they say tomorrow (or later this week) and see if I can get something going. <p>Plus I have always wanted to battle dragons so I guess this is my chance, ENGARDE!

Since these devices all have APIs that allows one to interface with the device (much better than using machine level instructions) one could theoretically write programs to talk to the device and therefore the car. The real challenge is getting into the Volvo proprietary stuff and changing their code without screwing anything up (I know that's what backup and restore is for <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/tongue.gif" BORDER="0"> ). I would also imagine that Marco et al had to "break into" the Volvo code to decipher what's there before they changed anything. That may take a while to do. Also, I'm sure you know that tuning is alot more than changing boost, fuel maps and/or timing. Anyway, keep us apprised of your adventure. <p> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/embeer.gif" BORDER="0">

Re: (Sil-v3r)

Sil-v3r! Good to see you back on swedespeed! How did your CarPC install go? any updates?<p>Anyway, thanks for the info but I dont think Digimoto has reflashing stuff. They have great diagnostic software and for clearing codes but not so much for reprogramming ECU's. Preciate the help all the same!

Re: (Tarheelvolvo)

Okay, so im thinking my CarPC is back in the mix but I want to do some really revolutionary things to integrate it with the factory dash/center console.<p>Does anyone know off hand how to interface with the CCM modules to integrate the volume, pre-set, ECC (climate control), etc... through the ECU. I would assume the code for the entire system would reside in the ECU but im not 100% sure and does the CCM deal directly with MOST or with the CAN network? I tried reading some electrical stuff but it was mixed as to what resided on what sub system. ANy light someone can shed would be greatly appreciated. TIA<br>

Re: (volvoNB)

Why do you want to monitor A/F? You can't really do much to change it. Besides, any OBD reader will show you the O2 sensor reading, which with a simple conversion will basically yield it.<p>The S40/V50 OBDII reported parameters are:<br>Engine RPM<br>Vehicle Speed<br>Load value<br>Ignition timing<br>Intake air flow<br>Throttle position<br>Coolant temperature<br>Fuel pressure<br>O2 sensor #2<br>Short term fuel trim<br>Long term fuel trim<br>Intake air temperature<p>Other values are read only with proprietary tools.<p>Tom.

My bad, I thought you wanted just to read the stuff not write it <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">.<p>My CarPC is going good. Im actually just about done. I just realized my Xenarc screen may be broken so thats causing a bit of a problem. Aside from that Im basically all wired and ready to go. Ill send you a link when I got pics up.

Re: (ukmatt)

I think the CCM is connected to two networks depending on what function you want. A LIN network and the MOST network. <p>I was reading through some stuff yesterday and basically CAN is the more expensive, faster, stable network but is primarily used for critical car functions like the Engine, ABS, SRS, etc... where time is of the utmost importance. LIN is the less expensive and therefore less time critical network that handles events that arent going to cause the car to blow up or end up in a tree such as ECC, Power Seats, Windows, etc... And then the MOST is purely for entertainment and contains your speakers, amp, volume controls, head unit, etc...<p>So do most SAE J2534 pass thru devices access all these networks? I know the VCT2000 would and if I could get my hands on one, wouldnt I still need the "access codes" that might reside in VIDA to reflash/reprogram the systems? I have looked at the Volcano Tellus and that seems to access them all but I dont think it has the correct access codes to allow new programs to be written to the device. Any thoughts on the best way to get the codes? Hopefully H.R. 2048 will pass soon and Volvo will have to give us the access codes! Heres hoping <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/embeer.gif" BORDER="0">

The CCM is definitely connected to the CAN bus and 2 LIN buses.<p>Again - what are you trying to do? The approach really depends on whether you're trying to replace the ICM screen or actually use a CarPC to control all the things the console controls.<p>UKMatt

Re: (ukmatt)

Going the CarPC route.<p>I havent noticed any CAN connections in the diagrams I have looked at but im glad to be proven wrong! As I read it now it looks like two LIN's that deal with all the button pushes and knob turns but some signals (dealing with the audio system, and also the display for the ECC) are sent into the MOST network to be handled properly....otherwise how would you turn up the volume, change bass settings, etc...? <p>Again, this is from what I have read and maybe I read it wrong so feel free to prove me wrong. At least that way I know what to access better to get the functionality I desire. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">
