Thread: OBDMPG - MPG OBDII Plugin for RR 6-12-09

I'm getting an error with the plugin appear. I don't remember the exact message, but it is something along the lines of "Error '5'. Invalid Procedure call or argument". This seems to appear sporadicly but always only about 5 minutes after the pc is started. I thought it might be the cable, but I checked that and all is very snug, I've left the obd2007 software running and it lasted for more than 5 minutes (had it running the full trip to the hospital which is about 40 minutes).

I'll try to get the exact message, but I just got back and am tired. I'll post it next time I drive.

I've bought this OBD http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWNX%3AIT
and it works with every software i've tried. (EasyOBDII, ScanXL_ELM etc)

I'm trying with the debug obdmpg.exe file but the result is always "ELM not responding"


Any help?

have you verified your comport setting in the ini file? I was getting the same message until I verified it was conflicting with Xport. moved the Xport ports around and all worked like a charm.

Could be a baud rate issue. Try using the latest release with RR, the baud rate is adjustable via the ini file. The debug exe's have not been updated in some time.

I'll keep this in mind while testing the newest release and give the code a thorough check through to make sure nothing strange is going on.

Keep the feedback coming guys!

Yew, I've played both with Comports and baud rates. I use com3 and 9600 to communicate with EasyOBDII so I believe they are correct.

As for RR, I use the 30/9/07 version but I don't think this is a problem, because it can't even communicate on it's own (with the debug program), how should I expect to communicate from inside RR?

Let me know what information you want from my system and I'll collect it for you next time I'm in the car. For starters, the following is the basic setup I know off the top of my head.

Zotac 610i motherboard with Celeron 440
2GB ddr2
Asus Xonar dx PCI-E sound card
32GB SSD OS drive w/ewf enabled
80GB data drive
OBDIIPro USB. Com 4 9600baud (says it supports 2Mbps...but have never gotten it to work at higher than 9600)

Windows XP SP3
Newest RR version using Carwings skin
Bluetooth GPS on Com3, Xport setup for 6,7,8
GarminGPS com 6
RR using com 8
Foobar2000
BlueSoliel bluetooth stack

mezz64, does your plugin require a "special" chip?

Mine has either the ELM 324 or the 327. Do you support both of them?

Technically the communication class I use is for an ELM 323. However, the communication process on the client end is the same for all ELM chips and it should work fine for any of them.

I use a Chinese knock-off ELM 327 myself without any issues.

Does your obd connect with the debug program even if the obd isn't connected with the car?

I honestly don't know. All my testing is done with the ELM connected to a vehicle while the vehicle is running.
