NiMar, I wonder if it has something to do with your use of the "," instead of the "."? I'm not sure if that impacts the calculations or just the display. I'll look into it and see what I can find out.

I'm using 13 december 2007 RR build

4. Again, I think it's the ",". In order for the flash to work I have to strip off the units and round the number, i think with a comma instead of a period the flash round function fails.

Yes maybe... i've never seen floating numbers on flash gauges - is there can be floating numbers? or only integers?

As for the suggestions:
1. Changeable colors more than likely won't be happening, at least not for this skin. As I mentioned in my early post the flash was just a proof of concept, my design efforts are going towards my own skin at the moment.
2. I'm pulling PID's every 1/4th of a second right now, any faster and I get blank data. You should notice a speed increase if you turn off ExtraOBD and only pull the values needed for fuel efficiency calculation.

oh this mean if I pull 4 values - it will take 1 second?
it's not so fast
can you communicate with ELM 327 on 38400 speed, instead of 9600?

Thanks for the comments!

Thanks!
Waiting for new release!

You're indicator problems are because you're using an older RR build without ReturnIndicatorEX function. I'm using the new functions to ensure compatibility with other plugins. An update to the latest RR release (Guino just put out a new one today!) should fix that issue.

Still not real sure on the gauges. I'm using an emulator for testing so I don't have access to dynamic data. Maybe something gets messed up when the values change more often. I can only rely on outside testing to solve this issue at this point.

When I say 1/4sec, i mean that the timer interval to send the commands is 250ms. So every 250ms I send all the PID requests to the ELM. I have no control over how long it takes to get back to me except for the baud rate. I tested out 38400 with my emulator and things were noticeably faster. Not sure if the same results will be evident with actual hardware though. I'm going to see if I can make the baud specifiable in the ini so it can be adjusted by the end-user.

Look for an updated release tomorrow sometime hopefully.

Hmm, I can't seem to get this to work on my setup with XP. When I open the Carwings skin, I am getting all zero in the fields. Here's the step I took to install it. I copied the COM files to windows/system32. Then I copied the obdmpg dll and ini to RR root and registered the file. And added the started plugin command x,obdmpg to menu.skin.

I download the .exe debug application and am getting "ELM not reponding"
I tried changing the port number from 1 to 8. Each port is giving me the same error above. I have the ScanTool software that came with it. The ScanTool is working fine and am getting values from it. Just can seem to get it working with the obdmpg.exe application. Has anyone ran into this problem?

If it's not responding then it's not connected. Are you sure you're ELM is on a port in the 1-8 range? Most people who have had connection problems have solved them by moving the elm to a lower port, double digit ports will not work.

Sorry I'm a little delayed on the update guys, I've been having a busy week. I'll try and get it up as soon as I can.

Unfortunately I'm not going to be able to post an updated version until 11/30 at the earliest. I'm away from my main machine for thanksgiving week and the hard drive in my travel laptop decided to bite the bullet last night, leaving me without the latest code and without a working development machine.

I'll post when I update it as usual just don't expect it for a little while.

It appears on my system that the trip odometer is reading higher than my car's odometer... My trip to work is only about 15 miles and it read almost 30 this morning. What might be causing this? The MPG figures looked accurate based on what I've calculated by hand in the past...

is it possible your trip meter didnt reset to 0 .. would explain the duplicating (15 x 2) I've noticed this sometimes as well. I've also noticed the MPG being calculated while the vehicle wasnt running. If the OBD device is not connected there should be no further calculation.

I'll post exactaly the same problem as colosports posted. Im having the same problem and using com port #4. Everything works fine on this port with scantool s/w and Im sure my device is elm327 based.
It shows only 0s on the obdmpg plugin.
What could be happening?

I watched the trip odometer on RR, and the tenths of miles were going by way too fast. I don't know if that helps at all...
