It's pretty simple really.

When I go to fill up I usually reset my trip and mileage on the car, well since I've now got the car I decide to do that as well to see how well they match up. So I reset the FE then the Mileage(kms in my case) and then I'll get an error.
Believe it's code 11 with message 'division by zero' then the plugin crashes and it then takes me multiple RR restarts to either get it working right, or I just go into the ini and clear the crazy long numbers.
Everything else works great and I've incorporated it into my skin with a whole lot of data. This has happened with 1.4 and 1.4.1. Can't recall if it happened with 1.3 or not, since that was a while ago.

Consider it added to the bug list. When I get back into the swing of things i'll take a look. In the mean time you might want to give the .dll released with the latest source a try. I cleaned up some code and added some GPS features, the bug might have gotten fixed along the way.

Hi my name is Joe i from to italy, i have install in my bmw 320d car the carpc and i use elm interface for read the variuos sensors...I create the application with vb6 that read the more sensors....Can i read with vb6 this sensors?

external temperature
fuel autonomy
medium consumption
instantaneous consumption
battery voltage
liters tank

I succeed to only read:

speed
rpm engine
coolant temperature

thank you

try setting ExtraOBD=True in the ini file

I don't believe that most of the ones you want to read are available in the standard mode 1 PIDs and as such can not be read by this plugin at this time. You can however receive battery voltage by querying the elm with the AT command "RV". This is not a function of the vehicle ECU but rather the ELM interface.

For example:
In order to read the RPM Engine i send with serial connection this string:
mCom.Output = "010C" & vbCr
For speed i send this string:
mCom.Output = "010D" & vbCr

For read the other sensors what tightens would have to send?

Can you please put that into you plugin and create a label for it?????

I'll add it to the list. I'm in the process of moving at the moment so nothing is going to get done for a couple weeks at least until i get situated again.

as a little update with my issue... it seems to be okay if you reset the info while you're moving... that way when it goes to recalculate for the first time it's got values to use rather than the reset 0
I'll give the new dll a try soon.

I also second the voltage reading.

How's the move going?

I'm working on adding some new features and while working through my testing regimen I noticed the MAF was not updating correctly, turns out I had some conditions in place that would only work when someone had a MAF, MAP, and IAT sensor in their vehicle, a very unlikely scenario.

I'm working on the next release and hope to have it published soon, so stay tuned!

Is this problem with the MPG calculation fixed in the latest 1.5 source?
