Hey mrfred, I was having some trouble with the mpg portion. The airflow rate g/ms is getting a reading but the "fuel consumption" line shows "infinity" and the "mileage gasoline reads "0". I put speed on top of the mileage gasoline line but I got no changes. Did I miss something? I'd like to post up a screen shot but I don't know how to do that here. Thanks.

If "Mileage Gasoline" reads 0, then that means that either Speed or AFRMAP aren't getting included in the calculation. You've got these items both enabled in EvoScan correct? Assuming the answer is yes, then take a look at the vehicle speed and AFRMAP EvoScan items in the Data.xml file. Make sure that the LogReference is "Speed" for speed and "AFRMAP" for AFRMAP.

That's correct. Fuel consumption was added with EVOscan 2.5. I'm guessing that's not part of the display in this modification for mpg then?
The speed and afr map boxes are checked. Although, I may have checked off the box after the last time I tried to log so I'm going to try again tomarrow(working on the shifter control housing). I am a little confused about which one of these two definitions go before the "Mileage gasoline" line. In the vehicle speed definition, it shows a log reference as AYC_VSSKph? Eh?
<DataListItem DataLog="N" Color="" Display="Vehicle Speed" LogReference="AYC_VSSKph" RequestID="10" Eval="x" Unit="km/h" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="0" GaugeMax="255" ChartMin="0" ChartMax="255" ScalingFactor="1" Notes="" Priority="1" Visible="false" />
This definition here is what I put before the mileage gasoline line:
<DataListItem DataLog="N" Color="#ffad00" Display="Speed" LogReference="Speed" RequestID="2F" Eval="1.2427424*x" Unit="Mph" MetricEval="2*x" MetricUnit="Kph" ResponseBytes="1" GaugeMin="0" GaugeMax="280" ChartMin="0" ChartMax="280" ScalingFactor="1" Notes="" Priority="1" Visible="False" />
Is that correct?

*NOTE* I just tried to log again and it's till not working. BTW, this is a 96940011 ECU I'm working with. I wonder if I'm missing something in the code?
