I wrote a program to do it, but you need to run Linux on your computer.

If you are running Windows then you could make do with the the VWRX SelectMonitorDump program. Unfortunately this program doesn't have the facility to write to a file, so you'll need to copy the numbers down by hand.

Dump the values from 8100 to 810F. Note down the two-digit hex values from the first column. Convert them to decimal and multiply each one by 50. This is your RPM scale.

Now dump 8110 to 811F. Convert them to decimal. This is your Engine Load Scale.

Now dump 8120 to 812F, 8130 to 813F, 8140 to 814F and so on up to 821F. Use the formula r=14.7/(x/128) to convert each value to an Air:Fuel ratio.

Actually, to save you messing about with a calculator, there's a better way. Just copy the numbers down, convert them to decimal and then enter them into the raw-data section of the spreadsheet that I posted earlier. The converted-data section should be updated automatically.

As an example, if you open the ROM-data file in the ecu section on my website, and scroll down to address 8120, you can see the raw data of the map. If you look at the spreadsheet you should be able to see how they match up.
