For the ODO function you have no speed input set, try it as below:

 
For the fuel level, you can try adding some filtering as below, unfortunately it only lets you average over a maximum of 5 seconds which Im not sure will be enough but give it a try.  Otherwise you will have to add a resistor/capacitor to the fuel level sensor wire.

Just create a new channel scalled to km/s (multiply km/h by 0.000278)

 
From the AEM help file:

 
 

I can help you with the CAN set up if you first confirm what device you have.  The document you attached is for a device from a company called BPM auto electronics.  It is not a Motec device.

Ok, all the CAN is done, I havent added any of the new channels to displays or whatever but they should now be available.  I have kept all the channel names pretty much as per the BPM datasheet.
The only one that is a bit ambiguous is Fuel level.  He has used 2 bytes like it is expected to cover a large range of numbers but then says the range is only 0-53L.  Just one byte can do up to 255 and 2 Bytes is capable of 65000.  So I suspect he might be sending it as "0.1L" rather than whole Litres but that is not clear. If your fuel level says "500 Litres" when you have it all working then set the scalar to 0.1.

Yep sounds like you got it.  Here's a quick demo:  https://1drv.ms/u/s!AiYbYlZQuRHPqylX67m5Oo57-JVv?e=t3SK3f
