I don't know what you mean by "allocating a byte to a PID", but if you 
want to process frames received directly, simply override 
IncomingFrameCan1() (or …2/3/4 depending on your bus).

Reduced example:

void OvmsVehicleXYZ::IncomingFrameCan1(CAN_frame_t *p_frame)
{
   uint8_t *d = p_frame->data.u8;

   switch (p_frame->MsgID)
   {
     case 0x6f2:
       // for example, assuming the SOC is in byte 1:
       StdMetrics.ms_v_bat_soc->SetValue(d[1]);
       break;
   }
}

If you're outside a vehicle context, you can register your own CAN 
receiver by creating a queue and calling MyCan.RegisterListener(). See 
the vehicle module for an example.

Regards,
Michael
