Could you clear up my doubts about these Ids, they are calculated automatically by specifying in the xml because in my question I use kph 170 via wire in this case it would already be calculated automatically?
Fuel Consumption (Instant)l/100km - id 203
RPM (Calculated)- id 429
Speed (Gear Indicator & Ratio, RPM)KPH- id 39
Fuel consumption (Liters or Gallons per hour)-id 407
Fuel Consumption is explained here:

RPM (Calculated) is meant for vehicles that has no RPM input. Its calculated from speed and set gear ratios. It shows what RPM would be to top gear. This input should not be used if you have real RPM data available.
Speed (Gear Indicator & Ratio, RPM) This is reverse calculated from Gear and RPM. Could be useful on some cases, but not needed if you have normal Speed input.
