You do realise that the ECU still adds extra fuel on top of its look-up chart value (from another look-up chart correction factor) during acceleartion until coolant temp hits btween 60-80 deg Celcius? Meaning that 10c resistor will literally pay itself back within the first few miles..

You don't see a 7% gain in fuel consumption over a full tank worth, solely from reduced cold-start idle consumption.
