I am fed up of the Exige not starting on a right hand slope and having to push it to the flat because my gauge reads 10kts out. I know that I should know better and keep to the mileage or even refill at 18 ltrs but I want the car right so I am planning to put a resistor in line to sort this.
An off the shelf Stack uses 0 to 800 ohms range, does any one know if this is the same on the Exige or do I need to start pooring 5 ltr cans in and take readings as per some o level physics experiment
