Have been competing in various Tarmac Rallys of late and am getting interesting results on fuel consumption which is stumping me.
Last weekend, 2 day rally, same road and driving style average speed of 70kmh throughout the rev range up to 6500-7000rpm on gear changes.
Day1: 280km's, fuel usage 33.74L's -> 12.05l/100km
Day2: 279km's, fuel usage 18.04L's -> 6.46l/100km
Now that is nearly half the amount of fuel.....same distance, same (hard!) driving style, same roads, same fuel station filling up (98 octane...).
Car drove and performed (seat of the pants) same each day - now i'm worried that there is something fishy going on with the fuel injection and sensors resulting in the car running lean potentially causing an issue.
Ideas???
